Peter,
I had the Geolanders before my current Michelin LTXs. I got just over 50k out of them but they were way beyond used. BUT I had around 80 passes down the strip on them.
They did fairly well through the mudhole at the gate coming out of our property when new.
The Michelins are high but I went with them for the weight rating...3400lbs per tire because of the possible 5ver purchase. There aren't many tires out there that can say that. But you don't tow that much. Remember what I told you about the Excel Energy switching to them from BFGs for mud capabilities.
