got a 91 extended cab with 21575r15 on stk. rims with rear abs.
wanted to go to bfg k/o @ 235 75r 15 & was told they'll rub in hard turn
plus in new jersey there's a law about running same size tires all around ???
even though i only got rear abs .
any input ???
thanks

 

I had 235/75/15 on mine a while ago. they were on the rims when I bought them. but I had some minor rubbing when turning. but it was nothing more then a hammer could fix.

I ended up taking them off because the got bald and blew a belt.

 

I believe it comes down to if your truck is 4WD or 2WD, at least that what it appears when looking at the 1990 service manual.
For 2WD trucks, it lists 195, 205, and 215 /75R15s, while for 4WD trucks it lists 195, and 235 /75R15s.
My 1996 4WD came with 235/75R15s from the factory, and, of course, no rubs.

 

I have a 91 reg cab w/4wd and it has the 235/75R15on it with stock rims. I have no rubbing at all.

i have 235 75 15 on mine they dont rub at all, also had those on my s-10 they didnt rub either

 

I'm having to replace my tires for that same reason. I bought a 92 2wd club cab with 235's. They are rubbing, so I'm switching to 215, either the Goodrich Radial Long Trail T/A or Uniroyal Laredo All Season AWP. They're good looking tires. Goodrich also has the All Terrain, but they're too much for what I need. From all of the reading I've done on this and everyone I've talked to, 215's are as wide as I can go without modifying anything. 4wd's can take the 235's though.

 

mine is 2wd and 235's dont rub

 

my 235's only rubbed on my fender a lil bit. but thats probly cause I lowerd the front about 1". so you shouldnt have any problems.

 

No rub on mine.

 

No rub either on my94 4x4, even my original spare tire is a 235
