Tire Ø 90 mm

This is the perfect fit for my build—the 90 mm diameter rolls smoothly with zero wobble. The hard plastic feels durable enough for my indoor track, and the axle hole lined up exactly with my existing setup.

Was worried a 90 mm would be too chunky for my build, but it rolls surprisingly smooth on the tile. The rubber has a nice firm grip and it feels sturdier than the plastic ones I've used before.

Snapped right onto my old kit without any wobble, and the rubber has a nice grip to it. Finding a single 90 mm spare instead of buying a whole set was exactly what I needed.
