What changes if you switch

- Wheels: both fit a 17-inch wheel; check the tire's approved rim width range.
- Sidewall: a shorter sidewall usually sharpens steering but rides firmer and is more prone to pothole damage.
- Effective gearing: slightly shorter, so marginally quicker acceleration and higher rpm at speed.
- Match the original load index and speed rating or higher, and check for rubbing at full steering lock and full suspension compression.
