Tire Sizes to fit 20's
Rochester,
There are a number of wheels that will fit the AWD. AWDriver is correct. In my investigation there are a number of companies that make for the AWD. There are a number of threads on that topic.
On the sizing I just returned from a Big O Store who is owned by a friend and we came up with a sizing chart. It may be helpful to others as well.
Tire Comparisons
................................STOCK
width...........................225.........255.........245..........255
Aspect Ratio...................60..........50...........45............45
Rim Size.........................18..........20...........20............20
Sidewall Height..............5.31.........5.02........4.34........4.52
Section Width................8.86.......10.04........9.65.......10.04
Overall Diameter...........28.64......30.04......28.68.......29.04
Circumference..............39.94........94.37......90.10.......91.22
Revs per Mile..............726.51.......692.41....725.24......716.25
Speedometer
at 65............................65..........68.20......65.11........65.93
The overall diameter is the one we need to watch because of clearance with the arm and the nut. In this scenario it looks like the 255/50/20 is going to be to large. The 255/45/20 should still give enough clearance. The 245/45/20 looks to be the closest to current. But make sure you do your checking with the experts as well. There are other sizes that will work but I found this information to be helpful for my understanding.
