I'm looking to buy some stock alloy (4 spoke) rims to replace my '94 4X4 stock steel rims. Set I'm going to look at have two that are 225/75/15 & and two are 235/75/15. Seller said they are stock and came off of a 4runner.

Is it normal to have front and rear tire sizes different? Is it ok (mechanically, not cosmetically) to run smaller in front & larger tires in rear ?

I currrently have 31X10.5X15's on my truck. Debating whether to pay to have tires taken off my steel rims and mounted on alloy rims...or....just run the smaller tires that are already mounted on the alloy rims for now.
Thanks for any advice.

You'll be fine as long as you don't put it in four wheel drive. No, it is not normal, and absolutely not recommended. Move your tires over. And if the guy who you are buying from said that's OK to do, he's jerking your chain.

You want to run the same size tires front and rear to limit any binding when you are in 4WD.

In general you want to run the same front and rear, yes. But the difference between those sizes is less than a half inch which is within variance of unevenly worn tires of the same size. I think you could get away with it.

But unless money is really really tight, just buy some cheap NEW tires of all the same size or get your 31s mounted on the wheels.

Thanks for the quick replies guys. Yeah he sounded like he wasn't too mechanically inclined. I knew that it would cause problems if I put it in 4wd, but wanted to check on the 2wd aspect.

He is asking $225 for rims & tires, so if they are both in great shape so $200 cash would be a good deal. Then $25 a wheel/tire to switch my 31's over & balance.
Thanks guys...

In 2WD, you are good. But what fun is that?

Ya know, though... I have heard of mud guys running a tire one size bigger in the front...makes is spin just a little faster, therefore making it easier to keep going straight. So maybe if you put the big ones in the front... <img src="/forums/images/graemlins/smile.gif" alt="" />

I'm looking at another set of rims to buy. They look anodized though and I'm not sure if I can polish that out or not.
Anyone have experience restoring alloy SR5 wheels to shiny condition? You think these can be restored with some hand buffing ?
