Trailer Tire Ratings

#1 Post by John_Heard » Wed Feb 21, 2007 10:16 am

I've currently got 15" load range "C" tires on my 24' Pace trailer. It's GVWR is 7000# with two 3500# axles. I know the tires according to the specs are rated for this use but how about in real life? I didn't have any problems last year, was very careful to watch pressures also. Was I just lucky?

I hear of a lot of other guys having problems with the 15" tires (TYDO Mark comes to mind!) and have been thinking that maybe I ought to get some higher load range tires? Right now getting ready to buy two extra rims and tires for spares. Any thoughts? Would it be a better idea to get 16" rims all around now before I go out and buy some spares?

This is just from pure experience but at the dealership on our pull trucks we use nothing but 10 ply radial 16" tires like a Firestone TransForce or a BFG Commercial T/A. Before we switched to these we were always having blowouts and low tire life. We rarely have a bad tire now and the tires last alot longer.

I remembered why I didn't do this last year - tire clearance with the inner fenderwell at the top. I already have rub marks there with the 205's, going to the 225/15's is going to make that worse. Problem is I don't think anyone makes more than load range C in a 205?

Does anyone make a 16" 5 hole 4 1/2" bolt pattern trailer rim?

Carlisle makes a 8ply radial in a 205/75/15 if that is not to tall.I think the MFG# is 5198081. I don't see anything in a 10ply in a 205/70 or 75.

I've had a lot of trouble out of the C rated 205/75-15s. I popped three of them last year as I recall. So I've moved up to D rated 225s. No rubs that I've noticed on my Haulmark.

Craig what brand did you use? You have any idea what your trailer weighs loaded/empty?

They were a mix of brands. One was a Goodyear, one was some off-brand that I picked up in Western Oklahoma on the way home from G05 and the other might have been a Kelly-Springfield (not sure). The Goodyear faired the best. I saw the broken belt before it blew. The other two just went without warning.

My trailer is rated at 7000#. I guess I'm exceeding that. The car is 3100 at full weight, 366 lb 4-wheeler, cabinets, generator, tools, observation deck top, 20ft awning, etc. I think the trailer itself is about 3300.

Another problem is speed. --builds heat
Luckily I knew about the tire troubles before I bought my trailer, and got the 8000 lb axles and 16" wheels. I had friends blowing out a tire or 2 per trip. Did not matter if they where new or not.

I think all my blowouts have happened at about 55-60 mph.

Talked to the local tire shop and they recommended Denman tires for the trailer. They make a 205/75R15 in a 8 ply. He said he's got several people running them hauling skid steer's around on 2 axles trailers and it's the only tire they could get to hold together on them. They also make a 10 ply in a ST225/75R15 but they're 28.5" dia.

Good info. Denman...I'll have to remember that in case the 225s ever end up giving me trouble.

Nobody can stress enough about how important it is to have your tow vehicles and trailers in perfect working condition.My wife was towing 2 of our horses yesterday and had a tire blow out and I mean BLOWOUT no sidewall left at all,luckily she wasnt on the highway and was only going about 35.Not only do I have to buy a new tire but had to leave work for an hour and a half to go change it.Think about how bad this could have been.Just a little routine maintanence I could have avoided this.We all spend tons of $$$ on our race cars and in my case my horses too and then seem to look for a deal on tires or the trailer itself.The fact that tow rigs need to be way more reliable than the car itself is something everybody need to realize.

In my case, 2 blowouts were on practically brand new tires and one I caught before it happened because I was keeping a close eye on the tires.

On my winter projects list is to inspect and pack the trailer wheel bearings, inspect the brakes and re-line as necessary, new brakes on the front of the truck and give everything a good look.

Can't be too careful, that's for sure.

You looked at my list. I have a 24' Pace also, and so far no problems with tires. It will be getting new rubber very shortly though. It was a 2002 leftover that I bought in 2003 and still has the same rubber on it. I think it's time.

How often should you check bearings on those trailers I wonder?
