Can anybody give me their opinion on what tire to run for my trailer? I have a 40' gooseneck that originally came with garbage 10 ply tires. They lasted a while, but they all decided to blowout around the same time. I put the original General tires from my F250 on it since I switched to Michelins on the truck. They have done well, until this weekend when I had a tread come apart, and after I got to my destination, found a bulge in another tire. I know these aren't the best tires in the world, but I have heard others having blowouts with top dollar tires. I know Goodyear makes a 12 ply trailer tire, but I'm not sure if I want to pay big $$$ for tires that might still blowout. No matter the quality of a tire, those trailer tires take a beating. The weight of the trailer and contents is probably around 12,500 pounds. The rims are 16 inch since I have dual 7200 pound axles, instead of triple lighter weight axles. Everybody seems to go with the 10 ply LT tires. Any opinions as far as good experiences with certain tires? Are there any tires on the market that fit this application that I do not know about? Any help would be greatly appreciated. THANKS!!!
Running truck tires on a trailer is never the best idea, because the sidewalls are designed completely differently. While it does cost big bucks, it is well worth the money to get specifically designed trailer tires for such an application, especially with the weights you are dealing with.
I'm just not very familiar who makes trailer specific tires. Most of the guys I race with use LT 10 ply truck tires on there trailers. I know Goodyear makes an ST tire, but that is all that I know of. I just assumed that everybody got cheap truck tires only because no matter what, tires were going to blow so why spend extra $$$. Texascadillac, do you know of any companies that make tires for this? Most of the trailer tires I have seen are usually only for 15 inch rims.
I run ST tires on my trailer, but they are only 8 lug 15" rims on 6k axles. Ive had good luck with the ST tires, but will look around for some others that would work.
I suggest you contact TireRack.com. They carry many items including tires specifically for trailers. If they do not have what you need they will tell you where to get it.
My Sundowner trailer has a GVWR of 11400, but I rarely carry more than 8000.
It came with Goodyear Marathon S ST tires. I just had the side wall blow out on 3 tires this weekend. They had somewhere between 10-15k miles on them and were less than two years old. Pieces of Junk IMHO. I bought 4 new ST tires from a tire dealer that carries Goodyear and he said that the Marathons gave him nothing but trouble. I bought some Duro ST DS-2100's
Size and Ply Rating O.D. S.W. Max Load P.S.I
ST225/75R15 8PR 28.8" 8.9" 2540lbs 65
that had a higher load rating and from what I could find on the net a decent reputation. I'm trailering to an endurance ride on Friday the 5th and I'll be back on the 7th with a opinion of how they handle a load on narrow mt roads
A friend of mine has a 30 ft 5-w with 16 in wheels and I was suprised to see that it came from the factory with Michelin LT 10 ply tires on it. (I think they were 235/85x16.) Check out Wal-Mart, if you have trouble they are usually just around the corner. Sam's has good prices also.
I've always had super service out of the Firestone OEM tires that I had on my '95 and '96 Pickups (put about 300,000 miles on Firestones without any problems and I could get about 70,000 miles out of a set). I would think that for your application (duels) LT tires with a load rating of at least 2200 to 2600 lbs would work.
Goodyear, Cooper, Carlisle, and Maxum plus a host of Chinese tires with various brand names on them all make ST rated tires in D and E load ratings.
For the type of trailer that you are pulling you might check with some of the commercial tire dealers around you for some of the heavier tires (G or H load rating) like you see on heavy equipment trailers hauling backhoes or Bobcats etc.
They wouldn't be cheap, but they should stay with you for a while and not run the risk of an accident caused by a blow out.
I have always had good luck with the Goodyear Marathons. I checked with my Goodyear rep (I am parts manager of A tractor trailer dealership) his answer is. Goodyear Unisteel G614 RST in A LT235/85R16 load range G with a weigh rating of 3750LBS @ 110 PSI. Goodyear made this tire to solve the RV trailer problems of running 7000LB axles.
I hope this helps solve your problem
I think that I misunderstood the original post. I thought that jj had duels on his axles. If they are single wheels forget what I said. Bordaine is correct. (Make sure your rims will hold 110 psi)
Tire load ratings for trailers are designated by letters. For a 7200 lb axle rating you are going to want a G load rated tire since your rims are 16". Typically the tire size is 235 and this makes for about 3750 lbs. capability at 110 psi max load pressure (cold) per tire assuming 2 tires per axle total.
I run a G rated Goodyear tire that seems to do very well but I also like Michelin tires on my truck or passenger car.
You should choose a tire that meets the axle rating in weight and not what you plan on carrying load wise.
I have a 40' gooseneck that originally came with garbage 10 ply tires.
You're in a totally different class than most RV applications and the experience of most on this forum. Most really heavy RV trailers use LT's for the loading capacity. ST's are primarily meant for longer life on lighter applications and are a MAJOR improvement over P-metrics (car tires). I think your best bet is to visit a few different places that specialize in truck and heavy trailer applications. They do this professionally and are set up to give you good solid experience/application based information.
I think you won't do anybetter than Michelin XPS Ribs or LTX A/S or you can look into Bridgestone V-Steel or the Toyo M-54. You will run into problems with rubber that is rated heavier than E with speed ratings. The heavier ply 16" tires can't disapate the heat fast enough heat kills tires.
You will have to look into getting custom 19.5 wheels made to cure the heat problems and tire failures. A 225/70R 19.5 will carry more than enough weight at 3640lbs per tire they have a 32" diameter. Or you go up to the next size 245/70R 19.5 they will carry 4500lbs per tire which is 9000lbs of tire capacity on each axle.
A heavier 16" tire does no good when its mounted on a rim with a weight rating lighter than the tire.
