This might be an old issue, but I am new here.

I had a blow out and the tire manurfacture will not cover the tire.  I went to just buy a new tire and the tire dealer told me I needed to install a higher rated tire on this trailer, but he would not install the tires on the wheel that I have.  He told me the rating of the tires and wheels did not match and I would still have troubles down the road.

What I have on the trailer now is a 16" G rated tire that shows 3500lbs. at 94psi and the steel wheels are 16" 8 lug that show a max rating of 370lbs. at 80psi!  The tire dealer is telling me that the psi of the wheel should meet or exceed that of the tire!

WHAT DO I DO?

What kind of trailer are you pulling? What's the GVWR of your trailer?  GAWR? What's your trailer weigh? How fast are you pulling in this heat? Are you running 235/85R16's? OR 17.5's

Sounds to me that....You need a set rims rated at 3800# at 110 psi for the "G" rated/14 ply tires. 100 psi will give you a 3750# rating on the G614. The rim needs to be rated higher than the tire.

I just looked at the link you posted and I think that is the tires this tire dealer in wanting to install, but what about the wheels?  The info on the wheel shows a rating of 3750 lbs. but the psi is only 80#.

This is the problem I guess, the dealer is telling me that if I install these tires and put a 100 or 110 psi in them that there is a chance the wheel would come apart!

BINGO!! You're going to have to get the heavier/high pressure wheels..... Move up to 17.5 with a rating of 4800# per wheel.... Or lighten your load. With 15K sitting on the axles alone.. I would be looking for some 17.5. You're not just carrying all that weight, your twisting on those tire sidewalls, like you're wringing out a towel!!

What axles your axles rated at? 7000#, 8000#, 10000#, each.

I have 7000lbs axles on this trailer, that is what came on the trailer.

I missed one of your questions, I pull this trailer at 65 or just under on the interstate and in town and back road usually 5 miles under the posted limit because of the weight and the amount of time it takes to stop this thing you never know what retard maybe coming out of a driveway or around the corner.

Thanks, c.will 

If you truely have 15k on the axles. then the two 7000 lb axles egual 14,000 and are not sufficient for your load. And four "G" tires barely make the 15,000lb. And they do need to be mounted on rims rated for 110psi.

You tire dealer is telling you the truth, you need to upgrade Tires, Wheels, and probably axles.

Have you actually weighed the trailer to see exactly how much it weighs when loaded with horses and all the stuff you haul?

So many people buy a trailer shell with axles that match the trailer, Then they add a LQ and they are way over weight.

If your trailer really grosses out close to 20,000lbs, and you add ( I suspect a dually pickup) at around 9000lbs. You probably are over the 26,000lbs that usually requires a CDL license to drive. You will have to review your own state laws on that.

Yes, I have taken this trailer over the CAT scales and I had the tire dealer check it also and the gross weight is right at 19-k lbs. and the actual axle weight the time I checked it with 2 of my large horses and 2 of my avg. horses was 14,660lbs, but this was loaded with everything but the black and grey water tanks full.  The empty or (dry) gross weight is 12,740lbs.

I haul with a 07 Dodge cab -n chassis quad cab with CM hauler bed, 6.7 diesel, auto, factory exhaust brake (HELPS A TON with this load) and you are right we hit the scale loaded right at 25-k lbs loaded!

I just check our other trailer we just bought for vet trips ( 07 S&H 3 horse gooseneck with 2'SW and it has ST235X85R16's and the rating on them shows E 3640lbs at 80psi and the wheels show 3750lbs at 80psi.

Would these tires work on my larger trailer since the psi rating is the same.

Sorry so many stupid questions, just don't have the money to do the 17.5" tires and wheel or even 16" tires and wheels both right now.  Everything I am reading and seeing is telling me the same! (tires and wheels must match lbs. and psi, or wheel must exceed the tire rating)

I guess if I am reading the replies correctly, the rated psi and weight of the wheels should be the same as or more than the tires themself?

Can anyone give me any idea on where I can find wheels to work with heavier tires without having to buy 17.5"?  We are planing a trip for the end of the month and want to get this done before we leave.

Also, will it hurt anything hauling at or over the trailers max weight? 

 don't know which brand of tire you have, Maybe I read past it. But using the Goodyear specs.

I believe I read that you currently have 235/85R/16 "G rated" tires, according to Goodyear that size can handle 3042lbs at 80 psi.  (which is what your current 80 psi wheels will support)

That same tire will support 3750 at 110 psi.  So if you keep your same tires and just upgrade your wheels. you will gain 2832lbs of Load carrying.

Your dealer is being safe by not mounting "G" tires on a 80 psi rim.  Most folks look at the tire and inflate to what ever pressure the is stamped on the rubber of the sidwall.  Few people actually look at the rim. So with a "G" rated tire on a 80 psi rim, too great of a risk of somebody over inflating it because they didn't look at both the tire and rim.

Four "G" rated tires and rims will give you a 15,000lb load limit. But you say your axles are only rated for 14,000lbs. ( two 7,000 axles) So now you have overloaded your axles.  All parts are over engineered. So will your axles support 14,001 lbs or will they support 18,000lbs. I don't know where the weak link will be in your setup. Will the lug bolts break, will the torison bars that support the axles break, will the bearings give out. Something in each of your axle is only designed to support 7000lbs. so possible that part will give out when put under stress. Apparrently they have held up to the 15,000 so far with only a tire blow out.  But at some point a part will fail. I'd hate to see the lug nuts pop off at 65 mph on the freeway.

I think the cheap fix right now, is to get the proper rims and run your current "G" rated tires at their maximum pressure. The proper and long term fix will be to upgrade your axles, tires and wheels.  My friend just ordered a new trailer. It's heavy like yours so he got it with 3 axles all sporting "G" rated tires.  6 tires @ 3750=22,500lbs total.

Over-weight?...YES

17.5 wheels with 9/16" stud holes....  http://www.trailertiresandwheels.com/site/1284278/product/0377865

OMG!  I did not realize that there was so much involved in tires.  I thought if you had a 16" wheel you could put any 16" tire on it.  Guess I was wrong.

THe tires that are on my trailer are called Winland and they show 14 ply rating, 3500lbs at 94psi.  I just got back from another tire dealer and was told that these tires are a poly belt instead of a steel belt.  Now what does that mean to me????

So if I install better tires and wheels will I still be able to haul the weight or not?  Or do I need to look into larger axles too?

Chinese tires...

Don Dominguez, longtime head of the former Private Brand Tire Group, has completed an agreement with a Chinese importer to introduce a private brand tire line to the U.S.

Mr. Dominguez, formerly a consultant to Mitas Inc., told Tire Business that Winland-brand medium truck tires will ship...from China.

Ye reap what ye sow..... I would stay away from these "private brand" tires. The side wall should read if they are poly belted or steel belted ...My guess is poly.

I will call them on Tuesday, they are only about 30 miles from me.

This trailer is just over 1 year old!  I bought it to haul 4 horses with every weekend, but since the tire and wheels issue we either haul just 2 or 3 horse and beg someone to pick up the other horse if the family goes.  Now we have bought a 3 horse S&H gooseneck and parked the LQ until we can figure out something on the tires.  My better half and daughter are the ones that use the LQ trailer most of the time, they are into these competitive trail challenge deals around Texas and my job is to make sure they have something to use that is safe and dependable to use in case I do not get to go with them to fix any problems that may happen.  The blow out that happened, I was not with them and they said that it felt like the trailer actually came off the ground.  They was heading out 281 through Stephenville going to Blanco for a trail challenge, lucky for me some folks stop to help them and saved me a 2 hour trip to change a tire.

We are checking into US RIDER right now, but I don't think that is going to help the tire and wheel probelm at hand.  That is what I am needing help with 1st.

Thanks for all the help.  If anyone has any other ideas, PLEASE let me know.

Is there a way to reduce the load on the trailer?

At a minimum you need new tires - then it's a matter of staying under the 14,000 pounds the axles, wheels and tires are rated for.

I am curious as to the trailer manufacturer and if you bought this used because I'm wondering if a previous owner put the chinese tires on, or if they were original equipment. I would not be surprized at a mfgr using small axles, per se... but I would like to know which one it is.

thanks.  This thread made me go check my data plate for my trailer - I've got 6k axles on a 3H steel GN with GVWR of 10,180. Trailer was 5300 empty when new, I've added about 500# in insulation, paneling, etc. I only haul 1 or 2, 1000 pound horses. Even if I did 3 horses - it would be without camping gear (water tank & hay) so I'd still be okay.
