Had my third blowout in three years on Saturday, again, an inner rear dual. I have replaced four of the original Dunlops with Bridgestones, and can't wait to biff the other two Dunlops on the rear out and replace them with Bridgestones as well. This blowout threw about one metre of tread off the tyre, luckily, no consequential damage, apart to my wallet. The one fortunate thing was it was only 50m from the Bridgestone agent, but it still cost me a callout fee on a Saturday night of $150, plus $625 plus fitting for the tyre. If he had had three Bridgestones in store, I would have done the lot at once, but I won't be driving far till I can do the last two. I currently have a brand new tyre as a spare, and two older Dunlops on the rear to keep a pair.

I am getting better at removing the wheels myself, the hardest bit is putting the spare back up on the frame at the back for travelling. I know many on this site don't carry spares, but I wouldn't be without one after my experiences. My one regret, is that the TST TPMS did not show an overheating tyre, because (I suspect) of the valve extension on the inner tyre. I had no warning till an almighty bang. The Dunlops are showing quite a bit of wear according to the agent, so they may be quite old.

It all adds to the fabric of life, and gives me wonderful stories to share with you all, but given that I have replaced the awning ($2300), the batteries ($1850), the tyres ($2000) and the bed mattress (by choice, $1500), I am scared I am going to have to go back to work!



Please call me regarding your recent blowout you had.

When you replace a tire in a pair of duals do you confirm the two tires match each other +/- 3/4" circumference. To fail to match tires you are almost guaranteeing another failure as the larger tire is now in an overload condition.
The other this is what happened when the first tires failed. Unless you had a TPMS and stopped immediately you drove some number of Km with the not yet failed tire in a 100% overload condition.
