So, in going to 35's, is there a tuner out there that will correct the speedo discrepancy? I am running a 21 Power Wagon and want to switch to factory 20" wheels and bigger rubber. Later going to swap out to big brakes.

Look up the Tazer. I have one in my Jeep. Let's you calibrate tires, gears, change a variety of settings. It does not change the engine tune though. It is the go to device with the Jeep crowd.

Will do. Thanks!

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.

What lift kit did you go with? And did you have to replace the shocks as well?

Getting 35x11.50x20 Toyo OC AT3s with 2” Ready Lift leveling kit put on my 2020 1500 Bighorn after Thanksgiving. Have a neighbor with the same. No issues. Tire measures about 34.5”.

Anyone been ballsy enough to try a 37 on ReadyLift 3.5"?

I'm contemplating on doing that ASAP. Would love to hear if anyone has this setup!

I saw one person on custom offsets that showed that set-up with a 20x9 +1. Couldn't actually find the person online though.

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!

I just put on 35/11.50 r20 on Factory 20's with no issues at all !!
I went with the NITTO Terra Grappler G2

Riley,
Did you level your truck out or stock suspension? I'm putting a Ready Lift 2" leveling kit with Toyo AT3 35/11.50 R20s on my 2020 Bighorn on Thursday. Would love to see pictures of your truck.

Can I bring this back to life? Largest size ON STOCK BTS edition or 1500 with off road group?
