nobleartjim Posted September 25, 2006 Share Posted September 25, 2006 My 2003 LS430 has low profile tires--that pick up every ripple in the road. Does anyone know what is involved in changing to regular-sized tires? Quote Link to comment Share on other sites More sharing options...
Robert Young Posted September 25, 2006 Share Posted September 25, 2006 My 2003 LS430 has low profile tires--that pick up every ripple in the road. Does anyone know what is involved in changing to regular-sized tires? My 2006 LS430 has a similar problem, although I'm mostly irritated by the "booming" noise from the OEM Dunlop 5000S 245/45-18 size tires. I've noted on the "Tire Rack" site that the Dunlop SP Sport Maxx and the Michelin Pilot Sport AS tires get better reviews for noise. A higher aspect ratio tire might also help and I've noted that 245/50-18 are around 1" larger diameter (fits on the OEM 18 - 7.5 rim, not sure about clearance to body and approx. 4% speedo error) and that 235/50-18 are about the same diameter as the OEM tires and will most likely fit. You also might find another owner willing to trade the 225/55-17 OEM tires and wheels, when I boought my car I couldn't find anyone that had the base wheel / tire combination in stock.
