Your scooter/power chair handbook may show the tyre size. However this may be shown as an overall dimension of the tyre such as 12". Therefore always check what is written on the tyre itself.

All tyres have a size marking on the sidewall of the tyre but the way it is shown does vary between manufacturers and may show two or three markings. Some of these are shown in the table below. When you have a note of all the sizes listed on the tyre, you should be able to find the correct tyre in the relevant categories.

Tyre Size	Alternative Size
200 x 50	8 x 2
300 x 4	260 x 85 or 10 x 3
400 x 5	330 x 100
20 x 1 3/8	37-451
22 x 1 3/8	37-501
24 x 1 3/8	37-540
24 x 1	25-540
25 x 1	20-559
26 x 1	25-590

The next thing to decide is the Tyre Tread Pattern. This is fairly easy and you should be able to match the pattern you have with the pictures on the web site. As a rule of thumb a ribbed (lined) pattern tyre fits the front wheels and a block (chunky) pattern fits the rear wheels. Some scooters have the same tread pattern on both the front and rear. In this instance it would be a block pattern.

The final thing to decide is the tyre Colour. Grey tyres are normally fitted as they are non marking but black are also available. If you decide to order black please be aware that they will mark floors and carpets if used indoors.
