Thank you all. I will start to answer some of your questions. Will have to come back for more later. Running low on time now.
The winter/summer tire ratings. It appears by the responses some have used the XPS Rib tire in a winter setting and had no adverse effects. With so much being printed about only using this as a summer tire, I contacted Michelin on this to confirm the XPS Rib can be used in a trailer application and for limited use below 32F.
I made it past the trailer application. With my weights, axle ratings, GVWR and tire size, using the XPS Rib in a trailer application is approved. (as long as the trailer manufacturer is not stating ST tires only) In my case my trailer manufacturer is out of business and I have no placard stating not to use LT tires.
Temperature ratings. Here I ran into issues. The technician had to confirm with their supervisor on this. The XPS has a low end use temperature rating of 45F. They cannot approve any application when used below that rating. I explained this is a trailer situation and not a drive or steering vehicle. The response was if the tire was used in cold enough weather cracking of the tire could occur. They mentioned this may occur at 20F or lower. They also mentioned that the friction will be reduced when used below 45F and they cannot approve the application as the trailer my slide more than normal in the colder weather as the traction grip can be affected.
I asked if I used the tire in a trailer application and if it was used below 45F would this be declared as a miss-application and void any warranty? They responded, that was correct, it would not be warranted.
In our case we do winter camp. We do not go out in snow, but do go out in weather below 45F a fair amount. Actually we would think a winter 45F day is a heat wave. It appears if I wanted to stay within the approved Michelin application and want warranty, using XPS Rib tires is not an approved setup for our use.
I called Bridgestone. Very nice call but no info as of right now. They told me to call a tire dealer for technical info. I explained I wanted the trailer application info direct from the manufacture. They said all their tire technical folks are out until this Friday but could respond then. So this one is on hold for the moment.
However Bridgestone does make both the Duravis R250 Summer and the R238 All season. For some reason the R238 is even cheaper than the R250. So the R238 may be an option. I will "never" wear out the tread on one of these, but I can age out. So needing to go to a R238 all season does not really bother me.
I'll report more on this temp situation as I find it.
Thanks
