For those of us that change rims often or are always looking for what tire size to put on our cars.


First screenshot is the basic mode where u input the tire size and it tells u the difference in diameter.

The second shot expands so that u can see more detailed data such as Profile difference, overall diameter of tire and rim and even a section so that u can see how far off your speedometer is with the tire change :cheesy:


Here's the link. Let me know what u guys think

just remember.. the unloaded and loaded diameter of your tires are different, so the best formula is to actually measure from the ground to the centerline of the axle to get the radius...
Of course these are conceptual numbers.....going by rated tire size. There is no real way to tell actual difference considering load weight, tire inflation pressure, etc. But the idea is that all things being equal and in a perfect world, this thing is pretty damn close! And if anything just a good reference when changing tires to match something close.

NICE SOFTWARE....finally i know how fast i;m goin..
Sure beats the old way of having a friend with a stock car drive at 60mph in the front and see how high my speedometer goes. :)

its a neat program ,,,but the biggest prob,,and/or missed detail i see is,,,,,rim width,,like how a stock 14' rim is 14' by 5.5' and a hundred spoke is 13' by 7' ,,,that inch and a half makes a big difference in hight

why does the width matter? it could be 40" wide and its still turning the same number of revolutions..

Because the wider the rim, the more stretched out the tire becomes. there for the height becomes slightly less if the tire is stretched wide! or if the rim is skinnier like a 13x6 then the tire will be slightly taller.

Joe, did you create the program with VB?
I had started one a long time ago, but never finished it. Yours looks good!
