I have been running a set of bias 42'a on H1's with a pvc beadlock under a linked YJ 60/14. When I first started running the tires the sidewalls seems very stiff. After several rides and pressure adjustments the tires were broken in and performing very good. After 4 years I have had to have one sidewall vulcanized. I feel it was MY FAULT for having too low of pressure and it pinched between a rock and the rim and cut it. My Jeep sees very little pavement and the wear is acceptable. I wheel 1,2 times a month.
I honestly feel the compound and width of the 42's is very very good, not a sticky tire but still good for a trail rig. $2K for a set of tires mine need to last for a while.
If I have to pick another set of tires it would be the TSL SX only because I am limited to the 16.5"
In the very near future I will be needing a 37"39" tire in a 16.5" rim for my buggy and the decision will come down to price between the Rockers and the SX.
