Michelin Force XC Competition Outer Tire Michelin Force XC Competition MTB tires are extremely well suited for dry grass and forest surfaces. The widely spaced knobs keep your tires clean during the ride so that you maintain maximum grip. The Michelin Force XC Competition MTB tires have higher knobs next to the tread for optimal grip in corners and to maintain control over your mountain bike. The Michelin Force XC Competition is supple, durable and puncture-resistant thanks to a 3 x 110 TPI carcass.
