eTHIRTEEN Grappler Tire Review

One could easily argue that tires are the most important component on a bicycle. They are your only point of contact with the ground (hopefully); play a critical role in your suspension systems, and are the biggest factor in the rolling speed and feel of your bike. Given all that, it’s no wonder that people tend to choose their tire preference and rarely deviate from it, even though there might be more to life than the classic DHR/DHF combo. With a mixed history in the tire market, e*thirteen has long been an option that many people haven’t tried, but the engineers there are hard at work to change that. From my time on their brand new offering, the Grappler, I can confidently say that these tires deserve a place on more bikes. Maybe even yours.
THE DIRT
I started this test riding the MoPo DH Grappler as a front tire, in and around Bellingham and up in Squamish, BC. Immediately upon airing it up, I was pretty surprised by how stiff the casing is, even compared to other downhill tires I’ve run recently. This feeling didn’t really shake as I started riding the tire, as it has a really stiff, almost wooden feel on trail. That being said, this is a downhill tire, meant mostly for park riding and all-out abuse. On my regular trails, which can still offer plenty of speed and challenging terrain, it’s likely just overkill.
This initial reaction was quickly dismissed when I switched over to the Enduro casing. The more supple casing instantly produced a night and day difference. Both the DH and the Enduro have excellent tread grip, but the Enduro has a much more pliable casing, which allows it to conform to the terrain better. Any hesitation and feedback I felt with the DH casing were calmed by its lighter brother, and I stuck with the Enduro for the rest of the test.
One can pretty easily guess the tire that influenced the Grappler’s general design, as the tread pattern is distinctly Assegai, with its 3-2-3 center lugs and meaty outer edges. Where it differs is in those smaller 3-pack lugs, where the e*thirteen version has a much more substantial appearance and feel. This was noticeable on slab trails, like those up in Squamish, where the tire effectively has a larger contact patch than other equivalent designs - meaning more grip when cornering and braking. I also felt a difference on the greasy roots here in Bellingham; thanks to the super-grippy nature of the MoPo rubber, you can catch decent traction on slippery surfaces, but the solid base to the lugs don’t let them squirm as much, so the whole tire feels more stable. I don’t necessarily think the MoPo is a whole lot stickier than MaxxGrip or Schwalbe’s Super Soft, but all three offer best-in-class performance when it comes to wet weather riding.
I had the Grapplers mounted up to 3 different wheelsets I’ve been riding, the Stan’s Flow MK4s, the Reynolds Trail 329s, and e*thirteen’s own LG1 Race Carbon wheels. The internal widths vary slightly on all three, from 30-32mm, and in every case the Grappler aired up nicely with a round profile: not as domed as some tires out there, but not as squared off as e*thirteen’s older offerings. Those older square tires were a bit notorious, for when you pushed beyond that outside corner, things could get hairy. According to the engineers at e*thirteen, they’ve done a lot to tweak that casing shape and get it to fit a more predictable and stable mold, and I think they’ve hit their mark. The 2.5” width is spot-on for the intended usage of the Grappler, looking and feeling appropriately aggressive without reaching the balloon-like vague levels of some bigger carcasses.
Over the months I’ve been on the Grapplers, I’ve ridden some fast hardpack California trails, which are already getting dusty, and the cornering performance was just as impressive as it is here in the PNW loam. The big square lugs of the tire really dig in nicely, but you don’t have to commit to a fully tilted lean to get that bite. That feeling is part of what makes tires like the Assegai and Magic Mary so appealing, and e*thirteen has captured it well. Like any beefy knobby tire, braking performance is excellent, and the lack of ramping on the Grappler means it hooks up in damn near every direction. This of course does equate to lower rolling speed, but for my riding that matters a whole lot less than the grip you can get in the steeps. Tread wear is pretty slow here in Bellingham, but even after a few weeks of hot rocky riding in California the knobs are still in pretty good shape, with minimal undercut and no tearing or punctures to speak of.

This guy killed this review, nice job Bud!

[@TheLoamWolf]

Thank you!

[@tahoeebikes]

I think the schwalbe super trail addix soft are the best overall tires but getting crazy high price. These look so good must try.

[@86309]

Funny that you talk durometer, while showing a squeeze of the sidewall. thats a good one.....Great review though!

[@smtkelly]

Nicely presented

[@TheLoamWolf]

Thank you! Cheers!

[@marklouieadame]

I am an e13 tires they are true to their words when they say 2.4inch size it really is 2.4inch. The compound is grippy and can really take a beating. I wanna try the semi slick for my fast and dry trail riding

[@excelautodetailingceramicc1182]

When did the serial killer glasses come back in style?

[@TheLoamWolf]

Did they ever really leave?

[@alexnelson9505]

It would be nice to have a direct comparison to the benchmark DHF and Magic Mary. I've moved to Eddy current tires as they hold up like nothing else.

[@ostankovalex1176]

try out Hutchinson Griffus :) if found them to slay DHR/DHF without any issues great grip and rolling

[@TheLoamWolf]

Right on thanks Alex. We like the Eddy's too!

[@montyroach_rides]

I agree. I went from DHF/DHR to Eddy Current's. No way would I go back after using the EC's now. Solid tires.

[@SpencerBaum]

Wow! Another assegai!

[@jaysealenduro5618]

Any reviews about Michelin wild enduro racing lines?

[@GiovaniUrrutia]

Step up in production quality, what changed?

[@aaronburela432]

How would it compare to specialized butcher?

[@trentvlak]

I heard they were undersized.

[@21armyn]

dario any reviews on the new continental tires??

[@TheLoamWolf]

theloamwolf.com/2022/10/26/reviewed-continental-kryptotal-argotal-review/ Got a full written review from Dario right here.

[@martinhayes5087]

"mum, I want an assegai" "No sweetie, We have assegais at home" * the assegai at home* 🥴

[@rohanjs.]

I prefer these over an Assegai 😅

[@Calispeedboi]

Better than an ass guy those are big claims 😯 might go hunting for some on sale
