WTB Resolute Gravel Bike Tire, Tubeless Ready Folding Bead, Lightweight Fast Rolling, Mud Shedding, SG2 Puncture Protection for Gravel & Cyclocross

Mounted the tire on DT Swiss 24 mm inner width rim. Inflated tire measures 43 mm from sidewall to sidewall (the knobs are a bit wider). Trick for success is to install a perfect tape, then coat the rim with sealant, especially on the clinchers sides. Install tire, inject sealant, inflate. At around 35 psi the tire popped into place, pump to 50 psi and let sealant cure. Wipe off messy sealant from sidewalls and rim. A few hours later, reduce pressure down to 32 psi and ready to go. Nice and fast rolling, behaves well on trail.Update: tested today on a challenging gravel race that included tarmac, 20% grade uphill single track, large chunky sharp railroad ballast and smooth trail gravel. I rode mostly alone, so no drafting and was able to do 20 mph on flat road and 16 mph on flat smooth gravel, so they roll pretty fast. I went as hard as I could on single track with roots and rocks and on the rail road ballast and the tire just kept going and didn’t even lose pressure. On the segments I was able to ride the 20% grade single track it didn’t really well without skidding in semi dry dirt but it did skid on the part of the trail that was covered in leaves.Update: after using them for a couple of weeks they stretched out to measure at 45 mm wide on 24 mm internal rim. Nominal width is 42 mm. I installed it as my front tire on the Canyon Grail.

Replaced my worn Vittoria Dry 38mm tires with these. While I did love the Vittoria tires, and was open to replace them, I figured I’d try a fatter tire with greater tread this time, to see how they’d hold up to the hilly potholed streets of DC. These are holding up like a champ. Super grip and performance on messy bumpy streets and off-road of course, and much faster than I expected them to be at 42mm, even on tarmac, relative to my old 38mm’s. I will be buying more of these, as spare backups.

Really like the tread and performance in both loose/muddy conditions and hard pack. The deal breaker is after only a few months of use, either via bad luck or poor quality casing, the tire punctured near the center and would only spew sealant like a fountain. No actual seal. I could have used a plug (if I had one). But lost faith in the product and decided to abandon ship on the spot (I was blocks from a my bike shop) and go back to the Specialized Pathfinder Pro. I've run Pathfinder several other tires each for about a couple of thousand miles or more each and never had this issue. Again, might have just been random puncture, but it was my first flat in three years of gravel riding. And the Stans was fresh and plentiful in the tire.

Awesome tires, big upgrade from Gravelking Sk. Cushy, burly, very predictable handling on my first 50mi hardpack and rocky ride. Fast enough and quiet on asphalt. Had one major rock edge hit that I thought might put a gash in them, but tires held well. Measured almost 43mm after 48hrs on 23mm id stans grail cb7 rims. Weighed 516 and 520 gm. Really liked these tires, changed the feel of my bike and gave me more confidence. This is after about 550mi with 38 (40mm) GK SK tires, which may be slightly faster on the road but these WTB beat them in every other way, and I didn’t notice the weight gain.

These tires leak sealant through the sidewalls so badly that I can't understand how WTB can claim they are tubeless. It's like there are hundreds of pinholes through the tire sidewalls, on each side they just constantly bubble and never seal. They lose all pressure in a few hours of sitting idle.To top it all offs these sg2 puncture reinforced models punctured on literally my first ride less than 5 miles in on my local trails that I've never punctured on with any other tire brand. The puncture was tiny, and sealant wasn't plugging it. Required a dynaplug, and even then it's not plugging.I've been riding tubeless setups for years and this is the most embarrassing "tubeless ready" tire I've ever seen.The only reason I'm giving this 2 stars is because the grip is amazing, until you puncture. Bring a hand pump because they leak so much air you have to top off mid ride.I'll give them some more time to properly seal over the next couple weeks and if so then I'll update my review. As it stands after first impressions, can't recommend them.

Just not cutting it…or actually getting cut too often. Have had 4 of these tires and can’t seem to go three rides without a puncture. I may be running a little higher on PSI, but tires just not holding up.

Riden once with the tires feel good and roll nicely over different terrain.

Tubeless scellant leak thru the sidewalk all around the tire. It is unusable. Tried with Stan’s scellant. Never had any problems with my maxxis tires.
