What is the current factory size on your IS? And to help us better help you in selecting the correct tire, tell us some of the things you are looking for? IE: long tread life, good wet weather & snow traction, how much you want to spend etc. The more detailed you are the better. B) The Pirelli's are a pretty popular choice, but there are others. I got 4 new 225/45/17 Pirellis and so far I am very happy with my decision. Thanks for your reply.

I decided to get new tires for my 2001 IS and need some help with the size and the brand. I live in the northeast area so I want to get All-Season tires. Pirelli PZero Nero M&S got very good reviews on tirerack.com. Do you think pirelli is a good choice or what will be the best choice? I am also thinking of putting 225/45/17 front and 245/45/17 back.Has anyone tried this before? Do you think it might cause problems if I use different size tires? Any suggestion on this? Thanks.

How can it be fixed???

there is a weird noise coming from the left front (from the ventilation) when it is between 3000 and 4000 rpms. It sounds like air sucking or water boiling. it doesn't happen when the AC is on. I took it to the service but they couldn't figure out what it is. Any ideas or have anyone had the same problem?
