Reminiscent of the nice ol’ days of lengthy bar ends and loud colors, the Onza Canis 27.5 x 2.85” Skinwall tires not solely look nice, however supply low rolling resistance and sufficient tread to deal with a variety of path circumstances. Learn on for our full evaluation after driving dust, sand, roots, and rocks throughout British Columbia, Colorado, and past…

Skinwall tire choices are in every single place nowadays. Manufacturers like Teravail, Maxxis, WTB, and Onza are all providing barely modified editions of a choose few of their benchmark tires, which in some instances creates a lighter and extra supple tire, relying on what sort of sidewall course of is used. Within the case of Onza’s restricted version skinwall tires, which embody the Ibex, Citius, Canis, and Svelt, the sidewalls should not handled with butyl rubber just like the common ‘black’ wall variations, leading to a little bit of weight financial savings and main road cred. Whether or not or not you’ve good causes to go for a skinwall tire, you may certainly count on a praise or two and an aesthetic sprint of color to your present bikepacking rig. Skinwall tires are in, at the very least for now.
Setting the Onza Canis tires up on the inventory Alex MD40 rims on my Karate Monkey proved to be a much bigger problem than anticipated. I first tried the setup with high quality flooring pump. Not even shut. I introduced the wheels to my native bike store the place in addition they tried with a flooring pump, no bueno. Out got here the compressor, and even with elevated stress, it was all fingers on deck, plus a couple of different bike mechanic methods, to get the tires seated. I do know this typically comes all the way down to the rim in use, together with the inner profile, form, and width, however I figured it was price mentioning anyway. Just a few satisfying pops later and the tires haven’t come off in over 4 months now, and have wanted little or no repairs to keep up their tight seal. The 40mm inner width of the Alex MD40 rims hits a candy spot for this measurement of tire, permitting some wiggle room if I select to return to a real three.zero” tire and even mess around with the newish 2.6” mid-plus choices we’ve seen, together with the Maxxis Rekon 27.5 x 2.6” tires.
27.5 x 2.eight” Tires In contrast
The Canis 27.5 x 2.85” skinwall, which is at the moment solely supplied in a 60 TPI model, weighs simply 70 grams greater than the usual 120 TPI model, coming in at 910 grams. In comparison with different 27.5+ mountain bike tires accessible, the Canis’ weight appears to fall proper in between the usual gentle casing and hard casing choices. For instance, the Maxxis Curler II Plus (27.5 x 2.80”) weighs in at 915g (120TPI) and 970g (60TPI), and the WTB Ranger (27.5 x 2.80”) weighs 803g (gentle casing) and 1044g (powerful casing). The skinwall will prevent a bit weight, and, after a fairly intensive evaluation interval, we are able to verify that it received’t fall brief in terms of sturdiness, significantly within the sidewalls. We should always observe that the 27.5 x 2.85” model can also be supplied in a 120 TPI freeride casing that shares all the identical specs because the skinwall, however is available in at 840g on the expense of some sidewall sturdiness. Past the 27.5+ choices, the Canis is available in 27.5 x 2.25” and 29 x 2.25” in a number of completely different casings, skinwall or not, and numerous TPI choices. All are tubeless prepared, and make the most of a twin compound that’s made up of a tougher, longer sporting rubber in the direction of the center of the tire and a softer rubber for cornering grip.
The mid-plus 2.6” to 2.85” width is a candy spot when it comes driving on bigger than common tires, particularly on the 27.5 platform. They roll rapidly, supply virtually an identical driving traits as three.zero” vast tires, like floatation and traction, however can nonetheless deal with technical terrain and tight corners playfully. In the case of singletrack-heavy bikepacking routes, it’d be laborious for me to return to anything at this level. I used the inventory Surly Grime Wizards (27.5 x three.zero”) on my Karate Monkey final fall, all winter, and into the spring. They have been just about indestructible and offered extra grip than I knew what to do with. Nevertheless, they weigh in at round 1,225g, over 300g heavier than the Onza Canis, and the aggressive tread meant I wasn’t going wherever quick, except it was a gnarly downhill. In comparison with the Grime Wizards, the Canis has a drastically extra rounded profile that actually exploits the completely different tread when driving within the flats and whereas taking sharp corners. Not like the Grime Wizard, or different beefy 27.5+ tires, the transition from the quick rolling centre tread to the aspect knobs isn’t all the time as predictable feeling as one would hope, and the few instances I caught myself daydreaming on tight turns, properly, I didn’t catch myself in any respect. Down I went.
I blame these unpredictable traits of the Canis on their light-weight casing, which at decrease pressures can buckle below the burden of a completely loaded bike. This was fairly obvious when driving tough terrain, or when the rear finish of my bike took massive hits when letting free on quick trails. My rear rim has made contact with the bottom extra instances than I’d prefer to admit, however the stable tubeless setup and common inventory wheelset have held up nice. There was some chatter within the feedback part on Spencer J Harding’s latest Maxxis Rekon+ evaluation, and it seems that there’s a consensus on heavier (+180lbs) riders avoiding light-weight casings. Is sensible to me, particularly when driving a mid-plus tire between 2.6” and a couple of.85” vast. Though, many of those experiences are purely situational, so contemplate your personal expertise first!

Oregon Timber Path Examined
A fast have a look at the tread sample will present that the Canis is made for low rolling resistance. The quite a few, intently spaced lugs are pretty shallow, particularly in the direction of the centre of the tire, creating a quick rolling strip that retains up velocity properly when driving at greater pressures or on laborious surfaces. Dropped to decrease pressures (12-17PSI), the aspect knobs offered extra cheap traction when cornering on virtually the entire terrain I’ve ridden on. The one instances I fully misplaced management of the tires have been when driving some extremely laborious packed singletrack (we’re speaking pavement like) combined with a skinny coat of granular dust, throughout one of many previous couple of descents alongside the Oregon Timber Path alongside Mitchell Ridge Path into Hood River. My driving companion, Ben, who was operating Maxxis Rekon 27.5+ tires, a considerably extra aggressive tire, had no drawback with traction by way of these sections. Throughout this part, and this one solely, I used to be undoubtedly lacking the aggressive claw-like traction of the Grime Wizards. It’s factor I used to be solely an hour or so from reaching Hood River.
In any other case, I used to be pleasantly stunned with the efficiency and total sturdiness of the Onza Canis’ each on the Oregon Timber Path, the Vapor Path, and a considerable quantity of different driving in Utah, Colorado, and Arizona over the previous few months. I’ve taken them by way of thick sand, grippy slickrock, loamy singletrack, and chunky descents with full confidence. The financial savings in weight, though comparatively small, was noticeable when driving unloaded, and I can’t argue with lightening up my base weight the place I can. I feel my success with these tires through the Oregon Timber Path – because it covers some demanding and assorted terrain – speaks loudly for what the Canis can deal with.
Lastly, I observed that the Canis wasn’t fairly as voluminous in comparison with different 27.5+ tires I’ve seen and used previously. It is a good reminder that not all 27.5 x 2.85” tires are created equal, and total measurement and form will all the time differ indirectly. For instance, Ben’s 27.5 x 2.80” Maxxis Rekons gave the impression to be barely bigger than the Canis. Though, the tread on the Rekons is much much less rounded and extra aggressive, so this seemingly performed a component in what simply could also be an phantasm. I undoubtedly observed a lower in measurement going from the 27.5 x three.zero” Surly Grime Wizards, which at first might have restricted my want to only roll over no matter obstacles lay in my path.
Seven months later, I’m nonetheless operating the Onza Canis tires as my main rubber and I’m pleased to report that they’re holding up nice. Though I’ve discovered myself commuting on pavement most days, a 31-mile journey in itself, the 27.5+ platform has confirmed extraordinarily versatile. The tires are certainly exhibiting some indicators of wear and tear, however that comes as no shock contemplating how a lot on-road driving I’ve put in over the previous few months in British Columbia. I’ve at the moment bought my eyes on a brand new 29er wheelset, one thing a bit lighter than the inventory Alex MD40 rims. I stay up for finally evaluating them to the 27.5 plus class, which is usually regarded as the end-all be-all of bikepacking wheels.
So, are the Onza Canis tires definitely worth the higher-than-average price ticket? I’m not solely positive. The numerous weight financial savings may imply they’re, and I’m fairly proud of how they carried out in a variety of circumstances. I at the moment have someplace round 1,000 miles on the pair I’ve been testing, and so they appear to be they’re holding up fairly properly. With a retail value of round $145 USD, they aren’t the most cost effective plus-sized 27.5 tire on the market by any means, however they’re one of many lightest. That’s about all I’ve to say about that!

It’s superior to see so many alternative plus-sized tires turning into accessible. Whether or not you might be on the hunt for one thing extra aggressive, much less aggressive, or maybe a bit bigger than the tires you might be at the moment utilizing, there’s something on the market. These transformed to 27.5+, a really unbelievable possibility for bikepacking, can actually begin to dial in a wheelset to enrich their driving type and the terrain. I don’t typically require the additional beefiness that the Grime Wizards present, so the Onza Canis’ low rolling resistance and lighter tread truly ended up suiting my driving tendencies a lot better. The assorted and intently spaced lugs of the Canis’ tread create a tire that may deal with a variety of circumstances, as I’ve seen first hand over the previous few months.
Though Onza is probably not the primary tire producer that involves thoughts right here in North America, I’m pleased to report that the Switzerland-based firm is making some prime quality tires that shouldn’t be ignored. On the very least, you’ll earn some road cred with the skinwalls. That’s, in the event that they’re nonetheless cool tomorrow…
