Theres little debate that in order to do some real Gravity racing, you need to have some serious nerve, some metaphoric balls. If you add the Vittoria Morsa rTNT G+ 27.5 Clincher Tire to your bomb-proof set-up, youll enjoy that extra jolt of confidence that knowing your hoops are wrapped in some serious rubber.

If you are casually glancing through the Vittoria MTB tire range, you may be wondering what the difference between the two different versions of the Morsa tires is. This rTNT version means that these Morsa come with a rigid, or wire bead. Using a wire bead instead of a folding bead will add strength and durability to the Gravity tire. Combined with the 120 TPI nylon casing, the rTNT Morsa offers both a high degree of wear and puncture resistance. The sidewall has also been given additional protection with a nylon fabric and abrasion-resistant rubber compound to check any chance of having your ride snapped short by an irreparable cut to the sides of the tire. The Morsa rTNT G+ 27.5 Clincher Tire come tubeless-ready. In fact, the TNT stands for Tubes, No Tubes, which will work perfectly with tire sealant when you want to go tubeless. The tubeless-ready bead core and sidewalls are made from Kevlar, ensuring the reliable durability, while the tire is shaped specifically to lock into the rim wall and provide an airtight seal.

Of course, superior grip in a variety of conditions, from wet to dry pack, from loam to gravel, is essential since you never know what the course will be like further down the hill. For that, Vittoria has incorporated their latest wonder material: Graphene. Graphene is a carbon compound two to eight atoms wide added to the rubber, which works to help reduce rolling resistance and weight while increasing durability and wet-weather grip. Add to that the Vittoria 4C layering process where they use four separate compounds layered through the tire and youll get the sort of grip and flex versatility that will be so essential in your downhilling. The 4C structure allows for separate base and surface compounds at both the center and side areas of the tread. This helps the tire to be tuned to different, even conflicting, performance characteristics when and where you need them: tread flex, rebound, grip, stability, etc.

These are beefy tires because they need to be. At 1300 grams in the 27.5×2.5, Vittoria Morsa rTNT G+ 27.5 Clincher Tire wont be the sort of thing youll look to for your more all-mountain enduro. But if you want to go downhill fast and secure in your treads, you could hardly do better.
