Dimax classic, any experience with this? They even have white walls.

Doesn't appear to be much in the way of tread. And white wall tyres are bloody awful on anything other than 1950s Americana. Even then they're questionable. What's the country of origin of these tyres? If they're Chinese then you're better off leaving old tyres in place with 2mm tread remaining. I have experience

Yes the profile is rubbish, the lamelles sit in the sidewall instead of the middle.
p.s. Some Tractions and DS did have michelin whitewalls.
