Wheel Sizes

Just got a bike for my o/h, it needs new front tyres. Now the tyres that are on there are marked 37-451 (20" x 1 3/8). Would a tyre marked 406 (20" 1.35") fit, or do I need to get tyres marked 451?

Sounds like a shopper. The tyres you are suggesting would be fine.

Its another recumbent

If the tyres that are coming off the bent are 451's, then 406's won't fit as they are smaller.
You need new 451 tyres.

You will also need Schwalbe AV7A innertubes, not the plain AV7's

Bugger. That's what I thought.
