Load index 89
One tire rated at load index 89 carries 580 kg, which is 1279 lb. Four of them carry 2320 kg (5115 lb) between them.
A load index is the capacity of one tire at the inflation pressure the standard specifies for that rating, on a correctly sized rim, on a sound and undamaged tire. It is not a capacity at any pressure you choose, and it is not a licence to load a vehicle past its own axle and gross weight ratings.

What load index 89 works out to
| Situation | Kilograms | Pounds |
|---|---|---|
| One tire | 580 | 1279 |
| One axle (two tires) | 1160 | 2557 |
| Set of four | 2320 | 5115 |
| One tire, P-metric or Euro-metric fitted to a light truck (divided by 1.1) | 527.3 | 1162 |
A P-metric or Euro-metric tire fitted to a light truck, van, SUV or trailer carries less than its load index states. Divide the rated load by 1.1. An LT tire of the same nominal size is not derated, which is why an LT size and a P size that look alike are not interchangeable at rated load.
A tire rated for dual (twinned) fitment prints two load indices, for example 121/118S. The first applies when one tire is mounted per hub, the second when two are. Look the second index up in this table rather than working out a percentage - the printed pair is the rating, and any percentage is a description of it.

Questions about load index 89
- What is load index 89?
- Load index 89 means one tire is rated to carry 580 kg, which is 1279 lb, at the inflation pressure the standard specifies for its load range.
- How much can four tires with load index 89 carry?
- 2320 kg (5115 lb) between them, if every tire is correctly inflated. That figure does not raise the vehicle's own gross weight rating, which is usually the lower limit and the one that governs.
- Is load index 89 enough for my vehicle?
- This site cannot answer that. The vehicle placard in the driver's door jamb states the load index the vehicle was built around, and a replacement has to meet or exceed it. That placard is the authority, not a table.

These are independent publishers, not independent measurements. Each one reproduces a table originally set by a standards body, so agreement between them shows a value was transcribed correctly, not that the underlying table is right. Where a figure is safety relevant, check it against the tire manufacturer's own data before relying on it.
