snowshoes! (and gearing change)



Picked up a good set of four used Michelin X-ice winter tires on steelies today for a great price (150).

They're a little taller than the OEM tire (205 65 16 instead of 55) but they fit with no clearance issues... and they'll drop my cruising RPM a tiny bit. Win win!

>>> Stock tire diameter is 24.87795275590551 inches.
>>> New tire diameter is 26.49212598425197 inches.
>>> When the vehicle speedometer indicates 80 KM/H.
>>> The vehicle speed is actually 85.2 KM/H.

Gearing change of 6.5%

So RPM @ 80 km/h / 50 mph goes from ~2200 to 2057.

Now I just need to make up some smooth wheelcovers and we are good to go for the nasty season!
