I run the 305/35-18 at the track and they are definitely shorter than stock..probably 3" shorter. Next time I will get 305/45-18. With a 6spd car it probably is of no consequence, but with an auto the transmission shifts at weird rpm due to the wheel speed being different than indicated. Most times it is fine.
