Tire Performance

Looking at changing from my stock 275/65R18 to 275/75R18 on my 2019F350. Truck is primarily used to tow my travel trailer. I am running the stock Continental tires … am considering the Cooper Discoverer AT3 XLT.
Any users made a similar change in size and can offer advise?
thanks

That would be quite a bit of difference in tire height, will really throw off the speedometer.
I would suggest a LT275/70R18, a little taller, and will only be about 2 MPH off at 75, you'd be actually going 77.
And, I have excellent performance and wear using General Grabber HTS60's, get 80K miles or better out of them.
Terrific towing tires, and give an little increase in load capacity.

Those coopers are not offered in either size you are looking for - closest is the 275/70R18 suggested above.

I have the same truck, 2019 F350 LB, also have the Cooper Discover AT3 in the 275/70-18. I have had them a few years and really like em. Good in the snow and mud and I do pull my boat which the tires handle fine, admittedly the boat isn’t a huge hurdle for the truck, 1991 Ski Sanger, all-in-all I’m happy with the tires. Also had these same tires on my 2006 F350 with no complaints.

Thanks for the feedback. I had them mounted yesterday. The look is nice … this week I’ll put them to the towing test.

I put a set of Yokohama Geolandar AT XD's on in 285/75-18. They are a true 35" tire and raised it up quite a bit. I pull a trailer as well and didn't notice any differences between stock tires and the Yokohamas. Only issue is speedo and can be fixed in forscan.

Do folks just generally put all-terrain tires on their SD's no matter what? The only time I'd be off-road in my truck would be pulling my trailer into a campground or RV resort; am I in the minority where a highway tire would actually be more appropriate?

My truck is 2WD and spec'd for towing on the highway, never off road, gravel driveways or parking lots at most at my destinations.

That DID come back to bite me after I made that decision, then tried to turn our toy hauler around in the yard/driveway one morning...the grass was still dewy and if the truck hadn't had 4WD I would have never gotten back out of the grass without making a huge mess.

Since every truck we own is also a daily driver, we put ATs on them, because we drive them year round in varying conditions - sometimes it's dry and beautiful, sometimes it's pouring rain, sometimes there's a foot of snow on the ground, but AT tires give some of the best all-around performance and have let me get to work in all kinds of weather...then go back out with my boss to pull a couple guys out of the ditch so they can get to work too.
