Time for new tires. Need help.

Hello, This is my first post.
I have a 70 th anniversary JGC 2011. 5.7 Hemi and pretty well loaded. No front camera and no auto suspension It came with 20" rims with 265/50 tires.
I wan't it to look like a JEEP so can i put 285/65 r20 all terrain t/a BF Goodrich tires on so it looks more like the 2015 Trail Warrior? And if not what do i need to do?
Thanks

Re: Time for new tires. Need help.

As long as they don't exceed ~32" in diameter you should be fine. Don't forget you need to change the spare to a tire of the same diameter that you install on the four corners. You'll also want to note that your SPEEDO and ODO will not be accurate after up-sizing. (can't be adjusted)

I have 275/55/20's. I can't see 285/65/20 fitting. That's almost a 35" tire. You'd need to do some work

Re: Time for new tires. Need help.

The dimensions on the Tire chart lists it as 32.3" ?

Re: Time for new tires. Need help.

I think I miss quoted that size. You are right with the 35" How do you like your 275/55 R 20's?

I have no rubbing issues and really like the tire. Here are some more pictures.

I believe your last statement about the speedo and ODO in not correct. I adjusted my tire size using a DiabloSport inTune i2 I2012. My speedometer is now correct after installing bigger tires 31" (measured mounted and not by manufacturer specs which list them as 32"). I verified my speed with two different GPS units and it is accurate. Also, I didn't get any ABS lights or anything else as previous years that some people had issues with the tuners.

My statement is correct with the caveat that I forgot to mention that one can use a (very expensive) Diablo tuner to do it. Dealers can't change it and that's where most users would turn. Very few folks are going to be willing to make the investment in the Tuner. It would have been nice if Jeep included some adjustment options accessible to the dealers, but I suspect that they don't really want folks changing tire sizes for various "legal" reasons...

I agree the tuner is expensive but I think the benefits of having the correct tire size makes it a little easier to justify the price plus you can tune for more power.
