Load index 121
How much weight is load index 121?
Load index 121 means a maximum load of 1450 kg (3197 lb) per tire.
| Max load (kg) | 1450 kg |
|---|---|
| Max load (lb) | 3197 lb |
| Sum of two nominal ratings | 2900 kg |
What this value can decide
The sum 2900 kg is only 1450 × 2, for two nominal single-tire ratings. It does not increase the vehicle’s permitted axle weight or payload. Compare the manufacturer’s maximum laden axle weight, full tire marking and required pressure; dual tires need their own rating.
