Trailer Tires

[itsrusty2]

Has any one replaced their trailer tires with Car tires? Is it possible. I keep wearing out the trailer tires

Re: Trailer Tires

Do you get uneven wear on the trailer tires so that you have to replace them, or does the tread wear evenly, but fast? You could have a misalignment in the axle placement, or a bent axle. Car tires have weaker sidewalls, and don't give as good control as the TS tires. That said, a lot of people have used car tires, or better, LT tires on their trailers. It's your choice, I have always chosen the TS tires for the better control and safety I get.

Re: Trailer Tires

Better to use trailer tires on a trailer since they have heavier sidewalls, higher air pressure, heavier load ratings.

Re: Trailer Tires

Consider larger diameter trailer tires.
Less revolutions per mile.

Re: Trailer Tires

Would need more information regarding trailer to figure out what is causing the tires to wear out. Pictures would be a big ++++

It's possible but not smart. Radial trailer tires are well worth their money. They wear much longer and more evenly. Passenger tires are dangerous on a trailer, LT not much better.

Re: Trailer Tires

They shouldn't wear out to soon if you keep the tire pressure to where it's supposed to be unless to have a bent axe.

Correct.

Re: Trailer Tires

Pic of worn tires would help. If you have a wear problem, there is no reason to believe car tires would last any longer.

Re: Trailer Tires

My trailer came from the factory with car tires. Reviewing their catalog it showed that for each frame size, they marketed 4 different load ratings. The smaller 2 were equipped with bias ply auto tires, and the 2 with the heavier ratings were ST tires.

LIke everybody else said, explain the problem.

You may find it interesting that the NHTSA doesn?t agree with that philosophy when the tires are sized according to specification.

Part 571.120: Tire selection and rims and motor home/recreation vehicle trailer load carrying capacity information for motor vehicles with a GVWR of more than 4,536 kilograms (10,000 pounds).

S5. Requirements.

S5.1 Tire and rim selection.

S5.1.2 Except in the case of a vehicle which has a speed attainable in 3.2 kilometers of 80 kilometers per hour or less, the sum of the maximum load ratings of the tires fitted to an axle shall be not less than the gross axle weight rating (GAWR) of the axle system as specified on the vehicle?s certification label required by 49 CFR part 567. Except in the case of a vehicle which has a speed attainable in 2 miles of 50 mph or less, the sum of the maximum load ratings of the tires fitted to an axle shall be not less than the gross axle weight rating (GAWR) of the axle system as specified on the vehicle?s certification label required by 49 CFR part if the certification label shows more than one GAWR for the axle system, the sum shall be not less than the GAWR corresponding to the size designation of the tires fitted to the axle. If the size designation of the tires fitted to the axle does not appear on the certification label, the sum shall be not less than the lowest GAWR appearing on the label. When a passenger car tire is installed on a multipurpose passenger vehicle, truck, bus, or trailer, the tire?s load rating shall be reduced by dividing by 1.10 before calculating the sum (i.e., the sum of the load ratings of the tires on each axle, when the tires? load carrying capacity at the recommended tire cold inflation pressure is reduced by dividing by 1.10, must be appropriate for the GAWR).

I wonder why the tire manufacturers bother making special tires just for trailers?

I guess it could be because they just work better!

Since trailer (ST) tires reduce sway and rolling resistance, why would anyone use something else on a trailer? Something not designed for trailer use? If there's no difference, why not use trailer tires on a car?

There's no point in trying to re-engineer this stuff.

Exactly! By NHTA standards you technically could put a drive axle tire on the steer axle of a semi tractor. BUT YOU DON'T. You could put mud terrains on your trailer by that logic. BUT YOU DON'T. Why? Because it's not engineered to do that. Who had any reason to invent trailer tires in the first place if passenger tires worked fine? This shouldn't be that hard guys.

Re: Trailer Tires

use the right tool for the job. that is why there are so many different tires. the tire companies do a lot of r&d. If they did not do this you would have what happened a few years back with the
wrangler tires on the fords. blowing out and killing people.

Re: Trailer Tires

BTW: If the sidewall of the trailer tire says maximum pressure 50 PSI, inflate it to 50 PSI (when it's cold). Don't think about it, don't try to justify something different, follow the instructions. 50 PSI.
