Directional Marking

Directional tyres have been designed specifically to operate best when rotating in one direction. The tyre pattern is usually in the shape of an arrow with grooves running from the centre rib (middle) of the tyre to the outer shoulders. First engineered for racing in wet conditions, directional road tyres have excellent wet weather performance, due to their ability to displace large amounts of water from the road surface, while providing directional stability.

If you have a pair of directional tyres on your vehicle, they will usually have either an arrow or similar symbol indicating the direction they are designed to operate.

Speed Rating, Tyre Load & Pressure

Load Index: The load index is a numerical code associated with the maximum load a tyre can carry when inflated to operating pressure.

Pressure: Nearly all manufacturers print a maximum inflation pressure on the sidewall the tyre. It is important to note that this is generally not the recommended operating pressure for that tyre. If you are unsure of the correct inflation pressure for your tyres or the pressure description is missing, simply enquire at your local T-Mart or reference the tyre placard on your vehicle.

Speed Category Symbol: This indicates the maximum safe operating speed for the tyre when carrying a load within its load index rating.
