LT225/75R16 on a 2011 Jayco33rlds
I posted in another thread my concerns with the ST225/75R15 Goodyear® Marathon Radial on our 2011 Jayco33rlds. I received a lot of good information on different ST tires and some suggestions on upgrad...

Of course that is true of most all of the running gear, but axles, bearings etc. degrade much slower over time than rubber.... So starting with a substantial margin in a tire is a good thing.
I guess the question is how much safer is safer?
My TT axels are rated to 3500 lbs. each or 1750 lbs. per tire, my OEM ST205/75R15 tires are rated 1820 lbs. load range C. A safety margin of 70 lbs. per tire.
When it comes time to change I will probably go to a slightly larger ST225/75R15 load range C rated 2150 lbs. per tire, providing a safety factor of 400 lbs. per tire. If there is enough clearance for the wider tire I can use the same rims.
I could go to a D rated tire and get a 790 lb. safety factor per tire but where do you draw the line? Heck there are some E rated tire that would darn near allow me to go to a single axle.
I have put 10,000 plus miles on the OEM tire and I bought the rig used. The tires will time out before they wear out and the ST225s are about the same price as the ST205s. I only hope they will ride as smooth.
How much is debatable.... I like to get as much as is reasonably possible YMMV.
