Whats up everybody. New to the site. Lookin to get some insight to figure out the widest tire I can put on the rear on a factory 2000 gmc Sierra. Truck is lowered 2/4 and has a 275/50/17 radial. It's a rcsb turbo 4.8 with th400. Truck won't hook for anything on the street and that's where I want the truck to work. Any help would be appreciated

I just want the truck to be the best it can be on the street. Any thoughts on how to do that??

Depends...if you have a converter it should and it may help on the street. Hard to say for sure. I on the other hand went 3.42s to 4.10s with my 07 5.3 and dropped .64 in the 1/8th but it was 4wd with 32" tires 275/55/20s.

What size is your turbo? You might need a bigger stall if your turbo spools later in the rpm band but that's to much gear for a turbo truck on a 275 tire on the street

Turbo is 80mm. Stall is around 3600. Does bt 32. 2 step is at 3100 and depending on air temp I can't even get in 2 step on street cuz it will spin for 300 feet. IF it's cool out truck will break the tires around 2200 if it's a lil Warmer it'll wait till bt 28-29. I just bought a wider tire as well but its shorter. Got a 315/35/17. Gonna change it all next week
