Personally I would want a 3.73 in a SRW 6.7.

On the other hand, GM has been running a 6-speed Allison auto for a decade now in their HD trucks. I'm actually OK with a 6-speed, but like I said - it would be nice to have the short axle ratio for heavy towing in lower gears but then extra tall gears in the trans for fuel efficiency on the highway.
My only complaint about more gears is that the trucks become slower.

This is the tire I want to put on my 6.7, 3.55, 20 inch SD. This tire is 32 inches and the next would be closer to the Michelin original size of 34 inches. If I need more gear I will get the tire in the pic. If I am happy with the performance I will get the 34 inch profile of this tire.

I've got the AT/3 on my Super Duty and I really like them. Better traction than and similar noise to the GY AT/S that were on it before. I've got about 10k on them and they seem to be wearing well, but time will tell.

Thanks. I am considering purchasing separate steel wheels for winter and outfitting with a more true winter tire than the stock Michelin's. I have been using the Michelin's (AS) for 16 years in the LR E and I am fully satisfied for my normal use. I really like wearing them down over the summer when the timing is right and then replacing in November for the winter. Last set ran 65K miles and could have gone farther legally but it was time to change. Toyo has an equal or higher load rated and mileage rated tire and I also consider them for a winter tire. I am tired of having nice rims with the ill effects of winter emblazoned forever on the surface and corrosion on the bead which inevitably results in slow leaks. https://www.toyotires.com/tire/patte...k-winter-tires

You can likely find a set of take-offs with AT tires for less than new steel wheels and tires. I did the same with my F150, and get a set of new 18" take-offs from an FX4 for less than just replacement tires for my 17" XLT wheels. Then you can keep the stock look in the winter, and have nice fresh wheels the rest of the year.

Cooper is popular around my area too. A couple of comments about tread wear but that was on automobile sizes. Take those comments with a grain of salt as well due to alignment/maintenance/driver is never an issue. "It's the tires, man."

Give it two years, and perhaps the transmission will change, like it did in 2009 for the F-150 before an engine change in 2011.
On the other hand, GM has been running a 6-speed Allison auto for a decade now in their HD trucks. I'm actually OK with a 6-speed, but like I said - it would be nice to have the short axle ratio for heavy towing in lower gears but then extra tall gears in the trans for fuel efficiency on the highway.

Of course, then we're talking 2019 or later and then everyone's bringing Level 4 autonomous driving out in MY2020/21 (for the sedan world).
It would be pretty sweet to have the SD take over highway driving through TX, NM, AZ, and NV, though.
Don't mean to take the thread too far off topic with future musings, though.
