If you are shredding sidewalls, take a look at the Specialized Team Control/Team Master set up. The weights a little higher than the Python (although lighter than any UST), but they consistently do well in the rolling resistance tests and they grip very well, better than the Pythons IMHO. Plus they have a thicker sidewall that would be harder to shred. The trade off is that they aren't as tall as the Pythons, so you lose a little volume, but you have a full suspension anyway.thejuru said:
For lighter weight, try the Kenda Karma DTC's. The sidewall "feels" tougher than that of the Python, but I don't know if that will hold true in real life. I used them in Mammoth, including Rock Creek trail and they held up great. I run them tubeless also (Eclipse). All 4 of my Karmas weigh between 453 and 472.
Also, the Racing Ralph 2.25. I am trying one right now on the front (with a Karma on the rear), and it feels tough for a racing tire. Nice big volume too. Mine weighs 509 grams, 15 grams or so lighter than my Python Airlight.
I've run all of these tubeless with no problems.
