First Look, First Ride: e*thirteen's Reinforced Tires

Changing tire manufacturers is a risky proposition, but e*thirteen's new tires don't skip a beat. They'll also be available in greater quantities and downhill versions.

First Look, First Ride: e*thirteen's Reinforced Tires

How do you make a great tire even better? It has to actually be available, for starters.

In 2016 e*thirteen released their first tire. Those who tried it, including Vital, were by and large impressed. We were very pleased with cornering traction, noting that the tires held quite a bit longer than most when it came to laying it over and pushing hard. We also found ourselves braking later and later into corners due to the tire’s excellent braking traction and overall control. The even, slow wear of the tires was another standout characteristic we enjoyed.

Word spread and demand increased. As time went on, though, e*thirteen was faced with the reality that the previous manufacturer could not (would not?) produce enough tires to meet demand, and the brand was forced to look to another manufacturer. Enter VEE Tire Co.

Our first TRS tire was an instant classic... Grip was the end goal, and these tires were the ticket. After winning multiple tire shootouts and with positive reviews from media and end users alike, we felt there were still some improvements to make. - e*thirteen Components

Making the switch to VEE might have a lot of you concerned that quality might not remain consistent. VEE is still a relative newcomer to the scene and has yet to really prove their merit on the enduro/downhill stage.

Curious to see what the difference amounts to on the trail, we've been riding a pair of the new TRS Race tires to see if there is a noticeable change. We also have some old versions on hand for a visual comparison. With the tires side-by-side, you're able to see both slight and major differences.

New TRS Race tire
New LG1 Race tire

The biggest difference is increased casing thickness on the new tires. e*thirteen is now offering the tire in both a single ply TRS version and a new dual-ply LG1 downhill version, which is very stout. For comparison, the three photos above show the casings of an old TRS Race tire, new TRS Race tire, and new LG1 Race tire being pinched by hand very tightly. There's far more material and overall casing thickness on the new versions.

For 2018, our TRS tires are reengineered with a more stable, supportive casing and better puncture protection. We now also offer a dual-ply LG1 downhill version with the same all-terrain tread pattern and true 2.35-inch width.

Looking closely, we observed slightly shorter, less deep center knobs with just a few degrees less ramp than before. Slight misalignment on our samples also resulted in some tread inconsistencies, jagged center sipes, and slightly misshaped side knobs.

An additional change we noted is to the side knobs, which now have a little less side-siping. The fancy pattern on the sidewalls is also gone, although the new Race versions look equally interesting thanks to a woven layer of aramid showing through.

Whether intentional or not, according to e*thirteen all but the casing changes listed above are "effectively cosmetic" and "don't affect performance."

e*thirteen Tire Specs and Features


  • Same true-to-size 2.35-inch tire width for both TRS and LG1 tires
  • Same ultra-grippy tread pattern
  • All tires have Apex inserts for added casing support, as well as cut protection.
  • Race tires feature a layer of woven aramid reinforcement that not only maximizes air retention, but better protects against sidewall cuts and punctures.
  • Available in single-ply TRS casing for enduro and dual-ply LG1 for downhill
  • Available in both Race and Plus compounds
  • MSRP: Race - $69.95, €74.90 // Plus - $59.95, €64.90

"Race tires use a slow rebound, tacky [52a durometer] rubber compound for maximum traction, while the side knobs use a high-tack [48a durometer] compound to maximize cornering and off-camber grip. Plus tires utilize the same tacky, slow rebound compound over the entire tread, without the high-tack side knobs. Both Race and Plus tires exhibit excellent wear characteristics due to high compound toughness as well as excellent load distribution on the tread under heavy cornering and braking."


Actual Weights

  • Old TRS Race: 27.5 - 900g
  • New TRS Race: 27.5 - 1,020g
  • New LG1 Race: 27.5 - 1,130g

On The Trail

To see how these changes translate to the trail, we've ridden approximately 40 miles on the new TRS Race version. First we tried them out on the loamy steeps of Santa Cruz, then a variety of loose-over-hard pack, sand, clay, and rock-strewn trails in San Luis Obispo, California, home of one of e*thirteen's office locations and the 2015 Vital MTB Test Sessions.

We're pleased to report that the overall performance of the tire has not changed dramatically in one way or another when it comes to grip and control. The most notable change is a result of the casing updates. Previously, when heavy riders were cornering hard or subjecting the tires to major loads, the sidewall would occasionally collapse on itself depending on the pressure riders were running. That's much less likely to happen with the new casing.


At a given pressure, the tire does act a little differently through rocky terrain by translating more bump feedback to the rider. The new casing is just a bit firmer-feeling, and it's possible that the rubber is a bit less damped than before.

Our 175-pound tester has found the lighter TRS Race casing to be sufficient in all listed trail conditions, and riders who were content with the support the previous version offered may even be able to drop a few extra psi without worry. Even so, e*thirteen's Connor Bondlow, who weighs in at 200-pounds and rides quite well, prefers to use the heavier LG1 Plus rear tire on his pedal bike for rough, rocky trails.

Another notable change is the weight. The new tires gained 120-164g, depending on the tire diameter, model, and compound, but the added weight comes with improved sidewall stability and cut resistance – two things we'd gladly take in exchange for a few extra grams.

While e*thirteen claims that rolling resistance is decreased as a result of the new Apex insert, we didn't feel a noticeable difference. Rolling speed continues to be the tire's only real downside, which is why we prefer it as a front-only tire on our trail/all-mountain/enduro bikes. For lift-assisted use we'd happily mount a full set front and rear.


What's The Bottom Line?

Despite a factory change and slight visual differences in the tread pattern and manufacture quality, e*thirteen's tires are still awesome – a testament to just how good the tread design is. Thanks to a new casing they're now better suited for heavy and more aggressive riders, and sidewall cut resistance is also improved. This comes at a slight weight penalty, but the tradeoff is worthwhile. The new TRS Race tire is one we'd love to see come stock on the front of more enduro/all-mountain bikes, and the LG1 versions offer a lot of promise for downhill use.

Comparing Gen 1 vs Gen 2 of the TRS+ version

...while waiting for the new Gen 3

Rating: Featured Member Review
The Good:

-Not the most expensive even at MSRP
-Good rubber that seems to last
-Good flat resistance

The Bad:

-Rolling resistance vs grip ratio

Overall Review:

Those who have read some of my reviews probably know that I am quite picky on everything, but tires are the part that keep me the busiest. I had originally purchased the new revisited 2018 E Thirteen TRS+ tires from JensonUSA, but after seeing pictures and reading reviews, the new squarer shape turned me off a bit. Before even mounting them on, I heard that they still had some of the “Classic” version in stock at E Thirteen. Shortly after, I saw that Jenson had them in stock for a closeout price, so I took advantage of their returns policy, returned my 2018 and bought 2 pairs of the older version in the TRS+ compound.

The older version is rounder, has a bit more volume than V2, a bit lighter carcass, the same big side knobs, wide open channel, and grippy center knobs. That’s pretty much the recipe for a winner for an all-mountain/endure/mountain bike tire. I ride rocky trails but my runs are always around 20-30kms so I need the tires to have good sidewalls while still be quite well rolling. 


Coming from a pair of Specialized Butcher Grid, I started the season on the fresh E13s and on my first ride I had the impression that I was rolling on a flat tire. Transitioning from the Butchers to the TRS+, I had never felt a difference in rolling resistance as pronounced as this. Maybe the off season was harder than I thought, but I was glad I didn’t get the grippiest TRS race version. 


After a few rides, I was used to the added rolling resistance and started to like the added grip vs the Specialized Butchers. They had similar tread patterns : big and constantly-spaced side knobs, wide channels between the side and center knobs, and two rows of knobs in the center. Looking back, if the Specialized Gripton rubber would have been a bit stickier, I would have liked them more, but even with the added rolling resistance, I think that I prefer the E Thirteen. While quite big and being made of their hardest rubber, I found the side knobs still a bit easy to fold in corners. I need to run 2psi higher pressure than the Butchers, who had similar volume but thinner sidewalls.


Now they have just released a new V3 version that looks even better than the Gen1 : new redesigned side knobs (L-shaped, between a Minion and Butcher, and shorter for less knob-leverage/folding in corners), bigger center knobs, new compounds, at around the same weights (1042g for the 29” double ply Enduro version). If the new tread rolls faster, I think they would be pretty good for long and rocky rides.

Poor traction on rock and loose

The Good:


The Bad:

Poor traction on rock and loose, rolling resistance, sidewall and puncture durability

Overall Review:

These tires suck when it comes to loose over hard and rocks. I've been riding them for the past four months and I've washed out the front end four times. I also got a pinch flat on my very first ride. I don't know if it's the tread pattern or the tire compound but these tires seem to slip when it comes to loose over hardpack trails which is 99% of the trails in Colorado. They rail berms quite well but when it comes to the terrain you see on actual trails these tires do not inspire confidence at all, not one bit. Maybe they're different in loamy or wet soil but rocky and loose do not buy these tires.

The Best Got Better

The Good:

Outstanding grip in all conditions. Better puncture resistance and sidewall support than the original

The Bad:

Slightly heavier than the original

Overall Review:

I was a big fan of the original TRS tires for where I ride in North Vancouver and Squamish. The grip the original tires provided in the wet was better than anything else I've tried. The grip on this updated version is the same, but I can run a few lower PSI due the the improved casing. I run the TRSr in the front and TRS+ in the back for longer wear and slightly better rolling resistance. Awesome product.
