Fitting a decent set of track-focused or semi-slick tyres to your track car is one of the best mods you can do. Why? because they're designed for the job! Semi-slick tyres typically feature a larger rubber surface area which gives you a bigger contact patch and more mechanical grip, the rubber compounds, while often softer than a standard road tyres will not overheat as quickly. Stiffer sidewalls make for more predictable handling and less 'roll over' and wear on the tyre's outside edge during hard cornering.
A good set of track tyres will transform the handling of your car and it will be a whole lot more enjoyable on track!
