I have a -16 offset 20 by 10 and a 12.5 wide tire would need some trimming. I have factory size tires with a leveling kit and I had to modify mudflap a bit.
Traded in an 18 Denali for this 18 SLT. Had vibration issues that they just couldn’t figure out. RC 2” level with 275 60 2 Hankook tires. Happy with the look and even happier with the ride! No more vibration!
Here’s my 18 SLT I picked up. Kept it simple. Did a rc 2” level and 275 60 20 Hankook tire and a little window tint! Traded in a 18 Denali that I had all sorts of vibration issues . Couldn’t be happier!
Do you have any rubbing issues? I currently have a 285 55 hankook on my truck and sometimes wish I had more tire. I have 2” leveling in front. That looks really good. How does it drive at 75-80 mph?
I’m curious if the dealer checked your front drive line? Took mine off and brought it in to a drive line place. It was so bad they couldn’t balance it. They made me a new one and all problems went away. Less than a year old.
