Fake Schwalbe tyres?

[Chris S]

I saw a bike on Gumtree that had been fitted with Schwalbe 590mm tyres. The equivalent imperial size is 1 1/2" yet these have 1 3/8 on the sidewall. An established company such as Schwalbe should know the correct imperial size. Is it possible that these tyres are counterfeit copies?

Could be. Doesn't the writing usually be the other way up?

I would say that’s certainly fake. Counterfeiters will try their hand at anything.

Inform Schwalbe.. Maybe they'll send a couple of freebies

37 X 590 is 26 X 1 3/8" or 650A to the French and was the standard issue size on most British roadsters. You will also find that 622 X 37 are sized as 700 X 35c under the French system. Tyre sizes are rarely what they seem and many different standards exist.

There is nothing wrong with the sizing but whether or not the tyres are counterfeit, I cannot say.

There are only limited tyres available in 26 X 1 3/8" so do Schwalbe list that on their website for a start?

This. Never seen writing on any tyres, for any vehicle, that way up, and certainly not Schwalbes.

It was the '650' that confused me. I was only familiar with 650B tyres which are 584mm or 1 1/2".
26 x 1 3/8" is 650A, like you said.
