polaris 993 sport

I just put on 17inch Nokian 55 zr hokka tires-on my 340 hp allroad Audi
Not sure how I like them-I am limited in size to 225 17 zr
Any opinions and how about the Michelin super a/s plus???
Nokian made a slight vibration slowing down from 100mph
I used to have perreli nerro's-but they stopped in my size
would it make a big difference to go from a 17 inch 55 to a 50. Need help asap as I can return the Nokian and get the other!!!

I am assuing that the Audi has the same size tires all around? 225's seem kinda small for a 340hp car.
I would recommend chekcing the Audi forums to see what other sizes fit your car (someone here might be able to answer this too) and then check out TireRack.com to see what's available for your car.
I would stick with the factory aspect ratio/width combination. If you go wider then you can drop to a 45 or maybe even 40 aspect ratio depending on what fits the rim/car.

Good Luck!

The 225/55-17 is the right size for the Allroad. Dunlop makes a nice all season (SP 5000) in a 225/55-17 that may be a good choice. I have run them on my A4 and been very happy with them (smooth & quiet) although I run Dunlop 3D Wintersports in the winter. Sorry I do not have experience with the Mich A/S
