I picked up a set of e*thirteen tires and have been loving them. I am running the TRS Plus in the rear and have the ultra tacky TRS Race in the front. The combination of the longer wearing TRS Plus in the rear and sticky-icky TRS Race up front is ideal for someone who wants to get decent life out of their tires but doesn't want to sacrifice grip to do so.
For some context I have ridden a ton of different tires over the years from Schwalbe, Continental, Michelin, Kenda, Vittoria, and Maxxis. When it comes to spending my hard-earned money on tires I typically go to Maxxis. I believe they have figured out the best combination of grip, weight, and rolling resistance. My go to set up is a Maxxis DHF up front and DHR II in the rear which is ideal for the loose-over-hard conditions typical in Utah. e*thirteen has brought to market an excellent rival to the Maxxis DHF/DHR II combination. In fact, I tend to think the TRS Race/TRS Plus combo offers more grip than the equivalent Maxxis combination. The over-sized side lugs offer excellent cornering grip in all conditions I have encountered. The Apex casing is super durable and I haven't had any issues with flats. I would have given these tires 5 stars if they rolled better. They roll well for a super aggressive tire but compared to a DHF/DHR II combo they are noticeably slower rolling.
If you're always looking for the next greatest tire combination, and you like aggressive tires, I highly recommend the TRS Plus/TRS Race combination.
