Why Homologation Matters
Why The Marking Is Worth Matching
On a premium car, the approved tyre isn't marketing — it's part of how the car was engineered to drive.
01
Tuned to your car
Homologated tyres are developed alongside the car over thousands of test miles, so steering, grip and stability match exactly what the maker intended.
02
Braking as designed
The car's ABS and stability systems were calibrated around the approved tyre. Matching it keeps braking distances and safety-system behaviour correct.
03
Ride & refinement
Approved tyres preserve the exact ride comfort and cabin quietness the manufacturer signed off — noticeable on a luxury car.
04
Staggered & run-flat
Many premium cars use different front/rear sizes or run-flats. We match the correct homologated spec across the car.
05
Sourced correctly
Homologated tyres are often ordered in. We identify the exact code for your car and get the right tyre, not a near-match.
06
We read the code for you
Not sure which mark your car needs? Give us the reg and we'll identify the correct homologation.

Decoding The Marks
What Those Sidewall Codes Mean
Those little letters after the tyre size tell you which carmaker approved it. Matching them matters.
★ — BMW & Mini
The star mark means the tyre is BMW-approved, developed for BMW and Mini chassis and their stability systems.
MO / MOE — Mercedes
MO is Mercedes Original; MOE is the run-flat (Extended) version. Both are tuned to Mercedes' ride and handling.
AO / RO1 — Audi
AO is standard Audi approval; RO1 denotes Audi Sport / quattro GmbH performance models.
N0–N2 — Porsche
Porsche's own approval, with the number showing the tyre generation. Essential for correct Porsche handling and staggered fitments.
OE
Original Equipment approved
An OE-homologated tyre is the exact specification your car left the factory on, co-developed by the tyre and car makers. Fitting the matching mark keeps handling, braking and refinement as engineered. Fitting a non-approved tyre can subtly change how a premium car drives.
Give us your reg and we'll identify the exact homologation mark your car needs, then source it.

Do You Actually Need New Tyres?
Six Signs It's Time To Replace
If any of these sound like your car, bring it in for a free check before it becomes an MOT failure or a fine.
Tread near 1.6mm
The legal minimum across the central three-quarters of the tyre. Below it, it's an instant MOT failure.
Cracks in the sidewall
Fine cracking means the rubber has perished. Common on cars that sit unused for long periods.
A bulge or egg-shaped lump
Usually kerb damage. The internal structure has failed and the tyre can blow out — replace it now, not next week.
Worn on one edge only
A classic alignment problem. New tyres alone won't fix it — the geometry needs setting up too.
Vibration through the wheel
Often a balancing issue, sometimes a deformed tyre. Either way it's wearing your suspension while you drive.
Over 6 years old
Check the 4-digit DOT code on the sidewall. Rubber hardens with age even with plenty of tread left.
1.6mm
The UK legal minimum tread depth
Measured across the central three-quarters of the tread, around the whole tyre. Most safety bodies recommend replacing at 3mm — wet braking falls off sharply below that, long before you're actually illegal.
The 20p test: push a 20p coin into the main tread groove. If you can see the outer band of the coin, your tread may be below the limit — get it checked.
Driving on an illegal tyre risks a £2,500 fine and 3 penalty points — per tyre. All four illegal means up to £10,000 and losing your licence.
Free tyre check — no appointment needed
Pop in and we'll check tread, pressures and condition on all four tyres. Takes 10 minutes, costs nothing, and there's no obligation to buy.

Common Questions
Homologated Tyres — Answered
What are homologated tyres?
Homologated tyres are original-equipment tyres that carry a carmaker's approval mark, such as ★ for BMW, MO for Mercedes, AO for Audi or N0 for Porsche. They were co-developed and tested with that specific car, so they deliver exactly the handling, braking and comfort the manufacturer designed the car around.
Do I have to fit the approved tyre?
It's strongly recommended on premium cars. The car's suspension, ABS and stability systems were tuned around the approved tyre, so matching the mark keeps the car driving, braking and riding as intended. A non-homologated tyre of the same size is legal but can subtly change the car's behaviour.
How do I know which mark my car needs?
Look for a small code after the tyre size on your current sidewall — ★, MO, AO, N0, RO1 and so on — or check your handbook. If you're unsure, give us your registration and we'll identify the exact homologation your car needs and source the correct tyre.
Are homologated tyres more expensive?
They're usually priced with the premium tyre they're based on, and sometimes need to be ordered in. The benefit is that your car performs exactly as designed. We'll quote the exact approved tyre for your car and confirm availability.
Can you get homologated tyres for my car?
Yes. We source the correct OE-approved tyres for BMW, Mercedes, Audi, Porsche and other premium marques, including staggered and run-flat fitments. Give us your reg and we'll get the exact homologation, usually for next-day fitting.
