Hi guys, been running 35 12.5 20 pro comp a/t for awhile now, tread is running low and I’m looking to switch up in the fall. I’ve fit my current setup with lots of room. My truck is a 2013 1500 with a levelling kit. Just curious if anyone has ever ran 37 13.5 20 on just a level, and what to possibly expect.
Thanks

Easiest way to tell is turn your 35s to the point when they're closest to anything add an inch in diameter from the tread and see if it touches. And also add 3/4 inch to each edge. If you're close do some homework some companies measure diameter from the top of the tread some from the bottom so if you have a tires thats measured from The bottom of the tread you'd be a 37 but from the top of the tread you'd be 38+ inches I've done it on an older truck I was measured perfectly and when I installed the tires I needed to do alot more work to make em fit properly. Just a heads up so you don't do the same lol. Some companies do the same with section width too but that doesn't affect as much.

man with my 4.5/3" lift, my 35's grabbed the inner liner until I had to cut lower portion out.

I figure there will be cutting. On the bottom half of the bumpers at minimum. Possibly some. Fender heating and tucking as well.

What year is the truck and what were the specs on the setup? I’ve been running these for awhile with no issues whatsoever on your average 2.5 level

well my 2015, had a level and 20x9 with 0 offset on 285/65/20 (34.5) no issues, then added the 4.5"/3" lift with 20x10 and 35x12.50x20 and slight rub, just took off the little knob on bottom. Had to do both, 2015 and 2019 (same lift and tire setup)

What are the specs on your wheels and details on your level ?
I run 37x12.5x17 with a 2.5-2.75 level, 17x9 -12 offset wheels, but i don't have the factory bumper. You aint running 37's on a level with that yuuge bumper for sure without shaving the bumper bottom corners, then you'll have to shave the back of the wheels wells if you're running factory caster.

You'll either cut your factory bumper to fit or go aftermarket.

Even with a lift anything short of the Rebel/Warlock bumpers will definitely need cutting.

However, it can be done :favorites37: post the pics:evil27:

2.5 level 20x9 0 offset 35x12.5x20 currently. Was looking at 37x13.5x20 but 12.5 wide might be a more reasonable option.
Checked it out at full lock and it looks like it’ll be a tight fit without a trim or new bumper. I’ll try to post the pics on here if I can, looks like it ain’t gonna let me for some reason
