Tyre / rim problems :(

[pigman]

I was brought up with the rule that you never fully pump up brand new tyres. Pump them up to 2/3rds pressure, do a shortish (say 15 mile ride) and at that point they'll have flexed themselves into a secure position. Then you can pump them up to the hard pressure

Don't know if it actually makes any difference or the science behind it, just how I was advised many years ago

I had concerns about using modern lightweight folding bead 700c tyres on narrow Weinmann hookless rims but after exhaustive testing all was good. Not sure if there's any 27 inch folding bead tyres available so not much help really

Tyres with steel wire beads work better with hookless rims than kevlar-beaded folding tyres, IME.

I use 27" wire-beaded Panaracer Paselas on my old 27" rims. Good tyres.

Just ordered a pair from SJS as these sound (and also from the reviews, just the ticket

I use Michelin World Tour, Panaracer Pasala and Schwalbe Marathon wire beaded tyres on vintage Weinmann hookless rims and have had no problems at up to 80psi. Folding tyres are a no-no.

This is a. A lovely bike and b. Heartening news as the Pasala’s arrived and are currently at 70psi in the garage. Let’s see what the morning brings.

Was the original a marathong?
They are a popular tyre, we sell loads but I don't like them much.
thick and greasy.

The pasaela is in a different world of quality - I think this is probably the most likely solution
