I run 55 in the front all the time and 65 when towing and 45 when empty in the rear but I run 8 ply tires so 65 is my max.

Why would you run "D" rated tires when "E" are standard?

The tire I am running is not made in an "E" in the size I'm running. The "D" That I have on the truck has the same rating as the OE.;)

So if I am correct you are running a bigger tire that has the same load carrying capacity as the E tire that is stock.

Les Schwab on the West Coast is famous for selling people D big tires and saying they have the same carrying capacity as stock. That is true but very deceiving! The D has a much weaker sidewall and is not nearly as stable of a tire.

Friends had a F350 4X4 short bed and bought a 40' toy hauler and Les Schwab sold them Big Wild Country tires and said it would be fine. I advised strongly against it, they thought I was wrong because I don't like Les Schwab for many reasons.

Well they drove to Cali and back to WA and came over to me to apologize for not listening to me. They went to LS and reamed them because the rear tires were nearly bald in 3,000 miles and was a very bouncy and a scary ride. LS bought them a new set of tires that they used when they were not towing and stuck the Michelin E tires back on when towing.

So be very careful with your tires, not safe!

Second off, how could you come on here and tell me I'm unsafe when you no nothing about my rig, weights, or anything. I don't buy my tires from Les Schwab and it don't matter where I buy them, I buy what I want not what they want to sell me. I am not running big mud cleat tires and the tires I am running we repeatedly get 60-70,000 miles out of. I will promise you this, The tires I am running have twice as much side wall stiffness as any Michelin E rated tire.Hell my lawnmower has stiffer sidewalls than a Michelin. There's a reason why the mascot for Michelin is a big Pillsbury doughboy. Because that how they build their tires, "soft".If you want a tire that gives you a great ride and get a little work out of them then buy a Michelin. I work my tires so I don't. Been there and done that on a 99 Ram that I had and won't make that mistake again , same with a gas truck.

I commented on the OP's post and get slammed for it so while I'm getting slammed you would probably like to know that I also have passenger tires on my 4500# boat that I pull behind my 40' fifth wheel @ 70-75 MPH.

So let's have it! I have big shoulders........
