Maximum Tire Size Allowed.

[Stretch5]

Hi Everyone!
I have a 2020 Big Horn - Built to Serve Edition that came with Falken Wildpeak 275/55R20 tires and I am not a fan as they look like a low profile tire on that size of rim. I am looking into putting larger tires on the factory 20" rims. What is the largest tire I can have on this truck without it rubbing. I am getting a 2" leveling kit put in. I have no intentions of raising the truck from there.
I like the Falken 295/60R20, or the 285/65R20. Will those work? TIA!

Is that what your running? Any pic's

285/60R20 is a good look with only a 2" level.

35-12.5/20 nitto ridge grapplers on stock rims with front leveling and very minor trimming. Just FYI

Anyone know if I could get 305/55R20 Falkens on the OEM 20x9 rims without rubbing?

Here’s 275/65’s on stock rim

Pretty damn close to the UCA’s. You would probably need a spacer and then have to trim some plastic.

This is on stock BTS. Are these E rated and how is the ride with them they look great. The stock BTS rides perfect for me but will eventually need a better tow tire. My 14' bighorn had General Grabber ATX and will go with this brand.

35x12.50R20 Thunderer Ranger ATr $725.00 ride like a dream, no spacers required for UCA’s

No I’m leveled 3” and yes they are E rated. Ride is awesome. Still trying to use to the quietness of RT tires.

Did you have to level your truck for these tires to work?

 

[Stretch5]

Thank you everyone for the replies. I have made the decision to go with the 275/65R20 with a 2.5" leveling/raise kit. Hopefully going to have this done within the next month, once the weather warms up.

I'm getting the 3.5 ReadyLift SST installed but still trying to nail down which tires to get. I'm leaning towards the Ridge Grapplers, but I don't know the max size I can go with without any rub/mods. I have 20x9 ET20 wheels. Looking around the forums, some people say the 35s rub and some people claim they don't. My off roading will consist of camping and hunting but not "4-wheeling" per se. Thoughts?

Why not 35/11.5R20 nittos instead of the 12.5. Should be fine with that.

Yes, I’m lifted 2” front 1-1/2” rear, 35x12.50R20 is what these trucks deserve anything less is unacceptable

Just had a client here that has a 2019 RAM and he put a 4" lift in with the 35/12.50R20LT tires and man did it look awesome!

 

[Stretch5]

Well here is the final decision I made for my truck. I did a lift of 3.5" front and 2" rear. With BFG KO2's 285/65R20.
