265/35R18 Michelin Pilot Sport AS 4 All Season
XL (Extra Load) — built to handle higher inflation pressures and heavier loads than a standard-load tire of the same size.
What these tire specs mean
Load index 97 means each tire can carry up to 730 kg. Check your door jamb placard — the tire needs to meet or beat the load rating your manufacturer specifies.
Speed rating Y is the maximum sustained speed this tire is designed to handle under proper conditions. That works out to 300 km/h under correct load and inflation — not a target, just the rated ceiling.
UTQG 540 AA A is a manufacturer-assigned grade for treadwear, traction, and temperature performance. Useful for comparing within the same brand — but it’s not a mileage guarantee, and ratings aren’t standardized across manufacturers.
All Season tires handle mild year-round conditions well, but they’re not winter tires. In Quebec, a standard all-season doesn’t satisfy the mandatory winter tire requirement unless it specifically carries the 3PMS symbol.
XL means Extra Load. These tires run at higher inflation pressures and handle more weight than a standard-load tire of the same size. If your vehicle’s factory spec calls for XL, that’s what you need — swapping to standard load can affect ride, handling, and safety.
EV Compatible means the tire is designed with electric vehicle demands in mind — higher load capacity for battery weight, reinforced sidewalls for EV torque, and compound choices that balance rolling resistance and road noise.
Vehicle type indicates the service category this tire is built for — passenger car, light truck, commercial, or other. Matching the right category matters for load capacity, handling, and safety.
Warranty coverage is backed by the manufacturer and applies under normal use — regular rotations, correct inflation, and proper alignment. Keep maintenance records if you ever need to make a claim.
Where this tire fits in
The 265/35R18 Michelin Pilot Sport AS 4 is a all season tire, built around a 265 mm section width for a 18-inch wheel.
In practical terms, this size gives you a 35-series sidewall of about 93 mm paired with a 18-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 97 and speed rating Y (~300 km/h), UTQG 540 AA A when provided by the manufacturer.
About the 265/35R18 tire size

265 — tread width in millimetres, measured across the contact patch
35 — sidewall height as a percentage of the tread width (roughly 93 mm of rubber between road and rim)
R18 — radial construction, for a 18-inch wheel
The 265/35R18 size is commonly found on full size SUVs and light trucks. Replacing a set? The full size marking is on your current tire’s sidewall — confirm width, profile, and rim diameter all match before you order.

Quebec winter tire mandate — all-season note
Quebec mandates winter tires from December 1 to March 15. The 265/35R18 Michelin Pilot Sport AS 4 is an all season tire — and without the 3PMS symbol, a standard all-season does not satisfy Quebec’s mandatory winter tire rule. If you drive in Quebec between December and March, a dedicated winter or all-weather tire is the right call. requirement unless they carry the 3PMS symbol. Consider a dedicated winter or all weather tire for Quebec driving.

Common questions — 265/35R18 Michelin Pilot Sport AS 4 All Season
What does the 265/35R18 tire size mean?
Break it down and 265/35R18 tells you three things: the tread is 265 mm wide, the sidewall stands at 35% of that — about 93 mm of rubber between road and rim — and it fits a 18-inch wheel. You’ll find this size most often on full size SUVs and light trucks.
Is the 265/35R18 Michelin Pilot Sport AS 4 an All Season tire?
Yes — the 265/35R18 Michelin Pilot Sport AS 4 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.
What does the 97Y rating mean on the 265/35R18 Michelin Pilot Sport AS 4?
The 97Y on the Michelin Pilot Sport AS 4 breaks into two numbers: load index 97, meaning each tire carries up to 730 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.
Is the 265/35R18 Michelin Pilot Sport AS 4 3PMS rated?
No — the Michelin Pilot Sport AS 4 doesn’t carry the 3PMS symbol. If Quebec winter compliance or severe snow traction is a priority, you’d want a tire that does.
Is the 265/35R18 Michelin Pilot Sport AS 4 studdable?
Studdable status is not confirmed for this tire. Reach out and we’ll check the manufacturer specs for you.
Does the 265/35R18 Michelin Pilot Sport AS 4 support run flat driving?
No — the Michelin Pilot Sport AS 4 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.
Is the 265/35R18 Michelin Pilot Sport AS 4 an XL (extra load) tire?
Yes — the Michelin Pilot Sport AS 4 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.
What does speed rating Y mean on the 265/35R18 Michelin Pilot Sport AS 4?
Speed rating Y on the Michelin Pilot Sport AS 4 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.
Can I order the 265/35R18 Michelin Pilot Sport AS 4 with delivery to Ontario or Quebec?
Yes — we ship the 265/35R18 Michelin Pilot Sport AS 4 across Ontario and Quebec. Free shipping • 1–3 business days (Ontario and Quebec).
