I need a tyre that is really durable, puncture resistance, folding, lightweight and good for rocky (sometimes loose) and dry terrain. I work as a guide in Georgia (Caucasus) and my tyres wear out too quickly.
I really like some of the WTB tires. Specifically the Bronson and the Weirwolf. It's tough to find a tire that's going to do it all, but I think WTB is a good mix between weight and durability. I also really like the traction of those two tires in a lot of varying conditions.
When you say "they wear out too quickly" how quickly are we talking? How many miles/rides/weeks...
Another thing to consider, if you are riding tubeless (or willing to do the conversion) I have had really good luck with Stan's sealant to keep punctures to a minimum.
Also, are the tires wearing out due to treadwear, punctures, sidewall tears? Those two tires are a really good balance all around but if you have specific concerns/issues, you might get some better recommendations.
