Brooks---Your new wheels and tire package is very close but taller than
the original tire and rim size. Here's the formula for determining such
things:
Original tire and rim~185x.78+15"=
185 (metric, converted to standard) =
185x.0394=7.29" (tire width)
7.29x.78 (% of the width)=5.685
5.685x2=11.37 + rim diam. = 26.37
The height of the stock tire and rim = 26.37 inches
Your non-stock tire and rim would figure this way:
215x.65x2+16=
8.47x.65x2+16= 27 inches
Your new setup would make an otherwise stock speedometer read 2.4%
slower at all speeds.

Ashford :
Thanks for the compliment
I am running the Michelin MX4 215/65 R16 It ends up with a inflated
diameter of 26.5" I believe this to be 1/2" bigger than stock?--- can
someone please confirm this?----when I was reworking the instruments I
decided to do a little shoot from the hip style calibration by removing the
needle and reinstalling it back about 3-4 MPH I must have got real lucky
because when I pass by this local Robocop that displays your speed, I am
dead nuts accurate.---When I first installed the new wheel/tire assm. I was
shocked and thought I went too big but after I installed the bumpers, I was
very pleased, especially the the ride that an almost perfect alloy wheel
runout provides.---- Because of the zero wheel offset the interference
encountered is the use of clip on weights on the top "A" arms so I use tape
weights.----As far as performance goes all I can say is it's a heck of alot
better ride and handling than my 76 six with the stock steel wheels and the
PO installed uniroyal 195/75 R15's
Cheers,
Brooks
