Just bought a sc430 2005, hard to handle on the freeway moves with every groove and bump is this the tires or the car?
I bought my 05 in Dec of 09. Only 9,000 miles. I had the same problem. I was told by others it was the runflats. by 11,000 miles one of the tires was to the thread . I opted to replace them all with regular tires. HUGE DIFFERENCE!.. You take a chance with no spare but there is enough room in the trunk for a donunt if you are concerned. I'm taking the chance. Been driving 41 years and never had a blow out. AAA or Lexus is only a call away if you have a flat.
