Those are great! Similar to Dunlop vintage motorcycle tires I found for one of mine. Can you post details on them (size, brand, model #)?
These are Firestone 4.50 x 21. Made in Canada. They are old, but are not showing their age. Not NOS, but really nice and not very used. I have another pair that are considerably more "used"!!!
I have been "inventorying ".
I have a narrowed TT rear axle (ex snowmobile). My 2 cylinder Medicine Hat foundry 1/2 T engine
Those would be wicked rear tires on a hill climber!
At least on a dirt track!!!
Man, I'd love to have a set for my WWI military vehicle Model T. Motorcycle tires are the look, but too narrow and too low profile.
I'm still looking for something.
Les - sent you a PM.
