for those that came w/ 14's

[thebarber]

for those of us who's yaris came w/ 14's from the factory w/ 175-65-14 tires....it would seem as though the speedo is calibrated for 185-60-15 sizing...

i say this as i was driving w/ friends w/ oem-sized wheels and gps, and since we had radio's, i could ask what speed they were going.

it would seem that w/ 195-50-15 tires, my speedo was off by about 4km/h

that would lead me to believe that despite the fact that my car came with 175-65-14 tires, my speedo is calibrated for 185-60-15

just food for thought next time you're buying tires for your yaris
