The Ford Escort MK2 RS2000 is a legend1. Get the offset wrong, and you will feel it in the steering — and see it in the stance.
The best offset range for a Ford Escort MK2 RS2000 is ET0 to ET+10 for street and period-correct builds. This keeps the wheel positioned correctly within the arch, preserves the original scrub radius, and maintains the steering feel Ford intended. Aggressive builds can run ET-5 to ET-10 with arch modifications.

I’ve had customers from the UK and Australia come to us specifically for this car. One shop owner in Melbourne told me he builds 3 to 4 MK2 Escorts every year, and the offset question comes up every single time. From my experience supplying forged wheels to modification shops, this car attracts two types of customers: purists who want period-correct fitment, and builders who want an aggressive stance without sacrificing drivability. Getting offset wrong means rubbing, poor handling, or a look that just doesn’t sit right. I want to walk through everything you need to know before you order.
What Is Wheel Offset and Why Does It Matter for the Ford Escort MK2 RS2000?
A lot of buyers know what style they want but do not understand offset. One wrong number, and the whole build looks off — or worse, it rubs.
Wheel offset is the distance between the wheel’s mounting face and its centerline. A positive offset pushes the wheel inward toward the car. A negative offset pushes it outward2. For the MK2 Escort, this number directly controls how the wheel sits inside the arch and how the suspension and steering behave.
![Wheel offset diagram for Ford Escort MK2](https://treewheels.com/wp-content/uploads/2026/07/Image-2-wheel-offset-diagram-technical-illustration-infographic.jpg "Wheel Offset Diagram Ford Escort MK2\")
I remember one customer who ordered a set of wheels with ET+25 for his MK2. He had copied the spec from a modern hatchback without checking the MK2’s requirements. The wheels sat so far inside the arch that the car looked unfinished. We had to remake 4 wheels at ET+5 to get the fitment right. That was an expensive lesson.
Why Offset Is More Than Just a Visual Choice
For the MK2 Escort specifically, offset is not just about how the wheel looks under the arch. It directly affects three things that the driver will feel every time they get behind the wheel3.
| Factor | Effect of Wrong Offset |
|---|---|
| Scrub Radius | Changes steering weight and self-centering behavior |
| Suspension Geometry | Alters camber and toe under load |
| Arch Clearance | Causes rubbing at full lock or over bumps |
The MK2 has relatively narrow arches. There is not much room for error. A wheel that sits too far inward makes the car look narrow and unfinished. A wheel that sits too far outward creates rubbing and puts stress on wheel bearings and suspension components. The MK2’s original geometry was designed around a specific scrub radius. When you change the offset significantly, you change that radius. The steering will feel heavier, lighter, or unpredictable depending on which direction you go. This is why I always ask customers to tell me how they plan to use the car before we discuss offset. A show car, a street car, and a track car all have different priorities, and the offset choice should reflect that.
What Is the Stock Wheel Offset for the Ford Escort MK2 RS2000?
Most customers want to know where to start. The stock spec is always the right answer to that question.
The Ford Escort MK2 RS2000 left the factory with a wheel offset in the ET0 to ET+10 range4, depending on the specific variant and market. This range was chosen to give the car a planted, wide stance without requiring flared arches or suspension modifications.

I use this stock spec as the starting point every time a customer asks about replica or period-style wheels for this car. Last year, a UK customer came to us wanting to build a \"factory fresh\" RS2000 restoration. We supplied 4 wheels at ET+8, 13x6J, and he told me it was the most accurate fitment he had seen on a restored MK2 in years.
Understanding the Stock Spec in Detail
Ford’s original offset choice for the MK2 RS2000 was not accidental. It was the result of balancing several engineering priorities at the same time.
| Spec | Factory RS2000 Value |
|---|---|
| Wheel Diameter | 13 inches |
| Rim Width | 6J |
| Offset | ET0 to ET+10 |
| Stud Pattern | 4×108 |
| Centre Bore | 63.4mm |
The ET0 to ET+10 range places the wheel face close to the centerline of the rim. This keeps the load path through the hub as direct as possible, which reduces stress on the wheel bearing5 and keeps steering feedback clean. It also means the wheel fills the arch without needing spacers or flaring. For customers who want a period-correct build, I always recommend staying within this range. It is the safest choice for anyone who wants the car to drive the way Ford intended. If you are restoring a car for shows or road use, this is where you should start. Deviating from this range should always be a deliberate decision, not a mistake made by copying specs from the wrong car.
What Offset Range Works Best for the Ford Escort MK2 RS2000?
The stock range is a great starting point. But not every customer wants stock. Here is how to go further without getting it wrong.
For most street and light track builds, ET0 to ET+10 remains the best range. Customers chasing a more aggressive, flush fitment can run ET-5 to ET-10, but this typically requires arch rolling or minor flaring to avoid rubbing at full steering lock6.

I always tell customers to check clearance at full steering lock before finalising their order. The MK2’s geometry is sensitive to scrub radius changes. One customer in Canada skipped this step and ended up with 3mm of rubbing on the inner arch at full lock. He had to roll his arches before the wheels would clear properly. That could have been avoided with a quick clearance check before ordering.
Offset by Build Type
Different builds have different priorities. Here is how I guide customers based on what they are trying to achieve.
| Build Type | Recommended Offset | Notes |
|---|---|---|
| Period-correct restoration | ET+6 to ET+10 | Matches factory intent, no arch work needed |
| Street daily driver | ET0 to ET+6 | Slight flush look, still safe without modifications |
| Aggressive street build | ET-5 to ET0 | Arch rolling recommended |
| Rally or track build | ET-5 to ET-10 | Requires suspension setup to match, improves cornering stability |
For rally-inspired builds, a slight negative offset can improve stability and cornering feel. It widens the track, which lowers the center of gravity effect during cornering7. But it needs the right suspension setup to match. Running a negative offset on a stock suspension without addressing the scrub radius change will make the car feel nervous and unpredictable at speed8. I always recommend customers running negative offsets on a track build speak to their suspension tuner before finalising the wheel spec. The wheel and suspension need to work together. One without the other is a compromise.
What Size Wheels Are on a MK2 Ford Escort?
Factory size is a starting point. Most serious builders today go bigger. Here is what actually works.
The factory MK2 Ford Escort RS2000 ran 13-inch, 6J wide wheels. Most modern builds upgrade to 15 or 16 inches with widths between 7J and 8J. This range improves tyre choice and performance while keeping the car’s original proportions intact.
![Ford Escort MK2 wheel size upgrade options](https://treewheels.com/wp-content/uploads/2026/07/Image-5-ford-escort-mk2-wheel-size-upgrade-comparison-infographic.jpg "Ford Escort MK2 Wheel Size Options\")
Almost no one building a serious MK2 today stays at 13 inches. The tyre selection at 13 inches is limited, and the performance ceiling is low9 compared to what a 15 or 16-inch setup can offer. The most popular upgrade range we see from our customers is 15 to 16 inches, which opens up much better tyre choice and allows for a more modern performance profile without destroying the car’s original proportions.
Popular Wheel Size Combinations for the MK2 Escort
One of our regular customers, a modification shop in Dubai, ordered a set of 15x8J wheels at ET0 for a customer’s MK2 build last year. The owner said it was the best-looking MK2 he had ever driven — wide enough to look serious, but still clean under the arches.
| Wheel Size | Width | Offset | Best For |
|---|---|---|---|
| 13x6J | 6J | ET+6 to ET+10 | Period-correct restoration |
| 15x7J | 7J | ET0 to ET+6 | Street daily, light track |
| 15x8J | 8J | ET-5 to ET0 | Aggressive street, track |
| 16×7.5J | 7.5J | ET0 to ET+5 | Modern performance street build |
Going beyond 16 inches on a MK2 starts to work against the car’s character10. The wheel arch proportions are not designed for anything larger, and the ride quality suffers without significant suspension modifications. I also recommend customers think carefully about tyre profile when they go wider. A 15x8J wheel needs a tyre with enough sidewall to absorb road imperfections, especially on older UK and Australian roads where the MK2 is most commonly driven. The combination of wheel size, width, and tyre profile all need to work together. Getting one right and ignoring the others will always produce a result that feels or looks slightly wrong.
Conclusion
The MK2 RS2000 rewards careful wheel selection. ET0 to ET+10 is the safe range. Go further only with the right modifications and setup. Tree Wheels supplies custom forged wheels with expert fitment guidance — built right, every time.

"What is the advantage in a rim with a high ET offset value?", https://treewheels.com/what-is-the-advantage-in-a-rim-with-a-high-et-offset-value/. Wheel offset, expressed in millimetres as ET (from German Einpresstiefe, ‘insertion depth’), is defined as the distance from the wheel’s mounting face to its geometric centreline; positive values indicate the mounting face is on the street side of the centreline, placing the wheel further inboard. Evidence role: definition; source type: encyclopedia. Supports: That positive wheel offset moves the wheel mounting face toward the vehicle centreline (inward) and negative offset moves it outward. ↩
-
"Scrub radius", https://en.wikipedia.org/wiki/Scrub_radius. Scrub radius is defined as the distance between the steering axis and the centre of the tyre contact patch; changes in wheel offset alter this value, affecting steering feel and self-centering behaviour (see, e.g., the technical definition in automotive engineering references). Evidence role: mechanism; source type: encyclopedia. Supports: That wheel offset changes scrub radius and thereby affects steering weight, self-centering, and suspension geometry. Scope note: General engineering sources describe the mechanism for all vehicles; MK2 Escort-specific sensitivity is not independently documented in public literature. ↩

"What Is the Correct Offset for Toyota Supra MK3 Wheels?", https://treewheels.com/what-is-the-correct-offset-for-toyota-supra-mk3-wheels/. Automotive engineering references establish that wheel offset determines the moment arm through which vertical and lateral tyre loads act on the hub bearing; greater deviation from zero offset increases the bending moment on the bearing assembly, which can reduce service life under equivalent loading conditions. Evidence role: mechanism; source type: research. Supports: That increasing wheel offset (moving the wheel further from the hub centreline) increases the bending moment on the wheel bearing, raising stress and potentially accelerating wear. Scope note: The magnitude of bearing stress increase is load- and geometry-dependent; the claim that ET0 to ET+10 is specifically optimal for bearing longevity on the MK2 is not independently verified in public literature. ↩

"What size wheel and tyre combo are you able to run on a …", https://www.facebook.com/groups/18987037869/posts/10160530591497870/. Build documentation from marque clubs and specialist workshops indicates that the MK2 Escort’s relatively narrow standard arches provide limited clearance at full steering lock; negative offsets that move the tyre outboard typically require arch rolling or flaring to prevent contact, with the precise threshold depending on tyre width and suspension setup. Evidence role: case_reference; source type: other. Supports: That negative offset values on the MK2 Escort reduce clearance between the tyre and wheel arch at full steering lock, necessitating arch rolling or flaring. Scope note: The specific ET-5 to ET-10 threshold cited in the article is based on practitioner experience rather than published dimensional analysis; individual vehicles may vary depending on suspension condition and tyre profile. ↩

"What is effect of difference in wheel track width on handling?", http://forums.pelicanparts.com/porsche-autocross-track-racing/321946-what-effect-difference-wheel-track-width-handling.html. Vehicle dynamics literature establishes that increasing track width raises the roll moment arm, reducing lateral load transfer per unit of lateral acceleration and thereby improving cornering stability; this is distinct from, though related to, the effect of centre-of-gravity height. Evidence role: mechanism; source type: research. Supports: That increasing track width improves cornering stability by increasing the lateral restoring moment and reducing body roll tendency. Scope note: The article’s phrasing ‘lowers the center of gravity effect’ is an imprecise description of the mechanism; sources support the stability benefit of wider track but through roll resistance rather than CoG reduction. ↩
-
"Scrub radius", https://en.wikipedia.org/wiki/Scrub_radius. Vehicle dynamics research indicates that deviations from the designed scrub radius alter the torque feedback through the steering column under braking and cornering loads, potentially producing steering pull or instability if the suspension geometry is not reconfigured to compensate. Evidence role: mechanism; source type: research. Supports: That altering scrub radius through offset changes without corresponding suspension adjustment can produce unpredictable steering behaviour. Scope note: Published research addresses scrub radius effects generally; MK2 Escort-specific handling consequences at speed are not independently documented in accessible academic literature. ↩
-
"Tire", https://en.wikipedia.org/wiki/Tire. Industry tyre catalogues and fitment databases indicate that 13-inch diameter tyres represent a substantially smaller share of current production compared to 15- and 16-inch sizes, limiting performance and compound options for vehicles retaining factory-diameter wheels. Evidence role: general_support; source type: other. Supports: That the range of performance tyre options available in 13-inch diameter is significantly narrower than in 15- or 16-inch diameters. Scope note: Publicly available aggregate data on tyre production by diameter is limited; this claim is best supported by surveying current retailer catalogues rather than a single authoritative source. ↩

"Do aftermarket wheels affect performance?", https://treewheels.com/do-aftermarket-wheels-affect-performance/. Tyre engineering literature documents that plus-sizing — increasing wheel diameter while maintaining overall rolling diameter — reduces aspect ratio and sidewall height, diminishing the tyre’s compliance over road irregularities and increasing the transmission of impact loads to the suspension and chassis. Evidence role: mechanism; source type: research. Supports: That increasing wheel diameter while maintaining overall tyre diameter reduces sidewall height, decreasing the tyre’s ability to absorb road impacts and degrading ride quality. Scope note: The threshold at which ride degradation becomes significant depends on suspension design and road surface; the article’s specific claim about 16 inches as a limit for the MK2 is not independently verified. ↩
