Thank you for all of your inputs to previous posts.
I have checked with Michelin, they discontinued the Symmetry White Wall tire and the only White Wall tire they produce is the Uniroyal Tiger Paw (Uniroyal is part of Michelin).
The TigerPaw AWP II is available in a 5/8"WW width as a P205/75R15 and a P215/70R15. This brings up the next question - what are the pros and cons of going with the original 205/75 vs the 215/70 in view of converting to 6" knock-off rims?
I'm on a tight budget for my 67 convertible with factory rally wheels-bought Hancook (don't laugh) Optimo 724, 205/75-15, i put blackwall on outside, cost was $90/each, very pleased with dry and wet road grip, balanced well, reasonably comfortable.
Tires look good!
Any problems fitting them to the knock-off rims?
Well, I wasn't there when my tire guy mounted them (I must trust him a lot) but no issues as far as I know. After getting used to looking at the BFGs on my '72 (15x8 rallies) the 205/75s look tiny. Hopefully one fine day when the '64 is driveable I'll have a huge traction problem!
