The timing belt on the SC430, LS 430 engines are good for up to and above 100K miles in my experience from replacing the belt at 128k miles on previous cars, and the belts looked practically new. I believe Lexus suggests the range of about 80K miles. It should be replaced based upon mileage not the calendar.

2010 SC430... Hello SC430 enthusiasts, Has there been a concensus as to whether or not there is a such thing as a smoother, more comfortable RF than the OEM Dunlop sport 5000 DSST? If not, then of the tires mentioned previously, Michelin pilot A/S, Bridgestone Potenza RE-960, and the Pole position, what tire will? I'm still looking at Run Flats like Michelin Pilot Sport All Season 4 ZP, A/S 3 Plus, and Continental Sport Contact 5 SSR, if in fact they may be a better RF than the Dunlop.
