Had my first tire blowout today. Have a 2003 Jayco Granite Ridge 3100ss that we picked up little over a year ago. Coming home blew the passenger side inside rear tire, luckily right at exit off freeway and a short distance to tire store. Tires less than 2 years old, less than 6,000 miles, 80 pounds pressure. I have cut as much weight as possible, outside storage to a minimum, but still had the blow out. So the question is: can I solve this problem without getting the load G wheels/tires or do I sell the rig? We travel 85 miles to camp, I drive 60 mph or less, unit drives like a dream so I feel weight distribution must be OK. I am at a crossroad here, we love the rig but from what I read in the forum here there is no solution other than going to heavy duty rims/tires, may be time to sell the C. Any reliable tires out there you recommend other than light duty truck tires that will fit stock rims? Thanks in advance. Jerry.

I have used Firestone Transforce tires, load range E. This is my second set, the first were load range D. Used them from 2004 to ~2009 or 10, saw some cracking and replaced them with the current set. The current ones still look great, probably will replace them next year with the same. We now have 44000 miles on the rig.

My question first is were the tires 2 years old from purchase date or build date? Many tire stores will sell old tires that are still in stock. What size tires do you need?

x2 on the actual age of the tires. Let me add, Rear Inner has three things going against it:1. If all four rear tires are same diameter and pressure (and they must be) a crowned road puts just a little more load on both inners.2. Inner duals don't see the air flow that outers do, and probably run a little hotter. But the passenger side inner on E-Series receives heat from the tailpipe.3. If we drivers drop the outer dual off the right shoulder of the road, ALL of that side's weight gets thrown to the inner dual.I like to think that if some college graduate engineer thought the design called for "more" tire, s/he would have specified so. But then, some MBA might say not to go overboard on tire cost.

First, weigh all four corners of the RV at the wheels. That will tell you if any one set of wheels is overloaded. If it is, then decide how, if possible, to reduce the loading at that corner, or get higher rated wheels and tires to carry that load.Just because you had a blow out does not mean you are overloaded or you need to sell the RV. The tire could have been defective, the valve stem experienced a rapid failure, or a road hazard caused the problem.

Tires do fail. We do not like it and you can take all the precautions you want but they can fail. You do mention how you have trimmed weights on the RV are You over loaded? And X2 on age of tire not buy date.One precaution I would take now is to replace the passenger side rear outer tire. Reason it has been subjected to a major overload.

Just like any vehicle a tire can start to go flat and then ultimately blow out.

It doesn't always have to be the result of a bad tire. It starts to go low and if continued to be driven on they blow out and strip the tread right off similar to a bad tire blowout. It's from my experience that I've seen this when I had 2 'blowouts' on one trip. I TOO immediately thought it was bad tires, found out it was bad valve stems. Most RV'ers go right to 'bad tires' when it can be other things. Just saying.
