Bontrager G-Spike Team Issue MTB Tire

No, these are specialized mud tires. The aggressive, tall spikes are designed to penetrate soft, wet, or muddy ground, and they will feel sluggish and unstable on hard-packed dirt or rock.

Yes, the spikes are designed to be trimmed. Many riders customize the tread height using side cutters to better suit specific soil conditions or to reduce rolling resistance on slightly firmer terrain.

This tire uses a wire bead and is designed as a traditional clincher. While some riders attempt tubeless setups with wire bead tires, it is not officially rated as Tubeless Ready, so you should plan to use it with an inner tube.

At 1275 grams, this is a heavy-duty tire. It prioritizes puncture protection and casing stability for downhill racing over weight savings, so you will definitely notice the extra rotational mass compared to a standard trail tire.

It features a robust dual-ply casing reinforced with an additional butyl layer. This construction is specifically engineered to resist pinch flats and sidewall cuts during aggressive downhill riding.

The 42a rating refers to the durometer, or hardness, of the rubber. This is a very soft, tacky compound designed to conform to the ground and provide maximum grip in slippery conditions, though it will wear down faster than harder rubber compounds.
