Ok my 300sd 85 has geostar tires are completely bald in the side front and rear. i know the tires are cheap but i was not sure how the car would perform when i first bought it.

know where i can find 20-70-14 tires with an H speed rating? i have found one brand that fits the bill. DORAL? some Japanese brand, i think.

now to my real question

why are the tires bald?

symptoms?
the back end is not stable on curvy wet roads the car feels and has like it will break loose at any second.

bald inside edge of all four tires. pretty consistently

rear end very low, with a couple of groceries it drags the tail pipe coming into the driveway.

with too much weight in the trunk strange mini vibrations in the rear end occur.

took it to eurospec(awesome) in asheville and they say shocks are good and springs are ok and they never replace them.

we put it on the lift and they say the front end bits, bushings, ends are ok, some are " getting close"

make a drive down to me, and I'll look over your car. I'll bet you have trailing arm bushings going out, LCA bushings going out, and upper control arm bushings going out.
you could also have a bad diff mount, it'll cause the rear to sag, and tilt the tires in at the top, wearing out the inner in the rear.

When I had inner Front Tire Wear it was the LCA Busnings rotted out.

Inner tire wear? Check all suspension bushings for play and alignment. Typically too much toe, in or out, will destroy the inner tire... more so than camber.

will do,thanks for the reply. fronts are actually worn on the inside and out. what seems odd to me is that the inside wear is so consistent.

Inside and outside? What tire pressures are you running?
