205/40 R18 Y

The Accelera Phi-R in size 205/40 R18 86Y is a passenger car tyre designed to fit wheels with a 18-inch rim diameter. With a section width of 205mm and a sidewall height of approximately 82mm (40% of the section width), this size offers a balance of handling response, ride comfort, and grip suited to a wide range of vehicles.

This tyre carries a load index of 86, meaning each tyre is rated to support up to 530kg at the maximum permitted speed. The speed rating is Y, certifying the tyre for use at sustained speeds of up to 300km/h (186mph). Always ensure replacement tyres meet or exceed your vehicle manufacturer's recommended load and speed ratings.

According to the EU tyre label, the Phi-R 205/40 R18 86Y is rated for fuel efficiency at class G — the lowest fuel efficiency rating, often found on performance or off-road tyres, for wet grip at class E — basic wet grip; consider this when driving in heavy rain, with an external rolling noise level of 74 decibels. These standardised ratings make it easy to compare tyres on the factors that matter most for safety and running costs.

This summer tyre is optimised for warm-weather driving, delivering precise handling and short braking distances in dry and wet conditions when temperatures are above 7°C. The Extra Load (XL) construction strengthens the sidewalls to support heavier vehicles or increased payloads.
