After a major tread separation causing a blowout on my FW with the original China made ST bombs, I purchased a complete set (5) of Goodyear Marathons. About a year down the road and probably 3,000 miles, I had two more belt separations on a trip to Michigan last June. Luckily I noticed the tell-tale wobbling on one of the tires while pulling out of the campground one morning and then noticed another doing the same thing while pulling into a different campground that same afternoon. Guess what.....that left me without a spare. (I carry an extra spare on long out of state trips). Out of necessity, I purchased 2 more of the same brand to complete the trip. Since then, after doing a lot of research and the help and suggestions of forums like this one, I have replaced the GY bombs with Bridgestone R250's and have never looked back. To be able to have the very same overall diameter of the GY ST235/80/16 E, I had to go with the LT245/75/16 E. I am completely done with any and all ST China Bombs regardless of Brand.
