Maxxis M8008 is whats on our 3 car wedge (We don't have a toy hauler) just remember being a trailer that they will rot out of the safe service area before they are worn out
we had a China King pop on a flat bed that wasn't even moving, it was sitting in the yard and it blew out, the tire was 1.5 years old.
Also, be weary of closeouts, do you know how to read a dot code? On every tire there are 3 sets of numbers/letters that will tell you where it was made, who made it, and when it was made, the last 4 are when, first 2 are the week, last 2 are the year
so a tire with dot code B6LB CKXX 4212 was made the 42nd week of 2012.
Reason I posted that, is if you're buying from a little mom and pop store's clearance event, you could be buying tires that are already 3-5 years old (I've seen it)
