My tires are still pretty new so I dont need a whole wheel and tire package. The package Im looking at has an 8" front and 9.5" rear. I know the front 225's will fit on the 8" wheel no problem. Will the 245's fit on the 9.5 without being stretched really bad?

 

It won't be stretched. I had 255 on a 10.5 and it was barely stretched. 245mm = 9.6"

You won't really have any bulge. You'll be fine. 45 series will be pretty thick.

 

I'd love the see what you call "barely" stretched. a 245 belongs on an 8.5" rim. a 9.5" rim should have a 275 on it. If it's just tempoary until the tires wear out, it will fit, but it's not ideal.

 

The factory 18's in the back are 8" wide. So you'll definitely have some stretch but it will fit ok.

 

255/40/19 on 10.5













225/40/19 on 9

 

That's not "barely". The rim is completely outside the tire. That's a major stretch.

 

I guess it's subjective.

 

It wont be like this, but you'll definitely be able to tell theres some stretch











It'll be like what maijik posted or similar to this

 

not even NEAR that amount of stretch. It will be LESS stretch than the wheels I posted. It's 10mm less tire and 1" (25mm) less rim compared to my rear pic, so there is 15mm more tire for the rim than my rear wheel picture.



The sidewall won't be visually stretched.

This is 245/40/18 on an 18x9.5 wheel:

 

I've got 225/45s on 8.5" rims and there is just a hint of stretch. On the back the 245/45s fit the 8.5" rims perfectly.
