Biggest tires on stock RST? What if leveled?

madconcept · February 10, 2020

What I’m reading is with a 2” level the widest you can go without rubbing would be a 285 but with a 60 aspect ratio. This is for 20” wheels of course.

If you want to go to a 65 ratio you need to go slightly narrower with a 275 tire.

Jay Teez has 285/60’s

I have 275/65’s. We both don’t have rubbing issues.

Bluerado has 285/65’s and has a slight rub in reverse at full lock.

We all have levels on our trucks.

Hope that helps.

Definently helps me because once the tires I have now will need to be replaced I was considering going slightly wider to give myself a bit more rim protection but then I would have to go with a shorter tire.

I’ve kissed a few curbs and thankfully haven’t done any damage to my rims even with the 275’s!

The BFG’s do a good job deflecting the curb attacks!

285/65/20 with only 2 inch level from ready lift

About a 34.5 inch tall tire and 11.5 inches wide
Very light rub on plastic mud flap when reverse at full lock, not enough for me to trim.

How is the ride quality? Any issues?

The rub was almost nothing to be honest, I had to be full lock going in reverse and coming off a bad driveway angle. It was just touch but not even enough to cut whatever it touched

Good to know. I’ll probably consider 285/65 BFG KO2’s after I burn through my current set to get the wider/even more aggressive look.

2019 Sierra Elevation, front level and 275/65R20 BFG KO2. No rubbing.

Can you post a better picture of the front clearance? Want to see if A gator back mud flap will fit in there.

Thx

Clearance yo the factory front mud flap with the wheel straight.

I could take a pic with the wheel turned if you want.

@madconceptwhat leveling kit are you running?

Chevy212121 · January 14, 2021

Have a 2020 Rst and looking to put fuel off road coupler 20 x 9 with +1mm offset on 275/60r/20 perelli at plus tires. Wondering if it needs to be leveled or if i can get away without it. Thanks

Just an FYI . I just put 275x65x20 on my 2019 Silverado with a leveling kit in the front. I had to remove the mud flaps but that was ok as I'm putting on fender flares.
