Designed to prowl the backcountry, the WeirWolf is the go-to choice for extreme trail riding. Fast rolling center knobs keep pedaling efficient while the razor-like cornering knobs grab the trail (and shake it up like a fuzzy bunny).

Strengths:    Great Grip. Nice 2.1 size(not bigger or smaller than the stated size), Cool looking, Race version is light

Weaknesses:    Good as a front tire, but there might be better choices.

Bottom Line:   
These tires climb excellent and descend almost as good too! Great dry conditions tire(which is 90% of SoCal riding). I really really like it as a rear tire. As a front it is good too, but I do feel it slipping once in a while(other tires would probably slip just the same or worse). The good thing about the weirdwolfs, as others have said, is that they lose traction predictably and give you a chance to regain it instead of just washing you out completely. I am going to try another tire on the front when these wear out, but will most likely keep the weirwolf as a rear. I might even go for just a wider WTB brand front tire since I'm so impressed.

My rating:
4 Chilis for value because they aren't cheap tires
5 Chilis for overall performance

Strengths:    Excellent dry conditions tire. Less rounded profile than most other tires, so you don't have to lean it as far to get into the side knobs (cornering knobs). I have the non tubeless race version which is pretty lightweight. It spins up and rolls pretty well. Braking is first class. It holds your chosen line very very well, and tends not to push off the trail like other tires. It wears pretty good, too.

Weaknesses:    This is not, I repeat this is not a tire to use if the trails are anything other than dry. It does not clean at all. It will pack up and hold onto mud with a death grip. Mud crossings on an otherwise dry trail cause it pack up, and make it slick.

Bottom Line:   
This is one of the very best dry conditions tires out there. Because it is so good in the dry, it is poor to dangerous in the wet. That said, the 2.1 Race version is lightweight, spins up well, rolls really well, enters and climbs out of hyper-steep creek entrances with the best. It has a less roundy profile so you don't have to lean very far to start getting into the corner knobs. IT brakes extremely well. It holds a line very very well. Some tires lose traction and washout on you. Traction is there, and then in an instant it is not there. When this tire loses traction it does so very slowly, and gives you time to react, and correct.

Again, all this applies to dry conditions. If the tire will pick up mud on the ride, make another choice (I use Continental Explorers for that).

Submitted by sburnett a Cross Country Rider from FTW, TX

Date Reviewed: September 11, 2011

Strengths:    I have run these Front and Rear -
Rear - This tire grips incredibly, the only time I have had trouble is when taking steep climbs out of saddle in sandy stuff. It grabs and grabs on everything else I have used it on.
Front - The tire has slipped out on me once, during a night ride at a section of trail that was chewed up. I was likely going to fast. I would recommend it. Though a slightly larger tire is better. I recently replaced the front with a WTB Stout 2.3 and the combination of Weirwolf rear and that front is amazing. I will never run a different setup.


Weaknesses:    I had the front tire sidewall shred on me one day riding on pavement. I can only assume that something got inbetween it and the rim. The rear tire has given no issue.

Bottom Line:   
These tires are awesome at the price I got, I always scoop up tires with good reviews when they hit Chain Love, I would pay up to 30 bucks for one of these, and that is a lot considering I have never paid over 16 bucks for 60+ dollar tires.
They are great, if you see a deal, GET IT.

Strengths:    Grip and corner well, shed mud well, great looking tire.

Weaknesses:    Quite expensive.

Bottom Line:   
I have been riding the Bontrager Jones that came stock on my Fuel for 2 years, until realizing that these were uber crap.

So I decided to try the 2011 Weirworlf 2.1 on Front after "shopping" on mtbr.com the best tire that would fit my riding. I use it mostly in humid conidtions during spring and autumn and very dry conditions during summer, and I must say that this tire grips very well even at high speed. It certainly helped boosting my confidence in those turns. It also does not slip too much on wet roots/rocks.

Its only downside is his price here in Canada. I had to pay around 65$ for only one tire.

Overall, it's a very good tire and I would recommand it.

Date Reviewed: February 9, 2011

Strengths:    This Review is for the New 2010 WTB Weirwolf XC TCS tire with the terraced side nobs. I ran the same tire in both front and rear, and I must say I have never ridden a tire that feels this amazing. In any trail condition, this tire will help you fly. The terraced side nobs will change the tire industry as we know it. The side nobs allow you to roll over and actually 'feel' the drifting effect depending on how hard you dig into turns- Very similar to holding an edge on a ski/snowboard. It takes a while to get used to, but eventually you will build up enough confidence that you will easily be able to get that two-wheel drift into turns without having to put a foot down. Then, when you finally start to feel your bike slide out from under you, you can really dig the edge in and slingshot out of turns.

Weaknesses:    Price point - for the weight of these tires, its hard to pay 120 bucks for a pair.
The learning curve - At first, these tires are very skiddish and squirelly and I washed out numerous times on the simplest high-speed turns. But after a few rides and figuring out how to use them properly, I have absolutely no complaints and would recommend this tire to anyone from recreational to racing.


Bottom Line:   
These tires are just pure fun. If you like skiing/snowboarding, then you will absolutely love these tires because they simulate holding an edge in snow. I was always skiddish and sloppy when it came to drifting//high speed turns with other tires, but as soon as I got passed the learning curve on these weirwolves, I have become much, MUCH more confident in turns: 2 wheel drifting, then catching that edge and slingshotting out of turns with ease.

The bottom line is I have never had this much fun on a bike. These tires will make you more confident, faster, make you hit turns harder, and will give you an incredible euphoria on the exit of every turn.

Date Reviewed: October 6, 2010

Strengths:    They look good and get good reviews

Weaknesses:    Squirrely

Bottom Line:   
My bike came with Kenda Nevagals on it great XC tire, I ride on the road a fair amount and installed Panaracer Mach SS and SK's great tires much faster and very low rolling resistance. I was anticipating a longer XC ride and having a cut in the tread of my SK I opted for a more agressive tire for the upcoming ride. Installed the Weirwolf tires and hit the road, I got on the binders on the first corner, felt like I was on bristles, no bite on pavement, rolling resistance was high and wieght noticable. Thought I would put up with it if the tires were that much better off road. Hit the trail (hardpack) and the tires were much worse than the SS/SK combo again hitting the brakes in turns as the tire would not hook up and a felt I would just drift out of the corner.

I weigh 200LBS and had the pressure up to near 50 PSI on these, lowering the pressure may help the handling but, will also increase the rolling resistance. Maybe when the knobs are worn down a bit they will start to bite but, for now I am not brave enough to ride these guys fast on or off the road. On the pavement there were corners I could fly through at 40 on the Panaracers or Nevagals that I was uncomfortable in at 30 on the Weirwolf. Mybe I need to wait for a full moon.

These guys are coming off and the Panaracers are going back on.

Date Reviewed: August 29, 2010

Strengths:    I have had these tires for over two years and still have a great amount of tread left , I ride on pebble rocky trails to pavement trails and streets. I haven't had one flat or repair..

Weaknesses:    At low pressure the sidewalls seem to slip and grooves on the sidewall (similiar to a dragster tire with low pressure,off the line).rolling resistences

Bottom Line:   
This are the wire bead version, I would suggest these tires to anyone thats looking for a decent set of tires, yes there little bit on the heavy side but if you get 3-4 summers out of a tire and it still looks like you just bought them tread wise , and no flats or any problems what so ever.. last thing I want to do is be stranded on side of a trail changing tubes or spend my time at the shop buying tube instead of riding, after a day of riding and cleaning up the bike with Pedro's bike lust on frame and tires really makes the tires stand out ..

I wanted to switch up my ignitors seeing as they didnt really excell at any one particular factor. I went out and baught some small block eights, super light, but horrible in any mildly wet conditions and i just didnt feel comfortable turning at high speed with them. SO i put my ignitors back on they were much better all around tires. I saw these tires the new VERSION and baught ALL I CAN SAY IS WOW combine the speed of the small blocks with the grip of the high rollers these thing are simply amazing front and back. MY first ride out i was pushing into new boundaries of turning angles. THANK YOU WTB

Strengths:    These tires grip the crap out of the clay/sand soil we have here in Louisiana. Small gravel was no problem. Mud was no problem.

Weaknesses:    None so far.

Bottom Line:   
I'm a noob and I thought my technique was most of my problems with riding. I replaced the stock Bontrager Jones XR after reading the other horrible reviews on here. I bought those bad boys and my riding confidence has been boosted. I can now rip through curves and climb inclines like a billy goat. Also, I love that they shed the mud quickly without covering me in mud. The Bontragers used to cover me. These tires rock!!!

Submitted by Gloopy4444 a Racer from Phoenix Arizona USA

Date Reviewed: April 21, 2010

Strengths:    This review is of the 2010 Weirwolf Race 2.1 tire. Used it front and rear, tubeless, using sealant. WTB has improved this tire over the older model. It does not throw rocks nearly as much and seems to roll a good bit faster. As with the older model the traction is still quite good. The tire does well in the sand and sheds mud well. I run them around 25 psi. Probably have 150 miles on them so far.

Weaknesses:    Weight, but with all those knobs its no wonder. Mine were 722grams, -- heaver than advertised. Durability might be an issue. I got hole between side knobs and the main knobs while riding up over some rocks in Fruita. The hole was large enough that sealant sprayed out and never sealed the hole. The tire was 20 miles old. I have since patched the tire and have not had another issue. Could have been a freak thing.

Bottom Line:   
I believe WTB has improved this tire considerably over the older model. One of my big complaints with the previous model was the weight, I had a old UST Weirwolf tire that was close to 850 grams, this tire seems lighter. My other real complaint was that the older model picked up and threw rocks constantly. I'd get hit in the face with rocks. The new tire doesn't. The tire has good cornering and off camber grip like the original. I think the tire profile might be a tad more rounded, so the cornering is more predictable over the range of lean angles. Finally, I think that WTB may have softened the rubber compound over the original, they seem to be wearing a bit faster.
