A good fit if you

- Drivers who already swap to a dedicated winter set when temperatures drop below 7°C.
- Factory fitments or vehicles that specifically require XL-rated tires.
Think twice if you need
- Winter driving — summer tires harden in the cold and won’t satisfy Quebec’s winter tire mandate.
- Anyone who wants one set of tires to cover all four seasons in Ontario or Quebec.

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 108 means each tire can carry up to 1000 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 180 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.
- Summer tires are built for maximum warm-weather grip — dry and wet roads where compound stickiness and tread design matter most. They harden in near-freezing temperatures and are not suitable for Ontario or Quebec winter driving.
- 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.
- 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.
Where this tire fits in
The 325/30R21 Michelin Pilot Sport Cup 2 is a summer tire, built around a 325 mm section width for a 21-inch wheel.
In practical terms, this size gives you a 30-series sidewall of about 98 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 108 and speed rating (Y) (~300 km/h), UTQG 180 AA A when provided by the manufacturer.
About the 325/30R21 tire size
The 325/30R21 breaks down into three numbers:
- 325 — tread width in millimetres, measured across the contact patch
- 30 — sidewall height as a percentage of the tread width (roughly 98 mm of rubber between road and rim)
- R21 — radial construction, for a 21-inch wheel
The 325/30R21 size is commonly found on performance vehicles and heavy duty 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.

Common questions — 325/30R21 Michelin Pilot Sport Cup 2 Summer
What does the 325/30R21 tire size mean?
Break it down and 325/30R21 tells you three things: the tread is 325 mm wide, the sidewall stands at 30% of that — about 98 mm of rubber between road and rim — and it fits a 21-inch wheel. You’ll find this size most often on performance vehicles and heavy duty trucks.
Is the 325/30R21 Michelin Pilot Sport Cup 2 a Summer tire?
Yes — the 325/30R21 Michelin Pilot Sport Cup 2 is categorized as a Summer tire.
What does the 108(Y) rating mean on the 325/30R21 Michelin Pilot Sport Cup 2?
The 108(Y) on the Michelin Pilot Sport Cup 2 breaks into two numbers: load index 108, meaning each tire carries up to 1000 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 325/30R21 Michelin Pilot Sport Cup 2 3PMS rated?
No — the Michelin Pilot Sport Cup 2 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 325/30R21 Michelin Pilot Sport Cup 2 studdable?
Studdable status is not confirmed for this tire. Reach out and we’ll check the manufacturer specs for you.
Does the 325/30R21 Michelin Pilot Sport Cup 2 support run flat driving?
No — the Michelin Pilot Sport Cup 2 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 325/30R21 Michelin Pilot Sport Cup 2 an XL (extra load) tire?
Yes — the Michelin Pilot Sport Cup 2 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 325/30R21 Michelin Pilot Sport Cup 2?
Speed rating (Y) on the Michelin Pilot Sport Cup 2 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 325/30R21 Michelin Pilot Sport Cup 2 with delivery to Ontario or Quebec?
Yes — we ship the 325/30R21 Michelin Pilot Sport Cup 2 across Ontario and Quebec. Free shipping • 1–3 business days (Ontario and Quebec).
