A good fit if you
- Warm, dry, and wet roads where grip matters more than cold-weather resilience.
- 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.

275/40R21 Hankook K137A Summer
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 107 means each tire can carry up to 975 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 A 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 275/40R21 Hankook K137A is a summer tire, built around a 275 mm section width for a 21-inch wheel.
In practical terms, this size gives you a 40-series sidewall of about 110 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 107 and speed rating Y (~300 km/h), UTQG 180 A A when provided by the manufacturer.
About the 275/40R21 tire size
The 275/40R21 breaks down into three numbers:
- 275 — tread width in millimetres, measured across the contact patch
- 40 — sidewall height as a percentage of the tread width (roughly 110 mm of rubber between road and rim)
- R21 — radial construction, for a 21-inch wheel
The 275/40R21 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.
What stands out — Hankook K137A 275/40R21
- XL (Extra Load) rated — handles higher inflation pressures and heavier loads than a standard-load equivalent.
- UTQG 180 A A — manufacturer-assigned treadwear, traction, and temperature grades. Useful for comparing within the same brand, but not a mileage guarantee.
- Service description 107Y: load index 107 means each tire carries up to 975 kg, speed rating Y is rated to 300 km/h.
- 275/40R21 mounts on a 21-inch wheel.

Common questions — 275/40R21 Hankook K137A Summer
What does the 275/40R21 tire size mean?
Break it down and 275/40R21 tells you three things: the tread is 275 mm wide, the sidewall stands at 40% of that — about 110 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 275/40R21 Hankook K137A a Summer tire?
Yes — the 275/40R21 Hankook K137A is categorized as a Summer tire.
What does the 107Y rating mean on the 275/40R21 Hankook K137A?
The 107Y on the Hankook K137A breaks into two numbers: load index 107, meaning each tire carries up to 975 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 275/40R21 Hankook K137A 3PMS rated?
No — the Hankook K137A 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 275/40R21 Hankook K137A studdable?
Studdable status is not confirmed for this tire. Reach out and we’ll check the manufacturer specs for you.
Does the 275/40R21 Hankook K137A support run flat driving?
No — the Hankook K137A 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 275/40R21 Hankook K137A an XL (extra load) tire?
Yes — the Hankook K137A 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 275/40R21 Hankook K137A?
Speed rating Y on the Hankook K137A 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 275/40R21 Hankook K137A with delivery to Ontario or Quebec?
Yes — we ship the 275/40R21 Hankook K137A across Ontario and Quebec. Free shipping • 1–3 business days (Ontario and Quebec).
