Why We Like The Riddler TCS Light Tire

WTB's original 27.5in Riddler may be the ideal trail tire: cornering grip, straightaway speed, and a generous girth that provides comfort and grip without getting top floppy. The Riddler TCS Light Fast Clincher Tire imports those same characteristics to the gravel bike world. Its 45mm belly eats up gravel and washboard abuse while the molars on the shoulders bite into sloughy stuff and the low-profile, tightly packed center knobs maintain grippy speed across graded gravel. The compound follows suit, with WTB's dual-compound situating soft, grabby matter at the shoulders and harder, faster rubber over the center strip.

The Riddler is set up to run tubeless on any UST rim with the application of a sealant. While 23 and 25mm tires can actually gain weight when run tubeless, these burly donuts definitely benefit from ditching those huge tubes. Going tubeless also lets you lower the PSI, adding additional plushness when cushion and grip are at a premium. At this point in a description, we'd typically lay out a tire's limitations; with the Riddler 45, we're finding ourselves unable to do so. Bikepacking, gravel racing, all-terrain adventure cycling—the Riddler approaches any multi-surface scenario with gusto.

Will not hold air

These have hundreds of holes in the sidewalls and will not hold air. Both tires have the same issue. I'm returning these. 700x37 with orange seal

Manufacturing Defect in Sidewall

I returned this product before using it

Bought two tires and one was defective with small holes in the sidewall. Customer service was fantastic and offered a complete credit for the entire shipment. It sounds like WTB has had some quality control issues. Replaced with a set of Maxxis Rambler tires.

Great ride, questionable quality control

I've used it once or twice and have initial impressions

Out of the box these tires installed more easily than any other tubeless tires I've mounted, which was a big plus, but upon seating I noticed one of the tires had a series of perforations in the sidewall. Sealant was able to fill the holes and they seem to be holding air fine, but it makes me question their durability long term. Have taken them out on one 25mi mixed surface ride and they felt great. I just hope they hold up.

Corner Confidence & Way Smoother Ride

I've used it several times

The 700 x 45mm tires make my salsa warbird so much more comfortable to ride. Way less chatter in the washboards & I actually don't feel like I am going to die when braking or cornering in gravel. Just hit a 30 mile gravel race and they worked amazing from road, to washboards, to just plan fun fast and flowing gravel roads. Felt confident letting it rip even on steep gravel turns at high speed. The 2020 warbird came with terravali cannonballs 700x42and we did not get along.

Traction for miles

I've used it several times
Size Bought:
5' 9"

Great tire with plenty of traction on the dirt, while still being able to peddle efficiently on the pavement. I've taking it on everything from long gravel roads, to single track and back to pavement.
