Tire Size Question

[campalmer]

I have a 2020 Ram 1500 with a 3.5in lift on it. Currently have stock tires 275/55R20 on stock rims. Looking to move up in size to fill the wheel well. Am I able to run 275/65R20 or 285/65R20 and not have any rubbing issues?

You should be good to run either with that much lift. It also depends on your offset on your wheels, so if you have that number people here can definitely help! Welcome to the forum as well.

I will be running them on stock rims.

So 275/65's will fit no problem, the 285/65's should clear, but you might need to trim.

if we go with the taller ties, do we need to adjust the speedmeter to make sure the truck can Shift properly and the speed shows correctly?
The biggest issue that holding me back to go with taller tires because people say the truck won't shift in the right time and my speed will be off like 5 mph if I go 70+ mph.

I've read that it does change the shift changes. I would advise to adjust if possible.
