Category: All Season – Ultra High Performance
The Continental ExtremeContact DWS06 Plus is a premium, ultra-high performance all-season tire for passenger cars, crossovers and SUVs. Ideal for true, year-round traction, this tire comes complete with SportPlus Technology, which provides responsive handling, better grip on wet roads, and extended tread life. The ExtremeContact DWS 06 Plus is an upgrade from the original and performs better in dry & wet braking and handling as well as snow & ice performance. 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 103 means each tire can carry up to 875 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 560 AA 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.
EV Compatible means the tire is designed with electric vehicle demands in mind — higher load capacity for battery weight, reinforced sidewalls for EV torque, and compound choices that balance rolling resistance and road noise.
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.
Where this tire fits in
The 255/45R18 Continental ExtremeContact DWS06 PLUS is a all season / all season – ultra high performance tire, built around a 255 mm section width for a 18-inch wheel.
In practical terms, this size gives you a 45-series sidewall of about 115 mm paired with a 18-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 103 and speed rating Y (~300 km/h), UTQG 560 AA A when provided by the manufacturer.
About the 255/45R18 tire size
The 255/45R18 breaks down into three numbers:
255 — tread width in millimetres, measured across the contact patch
45 — sidewall height as a percentage of the tread width (roughly 115 mm of rubber between road and rim)
R18 — radial construction, for a 18-inch wheel
The 255/45R18 size is commonly found on mid size SUVs, crossovers, and sport sedans. 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 — Continental ExtremeContact DWS06 PLUS 255/45R18
XL (Extra Load) rated — handles higher inflation pressures and heavier loads than a standard-load equivalent.
Marked as EV compatible — designed with EV load, torque, and road noise characteristics in mind.
UTQG 560 AA A — manufacturer-assigned treadwear, traction, and temperature grades. Useful for comparing within the same brand, but not a mileage guarantee.
Service description 103Y: load index 103 means each tire carries up to 875 kg, speed rating Y is rated to 300 km/h.
Quebec winter tire mandate — all-season note
Quebec mandates winter tires from December 1 to March 15. The 255/45R18 Continental ExtremeContact DWS06 PLUS is an all season tire — and without the 3PMS symbol, a standard all-season does not satisfy Quebec’s mandatory winter tire rule. If you drive in Quebec between December and March, a dedicated winter or all-weather tire is the right call. requirement unless they carry the 3PMS symbol. Consider a dedicated winter or all weather tire for Quebec driving.

Common questions — 255/45R18 Continental ExtremeContact DWS06 PLUS All Season
What does the 255/45R18 tire size mean?
Break it down and 255/45R18 tells you three things: the tread is 255 mm wide, the sidewall stands at 45% of that — about 115 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 255/45R18 Continental ExtremeContact DWS06 PLUS an All Season tire?
Yes — the 255/45R18 Continental ExtremeContact DWS06 PLUS 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 103Y rating mean on the 255/45R18 Continental ExtremeContact DWS06 PLUS?
The 103Y on the Continental ExtremeContact DWS06 PLUS breaks into two numbers: load index 103, meaning each tire carries up to 875 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 255/45R18 Continental ExtremeContact DWS06 PLUS 3PMS rated?
No — the Continental ExtremeContact DWS06 PLUS 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 255/45R18 Continental ExtremeContact DWS06 PLUS studdable?
Studdable status is not confirmed for this tire. Reach out and we’ll check the manufacturer specs for you.
Does the 255/45R18 Continental ExtremeContact DWS06 PLUS support run flat driving?
No — the Continental ExtremeContact DWS06 PLUS 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 255/45R18 Continental ExtremeContact DWS06 PLUS an XL (extra load) tire?
Yes — the Continental ExtremeContact DWS06 PLUS 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 255/45R18 Continental ExtremeContact DWS06 PLUS?
Speed rating Y on the Continental ExtremeContact DWS06 PLUS 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 255/45R18 Continental ExtremeContact DWS06 PLUS with delivery to Ontario or Quebec?
Yes — we ship the 255/45R18 Continental ExtremeContact DWS06 PLUS across Ontario and Quebec. Free shipping • 1–3 business days (Ontario and Quebec).
Why buy the 255/45R18 Continental ExtremeContact DWS06 PLUS from XYZTires if another tire looks cheaper?
A lower sticker price is worth comparing, but the full picture includes shipping cost, delivery timeline, whether it’s actually in stock, and whether the tire category is right for how you drive. We focus on making those details clear upfront — so you can compare real delivered value, not just the first number you see.
