Dual Tyre Mismatch Calculator
Check rolling-circumference mismatch on dual axles
Formula: mismatch_percent = abs(circumference_a − circumference_b) ÷ max(circumference_a, circumference_b) × 100
When two tyres on a dual axle differ in rolling circumference by more than 0.5%, the larger one carries disproportionate load — leading to uneven wear, overheating, and premature failure. This calculator quantifies the mismatch so you can re-pair tyres before they cost you a casing.

Warnings & checks
- ⚠Mismatch exceeds the 0.5% safe limit for dual tyres — uneven wear and overheating risk.
Recommended next actions
- →Do not pair mismatched dual tyres
