Vehicle Load Calculator
Check if your tyres are adequate for your vehicle's weight. Instant WOF compliance check with NZ vehicle presets.
Why Check Your Vehicle's Load Rating?
Every tyre has a load index number that tells you how much weight it can safely carry. If your tyres don't have sufficient load capacity for your vehicle, you could face:
- WOF failure – Inadequate load ratings will fail your Warrant of Fitness
- Safety risks – Overloaded tyres can fail catastrophically at speed
- Legal issues – Your insurance may be void if an accident occurs
- Premature wear – Tyres working beyond their capacity wear faster
This free calculator makes it easy to check if your tyres meet requirements. Just select your vehicle type and we'll show you if you're safe or need an upgrade.
