will it work?
 

ive read the 30x9.50 tire will fit with stock ride height but will a 30x10.50 fit at stock?

yes, may be a bit of slight frame rubbing depending on the tire profile. A BFG AT prolly would a bit because of its square tread face. with stock offset wheels of course.

im not sure what type of tire it is. found em on craigslist with no pic and no tire brand. hopin i can get him to trade me the 20s that came on my blazer when i got it. havin a hard time gettin rid of them.
