Quick answer
Load index 74 means each tyre can carry up to 375 kg (827 lb) at its rated pressure. Across one axle that's 750 kg, and across all four tyres 1500 kg.
Axle maths
| Configuration | Maximum load |
|---|---|
| One tyre | 375 kg (827 lb) |
| Per axle (2 tyres) | 750 kg |
| All four tyres | 1500 kg |
The usable figure is your vehicle's gross axle weight rating, which is always lower than the tyre total — the tyre rating just must never be the weaker link. Converting kg to lb or working out payload? The unit converters at 247QuickTools and the calculators at 247Calculators cover it.

Load index appears just before the speed symbol in the size code — e.g. 205/55 R16 74V. Never fit a lower index than your placard specifies; carrying loads also means watching pressures, so keep a digital tyre inflator handy, and if you tow or load up regularly a TPMS sensor kit makes top-ups easy.

FAQ
What does load index 74 mean?
Load index 74 certifies each tyre for a maximum of 375 kg (827 lb) at its rated pressure. Two tyres on an axle give 750 kg of tyre capacity.
Can I fit a lower load index than my placard shows?
No — never fit a lower index than specified. Equal or higher is the rule; XL (extra load) versions of the same size carry a higher index.
Does load index change with pressure?
The rated maximum applies at the tyre's specified pressure. Underinflation reduces real-world capacity and builds heat, which is why placard pressures matter when carrying loads.
