Post by BobRay,
The car steers perfectly with no vibration or fluttering...
The scallops appears across the entire tire. I did increase the pressure by
3 or 4 lbs, believe 35, and tires now seem to be wearing out in the center,
which I guess is to be expected. Believe I will have to replace the tires
within
the next couple of months. It is the 17" tires, so not too many choices.
Did come
with Michelin and I replaced with Goodyear.
Not sure what to try next..
Post by Ray OPost by Ray OPost by BobDoes anyone else have problems with the ES330 causing tires to cup?? I
have a 2005
model year, and have now ruined the 2nd set of tires with a cupping
problem.. Vehicle
has about 60,000 miles, and has been aligned about 4 times. Never really

Unfortunately, front wheel drive vehicles are more prone to unusual tire
wear patterns than rear wheel drive vehicles, and some brands and tire
models are more prone to wear problems then others.
"Cupping" is generally caused by worn or damaged parts, especially worn
struts or shock absorbers, which is not likely on a 3 year old car with
only 60,000 miles. Do you get any vibration or fluttering in the
steering wheel?
When you say the tires are "cupped," do you mean that they have a
scalloped appearance across the entire width of the tire tread or just on
the outer or inner edges?
If just on the outer tread, try increasing tire pressure by 5 PSI cold.

Scallops appearing across the entire tread width usually indicates worn
shocks or struts or an over-inflated tire, although I doubt if 35 PSI is
enough to cause cupping. With worn struts or shocks, the wheel and tire
bounce more, and as the wheel rebounds back to the pavement, some rubber is
scrubbed off.
Look at the struts for signs of fluid leaking, and do the old-fashioned
bounce test. If the struts are bad, you would probably experience a
wallowing sensation on rough road surfaces. I doubt if bad struts are the
cause, but it never hurts to eliminate all possibilities.
After that, I'm out of ideas without looking at the car. Have you tried the
Lexus dealer or a Toyota dealer?
