255/40R18 Continental ProContact GX – All Season EV Compatible M+S Touring

Category: All Season – Grand Touring

The Continental ProContact GX is an all season grand touring tire that comes as original equipment on some luxurious sedans and coupes. It provides excellent control in most weather conditions including light snow. ProContact GX tires also offer a smooth quiet ride. It also has a 105,000km tread life warranty for S and T rated sizes or 90,000km for H rated sizes.

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

What these tire specs mean

Load Index 99 is the tire’s standardized carrying capacity, supporting up to 775 kg per tire. Use it to confirm the tire meets or exceeds the load rating listed on your vehicle placard.
Speed Rating H indicates the tire’s maximum sustained speed capability under proper load and inflation. This is approximately 210 km/h under proper load and inflation.
All Season tires are made for mild year round driving, but they generally do not meet Quebec winter tire requirements unless they also carry 3PMS.
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.
