RC 2.5" inch lift and 35 inch tires

[Z2Z]

Thanks for all the replies. I come from Vettes, but I'm looking forward to starting to play with this truck

[mayfieldjeff]

i bought my ridge grapplers right before they came out with the new sizes. i would love to have been able to get the 35x11.5. thats ok. once i wear these out i may take the level kit off and do a proper 4" lift and put 35's.

Well lets see if hes telling the truth, my tires and wheels will be here hopefully next week.

Do you have a tune? The only reason I got 33s is because I was told 35s would kill my 3.43 rear end. How's the loss off power?

I have the 3.43 gears in my 2015, and I don't have any issues with 35's on my truck. I also do not tow anything, but normal driving it is just as responsive. In my opinion this is not as much of an issue on the newer vehicles as is was on older trucks.

I wanna say either 4.5 or 5 I think! Don’t remember off hand

Well i have a 285/65 R20 on stock 20's on a 2.5 inch front level, and a 2 inch rear level with very little rub.  The rub is so minimal in fact that i hardly ever notice it.  You can see the extreamly little difference between the 35 x 12.5 vs the 285/65 R20.  Also provided some picks.

 

	285/65-20	35/12.5-20	Difference
Diameter inches (mm)	34.59 (878.5)	35.02 (889.6)	0.44 (11.1) 1.3%
Width inches (mm)	11.22 (285)	12.52 (318)	1.3 (33) 11.6%
Circum. inches (mm)	108.66 (2759.89)	110.03 (2794.76)	1.37 (34.87) 1.3%
Sidewall Height inches (mm)	7.29 (185.25)	7.51 (190.8)	0.22 (5.55) 3%
Revolutions per mile (km)	583.12 (362.33)	575.84 (357.81)	-7.28 (-4.52) -1.2%

Hey all. I used this forum for my purchase so wanted to give input. Have a 17 Sierra with a 2.5 RC level. I was able to fit 275/65/R20 BFG KO2s easily with zero rub. Not sure you could go any bigger w/o lots of trimming.

looks good!!! How much has the ride changed?

3.5” level with 35x12.50 stock 20’s. 1/4” wheel spacers in the front. Nothing in the back. Only rub a little bit when reversing on uneven surface. No trimming done either. It can be done but would only do it on stocks because of offset issues on other rims. You would rub a lot more if I wasn’t on stocks.

Yes you can fit a 12.50 wide tire. You will scrub the sway bar at full lock but its easy to avoid and there was defiantly a big height change with the tires.

Why can’t I see the pictures. Smh

[Chippopotamus]

They will fit. I have a 2018 Sierra with a motofab 2.5 inch leveling kit. With some minor trimming I was able to put Nitto Terra Grapplers 35 x 12.5 x 20s on and the only time it rubs is when I am backing out of a parking space at full lock. I wish I had a picture but I have had the tires on for maybe a year now and have had zero issues other than some minor rubbing.
