The testing heroes at Sport Auto have answered a question we've all wanted to know the answer to! Just how good are all season tires in large wheel sizes on a performance vehicle?

To answer this, Sport Auto have tested six of the best all season tires, and included a NAMED summer and winter tire, the Bridgestone Potenza Sport UUHP summer tire, and the test winning Bridgestone Blizzak LM005 winter tire.

It's a good test.

Dry

What can we learn? Naturally the summer tire wins the dry tests, that's no surprise, but there's quite a big delta in dry braking and a huge difference in dry handling! The winter also places as you'd expect in dry handling, although it does beat the Goodyear Vector 4Seasons G3 in dry braking, which is always a weakness of that all season tire.

Wet

Wet braking is quite a surprise. The tests were done at 8c, and it's important to remember the Potenza Sport UUHP summer tire is one of the UUHP tires that does need a bit of temperature to work, but in this test the summer tire could only manage mid pack in wet braking and near the bottom during wet handling! The rear star is the winter tire, beating all the all season tires are relatively warm winter conditions, apart from the Vredestein Quatrac Pro, which is always outstanding in the wet.

Snow

Fortunately the winter tire was also the best in all the snow tests and the summer tire the worst.

As we've seen in other tests, the Michelin CrossClimate 2 is as close to a winter tire as any all season tire is.

Environment

Noise is an interesting test, with the summer tire by far the nosiest and the winter tire once again only being beat by the Vredestein. Summer tires are usually closer to all season tires in noise, this Potenza Sport is particularly noisy.

There was quite a spread in rolling resistance, with the AllSeasonContact proving to be the best of the group.

Interestingly all the all season tires were priced between the summer and winter tires.
