Violent tire blow out messed up my rig

[Octaneforce]

I have a 1993 30ft class a fleetwood coronado on a p30 chassis. Im super on top of maintenance and safety but on the way back from my last trip a rear inner tire blew out and mangled the under storage cabinets. It literally blew the doors clean off. I managed to get them back in place and limped home on 1 tire. all 6 tires were replaced about 7 months ago and only have maybe 2000 miles on them with nice even wear. They are samson 8r19.5. Definitely a cheaper tire. After closely inpecting these tires i noticed that every single one of them has small stress cracks on the sidewalls. Why are these tires failing already? Should i replace the blown out tire with another cheap samson? Id really like a new set of goodyears all around after this experience but these tires are so fresh still! Minus the stress cracks. I was running 90psi all around. The sidewall calls for 110psi which seemed high to me. What tires do you guys run? Are crazy blowouts like this common?

I do have extenders on the rear inners. However they were replaced and checked for leaks not too long before the tire blew out. How else would i be able to adjust the tire pressure of the inner tire without an extender?

Many users say, "buy a quality tire". Well exactly what is that? Many have had good luck with Samson, Hankook, Toyo, Hercules, and many have had bad results with Michelin, Goodyear. I had less than 5 year old Goodyear G670's and had 2, TWO! blowouts on the same day. Goodyear refunded my money on all 6 after some complaining to the state attorney general's office. Sometimes all you can do is have a TPMS, keep an eye on them for cracks, keep properly air inflation to the weight of the rig, and continue to play this game of what appears at times to be 'Russian roulette' when it comes to tires.

So after many weeks of very good communication, samson is sending me a check to cover 6 new tires and the repair to my baggage doors. I was really impressed with the customer service and they were incredibly understanding. I thought they were going to send me actual tires but they kind of just left it up to me to decide if i will use samsons again. The shop i want to use doesnt even sell samson. They want to sell me sumihotos. I feel a little guilty but it is what it is.

6 new sumihoto tires mounted and balanced with “sandbags” along with an alignment, and i was quoted at roughly 2000 from my shop of choice. I priced around a few other places and they are all about the same. The chinese tires are definitely alot cheaper but i dont want to take a chance with my family riding in the rv! Lol

Good deal! Glad it was resolved to your satisfaction!!

I sent an email over to samson and gave them the situation. We’ll see what happens!

I've used Toyos on all the vehicles I've owned in the last 45 years, once the originals were replaced. These include both a Class C and a Class A. I've never had a failure. Three different failures happened with the tires supplied on the new vehicles at relatively low mileages.

Hope you kept the carcass of the tire. If so, then call Samson and start a claim/investigation for a defective tire. I had the same happen to me on a brand new Goodyear G647 (date code less than 4 months old at the time). Although Goodyear did not formally say that the tire was bad, they DID reimburse my insurance company for the tire as well as the damages incurred by the blowout. The tread on the tire peeled off. It looked like there was rust on the wires under where the tread peeled off. And yeah, it will cause chaos to the coach itself!

I lived in So Cal where there is a high ozone content. 4 yr old Michelin's on my 3/4 ton PU looked worse than those Samson's! Michelin wouldn't even return my calls or e-mails.

Have you contacted the manufacturer? 3 yr old tires shouldn't be having issues already.

[Octaneforce]

I guess these sat on the shelf for a while. Now i dont trust these tires. Is it worth switching to the metric size if i do all 6? Or just get the same size it has now? I might try the sumihotos. At the very least i need to get 2 new fronts like one member said and throw an old front on the rear.

Okay the inside of the tire says 3915. So these tires are more like 3 years old. Damnit.
