The Goodyear Marathon tire gremlin hit me!

[Motorhead]

I just got back from a 3,000 mile round trip to Yellowstone ... . Less TWO Goodyear Marathon tires! I had two blow-outs, one in Idaho and one on I-5 about 120 miles from home. The tires had only less than 10,000 miles on them. Yes, they are 6 years old but come-on... these things should last better than this. I had to buy a new tire in Idaho so I had a spare. I looked at the new "D" rated tire the next day and it was made in CHINA!!!
I ran them at 49psi. They were rated for 50 psi.
It is really sad that an OLD AMERICAN tire company is selling me tires made in CHINA! They have lost ANY future business with me!

Motorhead try firestone tires teansforce HT . I had the same goodyear tires all 4 was gone by 4000miles Had to fix the trailor 2 times. I talked to Roger Penskie. They use this tire on ther rental trucks and trailors. The st trailor tires is rated to only 65mph the truck tires have a better rating ---GOOD LUCK

Motorhead: You may have your tires underinflated. From the Goodyear site:


·

Industry standards dictate that tires with the ST designation are speed restricted to 65 MPH under normal

inflation and load conditions unless a different speed restriction is indicated on the sidewall of the tire.
·​

​

Based on industry standards, if tires with the ST designation are used at speeds between 66 and 75 mph, it is

necessary to increase the cold inflation pressures by 10 psi above the recommended pressure for the load.
o ​

​

Do not exceed the maximum pressure for the wheel.

o ​

​

If the maximum pressure for the wheel prohibits the increase of air pressure, then the

maximum speed must be restricted to 65 mph.
o ​

​

The cold inflation pressure must not exceed 10 psi beyond the inflation specified for the
maximum load of the tire.


I tow dozens of different trailers every year. Most all have the tires underinflated. I usually inflate them to 10psi over the sidewall max (if it's a ST tire) and rarely have problems.

Were both blown on the same side? I think when one goes, the other takes all the weight very quickly, damaging it. That's what happened to my POS Carlisles.

I just saw a gadget on one of the science channels that screws to the top of the valve stem like a cap... . you carry a hand held device and touch the head of this cap... . it reads the tire pressure for you... . and for what is suggested several hundred less than the TPMS currently available.....

Since most tire failures are from low pressure... mind you, you still have to walk around and touch the tool to the stem... . but the cap is an air tight seal... . this might be the answer... at a much lower price... . I wasn't listening enough to get the brand name or other information... .

If someone has heard of the same product would you post the information...

I really don't think much of the Goodyear Marathon tires. The failure rate seems pretty high. But it may not necessarily be the fault of the tire. They used to be the industry standard, and many new trailers came with them. Most trailer manufactures use the cheapest tires they think they can get by with and still carry the weight of the trailer. Many times there isn't much margin between the load the tires can carry and the weight of the trailer. Most people without realizing it overload their trailer, underinflate their tires, and drive too fast. All of these things increase the heat produced and contribute to tire failure. To determine proper inflation for your tire you need to weigh the trailer after loading and go to the tire company's spec for your particular tire and the weight they will be carrying. You may very well find out that your tires are not designed to be carrying the weight you are putting on them.



You can go up a load range, but if you do you need to make sure that the wheels you are mounting the tires on are able to carry the extra weight. I've seen wheels develop a crack from being overloaded. Usually this will cause loss of air or a flat, but it could become more serious if the wheel comes apart at highway speeds.

I've been blessed to have never had tire trouble in the twenty-seven years I've towed trailers or hauled a PU camper. May my good fortune continue! That being said, I keep an eagle eye on my six trailer tires. I use the old-school kick the tires with my heel and feel/listen for the different sound of lower inflation.



Something I've noticed for many years-- a large percentage of the trailers I see on the road seem to have awfully small tires for such large units. Very few of the larger units I see have triple axles and to top it off, they have very small sized tires. Granted, I have only owned two trailers, both Airstreams, so I have very limited personal experience. That being said, how close to the maximum weight was your load? The units I spoke of above have to be very near, if not over, the maximum load ratings for the tires.

Motorhead, count yourself fortunate. I lost 4 out of 6 of my Carlile's on a 400 mi. trip to Pismo. They didn't blow out on the road, but when I stopped to check-in all 3 on one side and one on the other were ballooned up to about 25% larger than normal. This was with only 4K mi. on them. I was glad to fork over an additional $750 for that trip. #@$%!



Of course, the road hazard warrantee didn't cover.

Oops.



According to this, for the speed I was traveling I guess I should have over-inflated them 30-40 lbs. ​

On my other forum ( TheMalibuCrew.com ) seem that these tire fail all the time on their boat trailers. Seems that all that failed were traveling faster then 65mph.
