Re: 1969 Wheel and Tire Combo's ... 15" Dia. Wheels Only
My 69 came with and still has on the front Weld Racing Draglite 15”x7” Mag wheels with B.F. Goodrich P205/65 R15 92T M&S tires. On the rear Weld Racing Draglite 15”x9” Mag wheels with Hankook P265/50 R15 99S M&S tires. The rears are a snug fit but no rubbing or tire damage, the upper lips on the rear quarter panels have been relieved a bit. When I wear them out, I'm planning on changing the tires (and possibly the rims but not sure yet) so the outside tire diameter will be closer to or even slightly larger than the stock diameter it was originally born with.
The Hankook P265/50 R15 rear tires have an outside diameter (when new) of 25.4" which comes out to 818 revolutions per a mile and 3,325 rpm's at 65 mph. The original as born with tires had an outside diameter of 26.6" which comes out to 781 revolutions per mile and 3,063 rpm's at 65 mph. Hankook has a 295/50 R15 tire that has an outside diameter of 26.6" BUT it is too wide to fit without major surgery. With the as born with 3.73 gears in the rear, lowering the revolutions per mile or rpm's at highway cruise is definitely something I find favor with.
If/when I change the rear tires, I would also change the front tires (once they were worn enough or if the new rear tires make the look with the existing fronts unacceptable). For the rear tires I'm thinking BF Goodrich Radial T/A 255/60 R15 with an outside diameter of 27.1” which is only a half inch larger than the as born with diameter with 769 revolutions per mile and 3,006 rpm's at 65 mph and with the same tread width as the Hankook's I have now.
For the front's I've narrowed it down to a couple of possibilities. The first would be the BF Goodrich Radial T/A P215/65 R15 which is just over an inch smaller diameter than the rear tires would be, but a wider tread at 7.50" and I've read others that have reported that they ran them just fine up front with no rubbing issues. The second front tire option would be the BF Goodrich Radial T/A P215/70 R15 which is only two tenths of an inch smaller in diameter than the new rear tires would be, but a one inch narrower tread width of 6.50" than the first new front tire option, so I'm leaning towards the first option right now for the extra contact area they would provide.
As far as rims/wheels go, if/when I change them, I'd go with a set of aftermarket reproduction Rally Wheels but chrome plated rather than painted so that the trim rings would not be necessary and only center caps would need be used with them for a very similar appearance to the original Rally wheel look but with a bit more shine!
