I have a MTB with Wolber AT 18, 559 (26") rims. It's an old rim and has served me for many years.
The old Kenda tyre that was on it fit perfectly and was easy to get on and off when I had the occasional puncture on the trail. But it was old and had to be replaced.
This old well fitting tyre was a Kenda with 26 x 2.35 to fit HB-575 rim written on it.
The actual outside diameter of the AT-18 rim with the tyre off is 571mm. I measured it.
So I got a couple of cheap replacement tyres, Raleigh Eiger MTB tyres from tredz spec'd as 26 x 2.10 (56 x 559).
They had a very thick side wall with very in-fexible bead compared with the old Kenda tyres which had a much thinner tyre wall and very flexible bead.
I measured the inner diameter of the returned Raleigh tyre with a measure tape and it was approx 552 mm.
These newly purchased (Raleigh) tyres did not fit.
When I say they did not fit I did eventually manage to get them on, but only after an hour long struggle. Getting them off was even worse.
I have fitted many many bike tyres in my time and never come across this tight fitting problem before now. These tyres had to go back to the supplier becasue in the event of a puncture on the trail I would never be able to get them off.
The old Kenda tyres I could roll on and off with my hands more or less - ideal for fixing punctures on the trail. Easy fitting too.
Clearly there are tight tyres and lose tyres.
Can anyone recommend how I can find a 26 x 2.35 to fit a HB-575 rim at a good price that will roll on and off the AT-18 rim?
