New tires,Horrible ride. WM need help

[Trash man]

My mom got new tires one time and they left the lug nuts loose. By the time she got home 2 nuts had fallen off and were rattling around in the hub cap. The other 3 were barely on the studs. She was very lucky.

The left side will tend to tighten as you drive. The right side tends to loosen. Before 1971 I think all Chryslers had reverse threads on the right side. (I hope I don't have that backwards. Those are some pretty old brain cells.)

You really should check them.

drivers side of the car was Left Hand thread. so that they would tighten as they went down the road. right idea, wrong side

I have Kumho's up front (245-50/r16) and the ones in the rear are The Sumo's (255-50zr16).
So could it be that the front and rear are different?

Never was a big fan of two different tire brands on a car. It's like putting on a Nike and a Reebok sneaker. It's going to feel weird.

Alright so, I went To get my car's Alignment done and Sure enough it was all out of wack. Not Extremely but the Caster Was off in the rear b/c of the Control arms (My Error) and the Toe was off a bit on the front....

There is no "caster" on a solid rear axle. The only thing that can be altered in the back (without bending the axle assembly ) is the thrust angle. And the thrust angle would be off if the LCA's were not equal length.

Well From what the guy explained the Driver side tire was pushed back more then the Pass. side tire. All he did is shorten the Driver side Control arm and sure enough got straight. I dont think you can adjust the Thrust angel without an adjustable Torque Arm no? I mean it was not a huge change he made. It was like .15 Degress off. He got it down to .03 degress. Please correct me if Im wrong (Which Im sure I am.)

Oh neither am I but My front tires were still good. Im going to get the matching pair of tires in the next 2 months. It could just be that the fronts and backs are different and thats causing all my issues but I dont know.

Your Right Fred. The Thrust Angle was Off. Sorry for my ignorence.

When you say its pulling. Is it pulling to the right slightly and only on certain roads. Because my ss did it. When i first bought it i thought that it was a problem but the wider lower profile tires will do that on cupped roads from tractor trailers etc. It even stated that in my supplimental manual that the car would occasionally do this on certain road conditions. Just a guess but could be what your feeling.

No my car pulls to the left. At times its almost gone but Its just about 98% of the time. Im guessing the Thrust angle might be still a bit off. Its very very light load that it takes to make it go straight. I dont know if that .03 degress be the cause of this.
