How to read a tire size
A tire sidewall carries the whole specification in one string. Take P265/70R17 115T:
- P — service type. P is passenger, LT is light truck with higher load capability and different pressure requirements, and no letter indicates a metric European sizing.
- 265 — section width in millimetres at the widest point.
- 70 — aspect ratio. Sidewall height is 70 percent of the width, so a lower number means a shorter, stiffer sidewall.
- R — radial construction.
- 17 — wheel diameter in inches that the tire fits.
- 115 — load index, a coded maximum load per tire. 115 is roughly 1215 kg.
- T — speed rating, here 190 km/h.
Load index and speed rating are not optional detail. Fitting a lower load index than the vehicle requires is a safety failure and in many markets an inspection failure, regardless of whether the size matches.
Why one vehicle has several correct sizes
Manufacturers approve different sizes for different trims, wheel options and markets. A base trim on 17-inch wheels and a top trim on 20-inch wheels are both factory-correct for the same model year. Winter packages often approve a narrower size on a smaller wheel deliberately, because a narrower contact patch cuts through snow better.
The authority for your specific vehicle is the placard on the driver door jamb, which lists the original sizes and, importantly, the cold inflation pressures that go with them. The tire currently fitted may not match it.
Changing size
- Keep overall rolling diameter within about 3 percent of the original, or the speedometer, odometer, ABS and stability systems all read a vehicle that is not there.
- Plus-sizing to a larger wheel with a shorter sidewall usually sharpens steering response and worsens ride comfort and pothole resistance.
- Match or exceed the original load index and speed rating.
- Check clearance at full lock and full suspension compression, not in the parking space.
- Keep all four tires within the same size and, ideally, the same model on an all-wheel-drive vehicle. Circumference mismatch strains the centre differential.
The spare and the pressure monitor
A temporary spare is deliberately a different size and carries its own speed and distance limits, usually printed on it. It is not a licence to postpone the repair. If the vehicle has tire pressure monitoring, sensors may need to be transferred or relearned after a size or wheel change, and a warning light that stays on after the change is a job that is not finished.
What these pages contain
Each model-year page below lists the tire sizes we hold for that vehicle, separated by trim or wheel option where the manufacturer publishes them separately, rather than reduced to one headline size. Sourcing and corrections are covered in our methodology and editorial policy.
Always confirm against the door placard on your vehicle before buying. If a size here does not match your placard, trust the placard and tell us through the contact page.
