I have Hankook V12 on my 135I
225/40 R18's in front
255/35 R18's in back

What is the right PSI I should be running on these?

Thanks!!!!

I normally run 36F and 38R. I've also run 38 on all 4 and this works well too. You need to try a few different pressures to find the right feel between comfort, drivability and performance. If you run pressure to low your tyres will wear quicker too and your car will be less economical on fuel, although very minimal.

Do not forget what ever pressure you set your tires too... that you should also reset the TPMS via the button on the end of the turn signal stalk. This then "sets" your base system pressure. I did not realize this until just this week.

So... when ever anyone sets/checks thier tire pressures... you should reset the system.

I ran 36 on all four corners when I had that setup on my car.

I generally recommend about 36-38 as well. This seems to be the sweet spot for most cars and tires for good steering response and comfort.
