Tire Load Index Chart & Meaning
A tire’s load index is a numerical service code that corresponds to a defined maximum load capacity under specified conditions. Follow the vehicle tire placard, the vehicle manufacturer, and the tire manufacturer — not this chart alone.
Signature example
225/65R17 102 H
102 Load index
850 kg kg per tire
1,874 lb lb per tire
Maximum rated load per tire under specified conditions — not vehicle payload capacity.

Load index lookup
Enter a load index from 71–130. Values come from TireReference’s production rating resolver.
102 Load index
850 kg kg per tire
1,874 lb lb per tire
Maximum load per tire under specified rating conditions.
What does load index 102 mean?
102 Load index
850 kg / 1,874 lb Maximum rated load per tire under specified conditions
It does not mean
- the vehicle can carry 4 × 850 kg of payload
- the axle can carry that amount
- a tire with index 102 fits every vehicle
- tire pressure and operating conditions are irrelevant

Load index is rated per tire
Mapped kilograms and pounds are maximum load per tire under specified conditions (including the inflation used for that rating).
850 kg per tire
4 tires
3,400 kg four-tire sum
vehicle payload rating
Vehicle payload, axle ratings, GVWR, tire pressure requirements and placard specifications are separate constraints. Do not calculate payload from tire capacity alone.
Load index vs load range
Load range
Examples: C, D, E
Construction/load category. Older “ply rating” language is an equivalent label, not a count of actual plies. Load range alone does not give exact carrying capacity.
- B 4-ply rated
- C 6-ply rated
- D 8-ply rated
- E 10-ply rated
- F 12-ply rated
- G 14-ply rated
Load index ≠ load range. A tire’s load index and load range describe different things. SL (standard load) and XL (extra load / reinforced) describe passenger-tire load versions — they are not substitutes for reading the numeric load index.
“10-ply rating” is a rating designation, not necessarily a literal count of ten physical carcass plies in a modern tire.
Can you use a higher load index?
A higher index means a greater mapped maximum load, but selecting a replacement also requires matching size, pressure requirements, speed rating, wheel compatibility, and the vehicle specification. This page does not certify suitability.
Same tire size, different load index
Matching tire size alone does not guarantee an identical service description. Indexed TireReference products:
Same dimensions ≠ same rated load capacity.
FAQ
What does load index 94 mean?
In the TireReference mapping, load index 94 corresponds to 670 kg (1477 lb) maximum load per tire under specified conditions. Follow the vehicle placard.
What does load index 102 mean?
In the TireReference mapping, load index 102 corresponds to 850 kg (1874 lb) maximum load per tire under specified conditions.
Can I use a higher load index?
A higher index indicates greater rated load capacity, but replacement still has to satisfy size, inflation, speed rating, wheel compatibility, and the vehicle manufacturer’s requirements. It is not an automatic approval.
Can I use a lower load index?
Do not step below the load capacity required by the vehicle tire placard and the tire manufacturer. A lower index is a lower mapped maximum load per tire.
Is load index the same as load range?
No. Load index is a numeric service code mapped to a maximum load. Load range (and older ply-rating language) describes a construction/load category such as C, D, or E. Load range alone does not give exact carrying capacity.
Is tire load index per tire?
Yes. The mapped kilogram and pound values are maximum load per tire under specified conditions. Multiplying by four is not a vehicle payload rating and does not replace axle ratings or the placard.
