Notes

  • **119T means two separate things.** 119 is the load index: this tire carries **2,998 lb** on its own, at the pressure printed on the sidewall. T is the speed rating: the tire is built to hold together at **118 mph**. The two numbers are unrelated — a high load index says nothing about speed, and vice versa.
  • **The load figure is per tire, not per vehicle.** Four 119-rated tires carry 11,992 lb between them, and that has to cover the car, the fuel, the passengers and whatever is in the boot. Compare it against the gross vehicle weight rating on the door jamb, not against the kerb weight in the brochure.
  • **Never fit a lower index than the door label.** The placard inside the driver's door gives the minimum load index the manufacturer signed off on. Going below it is the one substitution in tire fitment that has no upside — it saves a few dollars and removes margin from the only four patches of rubber holding the car down.
  • **A speed rating is a ceiling, not a recommendation.** T at 118 mph assumes correct pressure, correct load and a tire in good condition. Under-inflation is what actually destroys tires at speed, and it does it well below the rated number.
  • Both markings sit at the end of the size, after the diameter: a tire marked 225/45R17 119T is a 225-wide, 45-series, 17-inch tire rated 2,998 lb and 118 mph.

119T is two answers, not one

119 is the load index: this tire carries 2,998 lb on its own. T is the speed rating: the tire is built to hold together at 118 mph.

The two are unrelated. A high load index says nothing about speed, and a fast tire is not automatically a strong one.

The load figure is per tire

Four 119-rated tires carry 11,992 lb between them — and that has to cover the car, the fuel, the passengers and everything in the boot.

Compare it against the gross vehicle weight rating on the door jamb, not the kerb weight in the brochure. The two numbers differ by several hundred pounds on most cars, and the brochure is the one that flatters.

Never fit a lower index than the door label

The placard inside the driver's door gives the minimum load index the manufacturer signed off on.

Going below it is the one substitution in tire fitment with no upside: it saves a few dollars and takes margin out of the only four patches of rubber holding the car on the road.

A speed rating is a ceiling, not a recommendation

T = 118 mph (190 km/h) assumes correct pressure, correct load and a tire in good condition.

Under-inflation is what actually destroys tires at speed, and it does it well below the rated number.

Where to find it on the sidewall

Both markings sit at the end of the size, after the diameter — a tire marked 225/45R17 119T is a 225-wide, 45-series, 17-inch tire rated 2,998 lb and 118 mph.
