Can I put bigger wheels on my mobility scooter?

Just so, can I put bigger tires on my scooter?

You want more speed, well then you want a taller tire (larger overall diameter). However, you'll sacrifice acceleration, which can be a little to a lot depending on how much taller you use. With most scooters, you can't get much taller in diameter of your tire because it will rub the engine case, in most cases.

Similarly, how do you inflate mobility scooter Tyres? The best method of inflating an mobility tyre is to use a regular foot pump or a cycle track pump (A hand pump is fine too). You'll find the valve type is either a Schrader or a Presta valve. Once you know which you need you can simply setup the pump attachment, fit it on and away you go getting your pump on.

In this manner, what is the TYRE pressure on a mobility scooter?

approximately 18-24 pounds per square inch

Why are scooter wheels so small?

Well, the same applies to scooter wheels. Small wheels transmit bumps and jolts to the rider much more severely than larger ones do. The larger the wheel the larger an object it can roll over without ill effect. Smaller wheels do offer poorer handling than larger wheels do, however.
