Hmmm.. you can fit either or. on 19s, 225/35/19, on 20s, 225/35/20.

But there is one catch: gotta roll dem fenders boi!

you can easily figure this stuff out with a calculator.

take the rim size and multiply it times 25.4 (wheels are in Imperial inches, you need to convert to metric)

then, take the first 3 digits (width) of the tire, multiply this by the aspect ratio (second 2 digits) divided by 100 (so, 40 would be .40).

then add the two numbers together, then you will have the overall size of the wheel/tire combo.

for example:

205/55/17 overal diameter is: 414.8 + 102.5 = 517.3MM (or 20.36")

So, now you need to figure out how changing the overall tire size (new tires) will affect this number. Your goal is to get the new tire/wheel diameter size to be as close as possible to the number above.

Another example:

414.8 (17" wheel) + 101.5 (225/45) = 516.3MM

That is the overall diameter of the factory 17" wheels and 225/45/17 tires.
While not a perfect fit, being off by 1 MM is as close as you could hope for.

Hope this helps,

PS: To calculate wheel sizes, just factor in the wheel size into the overall diameter of the tire/wheel combo.

you are correct, I was going from memory.... but, the equations remain the same.
