I put some on my 2022 Ram Power Wagon using the stock 17X8 rims. Mickey Thompson Baja Boss E-rated. They balanced easily and run smooth gripping the wet roads nicely. I have about 2000 miles on them with no mud or snow yet. Living in the Tampa Florida area I probably will not see snow anytime soon :)
Mounted to the rim and aired up they measure about 34.6" Installed on the truck they measure about 34". I run them at 47 PSI-fronts and 50 PSI for the rears. This image compares the original 285/70-R17 duratracs that came with the truck.

Looks great! How's your cornering and stability been on the highway/interstate?

Is this for your new XD? It was my understanding that a 17” wheel on an XD can only be steel due to caliper clearance issues.
Definitely following along as it looks like a great size.

Yep. Some aftermarket 17s like Methods fit. However, I'm not opposed to painting or powder coating the OEM steelies either. My factory Pro4x wheels I swapped my 275/70r18 snow tires on to from my previous regular Titan so I need wheels anyways for the non cold seasons.

Got some on my f350. So far, so good. Not much snow around here yet. They have the mountain/snowflake rating which is why I got them. First time in 10 years I didn't get Cooper ST Maxx.

I’d be real interested to hear how the Baja Bosses affect your mileage. I've looked at them and been interested in them, but they are a lot heavier than just about any other tire in nearby sizes. I'd love to have that size and toughness, though.

I only had the stock Duratracs for a couple of thousand miles on my 2022. I don't see much of a difference after having about 2500 miles with the 255/85R17's. Maybe a little better because they are not as wide. I did adjust the speedo so who knows if I am actually getting better milage. It is what it is!

Fit perfectly with OEM powder coated 17s. No rubbing and the spare fits fine.
