No. You can run a lower aspect(225/55 R17) but doing so will throw off the speedometer. R stands for radial, if there is a B it is a bias belt type, D is directional, if there is no letter it is X-Ply. The last two numbers are the rim size in inches.

## Can I use a 235 tire instead of 225?

No, not OK… all tires should be same diameter. the diameter is the same just more contact with the ground. uh… 225/45/17 and 235/45/17 are NOT the same rolling diameter.

## What is the difference in a 225 and 235 tire?

If considering gas mileage, you’ll want a tire with less rolling resistance. The 225, being thinner, has less rolling resistance than the 235.

## Can you put different width tires on same rim?

As a general rule of thumb, it’s safe to fit a tire up to 20 millimeters wider than stock on the original rim. The actual width of the tire will vary depending on the width of the rim: The tire will expand 5 millimeters for every half inch (12.5 millimeters) increase in rim width.

## Which tire sizes are interchangeable?

Wheels and tires are not interchangeable words. 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.

## Can you change tire size without changing rims?

It’s possible to change the size of your tires without actually changing the diameter. One example is if you want larger rims – you can buy tires that compensate for the larger rims by reducing the “height” of the outer tire.

## Do tire sizes have to be exact?

Width and diameter are the two factors that determine tire and rim compatibility. For diameter you’ll need to be sure that your tires and wheels are an exact match, e.g. a 215/65R17 tire will only fit on a 17″ diameter wheel.

## Are 215 and 235 tires interchangeable?

Are 215 And 235 Tires Interchangeable? 215 and 235 tires are interchangeable if they come with the same tire aspect ratio and the same rim diameter.

## Can you run two different size tires on the same axle?

Having two different-sized tires on the same axle is generally not a good thing. If the diameter of the two tires is close, then the rolling radius is about the same, so in the short term, you probably won’t have any damage, but long term, you run the risk of messing up your car’s differential.

## Is it OK to change tire width?

If done incorrectly, changing the tire size can be detrimental to the safety of your vehicle. If done properly, choosing to go with a larger tire size can be beneficial and even increase the performance of your vehicle.

## Does changing tire size affect transmission?

## Can wrong size tires damage car?

## Is it OK to have mismatched tires?

Primarily, you should avoid mixing different tire brands and different tread patterns. There are rare exceptions for approved mixed-tire fittings, but in general, manufacturers do not recommend tire mixing at all.
