As per title, to fit 355s. Cheers 😀

You don't need rimstrips – just yellow tape and a valve.

Even if your using non ust tyres?

Yes, just without the valve!
(edit) that's if you're running them non tubeless..

I thought you needed the yellow tape under the rimstrip. But you can just run the yellow tape, bang in a valve and that's it? Sounds too simple!!!

AFAIK: if running tubeless you can either run:

yellow tape and ust tyres
yellow tape and normal tyres (but may not seal well & may burp)
any tape and rim strip and non-ust tyres

If you are running tubes you will need some rim tape (any kind should be fine).

BTW not sure if they are cheapest but JustRidingALong is the first stop for all things tubeless.

Cheers guys
