Data updated
Which should you buy?
Buy the Goodyear Vector 4Seasons Gen 3 if the tyre has to work in rain and snow, which is what an all season tyre is for; the Cooper Discoverer All Season only makes sense if noise, comfort and purchase price are the priorities and your winters stay mild.
Where the Discoverer All Season is stronger
- Shorter dry braking in four of five tests, by 5.8 percent in the 2024 Auto Bild Allrad test
- Quietest tyre in our 2025/26 test at 69.7dB, and the higher comfort score, 10 against 9.5
- Cheaper to buy, 67.90 against 87.00 in 2020, and it won both curved aquaplaning tests
Where the Vector 4Seasons Gen 3 is stronger
- Wet braking 31.4m against 34.5m in our 2025/26 test, and 50.7m against 59.6m at Auto Bild in 2021
- Won every snow measurement, including snow traction 21.56s against 28.03s in 2020
- Ahead in all five tests, an outright test winner in 2020 and highly recommended in 2025/26

Wins count every measurement the shared tests recorded for both tyres; a tick marks the tyre ahead on that line. Subjective driver scores count as wins but are never averaged, because each test uses its own scale.
Head to head in 5 tests, 2020 to 2025
Each row is one published test in which both tyres ran on the same car, in the same size, on the same day. The line is the whole field, winner on the left.

In each test the better of the two figures counts as 100% and the other as its share of it, so a 36 m stop against 34.2 m is 95%; each spoke averages the shared tests that recorded it. The scale stops at 85%: a point further in sits on the hub's edge, hollow. 7 measurements recorded in only one shared test are left off; every measurement is in the table further down.

Braking distances and lap times are better when lower; speeds, wear and grip figures when higher. A test's figures are its own: sizes, cars, surfaces and temperatures differ from one to the next, which is why the averages here are only ever of tests the two tyres shared. "Scored" rows are subjective driver ratings: each test uses its own scale, so only the wins are counted.
Scores beyond the shared tests

All 1 Discoverer All Season reviewsI bought this tyre from Camskill at very low promotional price. They did over 50 k miles and I am really impressed from the accuracy of steering and handling. These tyres like wet roads and feels like they grip more. I tried premium tyres and these were better and quieter and I wish I can find them again on offer.

Owners rate the Goodyear Vector 4Seasons Gen 3 highly overall (average 79.9%), with most praising its dependable all-round grip, particularly in the wet, where over half of reviewers comment positively. Dry grip, snow traction and cold-weather performance are also frequently highlighted, and around a third of owners report strong tread life. The main recurring downsides are a noticeably weaker dry braking performance and slightly vague steering feel, raised by around one in five and around one in six owners respectively, while road noise feedback is mixed but leans positive.
- Confident wet grip in heavy rain and greasy conditions
- Strong dry grip for everyday driving
- Long tread life and slow wear rates
- Impressive snow traction for an all-season tyre
- Longer dry braking distances / less bite under heavy braking
- Vague or light steering feel and less direct response
- Higher rolling resistance / noticeable fuel economy drop for some drivers

Reading the results
Written from the test results and owner reviews above. It is analysis, not a measurement: where it and the tables disagree, the tables are right.
Five shared tests going back to 2020, and the Goodyear Vector 4Seasons Gen 3 finished ahead of the Cooper Discoverer All Season in all five, including as outright winner of our own 2020 all season test where the Cooper came 9th of 11.
The Cooper is not without its moments, and one of them is a surprise: it stopped shorter in the dry in four of the five tests, by 5.8 percent in Auto Bild Allrad's 2024 minivan and SUV test, 43.8m against 46.5m. It was also the quieter tyre twice, the cheaper tyre twice, and it won both curved aquaplaning comparisons.
Everything else runs the other way, and it runs that way hard. In our own 2025/26 test the Goodyear braked 3.1m shorter in the wet, lapped the wet handling course six seconds quicker and was scored 10 against 7.5 subjectively there, then beat the Cooper on every snow measurement as well. For a tyre bought to cope with a British winter, that is the whole argument.
Conclusion
The Goodyear Vector 4Seasons Gen 3 is the tyre to buy, and the wet and snow numbers are why. In our 2025/26 all season test it stopped in 31.4m against the Cooper's 34.5m, a 9 percent gap, lapped the wet handling course in 85.1s against 91.1s and took a subjective wet score of 10 against 7.5. Auto Bild's 2021 market overview found the same thing on a bigger scale, 50.7m against 59.6m in wet braking, nearly nine metres. On snow it won braking, traction and handling in every test that measured them, including 21.56s against 28.03s in our 2020 traction run. It also rolls easier, by 18.1 percent in that same test, and it was highly recommended in 2025/26 and the outright winner in 2020.
The Cooper Discoverer All Season keeps three things worth naming. It braked shorter in the dry in four of the five tests, it was the quietest tyre on test in our 2025/26 comparison at 69.7dB, and it is the cheaper tyre, 67.90 against 87.00 in 2020 and 560 against 600 in 2024. Our testers also gave it the higher comfort score, 10 against 9.5, and it won both curved aquaplaning tests.
Our own note on the Cooper is blunt: below average dry, wet and snow performance with high rolling resistance, against a Goodyear described as excellent in dry handling, best in wet handling and good on snow. Buy the Cooper only if noise, comfort and purchase price are what you are optimising for and your winters are mild. If the tyre has to work in rain and snow, the Goodyear is worth the difference several times over.

Where this data comes from
Finishing positions and measurements are transcribed from each published test. A test only counts here when both tyres ran in it, so every figure was recorded on the same car, size and day as the one it is compared to.
About the TR Score
The Tyre Reviews Score rates each tyre out of 10 from every independent test result and vetted owner review we hold, so two tyres can be compared even before a test has run them together.
Who does the testing
Every test published as a Tyre Reviews test is run by Jonathan Benson, who has been testing tyres independently since 2007.
