I am looking for a set of new tires for my 69 RR that look somewhat original and drive good,thinking about Cooper Cobra 225-70-15 about $100 each ?.The old Dunlop G70-15s look good but are are old and cracked and am scared to drive on them. Thanks for your help,recommendations,pics.

Depends on whether you want redlines or white letters (later production option), and whether by "drive good" you prefer radials or bias-ply.
I prefer radials for street driving over bias-plys myself, and have used Radial T/As & Firestone Indy 500s. If you want redlines, check out Coker Tire; IIRC, they have them in both radial and bias-ply.

Lots of good wheel and tire combinations out so as stated it's more the look that you want. For me I would check into and invest in the best shocks available at an affordable price and get a good alignment, that has made the most difference in ride quality than wheels and tires IMO.

I have had good luck with the Coopers, but last year was talked into Firestone Indy 500's by my tire distributor. I wasn't too crazy about the idea of having Firestones but he said if within a couple of weeks if I didn't like them he'd take them back. Well I still have them and I'm very impressed with the ride.
