Semi slick tyres promise race-level grip and speed, but they’re not designed for the realities of UK roads. This article explains what semi slicks are, why they’re banned for everyday driving, and how to achieve high performance legally and safely.
In order to understand exactly what semi slick tyres are, you first need to know a little bit about motorsport racing and the different types of tyres that are fixed to race cars.
It is only then that we can look at semi slick tyres and whether they are legal for regular driving. So, let’s get stuck in.
What Are Slick Tyres?
Slick tyres are commonly used in the worlds of F1 and other races, offering superior speed and grip on dry surfaces. These tyres feature no tread pattern and are instead completely smooth, creating that trademark squealing noise and offering unrivalled traction on a dry race track.
The emphasis here is on slick tyres being used on dry surfaces only.
Owing to the lack of tread pattern, these tyres are not safe for wet surfaces – and are replaced in wet conditions by specifically designed wet tyres. Nonetheless, in the right conditions, they can elevate the speed and handling of a professional vehicle tenfold.
What Are Semi Slick Tyres?
With that in mind then, what are semi slick tyres?
In the simplest terms, these are tyres which boast many of the attributes of slick tyres, but with the bare minimum in tread depth and pattern.
Because semi slick tyres feature some grooves in the surface finish of the tyre, they do not offer the same quality in dry road handling – but they are a little more versatile in that they can be driven on wet roads too. They reduce the risk of aquaplaning on a wet surface, making them safer than slick tyres if you’re unsure on the weather conditions for race day.
But what about the use of semi slick tyres on regular roads and in everyday driving?
Can you Drive With Semi Slick Tyres on Your Car?
No – it is not legal to drive on slick or semi slick tyres on regular roads in the UK.
These tyres are designed with race tracks and performance in mind, and are maintained in line with high speed, short bursts of driving. They are not safe or stable on a normal road, or when fixed to the regular car.
If a driver is caught with slick or semi slick tyres fitted to their car, they will receive fines and/or penalties.
