What is the Authentic Bias Ply for 63 Avanti R2?

I have a 1963 R2, Looking to go "authentic" due the repeated discussion of how '60s cars do not have

radially tuned suspensions. Also, that "tall" look looks very retro, and you cannot get that in radials.

Here are the questions:

1. What was the original size for Avanti R2, Coker says 670-15, but I have it elsewhere as 950-15.

2. This is the current Coker offerings, sans pricing, as publishing their pricing would be tacky...

Which is the "Most Authentic?"

670-15 B.F.GOODRICH 1 INCH WHITEWALL TIRE

670-15 B.F.GOODRICH 2 1/2 INCH WHITEWALL TIRE

670-15 B.F.GOODRICH 3 5/8 INCH WHITEWALL TIRE

670-15 B.F.GOODRICH BLACKWALL TIRE

670-15 COKER CLASSIC 2 3/4 INCH WHITEWALL TIRE

670-15 FIRESTONE 1 INCH WHITEWALL TIRE

670-15 FIRESTONE 2 1/4 INCH WHITEWALL TIRE

670-15 FIRESTONE 2 11/16 INCH WHITEWALL TIRE

670-15 FIRESTONE 3 1/4 INCH WHITEWALL TIRE

670-15 FIRESTONE BLACKWALL TIRE

thanks!

I have no idea on the bias ply, though I would never use them on a daily

driven car. One thing that people tend to justify using outdated technology

is that "it worked before, so why switch?" The problem with that is that all

the OTHER cars on the road can outstop and out handle you. So if the car

in front of you can stop in 10 feet shorter distance - what happens when

they come to a complete stop suddenly?

Radial tuned is mostly in the shocks, not a lot changed in the 70's when the

industry changed over to radial tires. If you look at the 1995 Impala SS

front suspension, compared to the 1965 Impala, its almost identical. The

95 Impala uses 17 x 9 wheels, and P255/50ZR-17 tires. The only difference

between the two front suspensions is the shock technology. Spring rates

might have been changed a little also.

Not knocking keeping a car stock, just pointing out that there isnt really a

"Radial Tuned" suspension .. thats kinda buzz word for salesmen.

670-15's 2 1/4" white wall.standard equipment. Though you could get black walls.

Some early cars were shown with 2 1/4" white walls, but my original 25,000 mile `63 R-1 has the unused spare tire and wheel in the trunk, and it is a 670-15 Firestone with the 1" white stripe.
