I'm new to the forum. I've had 4 TowMax blow on me. Two due to junk on the road. Two just blew. In reading other comments regarding this issue, it appears TowMax are junk and the good year g614 are a good option. I'm of the understanding any st tire has a max speed of 65. And the good years are 110+ allowing for cruising at 70-75 mph. Two questions....1) my rims are 6" wide and the good years are 6.5...will the good years fit? 2) the stamped max load on the rims is 3200 lbs...that's even less than the TowMax rating. The good years are approx 3700 lb rating......will the rims still work? Thanks in advance for your help.
