I have just got my self a vintage Raleigh mini velo witch runs 24" inch wheels for my son. But the problem we have is that it need some new rims and tyres..

I have searched the forum and Google as much as I could but can find anywhere that sells good road race wheels, rims or tyres..

Anyone have any ideas?

Try the recumbent forum.

Do they need the 547mm, 540mm, 520mm, or 507mm rims that are all labeled 24"? I will guess the 540mm size rim which is the same as most wheelchairs. Also called the 600A size. Also called 24" x 1 3/8". Or you could go with the 520m aka 24" x 1"

Both tyres can be found here:

The 520mm rim: https://www.everybicycletire.com/Shop...ohead-rim.aspx

520mm wheelset: https://www.everybicycletire.com/Shop...elset-520.aspx

If you build your own wheels, the Aerohead rim sold separately will be the "racier" one. Plus you can get the hubs of your choice.

Thanks very much for that it should be all the information i needed...

I got a set of 24" awhile back from here.

I got these for my kids bikes and they love them! a big step up from the standard MTB tire they had. I pump them hard and they roll well on the paved bike trails , but the kids can still have fun around the campground

I had a 24x1 1/4 (547mm) Varsity that would have been able to use a 26" (559) rim with a skinny street tire (like 26x1.00) with no problem.
I also had a junior Motobecane with some skinny 24" wheels. I forget the exact size but I still have them if you want them. They're steel but they're in decent shape.
