285/30R21 Continental ContiSportContact 5P – EV Compatible Performance Summer

Category: Summer – Supreme Performance

The Continental ContiSportContact 5P is a summer max performance tire. It is designed specifically for prestigious high performance vehicles. It offers a smooth, quiet ride and though it provides excellent handling in dry and wet conditions, the ContiSportContact 5P is not designed to drive in icy or snowy environments.

XL (Extra Load) rating supports higher inflation pressure and carrying capacity than standard load tires.

What these tire specs mean

  • Load Index 100 is the tire’s standardized carrying capacity, supporting up to 800 kg per tire. Use it to confirm the tire meets or exceeds the load rating listed on your vehicle placard.
  • Speed Rating Y indicates the tire’s maximum sustained speed capability under proper load and inflation. This is approximately 300 km/h under proper load and inflation.
  • Summer tires are built for warm weather grip and should not be used as winter tires in Ontario or Quebec cold weather conditions.
  • XL means Extra Load. These tires are designed to carry higher loads at higher inflation pressures than a standard load tire in the same size, which matters for heavier vehicles, loaded vehicles, or factory fitments that require XL.
  • Vehicle Type helps identify whether the tire is intended for passenger, light truck, commercial, or similar service categories.
