Blown tire

rvcycleguy · 07-11-2016, 08:33 PM

For those of you who haven't had a left side tire blow... It may not be if bit when... Mine went yesterday. Took the fender skirt, all sewer plumbing that was exposed below the belly of the TM. Gray tank piping, toilet plumbing that's below the trailer. Found most of the plumbing while walking the debris trail 1/4 mile back from where I stopped. Was able to get the spare tire on and then take it slow to a tire shop to get 2 more and then place the right side tire as a spare.

Piecing it together now with the assistance of an RV dealer nearby my home. Gate waste valves, 1-1/2 inch piping, 3 inch piping, intermediate piping with the cap end, etc, etc. Not sure the damage yet to the gray tank or the dump pipe from the toilet. Sheared off pretty good so I may be able to use rubber hose with steel clamps to amount it all back together. Hopefully it didn't rupture the tank.

Ray..if you get the Sealand toilet they give you a free gate valve and most of the plumbing you'll need to do the repair...I didn't mention this earlier to you. And to everyone else...if you don't have some kind of blowout cage to protect your plumbing (or worse, like the whole of the cabinet in the bathroom), then your skating on thin ice...your call everyone....

I'm truly sorry to hear this. It has happened to a lot of us, including me, and it is tough to recover. Were you running Goodyear Marathons? Or had you installed another brand? Were your tires the OEM 14" tire size, or had you upgraded to 15" tires?

There are as number of threads about fabbing and mounting a cage to protect the plumbing. I haven't done it yet, but maybe now is the time.

It would be really nice if there was a kit available to protect the plumbing. I bet one could be made that would fit most Trailmanors. I was lucky my blowout was on the curb side. Seems like blowouts are not a question of if you will have one but more like when.

Jeez you guys are scaring me! Our tire receipt shows two ST215/75R14C/ 102N OMNI COMMODORE ST BLK installed 6/18/2014 (we purchased the trailer in 3/2016). We are running at appx. 70 lbs. pressure and have gone appx. 250 miles each way over a 4 day weekend at 70 mph. I suppose we are tempting the devil with this recipe.

Well, when I see 70 psi in a Load Range C tire, and 70 mph on an ST tire, I think you might be tempting the devil. I can't find any information on these tires in a quick search, so it would be a good idea to read what is molded into the sidewall of the tire for guidance on these two factors.

Trailbiker, I agree, it would be nice if there was a kit available for protecting the plumbing. Even though my tires were in good shape and not very old, I wanted to lower my risk of blowout, so this Spring I had some new Maxxis tires put on the TM when I was having bearings repacked.

Rims too have a load rating stamped into the rim..unfortunately it's on the inside of the rim...and to see it you have to take the tire off...UGGG!!....so if your rims are good for 65 psi and your running 70 psi you are not just temping the devil

, you're poking him with a very short stick! I made this mistake and suffered the consequences (KA-BLOOIE!) when the rim couldn't hold the pressure and I also was going 70+ MPH. I made another BIG mistake (unknowingly) of putting "E" load range tires (these were Comode-Door tires too) on "D" load rims (the stock ones from the factory) and ran 72 psi in them....OOOPS! Since then I have gone to rims that are good for, at the very least, 80 psi or more. I would suggest that if you don't check your rims, that you build a blowout cage (or have one fabricated). But just to be on the safe side I wouldn't run more than 60psi (58 would be better) cold in your tires because once your toolin down the road, they will heat up and then the pressure will climb 8-10psi...so if your NOT sure about your rims, be sure about your tire pressure! ....AND GET A BLOWOUT CAGE!

Tom, I think you missed my point, so perhaps others did too.

An ST tire, Load Range C, is rated for inflation to 50 psi MAX. Inflating to 70 psi is way too much.
In addition, ST tires are rated for 65 mph MAX. Routine running at 70 mph is too fast.

Both of these are printed on the sidewall of the tire.

Thanks! Lowering pressure for sure. I will check the tire sidewall. I'd <almost> swear they were max rated for 80lbs max but the information about the rims is duly noted! I will also watch my speed. Any more information about Maxxis tires? Have you mounted those on stock rims or replacements? -Dirk
