Upgrading Tires On 07 Nbs Sierra Z71 4wd: Bfg At 275-70-17 E Or 285-7

wtmcnair · June 22, 2010

It's time for new tires on my 07 NBS Sierra crew cab Z71 4wd and I'm looking at the BFG All-Terrain T/A KO 275's verse 285's. BFG only makes the 275's in the E rated 10 ply tire which I don't need. If I go with 285's I'd be able to get the D rated (8 ply) tire but would have to level my truck to make them fit. Any suggestions, opinions, and pictures are greatly appreciated!

I have 275/65/18's on Revo 2's on my truck with a 1.5" level. Check out my sig.

Thanks for the posting; you've got a sweet truck. Those 275 Revos look good. I've got some friends with the Revos and they like them a lot but I'm going to stick with the BFGs. My brother is about to get a new set for his Silverado w/ 18's like yours so I'll definitely pass it on to him to check out. Thanks again!

im pretty sure you can clear 285/70/17 without any lifting/leveling

ive had the basic size (32.5-32.8 X 11.2-11.6)

on almost all my hd and 1/2 ton trucks.

you can also turn up your torsion key 1 bolt turn or less without really disturbing things and needing an alignment

In my pic are 285/75/16....32.8 X 11.4

and i had them on before i touched the keys/torsion bars, it was close but no rubbing.

Good luck
