[s-cars] wheel offset and tire width

[Paul D.]

Forrest,

Here's a couple links I frequently use when trying to properly size 
tires/wheels.

Tire size calculator - give you a visual comparison of two tire sizes  
http://www.miata.net/garage/tirecalc.html
Offset calculator - http://www.1010tires.com/WheelOffsetCalculator.asp

I'm currently running 8.5x17 ET35 with 245x40x17.  I've very happy with 
the ride, handling, and look.  Like others have said, they rub at full 
turn and in reverse - they hit the mud flaps.  My S6 is lowered and I've 
never hit the fenders with the tires- front or rear.

HTH,

Paul D.
