Inner Tube Size Help

Sizing Inner Tubes

Sizing inner tubes is pretty much the same as sizing tyres, the size you need is often printed on your existing inner tube. (See image below) If not, just look on the sidewall of your tyre and the numbers on the wall of the tyre will be the inner tube size you need also.




Common sizes:

12 ½ x 1.75 x 2 ¼ (47-203) Mostly found on Phil & Teds.
12 ½ x 2 ¼ (57-203) or (62-203) or (65-203) Very common size on prams.
270 x 47-203 Mostly found on Jane prams.
280 x 65-203 Any of of 12 ½ x 2 14 tubes fit this size.
300 x 55 Mostly Found on Phil & Teds Vibe, Verve and Smart Lux.
10 x 1.75/2 (47-152) Often used in the smaller front wheel of 3 wheelers.
10 x 2 (54-152) Often used in the smaller front wheel of 3 wheelers.
200 x 50 – Very small often used in small double wheels at the front.
8 ½ x 2 - Not so common on prams but not unheard of.

Valve Types

We sell all our pram tyre and tube sets / pram tubes with angled valves (See images) for easy access with a pump, some sets sold online are listed with straight valve inner tubes because they're cheaper. Problem is that you can't often get a pump on them to inflate on such small wheels. Jogger puschairs with 14" or 16" wheel only come in straight valve as standard. (No need for an angled valve on larger wheels).
