Tire load index chart and speed ratings
Type the service description from the sidewall, like 94H or 114/111Q, to get the maximum load per tire in pounds and kilograms and the speed rating, or browse the full charts.
The load index is the number after the size (P215/65R15 95H). On an LT tire, two numbers such as 114/111 are the single and dual ratings. The load is the tire's maximum, at the pressure molded next to "Max. load" on the sidewall; at a lower pressure the tire carries less.

ZR in the size means a speed capability above 149 mph (240 km/h). A (Y) in brackets means above 186 mph (300 km/h); ask the tire maker for the top speed.
A tire's load index is a code for the most weight it can carry. Load index 75 is 387 kg (853 lb), 91 is 615 kg (1,356 lb) and 100 is 800 kg (1,764 lb), per tire. The letter after it is the speed rating: H is 130 mph (210 km/h), V 149 mph and W 168 mph. A replacement tire should carry at least the original tire's load.
How to use the Tire Load Index and Speed Rating Chart
Type the service description
The number and letter after the size, such as 94H, or 114/111Q on an LT tire.
Pick the vehicle type
For a P-metric tire on a truck, SUV or van, the load is divided by 1.10.
Read the load and speed
Load per tire, per axle and for four tires, and the speed rating, highlighted in the charts.
What the tire load index and speed rating chart works out
Load index 60 to 150
Maximum load per tire in kilograms and pounds.
Speed ratings L to Y
mph and km/h for each letter, plus (Y) and ZR.
LT dual ratings
Both numbers of an LT service description like 114/111: single and dual.
P-metric on trucks
The load divided by 1.10, as FMVSS 110 counts a passenger tire on a truck, SUV or van.
Axle and vehicle totals
Load for two and four tires.
- Load index
- A code for maximum load per tire, e.g. 94 = 670 kg (1,477 lb)
- Pounds
- From kilograms × 2.20462; charts round a few rows differently by 1 lb
- Speed symbol
- e.g. T = 118 mph (190 km/h), H = 130 mph (210 km/h), V = 149 mph (240 km/h)
- P-metric on a truck or MPV
- load rating ÷ 1.10 (FMVSS 110 S4.2.2.2)
- Not on every tire
- NHTSA notes load index and speed rating aren't required by law
