I agree with the mismatching R18 and R14 tires.

 

There is a wheel and tire forum?

 

Your translator is f*&/ed up.

 

The size you choose would depend on what you are looking for out of the tire and the specific tire you choose. You can run the stock S02's on those wheels just fine. You can also go to 225/50R16 and 245/45R16 in a tire like the Bridgestone RE750 to get better wet traction and longer life.
If I can help let me know.

 

Thanks! Thats all I needed

 

This is all assuming that the offsets are correct for the S2000, if not, all bets are off.
