I realize I wasn’t very clear in my post. I wouldn’t say the camper has not travels much at all in the last year. It’s made a run from MI to Phoenix AZ each spring and each fall every year. Then the previous owners camped tough out MI for summer trips. I agree sketchy tires and the possible $$ repairs is a big influence in this decision.
I hear you on the searches and all the info I have read through a big chuck of that stuff. To the point I still feel like I am still in a gray area. Maybe just gray by our own making.
I will do more reading on Michelin Ribs and Bridgestone R250’s. I was under the assumption that the Sailum’s were not made in the US. I thought I read they were made in China. I would prefer to stick with a US made product if possible. The only reason I tossed them into the mix is they seem to have good reviews. I think I read somewhere that the Marathons were manufactured in the US at one point then went out of the country (when the problems started) then came back to the US. In any case I don’t think I want to take a chance on them.
Amen to the beating I have taken a few of them over the 45 years. That would just about be my luck to get new ones and have one blow and damage the rig. I would just humbly head right to the virtual wood shed waiting for DW and my flogging to start. I forgot to mention crows fly around our house because they know they are part of my normal marital diet.
Not sure on axles and the GAWR it’s still at our county fairgrounds in one of the barns there. I can’t get it out until next Saturday. It does have 8 lug rims on it that’s for sure.
I guess it didn't sink in until now that if I was going with a tire that could handle heaver weights 4080# it would take 110 psi and put me over my rims rating. Maybe that makes the Endurance a reasonable trade off for me. We are making it our goal to travel as light as possible. But I bet a whole lot of people have that goal and don't realize how it all adds up. At some point I want to get the whole rig weighted. I do know the truck weighs in at 7920 with the hitch in and the wife and I and full of fuel.
I am getting the feeling it would be a wise move to just replace them.
Thanks for all the opinions shared.
