e*thirteen TRS Race Tire 29x2.35

e*thirteen TRS Tire Review

November 2016 Reviewed by: Scotty

I've never been much for getting my bike perfectly tuned. Whether you slap a 15mm or 25mm rise handlebar on my bike, I wouldn't notice the difference. The same went for tires, or at least DID, until I rode e*thirteen's TRS tires. For the first time ever, I understood what real traction was, how dramatically a tire's casing affects ride quality, and the nuances of a tire's tread pattern. e*thirteen put an incredible amount of effort into this tire and it shows.

Note: TRSr tires feature an ultra-tacky triple compound rubber, while the TRS+ tires sport a more long-lasting dual compound rubber. Because e*thirteen's TRSr and TRS+ tires are otherwise identical, the reviews are the same for both sets of tires.


I truly had no idea that a casing could so dramatically alter and enhance a tire. Fact: San Luis Obispo eats tires. Pinch flats are common and extra tubes are a must. I can sum up the TRS casing by simply saying: I no longer carry extra tubes. It's a bad habit, I know, but it's true. I just don't pinch flat anymore. The casing, which is called an "enduro" casing in the current parlance, utilizes an extra layer of protection as well as an ultra-slow-rebound rubber, which makes this tire predictable and forgiving through rocks. The casing offers the feel of a DH tire without the extra weight.


The TRS's tread is reminiscent of a few other tires on the market, namely Michelin's Wild Rock'R and Maxxis's DHR. The only difference is that the TRS is better... by a longshot. Not only do both TRSr ("race" triple compound) and TRS+ ("durable" double compound) offer insane amounts of bite thanks to their compounds, but the well-spaced, ultra-beefy, and super-angular knobs grab hold of anything and everything on offer. From loam to loose rocks, even on hardpack, this tire has traction for days. Initially, it felt a little bit slow while pedaling, but the tradeoff of monster traction on the descent is well worth it.

Another thing worth mentioning is how predictable e*thirteen's TRS tires actually are. These tires let me know exactly how hard I could push before they'd let go and when they finally did, I knew precisely where they'd go, how far they'd go, and how quickly they'd get there.


At 950 grams, these tires punch well above their weight class in terms of both traction and durability. I'd previously loved WTB's Vigilante for its predictability and traction, but at around 1100 grams, I got more flats and less traction than with the TRS tires. Being able to ride with the type of confidence that these tires offer, knowing that your tires won't leave you flat and bummed is well worth an extra 100 grams or so.

Bottom Line

e*thirteen's TRS tires are, without a doubt, the best tires that I've ever run both front and rear. Incredible casing, monster traction, and ultra user-friendly. I'd recommend a TRSr (race) up front and a TRS+ (plus) out back.

Super supple (and durable) casing, ridiculously predictable traction, and unbelievable amounts of traction.

If weight is a concern, 950 grams might seem like a lot, however, the traction is worth it.

The Verdict

Buy these tires immediately — they changed my life and will change yours too.
