Goodyear Marathon tires

[poloace]

I just purchased a montana 285rld two months ago, and am still on the road.
I have heard from other 5th wheel owners, that the Goodyear monarch are junk.
Anyone else have proble, s with these tires?
People tell me to get rid of them as fast as I can.

LOL. Really based on your opinion or have you actually used them.

Both...When I say, "I happen to think" it means that is my opinion. My opinion is based on many years of my experience. All used with very good maintenance. And yes, I have used USA Marathons, and Chinese Marathons. On my 5'rs, and also on cargo trailers. The USA tires were better. But the Chinese marathons, have had serious issues. None went more than 3 years without blowouts on several. Most gone within two years. The others were replaced, before they could cause more damage to my trailers. I have had problems with any Chinese ST tire, I have used. Then I finally wised up, and gave up on Chinese tires. Haven't had tire problems since. My choice is LT tires made in USA or Canada.

Point taken, I've had the opposite experience. Almost 10,000 miles in 2.5 yrs on my last set which were USA. Still had 30-40% tread left. Moved into a 5'er that has Chinathons on it. Based on my experience I will run the Chinathons till I need new tires. Probably upgrade to 16" at that point since that will allow me to run faster than 65 mph we conditions warrant.

Just wondering how close you were on load capacity. My last set were running at 64% of capacity and the current set are at 70%.

Anyway... I found this Marathon Inflation PSB

I've been running them at 90psi and so far we've put nearly 2000 miles on 6 separate trips in 100+ degree Texas heat without any problems.

Fingers crossed.

I don't think the PSB says OK to exceed max sidewall cold inflation pressure.
It would appear to say if your tire placard(gvwr sticker) says 65psi you can go 75psi however I think that assumes your sidewall says 80psi max.

The PSB doesn't mention 65psi or 75psi or 80psi at all.... or any specific PSI at all for that matter. Nor does it mention a trailer's placard at all either.

Actually it simply says if you travel at over the standard 65mph speed limit, increase the pressure by 10psi. And "The cold inflation pressure must not exceed 10 psi (69 kPa) beyond the inflation specified for the maximum load of the tire".

We bought our used 2009 Keystone Challenger 34SAQ in April this year. On our first trip we had a blowout. Those tires were OEM and built in 2008.

I bought a new set with build date Dec 2012 - So far that hasn't been an omen LOL!!

Unfortunately almost all of the products have we have available to us as far as electronics and other items that are commonly found in RVs from tires to light bulbs are made in Communist China. We are just going to have to learn to deal with it

The newest Marathons are made at a new plant with direct GY employees to QC the manufacturing and materials.
Previously China Marathons were just build to spec. Primary specification must have been low price :R

My opinion based on my experience and watching others is that most tire failures are human failures in regards to care and maintenance. Tires are tires, maintain them and do not exceed their speed or capacity.

If you are leery about Chinese made stuff, rip out all of your electronics immediately. We vote with our wallets and we have voted for China and India.

Just curious how you account for the several posts on here about spare tires blowing up while they aren't even mounted on an axle...I think the Chinese are capable of making a good product, but the manufacturers are more interested in a cheap price. When it comes to cheap nobody is better at it than the Chinese.

I beg to differ with you on the cause of ST tire failures. You state that you believe human failure is the biggest contributor. Why is it that there are hundreds of thousands more P tires on cars and you see a fraction of the failures that you see on ST tires on trailers?
Do you really think that the general population is more prudent about taking care of their tires on their cars?-I highly doubt it. I would bet that 30-40% of the cars going down the highway have tires that are under inflated and yet you see very LITTLE tire failure.
It all comes down to the ST tires are NOT held to the same DOT specifications as P and LT tires.
