Largest Nitto Ridge Grappler

[NEFLSierra]

Hi there. New to forum, thanks for the help/advise.

 

Have a 2018 GMC Sierra Crew Cab with stock 20 inch wheels and have a 2'' level kit. Really like the Nitto Ridge Grapplers and was hoping for some advise on the largest size that will fit with my stock rims . Looking at the 285/60/20. trying to get the tallest and widest tire

I tried 305/55/20 and they rubbed a lot.  Good luck.

I have 285 50r22 (33.26) terra grappler g2 on mine with no rubbing at all when I had just a 2" level.  The tires you are trying to run are about a 1/2 in taller and not quite as wide, I think youd be ok.  I put 2" spacers on and the rubbing was undriveable though, good bit of cutting wouldve been necessary.

 

Edit: The offset is going to come into play.  Maybe trying finding some similar set up on the custom offsets website.  You can narrow it down a bunch of different ways to get something similar.

You can fit with no trim atleast a 275/60 or 285/55. May have to Trim with 295/55 & 285/60.

im running 295/55 toyo's on my truck. I have a 2" level and they rub the UCA at full lock. Take a look at the Toyo Open Country RT. they are cheaper then the Ridge Grappler. I ended up getting all 4 for $1250 installed
