Do You Still Need Winter Tires on a 2026 INEOS Grenadier Station Wagon?
October 28 2026,
The 2026 INEOS Grenadier Station Wagon looks ready for any kind of weather, and its hardware backs that up. Permanent four-wheel drive, a two-speed transfer case and 264 mm (10.4 in) of ground clearance give it solid footing on snowy roads and unplowed trails. So it’s fair to ask if a vehicle this capable still needs a dedicated set of winter tires.
The answer surprises a lot of new owners. The Grenadier Station Wagon leaves the factory on all-terrain tires that already carry the official winter tire symbol. Here’s what that means, how Quebec’s winter tire rule treats those tires, and when a separate winter set still makes sense.
What Tires Come on the 2026 Grenadier Station Wagon?
The standard tire is the Bridgestone Dueler A/T 001, an all-terrain tire developed specifically for the Grenadier. Bridgestone gave it an upgraded rubber compound and an all-terrain tread that carries the Three-Peak Mountain Snowflake (3PMSF) symbol on the sidewall.
The Grenadier rides on hard-wearing 17-inch steel wheels as standard. Owners can also choose 18-inch steel wheels, 17-inch alloys or 18-inch alloys, and the Black Edition wears gloss-black 18-inch alloys. Every wheel uses the same six-stud pattern.
For drivers who head into extreme terrain, INEOS also offers BFGoodrich All-Terrain T/A KO2 tires. They use a more aggressive tread, and their deep, reinforced sidewalls add puncture resistance. Tire pressure monitoring is standard on every Grenadier, and you can check each tire’s pressure on the central touchscreen.
What the Three-Peak Mountain Snowflake Symbol Means
The 3PMSF symbol is a small pictogram on the tire’s sidewall. It shows a mountain with three peaks and a snowflake inside. A tire can only wear this mark after passing a standardized snow traction test.
The symbol matters because it is the one Canadian drivers and regulators look for. A tire marked only “M+S” (mud and snow) does not carry the same meaning. When you shop for any tire for winter use, the mountain and snowflake is the first thing to check.
What Quebec’s Winter Tire Rule Says
Quebec requires winter tires by law. According to the Société de l’assurance automobile du Québec (SAAQ), from December 1 to March 15 inclusive, passenger vehicles registered in Quebec must be equipped with four winter tires. Since December 15, 2014, only tires that carry the official pictogram, along with studded tires, count as winter tires under the Highway Safety Code.
Because the Grenadier’s standard Bridgestone Dueler A/T 001 tires carry the 3PMSF symbol, they qualify under that rule. If you ever replace them, check the sidewalls of all four new tires for the pictogram before December 1.
The SAAQ also points out that winter conditions often arrive before the legal date. Installing your winter-ready tires early and keeping them on a few weeks past March 15 is a smart habit.
Do Four-Wheel Drive and Locking Differentials Replace Winter Tires?
The Grenadier carries a serious traction setup. Here’s what works together every time the roads turn white:
- Permanent four-wheel drive, with no switch to remember
- A two-speed transfer case with a centre differential that locks in both high and low range
- A 2.5:1 low-range ratio for slow, controlled driving in deep snow
- Front and rear differential locks, standard on the Trialmaster Edition and available on other versions, which disengage automatically at higher speeds to protect the drivetrain
Downhill Assist brakes individual wheels to keep the Grenadier steady on steep descents. Uphill Assist holds the vehicle in place after you release the handbrake on a slope.
All of these systems help the Grenadier find grip and keep moving. Braking and turning on snow and ice still come down to the four patches of rubber touching the road. That is why tire choice stays important, even on a vehicle with this much traction hardware.
When a Dedicated Winter Set Still Makes Sense
The standard all-terrain tires keep the Grenadier compliant with Quebec’s winter tire rule. Some drivers still choose a dedicated winter set, and there are good reasons to do it.
A dedicated winter tire is built around one job: grip in cold weather. If most of your winter driving happens on icy pavement, or if you cover long highway distances in harsh conditions, a winter tire with the pictogram is worth a look.
A second set of tires also lets you save your all-terrains for spring, summer and fall trail use. Mounting the winter set on its own wheels makes the seasonal swap quicker each year. Since every Grenadier wheel uses the same six-stud pattern, our team can help you match a winter setup to either 17-inch or 18-inch wheels.
