All,

Oh, and I forgot to add; there are two very useful

web sites you can check out:



http://www.tirerack.com/ has a very comprehensive listing

(and prices) of the tyres that they sell.



http://www.powerdog.com/tiresize.cgi has a tyre-size calculator.

This is very useful for calculating tyre diameters and widths,

especially if you dont want you car toooo looooowwww.

Here is what I calculated for some "common" tyre sizes:



Specification Sidewall Radius Diameter Circumference Revolutions Difference

---------------------------------------------------------------------------

225/50-15    4.4"   11.9"   23.9"    75.0"         845/mile    0.0%

285/50-15    5.6"   13.1"   26.2"    82.4"         769/mile    9.9%

305/50-15    6.0"   13.5"   27.0"    84.8"         747/mile   13.2%

345/35-16    4.8"   12.8"   25.5"    80.1"         791/mile    6.9%

345/35-17    4.8"   13.3"   26.5"    83.3"         761/mile   11.1%



Yeah, I know, the units are Imperial.  And I spell tyre correctly too!
