I think it is safe to say that mud tires can be a hotly contested product based on locale, and how well trails get along with mountain bikers during the wet months. Many ecosystems have trails that when muddy, simply aren’t rideable without damaging what local mountain bike groups have toiled endlessly to build. There are places however that have trails that fare extremely well, allowing water to sheet straight off, and prevent single track from becoming laden with mud. I say this to prevent people from getting hung up on the fact that mud tires are available at all, as some trails may never see a dry day. Just because Ritchey offers a mud tire doesn’t mean you should go out an tear up your local trails, but if you routinely ride in the wet, this review is for you.
Around my neck of the woods, we definitely fall into the former category, with the worst soupy, clay filled mess this time of year that causes most of us to give up on mountain biking until April, or, at worst, June. Mother Nature routinely plays cruel jokes on us with stretches of sunny 70 degree weather, followed with torrential rains, and it repeats. The trails rarely dry enough to ride without a bit of shame, so finding suitable trails to test the ZMax tires was tough, so the all of the riding was done on double track, and a relatively unknown trail that I have spent a lot of time personally building and keeping up.
After only two rides my mind was made up. Why? Find out after the break!
As I initially reported on when I took the ZMax Grips out of the box for the first time, the Grips are narrow. I know that mud tires are historically narrower than their dry counterparts, so I was expecting them to be slightly smaller, but I was surprised when I inflated them for the first time. Obviously, the tire is marked a 2.0 so it should be narrow, though in reality the ZMax barely eked out a 1.9 when mounted up tubeless to a DT Swiss 1800 rim. Narrow mud tires help to penetrate through deep mud to find traction, and help with tire clearance when things really start packing up. On the flipside, narrow tires can be more squirrely and less sure footed than larger offerings. While I was slightly disappointed in their actual size, I was not disappointed in how they seated up tubeless. Hand pump, floor pump, doesn’t matter, what ever you are using you should have no difficulty getting the Ritcheys to seal even if you don’t have an air compressor. Of course, this means that the tires are a royal pain to get on the rim, but it’s that tight seal that allows for easy inflation by hand.
The ZMax Grips are currently a 26″ only model, and are offered only in the 26×2.0 size. I tested the ZMax Grip 2.0 WCS edition which retails for $59.95, but the tire is also offered in a cheaper Comp model which retails for $29.95 and weighs 100 grams more than the WCS.
The ZMax is light which is no surprise considering its size and the fact that it is tubeless ready. As UST tires are typically much heavier, tubeless ready allows for a light tire that can still be run with a tube, or run tubeless as long as you use a sealant. While running the ZMax Grips I used my go-to sealant, Stan’s Tire sealant, which I have had great luck with many tires sealing anything from thorn punctures, to large cuts, to light sidewall tears (notice the foreboding?). When I set out to test the ZMax grips, as mud tires, I was looking for 5 things: mud shedding, penetration through deep mud to find traction, grip over greasy roots and rocks, durability, and all around confidence on the trail. When I say that I typically don’t ride a lot in the rain, it isn’t for lack of skill or desire. In fact, I feel that I’m pretty good in the wet (as long as I have the right clothes, right Tyler?).
