Here is my blue one with 313's with Michelin PS2
Tot, quick question on the ride. Do you hear or feel any difference compared to yout 293s?

I did exactly wat you did. Swap mine 293s out and got the 313s with PS2.
When I drive at 60-80km/h range, I hear faint rotating blades coming into the cabin. Sounds like from the rear. The sound is more distinct if you take the foot off the pedal at 60-80km/h on a straight road.

Funny thing is that if I sit in the passenger side, the sound is very very faint..almost non-existent. I did wheel alignment and tire balancing and can't seem to get rid of the noise. Also checked all the wheel bearings from all 4. Did not seem to be the prob either.

Some folks told me that the bigger the rims (with big blades..not turbine type), you will hear more such noises.

U hear them?
