Default Re: A Focus-friendly tire diameter chart

EDIT: Thanks to Z63R for pointing out that REV per MILE INFO IS INCORRECT. I am currently updating this table with the correct information. Sorry to anyone who I've inconvenienced. My original source was faulty.


In light of just having to adjust my speedo with my Xcal2 to read correctly with my new tire size, I thought I'd add a little value to this chart by adding the revolutions per mile for each tire size. I also noticed that most of the tire diameters were off by a tenth or so, and I corrected where appropriate.

Also, '05s do NOT have 300mm SVT front brake rotors. THey are a unique size inbetween the SVT & <'05 NON-SVT front rotors.
