Some scooters use inflatable tires like bicycles. While these tires can absorb bumps and create a smoother ride, they can also puncture. Unlike bikes this is a significant safety issue as the tires are so small they can easily get stuck and lead to falling forward. Inflatable tires also require more maintenance.
These problems can be avoided by solid rubber tires. These near indestructible tires offer a safe and maintenance free solution, at the cost of a slightly bumpier ride.
