What these tire specs mean
- Load index 125 means each tire can carry up to 1650 kg. Check your door jamb placard — the tire needs to meet or beat the load rating your manufacturer specifies.
- Speed rating S is the maximum sustained speed this tire is designed to handle under proper conditions. That works out to 180 km/h under correct load and inflation — not a target, just the rated ceiling.
- 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.
- 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.

Consider a dedicated winter or all weather tire for Quebec driving.

Common questions — 275/70R18 Firestone Transforce HT3 All Season
What does the 275/70R18 tire size mean?
Break it down and 275/70R18 tells you three things: the tread is 275 mm wide, the sidewall stands at 70% of that — about 193 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 275/70R18 Firestone Transforce HT3 an All Season tire?
Yes — the 275/70R18 Firestone Transforce HT3 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 125S rating mean on the 275/70R18 Firestone Transforce HT3?
The 125S on the Firestone Transforce HT3 breaks into two numbers: load index 125, meaning each tire carries up to 1650 kg, rated to approximately 180 km/h; and speed rating S, rated to 180 km/h under proper load and inflation. Your door jamb placard lists the minimum ratings your vehicle requires — match or exceed both.
Is the 275/70R18 Firestone Transforce HT3 3PMS rated?
No — the Firestone Transforce HT3 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 275/70R18 Firestone Transforce HT3 studdable?
Studdable status is not confirmed for this tire. Reach out and we’ll check the manufacturer specs for you.
Does the 275/70R18 Firestone Transforce HT3 support run flat driving?
No — the Firestone Transforce HT3 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 275/70R18 Firestone Transforce HT3 an XL (extra load) tire?
No — the Firestone Transforce HT3 is a standard load tire, not XL. Check your vehicle door placard or current tires to confirm what’s required before ordering.
What does speed rating S mean on the 275/70R18 Firestone Transforce HT3?
Speed rating S on the Firestone Transforce HT3 corresponds to a maximum sustained speed of 180 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 275/70R18 Firestone Transforce HT3 with delivery to Ontario or Quebec?
Yes — we ship the 275/70R18 Firestone Transforce HT3 across Ontario and Quebec. Free shipping • 1–3 business days (Ontario and Quebec).
Why buy the 275/70R18 Firestone Transforce HT3 from XYZTires if another tire looks cheaper?
