Tire/Wheel Size Question

[RJB44]

Hi -
I have a set of four like new, polished stock aluminum wheels from a 1990 GMC Jimmy. These have been sitting in a box for about two years now in storage. My truck is a 1991 Blazer with 4 inch lift and 35 X 12.50 tires on 15X10 wheels. I'm pretty sure the Stock wheels I have boxed are either 15X7 or 15X8, so the 35's won't fit, but what is the largest tire I can get on those stock rims? - 33 X10.50?

Thanks

if they are 15x8s the 35s will work just fine

12.5's will fit and work just fine without issues on 15x8's. Hell I know someone running 13.5's on 6.75" wide rims and has never popped a bead.

i'm running new kumho AT's 33x12.50R15s on my stock aluminum rims with no lift and they fit fine. i think the rims are 15x7

Yep, I'm running 35 x 12.50's on 15x7. Bought them from a Toyota guy who needed the narrower track granted by the skinny wheels. While I was initially concerned, he had run them for years that way and I've been running them that way on my K5 for 3 years now with no problem. (see sig pic for how they look)
