Hello. I was thinking of getting newer replica 17" Campi wheels for my 74 Pantera, but cost of those wheels and tires are a bit steep for me right now. As all you may know..15 inch high speed and proper size tires are scarce. My car has 8 inch wide front, and 10 wide rear campi wheels. After a long search, I found some Nittos that work great! I have 225/50/15 Nittos Extreme Performance front, and 275/50/15 Nittos Drag radials rear. These are V rated tires(149 mph). The rears are nearly 26" tall, and the tread measures 6/32 deep. They can last up to 15k miles, and grip like no tomorrow! My daughter Charity and I went on a twisty road, and these tires really took the turns like the car was on rails.
Since I only cover about 1000 miles a year, I am not concerned about the "softness" and low life mileage of the rear tires, the grip is worth it!
I will try to post some pics soon.

These are not unstable tires by any means as the above data and discription shows. They have a max. pressure of 44psi. I set mine at 38 rear and 34 front on the Nitto Extremes. What can I say, it took corners as fast as I dare go...and I could tell I wasn't even close to slipping.
