Exposure Road TCS Tire
If you find that your drop bar rides are starting to involve hitting miles of decent tarmac before getting out to seldom-used chip seal and gravel roads, check out WTB's line of Exposure tires. Using technology that's proven itself time and time again on its off-road tires, you can enjoy renowned WTB durability knowing these tires will roll fast like a premium road tire while holding up when venturing off the beaten path. Available in three widths, 30, 32, and 34mm, the center section features a smooth tread and as the tire gets wider, the side knobs become beefier for better cornering in loose conditions. Oh, and did we mention that these versions come in awesome tan sidewalls?
For its tubeless, Supple casing, WTB uses a multilayered construction offering a smooth ride that increases traction and it's durable in rough conditions. The TCS aramid bead makes for a super easy tubeless setup and running a bit of sealant inside helps prevent goatheads, sharp flints, and broken glass from ruining your ride. The tires are capped with its Distance + rubber compound that's both grippy and long-lasting. These tires are ideal for those days where your route isn't always determined and the riding surface offers enough variety to keep things interesting.

- Q & A
- Familiarity: I've used it several times
Similar to a prior reviewer, a pair of these also came on my Cannondale Synapse. Tubes were installed and at 80 psi both tires mike out near 33 mm, and they're 30's. To get the tires to fully seat on the rims, an air compressor works best. I did use my frame pump to seat the tires to make sure it was possible in the field. It took over 200 pump strokes and pressure at the max tire rating to get the beads to seat (tire pressure rating is 60 to 90 psi). Since the tires and rims (also WTB) are both tubeless ready, I purchased a pint of Stan's sealant and went for it. The tires would loose 20 to 30 psi over night, riding the tires didn't help them seal any quicker. I ended up purchasing a set of Mavic UST rims from Competitive Cyclist; Mavic included their tubeless tires and sealant with the rims, along with a sealant syringe. Tested installation of the Mavic's with the frame pump, seated easily under much lower pressure. The Mavic tires with sealant sealed without issue, pressure drop is just slightly more than tubed tires. With the WTB tires set aside for a few months pressure dropped to zero. I added more sealant and they are now holding pressure, with about 5 ounces of sealant each tire. I put them back on the bike and they perform adequately, though they look like balloon tires on there. I run them at 70 to 75 psi tubeless and they are still wide (32.6 to 32.9 mm). On damp surfaces they tend to slide when hard braking (unintentional). I'll continue riding these until worn (or I don't trust them) and research true tubeless tires as replacement, I like to have a second wheelset for my bikes. One take away, I'm sold on tubeless for road bikes.
Loving these with or without tubes!

A pair of these came on my Cannondale Synapse. 3800 miles later, I still love them. They're wonderful both on and off pavement running 40-50psi while tubeless on my 21mm WTB KOM TCS rims.
