WTB Vulpine Tires: At The Finish

WTB Vulpine Tires: At The Finish – with Guitar Ted & Grannygear

The time has drawn nigh to wrap up the review of the WTB Vulpine 700 X 36mm tires. You can check out my second installment of the review here and there is a link from there to the first introductory post. Now I will be giving my final verdict on these new gravel tires from WTB. I also will be adding in comments from Grannygear, as WTB sent him a set to check out as well. So, we will get a bonus, “SoCal” viewpoint, and some awesome images to boot, if I may say so.

Okay, so with that out of the way, let’s get to it here…..

In this final review we get Grannygear’s take on the Vulpine as he used it in rural SoCal terrain.

Guitar Ted: In my summing up of the Vulpine in my mid-term report on these tires, I had this to say, “Paved surfaces are done with a fast roll, so if you mix paved and gravel roads on the same ride, this could be a tire that does it all for you.” Well, as we will soon see, this was really a big part of Grannygear’s riding with the Vulpine, but he also put this tire through some paces off-pavement which I think we will see are quite challenging. First though, let’s check in with Grannygear to see where his viewpoint is coming from on WTB tires in general and what his expectations are for gravel tires in general.

While the Vulpine looked a bit anemic, it outperforms expectations.

Grannygear: Up until now I would say that the only tire I really loved from WTB was the Resolute in the 42mm size. I did sample many of the other new tires as well, but none of them really clicked with me. Some of that was due to my priorities for a tire that works on pavement, hard dirt, rocks, sand, but not really in loose, deep gravel or mud. The Resolute rocks for me but is a big tire…43mms on a typical rim…and it’s more tire than a lot of folks need or maybe can fit onto their bikes. I love a bigger tire and I do not mind hauling it around even when it is not needed, as long as it rolls well (and the Resolute does roll really well). But less weight and less tire into the wind and less drag all around feels nice in a lot of situations. So a 35mm-38mm tire can be a smart choice, but looking down on the skinny Vulpine does give one a feeling of….well, inadequacy. 

Guitar Ted: Yeah! The “inadequate” comment was exactly my thought upon first looking down on the Vulpine when I first mounted these tires to my bike, but – as we shall see- that feeling soon is replaced with confidence.

Grannygear: I mounted the Vulpine on a rather narrow 19mm rim because the wheels were sitting around and were fast and lighter than most of my other gravel bike wheels. The Easton EA90SLs are really a road wheel now, with all the rush to wider rim profiles, but they still work fine. The Vulpines have settled into a true 36mm width on these hoops. Guitar Ted: This is a great point on the Vulpine. Its size really works well on those, now archaic, narrower road rim inner widths. I think if a person happens to have an older, tubeless compatible road wheel set, or older gravel wheels with narrow rim widths, this tire would be an ideal match for those wheels. That said, the Vulpine works great on 24-25mm inner rim widths as well.

Both Guitar Ted and Grannygear found that mud was no friend of the Vulpine.

Ride Performance: Grannygear: So…riding them. Fast. Fast. Fast! This is a fast rolling tire on anything with a hard and firm surface. Like pavement and fire roads. You might expect that by looking at them, but they have enough tread to hook up well on hard dirt surfaces. Braking, turning, accelerating…so far they have not scared me. I do have to tip toe a bit on the rocks but running a 43mm tire makes you a bit complacent. As long as I am prudent, these have been fine in rougher situations. Guitar Ted: I completely agree with Grannygear here. My only addition to his comments would be that due to the Vulpine’s lack of volume I find that it doesn’t have that stability in the fast, loose, deeper gravel we get out here a lot. I feel as though the size of the Vulpine is what slows it down in those situations versus a wider tire with more volume, like the Resolute Grannygear and I both like.

Grannygear: It’s been raining here in SO Cal a lot…a lot a lot a lot! So, my riding has been lots of road and dirt here and there as I could. But I knew I needed to get into more difficult terrain before I could say much about how the Vulpine handled those situations. I did have a few rides in techy areas while the dirt was still dry and I was quite surprised how well it did for a smaller volume tire, but I needed more.

“My kingdom for one more lower gear!” Grannygear putting the Vulpine to the test on a long dirt road climb.

On New Year’s day I did a ride with the guys on a local climb called ‘The Beast’. It’s a 3.5 mile ascent (with options to extend that) and climbs significantly in those 3.5 miles. It’s all dirt and ruts and rocky areas with, on this day, frozen earth and muddy sections. My first thought was “I have the wrong tires”. My second thought was “I need one more gear”!

But the Vulpine handled all of it just fine as long as I rode with some reserve. Yes, mud was not the best showing, but none of the other guy’s tires were doing much better in the tread-packing clay soils we have here. Yes, I had to ease into ruts with more care and I chose cleaner lines in the rocks, but I never felt sketchy.

And if I had ridden to the base of the climb on the road through town, it would have handled that too, and excelled on the pavement parts. It also turns with a very even and smooth response, not feeling like there is an odd transition off center like there was with the recent Kenda tires or even WTBs own Byway. Guitar Ted: Yeah, this Vulpine does not like wet soils! I agree 100% there. I also can concur with Grannygear here on how well this tire handles pavement. It can be leaned over and you can drill a corner pretty well. Much more so than with many other ‘gravel’ tread patterns I’ve tried.

Grannygear: I have been running 40psi most of the time and tried dropping to 35psi just to see. Unlike the Kendas, these Vulpines ride really well even at 40psi and at 35psi still rolled well on the road. I think 40psi for my 180 pounds is the go-to setting. Whatever WTB did with this cut resistant casing seemed to retain decent ride quality. Guitar Ted: Interesting! I have been running the Vulpine at something less than 40psi all along and I don’t think I’ve run it over 40psi ever. I weigh significantly more than Grannygear does, so this surprises me a bit in that I have had no issues with running these mid-30’s to upper 30’s psi air pressures. But then again, given the vert Grannygear has in SoCal, I may have had to bump pressures up a bit more over what I have to do here in the Mid-West for terrain.

At The Finish: Grannygear: Every so often you get a product to review that is so impressive, that works so well for you, that you wonder- ‘when it will let me down‘? I am still riding the new WTB Vulpine and I am still waiting for the let down. So far, so good. More than good actually. Like really good. Quite frankly, I love these tires. And the only thing I can think to make them better would be to give me a set in a 40-42mm size. Till then, this is a valid tire as long as the size and conditions where it excels rings true with you.

While we would like to see a larger volume Vulpine in the future, these tires are staying on our bikes for now.

Guitar Ted: What he said! This tire is kind of an oddball in WTB’s line up. The other SG2 cut protected tires I’ve tried are good, but this Vulpine is so much nicer riding that it boggles my mind to think that it has SG2 cut protection in there. The Vulpine is- by far– WTB’s best riding tire for gravel yet. The Resolute with no cut protection is pretty good as well, but somehow the Vulpine is smoother riding. Okay, maybe that 650B Horizon is smoother, but- that’s a different tire altogether. The point here is that the Vulpine is a very impressive tire from a ride quality standpoint. It is an impressive tire from a performance standpoint in that it can handle a wide range of surfaces- as long as they are dry! The Vulpine is a tire that makes you think, “What if this were available in a wider size?

And that, dear readers, is probably our only negative in regard to this tire. There are times where you just have to have that volume, and the Vulpine’s 36mm can only go so far. But that 36mm covers a lot more territory than you might think, and really, it may be all you’ll ever need. I know Grannygear and I won’t be taking these tires off anytime soon.

7 thoughts on “WTB Vulpine Tires: At The Finish

  1. Any thoughts on comparing it to the WTB Riddler in 37mm? My bike has limited clearance in the rear, and the Riddler just about fits (on a 19mm rim); I have been quite happy with it, other than its pretty fast wear rate. From your review it sounds like the Vulpine might be a compelling alternative for slightly more demanding terrain?

  2. @BB – I believe the new Vulpine rides a lot smoother and “smoothness” usually is a result of a tire casing that is faster and of higher quality. The 37mm Riddler always seemed a bit stiff and dead to me. I think you would be pleased with the Vulpine just from the rider quality aspect alone.

  3. When they were mounted on a wider internal width rim, did the grow above the 36 in width? Have a bike, like the other poster where it’s tight behind on a 21 internal width rim. If they stayed at 36, I might be able to squeeze them in, lol.

    Currently running a 700×33 Clemente mxp that has grown to 36.5, and is a tight fit. Bike doesn’t see a lot of gravel miles, cause my gravel is generally too loose and sandy to be much fun with skinny tires. But, this could definitely give the bike more options, particularly when it’s so fast on pavement. Thanks.

    1. @Tracey – Maybe a little bit, but the SG2 casing doesn’t stretch much, so as I recall I only ever saw about 37.5 -ish mm on a wide rim. The wider rim will definitely make the tire profile widen out a touch and your “tight fit at 36.5mm” could be exceeded with this Vulpine.

      Keep in mind air pressure has a big influence here also. The higher you go in psi, the wider the tire will get. to a degree, and every tire responds differently to that, but in general, you’ll find that to be true with tubeless tires especially.

  4. I’ve ridden the Vulpine 700×36 tire tubeless for 400 miles. Tread life good. Good for light gravel. Anything rutty rocky single track, the tire is weak. Sidewalls easily ripped. 6/10 if you ride anything other than gravel or road.

  5. I picked up a pair with 700×40 as nominated width. I wanted a faster tyre vs my 650 x 47 Hutchinsons. These tyres mounted easily even without a rubbery bead. They have a fine casing and no excess rubber anywhere. My tyres measured 38mm even after a week. Perhaps they might stretch after a few hundred km that im putting into them. I too am absolutely delighted and utterly impressed by these tyres. I run the front at 35 and rear 40. I weigh 80kg + say 7kg of bags and kit. These things are so subtle and FAST! The speed is the most noticeable aspect then the noise. They are very noisy on tarmac. The grip they offer is excellent, cornering is a little spooky initially as they feel a tad floaty but once you get used to that they hook up great. They are perfectly suited to gravel and asphalt mix but you can take them on more tech trails. Given the subtle casing I don’t feel confident to bomb them through rocks but after 240km of mixed riding including some rocky stuff no issues. I would pick these over byways etc which were the fastest rolling wtb I have tried. These are superior to the vittoria terreno dry ( a fast tyre in 38mm) in every way except noise. Highly recommend .
