Tires MICHELIN or Achilles

look into lightweight battery (I run a Braille 21lbs in my Nismo) and tires...the Michelin Pilot SuperSports are pretty lightweight.

i've replaced some RFTs on my Z4 with Michelin Pilot SuperSports, and LOVE them, but i doubt they're in your < $500 budget..

+1 Had these swapped onto the GTI from the GLI that I traded. On both, they were transformational. Exceptional dry grip, and almost as good in the rain. Amazingly low tire noise and pretty decent tread wear so far.

Michelin Pilot Super Sports. They are probably the best tire on the market. Fairly low noise as far as summer tires go. They grip well in the dry and the rain.

instead of so-so ContiProContacts, my baby is now sporting top-of-the-line treads - Michelin Primacy MXM's.

I have Michelin Pilot HX MXM4s on right now, and they're a nice tire.

No idea about prices and avaliability where you are but as far as winter tyres go I recommend Michelin and Nokian.

Michelin Pilot Sport all-seasons have been my chosen tire for the last year and a half, and I am really happy with them! Loads of grip, however because I opted for 225s, I hydroplane sometimes on standing water

I run Michelin XLT 'all-seaon mud and snow' tires, which are great in rain and ok in light snow, but frankly in real winter-y conditions are not good enough.
