Something to think about also:
We bought Wide White Walls from Calli Tire in Sacramento.
They have a choice of tires that a customer can choose
from. My friend & I chose Cooper tires, essentially because
we liked the tread design.
Calli Tires does the same thing as Diamond Back- That is,
they vulcanize the whitewall to the existing tire, AFTER
removing the letters/numbers, etc., from the side they're
going to vulcanize. Now, having that done possibly negates
the tire MFG's warranty. I, and my friend Willie, had to sign
a notification that we are aware of this. Also, by law, those
letters/numbers are supposed to be visible to any authority,
and that we should make a note of those numbers/letters for
our own records.
Just a bit of info. Maybe Diamond back is different.
I don't anticipate any issues with the tires from Calli.
BTW, the tires are beautiful, and I'm a believer in using
new radial tires vs bias ply. Just my opinion here.
We both shied away from Coker because of all the bad press
re balancing/roundness, etc.
Re Continental Tires: I became a fan of those tires 20+ years
ago as they came as Standard Equipment on BMW M-3's,
with a very high speed rating. I put them on my 39 Coupe &
again on my 32 Tudor sedan. I can & do cruise the 32 at 80 mph
with confidence. Had they been available from Calli Tire, that
would have been my choice.
