Recently purchased 18x8 wheels and yokohama yk520 tires 225/40/18 for 2006 tib se and have had trouble with vibrations even though tires have been balanced and rebalanced several times and there appears to be no problems with tires or wheels. Are there any recommendations on which all-season tires are best overall for this car? I am most concerned with a comfortable, smooth ride and durability for extensive highway driving and needs to be able to handle mild to moderate snow. Tires I have been considering to replace the yokos with are Bridgestone Pole Positions, Nitto NeoGen or Invo, Continental DWS, or Falken Ze912. I had a 2003 Tib in the past and had a number of problems with tires as well (rapid wear, uncomfortable ride) so am considering it may be just a common problem with this car. Thanks for the input.
