Buying New Trailer Tires

The family was driving back home from Oregon to Southern California and we had a blow out 24 miles north of Redding. 4 hours on the side of the road working with AAA to figure out how to get the trailer on their truck etc finally found a place that would put new tires on my trailer. NOT ONE PLACE would put LT tires on our trailer they all said they would not take on the liability an would only put on ST. My rims are only rated for 80psi. After much arguing and debate i was tired and had not so happy wife and 4yr old twin boys so i said fine and they put on 4 new Commador tires. NOT what i wanted. BUT i was able to get on the road.... Has anyone else heard of this or had problems?

Not in our part of the country. For your wheels tire dealers around here recommend the LT's. If your interested on why sent me an email at dqdick10432@yahoo.com and I'll send you an article I picked up from another forum. Don't PM me, I've never figured out how to attach something on this forum.

commodore tires if this is the one are made by michelin.

from tirerack.com "Typical passenger radial tires with flexible sidewalls can accentuate trailer sway problems. The stiffer sidewalls and higher operating pressures common with Special Trailer (ST) designated tires help reduce trailer sway."

just curious why you just didn't use your spare and have it changed on the road.... from having 2 blow outs that is what i've done? and why did you change all 4?

The problem you had with getting LT tires was probably more to do with your wheels only being rated at 80 lbs which is the pressure for LT tires to run at. Your wheels would have been at the upper end of their limits. Otherwise there is no liability on their part because many 5th wheels come with LT tires as factory. It is only when a manufactur wants to ship it out cheap you get ST tires which is why most come out with ST tires. They know the problem with those tires but the tire manufacturs won't beef them up cause it would cost more for the RV manufacturs and the RV manufacturs won't put a better tire on because the cost of the unit would have to increase. So usually higher end units come with LT tires. In 2 5ers I have never had anyone balk at putting on LT tires.

I had a flat on the same side not a blowout the day before. So the spare was on my trailer already. And since i had to replace two tires and fearing the other 2 were going to go i replaced all 4 .

I feel for you brudda! It figures that as soon as I put on the BFG commercials they offer a voluntary recall on them! We can never win can we?

Goodyear G949 tires = 80lbs. pressure and "according to a couple of Goodyear reps" ... probably a better tire than the G614. Compare the build and specs (Goodyears website) and try and figure out why one is load rated higher than the other, etc. There, that oughta get you G614 lovers going!

In all my years of RVing and going through the blow-outs and flats, no tire dealer has ever mentioned the ST tire to me. I've only used LT tires for the last 36 years. I guess I don't understand the push for the ST tire all of a sudden. I'm not even sure I'd use them on my hay wagon.

Discount tire put Michelin XPS Ribs on mine, no questions asked. I know Discount Tire has lots of stores in California. Many others have put on the same tire. I can't believe it would be a state by state policy.

This must be a Northern West Coast thing concerning on the road tire replacement. This topic has been discussed from this region on at least two other posts on the MOC in the past year. One poster couldn't get the spare put on by roadside assistance because it wasn't the same as what was on the axle. There must have been some regional lawsuit that put the "fear" in tire dealers out that way. I too have recently went with LT tires to rid myself of the Marabombs ... no questions asked.

It really must have been because your rims were only rated for 80#'s. When we bought our rig we had the dealer swap out the GY Marabombs to GY G614's that we had on the SOB rig we were trading in which only had about 1,000 miles on them. They had no issues doing this other than the cost for us of the labor to switch tires to rims and onto the new rig.

Regardless of the tire manufacturer, LT's are the way to go as the inconvienence and cost of rebuilding your trailer due to a blown tire is not worth it.

G614s ARE trailer tires even though they have the LT nomenclature. There is no tire dealer that should have a problem using G614s on any rig as long as the wheels can support them.

I am not familiar with G949s but I'm guessing that's another option to investigate. I also guess I don't care how a rating is determined, just that the tire supports it reliably and I try to treat them appropriately with proper tire maintenance and as little abuse as possible.

I've heard other stories of some tire people being religious about STs, but these are rare and a very experienced rig owner could get what they wanted or go elsewhere.
