285/70/18 - 2022 Sierra 1500 Duramax

[pveale]

New 1500 Duramax 4x4 with factory 2" level and 285/70/18 Ridge Grapplers.  NO RUB AT ALL

I had 285/65/20 on my 2019 Z71 which also had a factory level - these rubbed at full lock in reverse...

Looks great

Looks good! I'm thinking about doing the same. How do you like the Ridge Grapplers? How is the road noise? That's my biggest complaint with the Duratracs. 

 

Tire calculator says 285/70 is 5% taller - right at 33.7 inch tire. Speedo would be off 5%. Probably would not work with factory spare tire.

When you say factory level is that the 2” lift from gm that’s on at4?  Do you have the rear installed or just front?

[pveale]

I'm not 100% sure... Its the GM leveling kit they install at the dealership. I think it may only be 1.5" or 2" max.

Its only on the front axle. Nothing on the rear.

Also.. in regards to the road noise - its not extremely bad like Toyo M/T or Wrangler Duratrac but I would say it's slightly more noticeable than the BFG All Terrain KO2
