Hey all, just ran across a sweet tire size calculator on line.
I've been scrubbing through the worlds forums for the last 3 days now. (before I buy new rubbers) There are so many tire / wheel threads to read so I appologize if I am not putting this link in 'the' correct thread... I've seen a lot of different size calculators & links in here - but haven't seen this one posted. (& yeah it is from toyota) but totally applicable.
hope it may help someone.
cheers.
