Tire rotation

I have an 88 iroc factory wheels I noticed the front say front and the rear are stamped rear, is the offset different? If so does this mean i have to bust tires to rotate.

Yes and yes (unless you rotate side to side).

Re: Tire rotation

Tire rotation with IROC wheels and directional tires can be a expensive practice. Reason: you need to dismount the tires for a front to back rotation.

Re: Tire rotation

They had to offset the front out more because of the size tire they wanted to run on the front. If they had the same offset, the front tires would rub when the tires were fully turned. This is something you can do if you can, find another set of front rims like yours and put them on them back. If you do that then you would have the same offset all the way around then from then on you can rotate front to rear with no more problems.
