tire size??

anybody know whats the biggest size tire I can put on the rear of my skirted 92 caprice. right now I have 225/75r15 but I would like to go wider. thanks..

years ago I used to sell tires & we had what was called a "tire fitment guide". This guide would tell us (in most cases) what larger size tires would fit a particular vehicel. I would think tire stores would still have something like that. (I hope)

Just go measure it.

Here's a good tire size calculator to get some tire dimensions.

245/60/15 on stock rims. i have em on my caprice with old Z28 rims but the width and offset is the same as the stock rims. i dont have skirts but they would clear if i did.   cop cars run 225/70/15 and 235/70/15

thanks for the help all..

Do you know the backspacing for stock rims and what year is your caprice?
