Does anyone know if 32 x 12.5 15's will fit on a stock 94 Z71? Any help would be appreciated.

yea, they should fit. i'm running 265's [31's or so] ona '93 4x4 and you should be able to run up to a 295 [33's] with out rubbing on a stock height vehicle.  

watch the width if you have stock inset rims the will rub the frame if i was you i'd go down to about 10.5 but thats just me

Will 285's fit? I have the same truck only it's a '92.

yes it will. all the tires up to 295's [33's] will fit on the '88 - '98 chevy full-size trucks. they are the exact same except for minor changes that were made [dash, mirrors, seats ect.].  

Does that go for stock rims too?  

The stock wheels will interchange as long as they are 6lug.  

What do you mean interchange?  

check all the lift co.s web sites they usually have a what hits what fits even w/ stockers section i.e. skyjacker superlift rancho procomp, blah ,blah,blah  

i think what he means by interchange is if you get a different set of wheels besides using your stock ones, make sure that they are the same 6 lug pattern as your half-ton's 6 lug pattern. but other than that a 295 sized tire will fit on a stock rim so long as it doesn't go over 10.5"

Thanks Griasev that's all I needed to know.
