Introducing the CST Off-Road CM-EX01 140/80-18 70R TL — a purpose-built rear tire crafted for riders who demand confident grip on mixed terrain without sacrificing highway stability. Sized for 18-inch rear wheels, this tire is a true all-terrain performer designed to excel on adventure bikes that roam from forest trails to pavement.

• 
  Tubeless radial construction (TL) offers safer runs, easier repairs, and lighter weight on compatible rims, helping you stay confident on remote rides.
• 
  Optimized 140/80-18 profile provides a balanced footprint that supports predictable handling, steady feedback, and reliable traction across varied surfaces.
• 
  Rugged off-road tread with road-friendly stability features deep, interlocking blocks and tuned grooves that bite into dirt, gravel, and mud while delivering confident cornering and straight-line stability on asphalt.
• 
  Sturdy shoulder blocks and center rib for controlled grip in corners on loose terrain and even wear to maximize mileage on paved sections.
• 
  Puncture and heat resistance built into the casing helps resist common trailside hazards and manages heat buildup during extended mixed-terrain sessions.

Who this tire is for: riders who commute on paved roads but regularly venture onto gravel trails, dirt lanes, and light mud. It’s ideal for dual-sport and adventure bikes that need a versatile rear tire capable of handling long highway legs and spontaneous back-road explorations without changing tires mid-journey.

Why choose the CST CM-EX01 over other mixed-terrain options? It prioritizes a confident road feel without compromising off-road bite. The tread geometry is designed to maintain traction in wet and dusty conditions, while the tubeless design simplifies mounting and repair after a day of exploring rough terrain.

Practical tips for best results: ensure correct tire pressure per your bike’s manual for mixed-terrain use, inspect tread depth after long rides, and balance your wheel setup for even wear. For riders new to mixed-terrain riding, start with moderate pressures on dirt to maximize grip, then adjust based on terrain and load. The CM-EX01 is ready to become a dependable partner on your next adventure, delivering steady performance from the first twist of the throttle to the last mile home.
