I am planning on spraying rubberized bed liner stuff in the wheelwells down the road (pun intented)
I would suggest I20 in TX around July 4th.... when temps are hitting 100*F and up We blew a tire out on the Jeep while towing it (UNLOCK THE STEERING WHEEL BEFORE LEAVING A CAMPGROUND!!!). Luckily we had a "donut" spare but needed to replace the tire. Stopped in at a Wal-Mart not far down the road from Ft Worth to get a spare and the tire guys looked at all our tires covered in road tar. It was about an inch thick on our rear tires. That was in 2009. We finished to trip out to Socorro (NM), and have gone down to Corpus Christi and back... I still have some tar on the Class C's wheel wells!
