Best tires for towing

[alex800]

I need to upgrade my tires due to some recommendation from this board. I’m towing 7500 lbs travel trailer and folks recommended that I upgrade my tires to load range D or E tires. The problem that I have is that there are not a lot of options in my tire size (275/55/20). The only tire I was able to find that is load range D rated is BF Goodrich All-Terrain TA KO2 LT275/55R20/D which is about $237 per tire from Sams Club. The other tire I’m considering is Nitto Terra Grappler AT which is XL rated that is about $190.

I need some recommendation. Should I spend additional $200 for D rated tires or will XL would be a safe choice?

I currently have Pirelli Scorpion STR with less than 2000 mi on them.

Load range is more important when there's a lot of tongue weight on your trailer. Your tires have a weight rating of 2403 pounds each. The bf Goodrich tire you've listed is rated at 2680. Not a significant difference, in my opinion.

But about about the stability? Will D tire be significantly stable vs OEM Pirelli tire? Also Terra Grappler has a weight rating if 2833 pounds but has XL rating.

A 55 series sidewall isn't going to be too squishy. I would personally give it a try and then decide, if time allows.

Do you mean give it a shot to Pirelli?

If I remember correctly in your other thread you're trying to mitigate sway caused by a new TT? Make sure your weight distribution is set up correctly first, this being determined by suspension squat and load leveling more than perception of sway when going down the road. Also look into the anti-sway (usually friction based) system that can be purchased with or added onto a current WD hitch. Are you running your current tires properly inflated? What pressure? What is their max? Personally, when towing anything with a decent tongue weight I max out my tire pressure regardless, makes a HUGE difference!

I already have Equal-i-zer Hitch and it is 95% percent setup. I still need to go to weight it just to make everythink is OK.

My current tires are Pirelli Scorpion STR. Last time I was towing I inflated them to 40 psi. I think the maximum is 44 psi.

Yes, i would run the pirelli tires and see how they do. Run them near max inflation (since max load is calculated at max inflation). If you're experiencing sway, then tires won't fix that. I've never used a weight distributing hitch, so i can't speak to that. But i do a lot of trailering. Too much tongue weight will make the front of the truck too light, and hard to drive. Too little tongue weight (or too much weight at the back of a trailer) will cause it to sway at higher speeds.

Broke the bank yesterday and installed new KO2 tires....
