Redmoon Converters Compare dois tamanhos de pneu quaisquer (ex.: 225/45R17 vs 245/40R18) quanto ao diâmetro total, circunferência, % de erro de velocímetro e mudança de folga.
| Métrica | Pneu A | Pneu B | Δ |
|---|
Formato métrico P W/AR-D: flanco (mm) = largura da seção × aspecto / 100. Diâmetro total (mm) = 2 × flanco + aro × 25,4. Circunferência = π × diâmetro. Voltas/milha = 1.609.344 / circunferência.
Erro do velocímetro na velocidade indicada = (diâmetro.B − diâmetro.A) / diâmetro.A × velocidade indicada. Positivo = velocidade real maior do que a mostrada ao usar o pneu B.
