Not sure what a 99V tyre rating means? You’re not alone — it’s one of the most misunderstood tyre markings on the market. This guide breaks down exactly what 99V represents in load and speed rating, what vehicles typically use them, and how to choose the safest and most suitable tyres for your car or van.
If you trawl through our countless articles on tyre size calculations and tyre codes, then you will find several references to load and speed rating – and why these two pieces of information are so important…
Deciphering Load and Speed Rating
The number at the start of the tyre code equates to its load rating – that is, how much weight it can carry.
It’s important to understand that load rating is a cumulative figure. By this, we mean that the overall weight of the vehicle must be covered by all four tyres added up – meaning that one tyre doesn’t have to be able to carry the whole load.
The letter that sits after this load rating number equates to a speed rating at which the tyre can travel. This is a maximum and cannot be surpassed safely.
Why Does Load and Speed Rating Matter?
These pieces of information are critical when it comes to maintaining safe driving, ensuring good handling of the vehicle and minimising the risk of a tyre blowout.
Tyres with a higher load rating tend to be best suited to HGVs, vans and lorries – as well as agricultural machinery and tractors. Tyres with a higher speed rating are often performance cars, used in motorsport racing.
Where Does 99V Sit on the Scale?
99V boasts a load rating of just under 700kg – putting it high up on the load rating scale with its 99 rating.
The V means that the maximum speed the tyre can travel is 149mph – lower than many tyres.
This means that a 99V tyre will typically be best suited to an HGV that needs to be able to carry heavy loads, but that doesn’t need to be able to travel particularly fast.
