275/60R20 for towing

[boubou]

I am not able to find a LT tire for the Dodge Ram 275/60R20
I see Michelin LTX M/S2 but that's not a E tire, still only takes 2365@44psi
there's also the Cooper Zeon LTZ which is rated at 2998 max load
These are still P tires (XL)

What are the problems with going down to 17" some people say do it, some don't

Does anyone have LT tires in that size? where to find them?

What are you towing out of curiosity?

If it's the Shasta 21FBS LE trailer, how much does it weigh?

I'm thinking a load range E might be super overkill for a 3000 - 4000 lbs trailer considering a max load of tires is distributed over more than 1 tire, and with a WD hitch it's even more distrubuted than just a weight carry hitch.

I realize the Michelin are XL P metrics but I've towed a good bit with a set and they tow incredibly well. That also was with a 7000 lb (weighed @ CAT) trailer of Father in law.

For clarification: I was towing with my FiL's truck with those tires. It was a F150 2006 5.4L XLT CC Long Bed.

Speedo will be off, and rear end will change from 3.92 or whatever your truck is to a different ratio.

I also had a super hard time finding this.

yes, it's the Shasta 21FBS LE

weight at the scales: steer axle 3320
drive axle 3460
trailer axle 5140
gross weight 11920
with WD

it added about 780 lbs on the truck so if I add 5140 and the 780 distributed to truck is : 5920 for trailer (I think I add this right ?) so round it off to 6000 lbs

If you go to a 275/65/20 you can get E rated. They're OEM to Ford Superduty w/20" wheels. A 265/70/17 is roughly the same diameter as a 275/60/20 so the speedo and gear ratio is not changed. However, going from a 20" to 17 wheel greatly reduces your unsprung weight and makes the truck feel more alive.....so I'm told

What do you mean by "feel more alive"?

I used to have a 1500 with the hemi, 20's and 3.92's and pulled a 8k TT. I too was looking to downgrade._ What I found was the 20" is almost twice as heavy as the 17" therefore taking more power to get it rolling and apparently makes a slight noticeable differance (unconfirmed). I like the looks of 20's so instead bought XL p-metric tires and changed my rear end to a 4.56. What a huge differance that made... lol!!!!!

I'm thinking about the Michelins LTX ms/2
Cooper Zeon LTZ
General grabbers XL
Bridgestones dueler A/T
BF Goodrich Rugged Terrain T/A

The difference in price does not matter, I am looking for the best all around tire. Good for towing, general all around driving and snow.

The coopers get rave reviews on the dodge ram forums. I used the Kumho STX, they were "XL" and rated around 2900lbs. I could only get them in 275/55/20. I had a 2wd and could get away with a shorter tire. There was a noticeable difference in towing compared to the Toyo Open Country I had previously.

I put 275/65/20 E rated Wrangler all terrains on our Dodge and the only issue is that they rub when turned to full stop but it's no danger to the tire... they only barley rub the sway bar in the front at the very corner on the tread so I just don't force them to rub. No other issue and we feel much more confortable with the extra ply's. Just thought we'd letcha know they fit without any real issue.
