2023 Stock Z71 with 285/60R20

Love the Copper look.
Did the tire size or brand change, give less of a smooth ride on hwy?
Did it change any built in Z71 digital controls?
Did you try them in the 4wheel drive mode yet?
Thx in advance

I have not noticed any change in driving manners on the highway. They drive pretty damn smooth. It did not change any built in controls that I can tell but I have not used 4WD since putting them on.

What pressure are you running? I purchased a set of BFGoodrich AT’s in the same size and was told by the tire shop I should be running 50 psi or more in them to avoid cupping.

You do need higher pressure because you went from SL’s to LT’s for proper load carrying. Cupping, don’t know about that, and 50 psi sounds high, but in the 40’s is typical. These guys made it easy so you don’t have to look up the new pressure on a load chart.

New to the Forum!

Great information on the tire size upgrades to 285/60/20 with the Cooper AT3 XLT.

Currently have a 23 Tahoe Z71 (without the air ride) looking to get the Newer BFGoodrich TA KO3 tires. Problem is that tire does not come in the 275/60/20 yet. Is there a chance that the KO3 in 285/60/20 on the stock rims could cause a rubbing issue? (On Control Arm based on width, or at full locks with Husky Liner Splash Guards)

Looking for some experiences or other things I may be not thinking about before I spend $1600+ on a set of tires that may rub.

Also, did notice that the OEM SL Goodyear Territory ATs had a slightly larger diameter than other 275/60/20 tires.

Thanks!
