235/55R19 Nitto NT-421Q – All Season
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 105 means each tire can carry up to 925 kg. Check your door jamb placard — the tire needs to meet or beat the load rating your manufacturer specifies.
- Speed rating W is the maximum sustained speed this tire is designed to handle under proper conditions. That works out to 270 km/h under correct load and inflation — not a target, just the rated ceiling.
- UTQG 560 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.
- Warranty coverage is backed by the manufacturer and applies under normal use — regular rotations, correct inflation, and proper alignment. Keep maintenance records if you ever need to make a claim.

Common questions — 235/55R19 Nitto NT-421Q – All Season
What does the 235/55R19 tire size mean?
Break it down and 235/55R19 tells you three things: the tread is 235 mm wide, the sidewall stands at 55% of that — about 129 mm of rubber between road and rim — and it fits a 19-inch wheel. You’ll find this size most often on sport sedans, coupes, and luxury vehicles.
Is the 235/55R19 Nitto NT-421Q – an All Season tire?
Yes — the 235/55R19 Nitto NT-421Q – 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 105W rating mean on the 235/55R19 Nitto NT-421Q -?
The 105W on the Nitto NT-421Q – breaks into two numbers: load index 105, meaning each tire carries up to 925 kg, rated to approximately 270 km/h; and speed rating W, rated to 270 km/h under proper load and inflation. Your door jamb placard lists the minimum ratings your vehicle requires — match or exceed both.
Is the 235/55R19 Nitto NT-421Q – 3PMS rated?
No — the Nitto NT-421Q – doesn’t carry the 3PMS symbol. If Quebec winter compliance or severe snow traction is a priority, you’d want a tire that does.

Studdable status is not confirmed for this tire. Reach out and we’ll check the manufacturer specs for you.
Does the 235/55R19 Nitto NT-421Q – support run flat driving?
No — the Nitto NT-421Q – 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 235/55R19 Nitto NT-421Q – an XL (extra load) tire?
Yes — the Nitto NT-421Q – 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 W mean on the 235/55R19 Nitto NT-421Q -?
Speed rating W on the Nitto NT-421Q – corresponds to a maximum sustained speed of 270 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.

Yes — we ship the 235/55R19 Nitto NT-421Q – across Ontario and Quebec. Free shipping • 1–3 business days (Ontario and Quebec).
Why buy the 235/55R19 Nitto NT-421Q – from XYZTires if another tire looks cheaper?
