Gravel Thundero A universal tire for those who don’t want to think about where to go. The Thundero can do it all. The middle part of the tread, composed of tightly packed cubes, creates speed and surprisingly quiet rolling with three indented rows of knobs on the outer tread, which bite literally into any surface. This provides excellent grip even on unpaved surfaces and allows you to turn sharply. The wide tread and the durable flexible Jubena layer covering the sidewalls protect the tire from receiving damage from stones. A Puncture proof ply under the tread minimizes the risk of punctures and contributes to the overall reliability of the tire. The high TPI casing construction, together with the soft tread compound, smooths out any surface and prevents the tire from bouncing on uneven surfaces. The Thundero is also made to be long lasting and guarantees high mileage. 700 x 36 all black 700 x 40 all black 390 / 430 grams / 30-70 psi
