A wheel-size number is only part of the setup. Tire construction, pressure, suspension and the rider's load also affect how the scooter feels.
Start with the model.
The S1 Max has 8-inch solid tires. The G2 Pro has 9-inch tires. Several G2 models use 10-inch tires, and the G4 uses 11-inch tires. The X1 dirt bike has a 14-inch front and 12-inch rear wheel.
Check the tire construction.
Solid, tubed and tubeless tires have different maintenance needs. Match a replacement to the exact wheel and listed size; diameter alone is not enough.
Compare the whole ride.
A larger tire does not replace a useful suspension and brake setup. Check all three, then consider the weight and folded size you will handle between rides.
