I know that the recommended size is 225/40-18. With the increase in sidewall height of the 225/45-18, will the setup look goofy? How large will be the increase in diameter of the 225/45-18 setup vs. the 225/40-18 setup? How much taller is the sidewall of the 225/45-18 than the 225/40-18?


thanks

found my own answer:

Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
215/45-17 3.8in 12.3in 24.6in 77.3in 819 0.0%
225/45-18 4.0in 13.0in 26.0in 81.6in 777 5.5%


Has anyone got this setup on their tC? How does it look?
