Most of the cars are engineered to tolerate way more wheel size variations – first, because not all 225/65R17 (or whatever) are made equal and second because of the possibility to use snow chains. Snow chains can add up to 30mm in each direction (and more if you are novice and don’t tighten them properly).
Why are my tires two different sizes?
The simplest explanation of differential is that it lets your wheels spin at different speeds. This is important because when you turn your car, the wheel with less distance to go (the inside wheel) will roll more slowly than the wheel on the outside.
Why does my car have different tire sizes?
Tires are a part of the wheel setup. For instance, your vehicle has a set size of rims, but you can buy different sizes of tires to fit those rims, as long as the middle of the tires is the correct size. That being said, a vehicle with bigger rims will often be able to fit larger tires than other vehicles.
Is it okay to have two different size tires?
No matter what type of vehicle you have, having mismatched tires front to back can sometimes cause handling problems. Granted, this really doesn’t happen that often, and it is usually no problem to have different tires on a car.
Do all 4 car tires have to match?

Will different size tires affect transmission?

Can you have two different tires on the same axle?
No. Mixing different tread patterns across the same axle is not allowed. The identical tyre model and tread pattern must be fitted for a single axle. You can, however, use different tyres on a separate axle – just as long as they too match each other.
Can I mix tire sizes?
Don’t mix tire sizes. All four tires must be marked with the same tire size unless otherwise specified by the vehicle manufacturer. This also applies to winter/snow tires. Don’t mix radial and non-radial tires.
How much difference in tire size is acceptable?
