maybe u misunderstood me...i mean break down the technical terms and stuff so i can understand it so i can figure it out...cuz i have no idea what this means:
ConvConst = RevsperMile x ToneRingTeeth / 8000
(The '87-current 8.8" rear end has a 108-tooth tone ring.)
What's that? You say you don't know how many revolutions your tires make per mile?????
RevsperMile = 20168.11439/TireHeight
The height of metric tires (for instance P265/75R15 - 265mm wide, aspect ratio 75, rim height 15") is calculated by:
Height = 2 x Width x (AspRatio/100) x .0394 plus RimHeight
Since metric tire width (LT265/75R15) and flotation tire height (31x10.50R15) are nominal and not the actual dimensions, using these formulas will result in an approximate value for RevsperMile. The actual numbers for each particular size, model, & make of tire are published and available at Tire Rack.
or dont i have to worry about it?
