Wheel and Tire Sizes

[Mosesatm]

From what I've been able to figure out the diameter of the optional F70-14 tires was around 26 1/4" with a tread width of 6 3/4" and a cross section of 8 1/4". If those numbers are correct (or nearly so) the following list of tires and wheels should fit for overall diameter. Width and rubbing on the fenders is not taken into account.

14" Wheels
205-75 = 26.1"
215-70 = 25.8" (Fronts)
225-70 = 26.4" (Rears)
235-65 = 26.0"
255-60 = 26.0"
285-55 = 26.3"
305-50 = 26.0"
315.50 = 26.4

15" Wheels
185-75 = 25.9"
205-70 = 26.3"
215-65 = 26.0"
225-65 = 26.5"
235-60 = 26.1"
255-55 = 26.0"
285-50 = 26.2"
315-45 = 26.2"

16" Wheels
185-70 = 26.2"
195-65 = 26.0"
215-60 = 26.2"
235-55 = 26.2"
255-50 = 26.1"
260-50 = 26.2"
265-50 = 26.4"
285-45 = 26.1"
325-40 = 26.2"

17" Wheels
180-65 = 26.2"
195-60 = 26.2"
215-55 = 26.3"
235-50 = 26.2"
260-45 = 26.2"
295-40 = 26.3"
335-35 = 26.2"
