245/40R18 Firestone Firehawk AS – All Season Performance
Category: All Season – High Performance
The Firestone Firehawk AS is Firestone's best high performance all-season tire. This improved tire delivers more control in wet and snowy conditions, and extended performance even as the tire wears. With added channels, full-depth features, and 20% more biting edges the Firehawk AS has a lower risk of hydroplaning and increased traction and control in winter weather conditions. It also has a 80,000km tread life warranty for all sizes.
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 V is the maximum sustained speed this tire is designed to handle under proper conditions. That works out to 240 km/h under correct load and inflation — not a target, just the rated ceiling.
- UTQG 480-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.
- 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.
- 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.

Common questions — 245/40R18 Firestone Firehawk AS – All Season Performance All Season
What does the 245/40R18 tire size mean?
Break it down and 245/40R18 tells you three things: the tread is 245 mm wide, the sidewall stands at 40% of that — about 98 mm of rubber between road and rim — and it fits a 18-inch wheel. You’ll find this size most often on mid size SUVs, crossovers, and sport sedans.
Is the 245/40R18 Firestone Firehawk AS – All Season Performance an All Season tire?
Yes — the 245/40R18 Firestone Firehawk AS – All Season Performance 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 97V rating mean on the 245/40R18 Firestone Firehawk AS – All Season Performance?
The 97V on the Firestone Firehawk AS – All Season Performance breaks into two numbers: load index 97, meaning each tire carries up to 730 kg, rated to approximately 240 km/h; and speed rating V, rated to 240 km/h under proper load and inflation. Your door jamb placard lists the minimum ratings your vehicle requires — match or exceed both.
Is the 245/40R18 Firestone Firehawk AS – All Season Performance 3PMS rated?
No — the Firestone Firehawk AS – All Season Performance doesn’t carry the 3PMS symbol. If Quebec winter compliance or severe snow traction is a priority, you’d want a tire that does.

Does the 245/40R18 Firestone Firehawk AS – All Season Performance support run flat driving?
No — the Firestone Firehawk AS – All Season Performance 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 245/40R18 Firestone Firehawk AS – All Season Performance an XL (extra load) tire?
Yes — the Firestone Firehawk AS – All Season Performance 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 V mean on the 245/40R18 Firestone Firehawk AS – All Season Performance?
Speed rating V on the Firestone Firehawk AS – All Season Performance corresponds to a maximum sustained speed of 240 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.
