Reply to "Adding 10"x15" to the rear"

So that 295/50-15 tire is 26.6" dia. with a stock ZF gearing 3200 rpm is 85 mph, change the 5th ratio to a 0.642 and you'd be going 93 mph, the 0.609 and you'd be at 99 mph!

The stock 0.846 4th and 0.705 5th aren't really far enough apart, it stands out when you look at a graphical representation of shift points and rpm drop, the tall 5th really does make for a great overdrive, if you have taller tires all the better.
