Well I was really down on Hutchinson tires but they have just renewed my faith in them. I had three UST Pythons and cut them all on the trails. Trails I've ridden on many times without problems from other tires. So I marked the cuts and sent two of the tires to Huchinson. After about 8 weeks without any response I had given up on ever hearing from them. Today UPS delivered two new Tech+ Tubeless Python tires! These are $55.00 tires at a local shop. Props to Hutchinson for standing by their products. I think from reviews I've read that they had some problems with their original tubeless tires, (as did other manufacturers), but the new ones they sent are the Tech+ Tubeless. Hopefully they are a tougher tire. Can't complain for free though. I guess the squeaky wheel does get the grease!
