What's the performance difference between 15 inch, 16 inch and 17inch tires (all else equal)?
Assuming the same outside rolling diameter,
going from I.E. 15x6" wheels to 17x8" wheels:
- More stopping power
- More responsive steering
But:
- Less straight-line tracking
- Lower fuel economy
These can be overcome by:
1. Designing in more caster or
SAI for self-centering.
2. Reduce amount of power
steering boost.
3. Higher recommended cold tire
pressure.
