Tire Diameter Affect on HP TQ?
I gotta start of by saying I DID search and found almost nothing...
Has anyone tested the performance attributes of various tire diameters? Gears, cams etc. are designed with stock wheels/tire diameter in mind. In a 240 that is roughly 24 - 25 inches Stock S13 195/60-15 have a diameter of 24.2" Stock S14 205/55-16 have a diameter of 24.9" (Per: http://www.federaltire.com/download/specFD1.pdf ) My theory: If over sized wheels/tires hurt 0-30, under sized wheels/tires should help 0-30. This would make all gears "lower" so the engine is revving higher at the same gear. Making a car better at time attack... or zipping around town. I am thinking 195/45R15 or 215/35R16 both @ 21.9" Any Zilvians tried this? |
