Sometimes it's okay to get fat...like with your mountain bike tires. The Nashbar Grinder Mountain Tire has some of the chunkiest, fattest, most aggressive tread we've ever encountered here. If you're all about tacking on some super-steep, rocky, root-laden trails, this all mountain, all weather tire delivers the goods. Get ready for trail grabbing like never before.
30 TPI is supple for excellent lower-pressure traction
