Quick Specs

Size: 255/40R20
Brand / Model: Hankook H452B
Season: All Season
Vehicle Type: Passenger
Load / Speed: 101H (Load index 101 supports up to 825 kg per tire; speed rating H rated up to 210 km/h)
Certifications: Run flat, XL (Extra Load)
Delivery (Ontario & Quebec): Free shipping • 1–3 business days (Ontario and Quebec)

Run flat design allows you to still drive a short distance despite having a puncture. Must be used with a compatible vehicle and TPMS.

What these tire specs mean

Load Index 101 is the tire’s standardized carrying capacity, supporting up to 825 kg per tire. Use it to confirm the tire meets or exceeds the load rating listed on your vehicle placard.
Speed Rating H indicates the tire’s maximum sustained speed capability under proper load and inflation. This is approximately 210 km/h under proper load and inflation.
UTQG 460 A A is the manufacturer treadwear, traction, and temperature grading system. It is useful for comparing tires from the same brand, but it should not be treated as an exact mileage promise.
All Season tires are made for mild year round driving, but they generally do not meet Quebec winter tire requirements unless they also carry 3PMS.
XL means Extra Load. These tires are designed to carry higher loads at higher inflation pressures than a standard load tire in the same size, which matters for heavier vehicles, loaded vehicles, or factory fitments that require XL.
Run flat tires can temporarily support the vehicle after pressure loss, allowing you to keep control and drive a limited distance to service. Note that they require a compatible vehicle setup and a working TPMS system.
Vehicle Type helps identify whether the tire is intended for passenger, light truck, commercial, or similar service categories.
Warranty coverage is manufacturer backed and depends on normal use, proper maintenance, rotation, inflation, and alignment conditions.

How this tire is positioned

255/40R20 Hankook H452B is positioned as a all season tire built around a 255 mm section width and 20-inch wheel fitment.

In practical terms, this size combines a 40-series sidewall of about 102 mm with a 20-inch wheel diameter, which is useful when matching an existing tire size and wheel setup.

Feature wise, this tire indicates run flat construction, an XL extra load rating, load index 101 and speed rating H (~210 km/h), UTQG 460 A A when provided by the manufacturer.

About the 255/40R20 tire size
