Well, did my oil change and while under the truck I noticed the inside of the right from tire had a slit in it about 1/2 in. out from the bead and about 1 in long. Darn Goodyear tires. I only have 39325 miles on the truck with over half the tread still left on all. Looks like a trip to the Goodyear store. Plenty of reading on here about it. Just do a search.
