I was wondering if i was to put oversized tires onmy truck when stocks run down, would it void my lifetime warranty? I dont want to lift or anything just a bigger sized tire. Also what is the biggest tire you can fit on the 20 inch rim without it rubbing. A little rub is ok alot is not. Thanks for the help.

 

u might be able to fit 33 or 35 inchers. shoudlnt' rub at all. it won't rub as far as height goes it will rub when you turn which a lift doesn't stop that. you may need to get wheel spacers to push the wheels out farther.

won't void ur warranty. they have to prove ina reasonable way by law that those tires would void the warranty. which they won't be able to in most situations. now if you put 35's on and do powerbrake burnouts all day long then yea they will probably find a way to void it.

 

35s usually require a leveling kit, and that could void your warranty on some front end suspension items.

33s are basically the same height at the stock rubber that comes on the 20" wheels.
