Blowout!

glad there is no other damage
yeah could have been lots worse

I put new tires on our dolly last year as the old ones were showing some sidewall cracking. And I keep it inside when not in use....cheap insurance and since I bought tires already mounted I now have 2 spares.

Had same thing happen to me 2 years ago. If it helps, I had TPMS sensors on the dolly, barely gave me about 3 seconds warning when the tire blew. They will help on the slow leaks but not the big bangs.

When replacing both last year, I also went up a load rating on the replacements from my OEM "C" tires that came on my dolly to "D". Gives me a bit of comfort with the 2 extra plys and higher weight capacity.

Most blowouts are caused by under inflation according to the NHTSA, something that TPMS sensors are very good at reporting. There's nothing though, that can warn of an almost instant blowout caused by a sharp piece of road debris.

I did check the tires before departure. 75 psi, max inflation says 80. Could have been road debris.

We got fixed up and the spousal unit suggested that we camp sooner rather than later. Since we were doing a 2 day return trip just means more miles tomorrow.

Gonna nurse these tires.

Will look into upgrading the tires to D. Did that on our old trailer. Liked those tires very much.

How old are the tires? Trailer tires seem to age faster than MH tires.

From an article in Trailer Life ;

"Carlisle Tire estimates that one-third of a tire’s strength is gone in approximately 3 years. Carlisle says to consider replacement after 3 years, regardless of tread depth remaining; and at 5 years definitely replace. That’s just one company’s recommendation.

Yes, and old tires. Sometimes speeding can be a cause. Most ST tires are speed rated to 65.

If those are ST tires, see if you can dump them for LTs, or just replace them every 3 years. In a tow dolly arrangement, the tow dolly tires are the weakest link of the whole rig and limits you to 65 max as stated above (if they are STs).

Just bought the dolly this year. Date code on tire is 2017. They are indeed ST tires.

Do they make LT tires in the 12 inch range?

BTW, got home okay, but kept speed at 65 as best I could.
