    New tire recommendation in 18"

    I need new tires and was wondering if someone can recommend an All Season tire with decent performance but all about Cadillac smoothness.

    Also does anyone have any experience with Run Flat tires? I have heard some people complaining of Run Flat tires giving a harsh ride.

    I can get a great deal on the Cinturato P7 Run Flat tires. I am also thinking of the Ecsta 4X Kumho's or the Ventus S1 Hankook’s

    Runflat tires normally are rougher/harsher then NON Runflat tires.
    I have never used Kumho or Hancook tires so can't say one way ot the other.
    I am currently running Yokohama Advan S4 tires on my 2006.
    They are a lot quieter and ride better then the original Bridgestones.
    I have over 40,000 miles on them, and they are holding up real well.

    Remember that "smoothness" also depends on tire pressure, cold. The DTS (depending on option level) can be a decent "performance sedan", so increasing pressure (cold) above 30 psi gives better handling but increased ride noise and harshness.

    Tires are sort of a finality - most times, you put 'em on and you got 'em. Look at the Cooper CS4-V - great all season tires with long treadwear and a 45 day guarantee: "You don't like them, we take them back.". www.coopertire.com

    I just put Michelin Pilot Sport A/S 3's on my DTS and I have to say these are probably the best Michelin's I have ever driven on.
    They are considered a Ultra High Performance All Season tire.
    My last set of Michelin's were Primacy MXV4's and I got over 100'000kms on them.

    Re: New tire recommendation in 18"

    When I purchased my 2011 DTS Platinum in Jan. 2014 it had 18k on it
    being that it had sat so much the Continentals were flat spotted.

    I bought four Michelin Primacy MXM4 245/50R18 100H BSW as I had on my '08 DTS
    but could not swap them over as they were 17"

    Not only are they quiet but they feel fantastic on the curvy mountain roads around
    Sedona. I keep them @ 30psi
