Ballooning is on the rear drive tires. I DO NOT have vents cut in the tread of the tires only the wheels are vented on the inside. Using closed cell foam inserts. Its possible water got inside the tire but I'm pretty careful about not submerging them.

The tires are pretty new so its just odd that one ballooned so quickly. Only the second weekend I have used these tires.

I've heard both sides of keeping tires on the same side vs. rotating them. To be honest have never noticed a difference either way.

Anyways, wont drag this on. Was just wondering if anyone had ever had this happen.
