a tyre question

Speedo error is not of concern with these tyre size changes. In fact, there is speedo error right out of the box with the Vitz/Yaris with OEM 14, 15, and 16 inch diameter wheels/tyres.

just a second , forgive me for my car ignorance but how can 15' inch wheels have different diameters like 23.4 and 23.7 ? (doesn't 15 = diameter )

and how about filling the tyre with nitrogen instead of air which is better ?

Some tires can be the same size but have a different total diameter. It depends on the tread depth. Some tires come with a 9/32 tread depth while some others might have 10/32 or 11/32. Some may be even more than that.

also depends on the width wheel mounted and actual section width which isn't always the advertised # on the sidewall. :)

germans or whoever built it should have had a conference call with some sort of Mechanical Engineer (09TRD!!!!!)
