12 inches ?

[DaveReading]

Not strictly a bike question, I've been tasked with fixing punctures on two out of the three wheels on the grandkids' stroller.

Tyres are marked 12½" x 2¼" and the replacement tubes from most sources are in the £5-£10 range, which seems extortionate.

On the other hand, Decathlon do 12" x 1.7-2.2" tubes for £1.99 (with an angled valve, too, which is a bonus). Would these do ?

2.25 would be 2 .1/4 so I'd guess so.
2.2 is so close I wouldn't be concerned.

 

[ColinJ]

Yes, but I don't use it as a rule!

Oh, sorry, you weren't looking for smutty jokes ...

The sizes do sound close enough to work; rubber inner tubes are pretty stretchy!

 

[fossyant]

Go for the decathlon ones.

Yes, they'll probably be exactly the same ETRTO. A 12" wheel is a 12.5" wheel, it's just less convenient to talk about a "twelve-and-a-half-inch" tyre than a twelve

 

[I like Skol]

Why not just get a puncture repair kit from Wilkos for a quid and fix the existing tubes?

Because the current tubes have straight valves, and on the small wheels they're a PITA to get a pump on them.

At £2 each, a set of new tubes with angled valves (now that I'm reassured they will fit) is a no-brainer.
