A 91 silverado with a 6" rough country suspension lift. How wide of 35" tires can you put on it? It says 35" x 12 1/2" wide is ideal for this application, can you go 14 1/2" wide without rubbing?

 

depends on the backspace of the wheels. you will probably need a wheel with more negative offset. and possibly a wider wheel, like 10" or so wide. if this truck is street driven, you may need fender flares as well, to be street legal. check with local laws about that.

 

I would go with a 12.50 on a 10" wide rim with atleast 4.5" backspace. Should kick your tires out enough so there is only minor rubbing that can be trimmed up really fast. Plus your supposed to go with around a 2" size difference between tire and rim. So if you went with a 14.50 tire you would be looking at wide rim or would be wearing the inside of your tires alot faster.
