I realize the discussion is about ST versus LT tires.
Actually it was a common before the new regulations…
If you check the RV recalls you will find most are to re label the unit because of undersized axles and tires being used…after re-labeling the owner can end up with very little CCC… if their tongue weight claims were not correct maybe no CCC…
Of coarse those built before the new rules requiring actual as built weights might still be using undersized tires and axles because the weights supplied and used by the RV mfg‘s was a bogus representation of the true weights…

I have decided to go with the XPS Rib 235x85R16 Michelin tire. They are expensive at $300 each but I feel better with that tire than I do with the LT series. I still don't know the wisdom of this and the outcome this summer while traveling over 8,000 miles, but this is the way I am going. We leave in June for an extended trip so I hope I have made a good choice. If I find out before we leave in June that this is not a wise thing to do then I will change again. I will not however go with a 17 inch tire because of the expense of buying new wheels along with new tires.
Thanks for all the good input on this subject I will let you know how it all works out.

Dixie Flyer wrote:I have had so many problems with Good Year Marathon tires I am thinking about going to a Michelin LT 235 85R 16 tire to replace the ST235 80R 16 load range "E". When I check the load range on the Michelin tire it is 400 pounds less than the Good Year which is rated at 3,400 pounds. The Good Year tires are two years old and I am stuck in Williamsburg Virginia with four tires with tread separation and blisters and can not get home until I but tires.
My Montana weighs 13,000 pounds as it sets, so I need a tire that will carry that load. The tire dealer I am talking with is trying to sell me LT tires and I am concerned about them not being able to carry the load. Can somebody help me with good information?
IMO - GY load rating is a joke - as well as the tire!.
Try a search for ST vs LT Tires in the *archives* (over 1yr old).
Discussed at length. Also continuously in the 5th wheel and Tech Issues forums.
Try this hands on test:
Go to a tire dealer that has a GY Marathon available.
Lift the tire. Try to compress (push down on) the tire.
Now find a Michelin XPS Rib and do the same. Night and day!
Try a search on "Marathons" -or- "Goodyear Marathons" to help you decide.
("Goodyear Balloons" might work too!)
BTW - check the clearance between the tires.
Google - tire size comparison charts for sizes in inches.
When you go to LT the 235/85 will usually be an inch larger in diameter. (Which equals a full inch between the 2 tires)
You may want to go to 245/75. It will be a *half* inch wider per side.
Also - usually the LTs will require 80psi. Check your wheel psi rating. Usually stamped on the back side of the wheel.
You found a good tire dealer!
Go with Michelin or BFG (owned by Michelin), or other *quality* LT tire.
Roll on!

But several high end 5er's come from the factory and are stickered to take LT tires. My last 5er an Alpenlite was one and it had Goodyear Wrangler LT tires on it from the factory. The Montana I just bought had brand new Marathons on it and after the trip home it now has BFG/TA's. I think LT tires will handle more weight then they are marked at and will take more abuse then any ST tire out there. I think the right size is 235-85-16. You will have 1 inch less space between the tires but a BAL wheel chock still fits fine.
There not stickerd for LT265 size tires. Read all of my reply as you are misrepresenting what I have said. If you notice the tire size is LT265 which no trailer manufacture uses or is the 265 size a option. The 265 is simply not the best choice for a tire on a trailer.
Agree with the rest of your reply on ST vs LT.

You are going with a tire thats a 1000 pounds under rated with no gear aboard?

To answer your question as to when they started making the XPS tire I have no idea. to answer another poster the Good Year Marathon tire was rated at 3400 pounds and the Michelin XPS is rated at 3042 pounds. I had rather run the Michelin tire rated four hundred pounds less than to run the Good Year. Too many times I have been left on the side of the road with a blown Good Year tire, it is time to try something different
