Very new to this and the points calculation for stock vs. new tire width has me confused. The formula reads: The points to be assessed by a tire width change are computed by subtracting the increase in width in mm divided by 10 to get the number of cm increase. The points are calculated by the cm difference times a multiplier. The multiplier is 2.0, 2.5, or 3.0 depending on the upgraded tire's aspect ratio. Width multiplier new tire aspect ratio. 2.0 80-70 2.5 65-55 3.0 50 - 30 Points = ( [new width mm – stock width for each axle] / 10 ) * (width multiplier) Stock tires on my 05 Cooper S were 195/55-16 and my new tires are 205/50-16 all around. Does the formula count both tires for "each axle" or what? Can someone show me the correct points number? Thanks!!!
