Plus Size Calculator
Going to larger wheels? The Plus Size Calculator finds equivalent tire sizes for +1 and +2 rim upsizing that maintain approximately the same overall diameter.
What is Plus Sizing?
Plus sizing means fitting a larger diameter wheel while using a shorter sidewall tire to maintain the same overall diameter. Common upgrades are +1 (one inch larger rim) and +2 (two inch larger rim).
Benefits
- Improved handling and cornering response
- Better brake cooling
- Enhanced appearance
Cautions
- Shorter sidewalls reduce ride comfort and pothole resistance
- Always verify wheel well clearance
- Keep overall diameter within ±3% of original
