Is it ok to run bigger tire than stock?
A friend of a friend has a set of 285s for sale for a decent price. Will these be ok to put on my 04 z71? I'm sure they'll clear, I'm just wondering if it will mess up the shift points on the transmission. I read somewhere that putting bigger tires on can burn your transmission???93 trans am-FOR SALE!

My stock tires are 265s and I ran 285s for quite sometime and did not notice any difference in tranny temp. I think you should be okay, but this comment is based on my personal experience only...I am not a mechanic or even someone with lots of experience. However, I do think that you will need to provide your current stock tire size, transmission info, and maybe your gear ratio for someone to give you a sound answer.

Clearance shouldn't be an issue for you since it's a 4wheel drive, I ran 285x70x17s bfgs mud terrains on my stock 2wd and only had minor rub issues until i did alittle trimming on the plastic innner wall...I didnt notice any difference either in the trans temp, but like said above, im not a mech But i have put over 75k on my 06 in that last year and a half half that was on those BFGs. I did notice however that my speedometer was off by about 5mph. hope that helps.4.8L Vortec | 6inch Lift | Wild Peaks 33'' | K&N Intake | AirRaid Throttle Body Space | 3inch straight pipe dumped at rear axle | BlackBear Tuned | 2 13in JL Audio Subs | 1000watt HD amp, 2.9 cap | Sony Deck | Gibson Hi Flo Cats | HIDs Hi/Los 55watt 8000k |4.56 gears |

I ran 285/75r16e's on my 04 Z71 and had no problems. Only think to keep in mind is that the speedometer is 4mph slow above 55mph.

Yeah its not gonna burn your tranny! The only time I heard was a guy ran 38's on a ranger with a 4 cylinder and crap tranny and had problems but that was because the problem circled on the front!
