WTB Thickslick Tire (Black) (Wire) (26" / 559 ISO) (2.0") (Comp)

It’s all in the name, ThickSlick. Made with a burly casing designed to withstand the roughest urban conditions, while the no-nonsense, slick design provides the bite you need in the concrete jungle. Need more rubber? The nearly indestructible Flat Guard level, with its Urban Armor Casing and added rubber...everywhere, provides optimal protection to contend with any city streets. It's no wonder why this tire has a cult following among couriers, those not wanting to deal with flats, and value-conscious consumers.


  • Puncture Protection:  The thicker a tire, the harder it is for glass, pins, staples, and other urban unpleasantries to worm their way in. 
  • 2X the Rubber: Twice the rubber tread equates to twice the lifespan of a tire. This means your price is 50% off the competition. 
  • Smoother Ride Quality: Twice the rubber makes for a smoother ride through the natural absorption qualities of rubber
  • Comp: Base-level Thickslick tire provides value, protection, and durability
  • Flat Guard: Adds a layer of thickness to prevent against pinch flats and punctures

WTB Thickslick Tire (Black) (Wire) (700c / 622 ISO) (25mm) (Comp)
After a few months of not too heavy use, my ThickSlick Elite 700x28c (with "Urban Armor Casing") developed long cracks (splits) along the sidewall.

In all fairness, I purchased these (from Performance Bicycle) a few years ago and kept them (in the house, not out in the garage) for future use. But I saw no evidence of any issues when I mounted this tire on the wheel.

After only about 1000 miles, tire side walls bulged outwards, and had to be replaced. Poor quality.

Currently using a WTB Thickslick on a moped build, and it seems to be holding up. The rubber is hard, durable, seems to grip well.
