Category: Truck/SUV All Season – Touring
The Continental CrossContact LX Sport is an all-season tire made for crossover utility autos. It is designed to provide a smooth quiet ride and offers good control in most weather conditions including light snow. The CrossContact LX Sport is intended to be driven on roads and highways.
XL (Extra Load) — built to handle higher inflation pressures and heavier loads than a standard-load tire of the same size.
The 275/45R21 Continental CrossContact LX Sport is a all season / truck/suv all season – touring tire, built around a 275 mm section width for a 21-inch wheel.
In practical terms, this size gives you a 45-series sidewall of about 124 mm paired with a 21-inch wheel diameter — confirm this against your current tire’s sidewall marking before ordering.
Worth noting on the spec side: this tire carries an XL extra load rating, load index 110 and speed rating Y (~300 km/h), UTQG 480 A A when provided by the manufacturer.

Quebec mandates winter tires from December 1 to March 15. The 275/45R21 Continental CrossContact LX Sport is an all season tire — and without the 3PMS symbol, a standard all-season does not satisfy Quebec’s mandatory winter tire rule.

Consider a dedicated winter or all weather tire for Quebec driving.

Yes — the 275/45R21 Continental CrossContact LX Sport is categorized as an All Season tire. Standard all-season tires handle mild year-round conditions but don’t meet Quebec’s mandatory winter tire requirement on their own. If you drive in Quebec between December and March, look at a dedicated winter or all-weather tire that carries the 3PMS symbol.
The 110Y on the Continental CrossContact LX Sport breaks into two numbers: load index 110, meaning each tire carries up to 1060 kg, rated to approximately 300 km/h; and speed rating Y, rated to 300 km/h under proper load and inflation. Your door jamb placard lists the minimum ratings your vehicle requires — match or exceed both.
No — the Continental CrossContact LX Sport doesn’t carry the 3PMS symbol. If Quebec winter compliance or severe snow traction is a priority, you’d want a tire that does.

No — the Continental CrossContact LX Sport is a standard tire, not a run flat. If your vehicle came equipped with run flats, your replacement set needs to be run flat-capable too.
Yes — the Continental CrossContact LX Sport is XL rated. It’s designed for higher inflation pressures and greater load capacity than a standard-load tire of the same size. If your current tires are XL, your replacement should be too.
Speed rating Y on the Continental CrossContact LX Sport corresponds to a maximum sustained speed of 300 km/h under proper load and inflation. In practice, this tells you the performance category the tire is built for — not a number to chase on public roads.
