    The rears are wider than the fronts... Dealer said they dont get rotated.

    I thought I read somewhere that you can put the same size on all the way around without hurting anything?

    Yeah you can put the same size on all 4 at least for the 18" rims. You can choose to use the wider or narrower tire.
    I think the 17" rims are different widths for front and rear .. someone will correct me if i am wrong.

    My DPO rotated the staggered setup tires. It didn't hurt anything. 235/50R18 vs 255/45R18 is 20mm = 3/4".

    I'm running 4 235/50R18's and rotate them annually at oil change.

    Maybe its the front that is the issue... as in its higher than it should be causing the back to squat?
    She's not leaking any fluids anywhere. I got under and checked and everything is clean and dry...

    When the rear shocks/struts wear out will it cause the rear to sit lower?? From looking at other STS's and pics here mine is definitely sitting lower in the rear than normal...

    Shocks don't hold up a car; springs do. If your car isn't level, your leveling system needs attention.

    Interesting... I think it might be a combination of maybe bad tires and the leveling system...

    Like I said its not terrible. I just want to get it looked into before my warranty expires.

    How can you tell if you have the 17" staggered setup?

    You'd have staggered tire sizes.

    Or, if both front and rear tires are the same size, remove the center cap on one of the rears and see if it says REAR on the wheel.

    Re: 06 STS new to me... Bad rear suspension?

    jonesjacob1, At first I thought it needed spark plugs as the engine was misfiring very slight during light throttle up hill. Changed spark plugs at 63,477 miles . Drove it to Florida from Ohio and had a slight viberation as if I had a unbalance tire or one going bad. Had the tires rebalanced, no change. Have read on this fourm the torque converter could be it. Taken my car to a Cadillac dealer. They said it needed a transmission software update. $130.00 later no change. I guess this was the Cadillac tax that every speak of. They also stated if this didn't work a torque converter would be needed. what a change after a new converter. Car rides very smooth. Danny

    Interesting. Do you remember what the converter set you back?

    Re: 06 STS new to me... Bad rear suspension?

    jonesjacob1, Yes I do. I live in columbus Ohio where there are many transmisson shops. There was one very up front with pricing. $1,000. plus sales tax. The caddy dealer wanted $1800. My car was out of warrenty, but had been in for so much warrenty work that Cadillac customer service was able to cut this in half. For $900. this encludes tax and a free loner car. Taken 2.5 days.

    Re: 06 STS new to me... Bad rear suspension?

    I just had a torque converter replaced under extended warranty. The dealer charged Zurich $569.80 labor, $612.28 for the converter, $17.20 for a gasket and $36.32 for fluid. Is GM# 96042553 a rebuilt converter?

    $1,235.60

    Never had any chuggle. Shifts are silky-smooth. No noise or vibration.
