Tire height, front and back

Anyone running different tire heights front and back? I'm thinking of running a 195 x 60 on the back and a 195 x 50 on the front. Any comments?

195/50 are going to spin your speedometer cable faster, lower the front end, & have less give in them for shock absorbing quality. They look cool.

Tire diameter and gear ratios can be an issue. Also speedometer. Check out the following site. Maybe a 16" wheel with lower profile tire can give the same effect without changing the other qualities.

You can have your speedo calibrated to different tire sizes.

Thanks guys. I've decided to go with 195 x 60s all the way around. The 195s will just fit. I'm going with Yokohama AVS ES100s. Other choice was Pirelli P6000s 195 x 65s. The difference between 65s and 60s is about 100 rpm with my gear ratio. I will get my speedo calibrated , as soon as I find someplace to do it. It's already 10 mph out at 70 mph. I thought of going with 16 inch rims, but I couldn't find a high performance tire in a 195 x 16 and anything wider would rub.

Ron, North hollywood Speedometer or Palo Alto Speedometer can recalibrate your speedo. You can either take a rolling measurement per their instructions or just tell them it's for a 1966 VW with front wheel speedo drive and 195/60 tires. Palo Alto did my new instruments and I just told them the tire size.
