    17" vs 18" Dillemma again

    Sorry to ask this same question again.

    I'm in the market to buy aftermarket rims. I liked the look of the ROH RT rims I seen on a TA in GM High Tech Performance. It had 18" x 10 in the back and 18" x 9 in the front with Nitto 556 Extreme IIs (I think).

    I love the look but problem for me is my A4 TA is a daily driver. I live in Texas so weather is usually not too bad but I do travel to the Midwest from time to time.

    Questions:

    #1 How significantly is the ride decreased with 18" versus 17" rims? Is it worth getting 18" and sacrificing some ride for a daily driven vehicle? I remember a thread that mentioned the performance differences were negligible between the two.

    #2 Do you think it's a bad idea to get 10s in the back and 9s in the front for a daily driven vehicle and prevent tire rotation?

    #3 Tires again. Some tire guys recommended BFGR KDWSs but a lot of guys in this forum are very partial to the Firestone Firehawks. Another tire guy said I could use Nittos as a daily driven vehicle tire. What do you guys think.

    Thanx again for the help.

    I saw a report that compaired 15s, 16s, 17s, and 18s. There was benifit in going from 15s to 16s, 16s to 17s, but not from 17s to 18s.

    I would recomend not getting a steel rim wheel. I had 16x8s with 245-50x16s on them and every one got bent from pot holes and bridges. The lower the series number on the tire the more likely you will get rim damage.

    FYI one of the reasons I like the Firestone SZ-50 is they have a rim gaurd beed on them that helps prevent rim damage.

      I agree with Jeff- the firestones are the way to go for SUMMER driving- My buddy with an 02 Firehawk has them and it sticks like crazy. However, if you are planning on running these all year round and in the snow, like I do, I would recommend the G-force KDWS tires, as they're still Z-rated but not ice skates in the snow like the firehawks are.
