ST225/75R15 Trailer Tires

[RustyJC]

First of all, please forgive me for intruding in the TT forum, but I need to help out some friends. They have a TT that came from the factory with cheap Chinese Brand X (she didn't say) ST225/75R15D tires, and they've had 3 tire failures on one trip. I really can't tell you what they did insofar as inflation pressure, speed, load, etc. are concerned, but I told them that I'd seek the advice of the experts to find them a decent quality replacement tire. My knee-jerk reaction is, at a minimum, to move up to a Load Range E tire if their wheels are rated for the 80 PSIG pressure, but what say you about brands that have a chance of giving them better service?

Thanks for your help.

The fact that the other tire only had 15 lbs. of the recommended 70 lbs. or the spare had 30 of the recommended 70 lbs. had nothing to do with it.

They obviously were those cheap China bombs I keep hearing about.

The "deer in the headlights" look I received, when I asked when he last checked the tire air pressure was priceless.

Well there is the simple proof that tires made in a plant painted blue is not as good as a tire built in a plant painted green.

Maybe one quick method of learning the quality of your tires is to ask.
1. Does the company that made the tire put their name on the tire?
2. Can you get a 100% coverage warranty that does not expire after the first 500 Feet of use?

Nah! I just think that folks have an inflated, overblown view of the M-brand tires.

It does seem this particular forum has the most impressive Maxxis fan club. Every tire thread that comes along, it's just a matter of hours before the "M-brand fans" weigh in with the idea of it being the best.

Time and mostly mileage is.

One thing I have found to be common on RV forums is we hear folks talking about their use of a given product, and they will say things like, "I took my camper on a long trip, and this product worked well with no failures". They will define their trip in term of a few thousand miles, and call that a good test.

My feelings are, I'd rather see feedback from lots of folks over a period of tens of thousands of miles. But honestly, most RV'ers just don't use their towable that much.

When it comes to safety items like tires, "buy the best quality, toughest product you can find for the job", is my take on it.

It is actually 10 ply and 8 ply. The ten is E rated, and the 8 is D rated.

To be clear - make sure you are specifying the 10 ply Maxxis M8008 tires when purchasing. As you can see from this page, there are 8 ply and 6 ply that are the same size and also called M8008.

The issues with taking counts on forums and such is that we don't know how much of the trailer tire business each manufacturer has. If Maxxis has 75% of the business, it would stand to reason that they would have more incidents occur because more of their tires are on the road.

If we knew production data of the various brands, and then could get a count of issues, that would be a better way for us to know the percentage of failures.

Myself, I put several thousand miles on my old trailer with maxxis with zero issues. Just put a set on my new trailer and expect the same. I personally know of a set with over 80,000 on a car hauler. Trouble free. I have 100% confidence in my Maxxis STs.

MAXXIS has a proven track record on this forum. FYI, a few other off/China brands have increased the speed rating of their ST tires to 75 MPH. Now does that mean those few are better than the rest? I'll wait on the proof right here, until then, MAXXIS is it.

Switching tire type/size is technically OK as long as the new tires have a load capacity equal to or higher than the tires originally supplied on TT.

ST > LT usually requires an increase in both size and Load Range.
Using higher Load Range tires also means you need to ensure you always are running the higher inflation

On TT tires should be inflated to the pressure (max) on the tire sidewall no matter if ST or LT

I suggest you bite the bullet and get 16" wheels as that will give you a much larger selection of tires, in Brand, size and LR

I had one of my OEM Goodyear marathons blow on me, but that was after 3 return trips to southern Mexico and 2 return trips down the west coast over 3 years, so maybe I can't complain. I never exceed 60 mph and check the pressure with TPMS sensors. I am in the process of replacing all 4 with class E Carlisles. I will save a couple of the old ones as off rim spares as they are impossible to find in Mexico. I was told running LT tires on a trailer is illegal here. Not sure if it's true

[Ohio_Engineer]

I really do not understand why so many seem to believe that tires built in plants painted blue are better than tires built in plants painted Green.
That makes just about as much sense as claiming RVs built in Ohio are better than those built in Indiana. This is true because there are many times more failures of RVs built in Indiana.

Any tire from any manufacturer in any country can fail in months, weeks, days or even hours if overloaded, under-inflated or driven above their rated speed.

Increased Load Range (ply rating)is only of advantage if proper inflation is maintained. For TT this means running the tire sidewall inflation to keep tire Interply Shear forces lower and at the same time ensuring the load on the heaviest loaded tire is lower than 85% of the rated load,
