Car Forum / Lexus Cars / January 2009Tire cupping
Does 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 out of spec. Anyone? Bob If you had to align the car so often in 60K miles and they drifted off spec no matter how little, then I would suspect loose suspension components. For instance, if ball joints, struts/mounts and rubber bushings are worn, then those need to be replaced. If tires aren't properly balanced then it could cause cupping as well. You wouldn't happen to have Bridgestones tires on there do you? If you started having problems while things were still covered under the comprehensive warranty, then obviously the dealer didn't fix things right. > Does anyone else have problems with the ES330 causing tires to cup??

The garage wanted to check it, as the tires were not wearing evenly, and starting to cup. But nothing was ever found wrong or out of spec.

SignatureRay O (correct punctuation to reply) Tires were generally rotated every 5 or 10,000 miles. >> Does anyone else have problems with the ES330 causing tires to cup??

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. SignatureRay O (correct punctuation to reply) Ray, 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.. >>>> Does anyone else have problems with the ES330 causing tires to cup??

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? SignatureRay O (correct punctuation to reply) If the alignment is in check and the tires are rotated 5-10K miles, then worn struts or other suspension components should be found and fixed. These include control arm bushings, struts and mounts, ball joints and strut rods (rear). It's too bad these aren't covered under warranty now. Your mechanic should be able to quickly check for looseness by pushing on the wheel while on the rack. etc > Tires were generally rotated every 5 or 10,000 miles. Thanks for the info.. Will check it out next time in garage.. Thanks If the alignment is in check and the tires are rotated 5-10K miles, then worn struts or other suspension components should be found and fixed.
