Straight out the box I found the Michelin pilot sport 4 tires are superb. I have them Fitted to my front wheel drive A6 2.0tdi with 180bhp and 400nm
For a summer tyre (not being a track based tyre) it has Masses of dry grip, compared to my last set, Michelin pilot sport 3 they are everything I expected and more.
Then we get on to the important bit. Now I've watched hundreds of YouTube videos, read dozens of reviews trying to find out which is the best tyre for wet weather and how budgets compare to the premiums brands and so on, and I was a little sceptical on how good the pilot sport 4 really are, and from past experiences of driving many cars with various tyres choices, to compare to pilot sport 4's, When the rain starts to fall, The WET GRIP!! Absolutely astonishing. Apart from the road visually looking wet you wouldn't know you was driving on a wet Road. Even under hard braking and abit of second gear, foot down on a roundabout, and I plant all 400nm, It just bites the tarmac and goes. Turn in from the front tyres in the wet is excellent.
Wear rate still to early to say, but I would expect like all Michelins they will last a long time.
Road noise isn't noticeable for everyday driving. Though Audi cabins are particularly well insulated.
I can recommend these tyres enough.
