View Full Version : My First Blowout

On an RV excursion covering 9 states and 7 weeks, we just had our first China Bomb disaster. We were fortunate to get 25K miles and 8 years on the China Bombs. We pulled into a rest stop on Hwy 97, north of Madras, Oregon about 30 miles. Virtually out in the middle of nowhere. I always make a habit of walking around the rig, looking for problems. This time I was not disappointed. I had a flat tire. After spending an hour changing the tire, we found a seven inch gash where the tread had separated from the sidewall. Thank God we were not driving at the time. At least in a parking lot we had room and time to change it.

When we got to Boardman, OR, we inquired where we could buy tires. A Les Schwab was just down the road in Hermiston. We called and made an appt for the next day to install four new tires.

Now I have some peace of mind that the next 3500 miles should be tire free.

And you replaced them with?

Eight years is longer than you should expect trailer tires to last anyway. You really got your money's worth out of those.

With your good luck you should buy a lottery ticket!

Age of the tires, not miles is the factor that needs to be considered. With our original GY marathons, we got better than 30,000 miles in the first 2+ years but they were on their last legs when replaced w/ five Sailuns. Even with the Sailuns, I won't go over 3-4 years.

Eight years?!?! I don't know if you can say the tires failed because they were "China bombs" or just old. My guess is age had a lot to do with it. You really got your money's worth out of them. It is good to hear they failed while you were stopped and not driving down some highway at 60mph.

Eight years, that's got to be some kind of record!

I'm glad I joined this site and read this post. We have an 08 319bh with the original tires. We have never used the camper that much and the tires look fine.

After reading this I will definitely put new tires on it!

We are actually thinking of taking or first trip out of the state, meeting up somewhere with relatives headed up from Louisiana.

Thanks all!

Before joining the MOC I never considered replacing tires based on age instead of wear factors. I learned from some of the old timers here and have never experienced a blow out. We travel around 4,000 miles each summer and generally while out west during the summer will start seeing RV's pulled over with blow outs.

Our 2014 gas MH only has 12,000 miles on it now after this summer vacation. However, if we don't trade the tires are getting replaced because they will be over 4 years old this next spring. It will cost between $2,400 and $3,000 to replace all six but there is no way I am trusting these tires while traveling next year. The coach is in hot temperatures all year long and it takes it's toll.

Wow! 8 years is old for any brand, any tire. I keep mine shaded and treated with 303 Protectant, but they come off at 6 years old. Always. Without fail. I've never once in my RVing history had a failure. A few nails but never a failure.

Has anyone heard of or have an opinion on the new Goodyear Endurance tire for trailers and RVs? Made in US, said to run cooler.

My nephew, works in the shop, did a lot of research on them and bought a set for his SOB camper. From what he found they are somewhere between a Marathon and a G rated tire. Would probably, probably be OK on a fiver somewhat lighter than a Montana. Just my opinion. For a big Montana I'd stick with a known G rated tire.

You can pay more to test Endurance for GY OR get Sailun S637 (a G rated tire) for less. In about 5 years we will know how good Endurance is, but an E rated tire should not be on a heavy 5er. Do a search for Sailun failures and IF (unlikely) you find one please share.

OK, Sailun S637 it will be. I was getting a tread wear rebate on the GY tires but it seems to be overwhelming recommendation to go with the Sailuns. Now hopefully my RV dealer can get them through his distributor.
Thanks all.

Smart move. Worry no more.

So is the Sailun S637 a G rated tire or do I have to specify a G rated version of the Sailun S637?

I think it's G rated if not someone will correct me.

It is G rated 14 ply.

"G" easily seen on my Sailun 235/85/R16 ~~

I did find the Sailun S637 locally. Do trailer tires need to be balanced?

I think so. These campers aren't very well built and the extra vibrations from an unbalanced tire isn't good for then and certainly isn't good for the suspension.

I agree, they sure don't come balanced from the factory as far as I know

There has also been a lot of discussion about balancing trailer tires. One of the things discussed has been regular balancing and lug centric balancing. From what I've experienced, with the machined aluminum wheels, standard balancing works just fine, as the lug holes are perfectly aligned with the center hole of the wheel. With steel wheels, on trailers, the center hole in the wheel is not machined and normally is not centered on the lug holes, so the wheel must be balanced by the lug centric method, which uses an attachment on the balancing machine to hold the wheel by the lug holes instead of the center hole of the wheel. I do find the tires do hold up better having the tires balanced, and do not have irregular wear issues. As far as better ride, who can tell with the roads as bad as they are.

I have seen many of trailers with tires much older than our 5 yr replacement oath. Many of equipment trailers hauling 15K backhoes or landscape, snowmobile and tractor trailer tires.
I have also had my share of blowouts. Travel trailers past as well as 5ers. Tent trailers never seem to have a problem unless it is a blowout.
Think of how many trailers you see on the road.
Yes I have seen TT carcass scattered along the road. I always attributed them to retread's.

I just don't understand why we have such difficulty. I had a leak at an overnight in NJ. The tire guy I talked to said inflate only to the required combined Load. His explanation was (he had a motor home) there is no flex in the tread or sidewall keeping the 80 psi if it is not required by the weight of the unit.

Another friend said if you put flour on the ground and pull the tires over it and measure the square inches occupied by the tire foot print. He could determine the weight of a 4 tire set within 400 Lbs reliably on the ground. It is pounds per square inch and he made sense. Old school or not. Just have to be careful how far go to get a good impression.

Maybe if there were 3 axles and less load/tire it would be better, Just much more expensive if we keep the 5yr replacement. I bought savaro 3.5K lbs tires for the truck twice, Tread wore way to fast but they were only $120 mounted and balanced. Not good steering tires on a dually. Yoko's were a 3 yr tire at least. Never tried Mich or BFG commercial.
