285 55 20's

I put 285 55 20's on my truck with no problems, probably could have gone a tad taller, but wanted to retain close to stock diameter. I tow a ton and didn't want to mess with MPH calculations or rubbing issues. Pretty happy with the results.


Toyo ATII Extremes with Fuel Cleaver Wheels.


Bad picture, but you get the idea.

This is a great thread, let's keep it going.
I might have missed it but has anyone (or could someone) post some pics of stock rims, no key adjustment with 285/65 r20?...that is what I am looking to do.

Largest tires on a stock 2017 2500 High Country?



On stock wheels Iím running the 275/70/18 Nitto Ridge Grapplers. 33.2 high and 10.8 wide

I could go a touch bigger but there is no benefit for me.

Here is a comparison chart for the 286/60/20 you are asking about. My tires can give you a visual comparison.

Stock rims? That is the size I'm looking at

I just got a set of Michelin 275/65R20 for my 2017 Denali . It currently has 265/60R20. How much will this affect the speedometer?

Has anyone tried Cooper's new Discoverer AT3 XLT ?

Bought a new High Country and looking to trade out my OE tires.

I'm usually a Terra Grappler or KO2 guy...

Another tire size calculator.

The tire guy at Kalispell Costco sent me the link.

It's a software download BTW.

Aren't these a D load rating in the BFG? I wanted this size but it was only in a D load rating, I wanted to retain E rating due to weight of vehicle and towing/hauling.
