QUOTE(jim9146 @ Mar 31 2003, 04:09 PM) Now back to the simple stuff: Isn't Don's advice (loose car, inflate rear tires) just the opposite of what Brad and DD said earlier in the thread? Like B said, either may work. The interesting thing here--tires have a range of pressure where they stick the best. This range is different from tire model to tire model. Some tires (notably the very sticky "competition" tires) work best when they have relatively low pressures, like in the 20s. Other tires, such as many or most "normal" street-type tires, grip best with pressures around 40 PSI or above! Going to higher pressure can lead to a loss of grip, and going to a lower pressure can lead to a loss of grip. Depends on where you are relative to where the tire works best. This is a long way of saying that raising the pressure in the rear tires will often take out some oversteer, but sometimes it can actually add more! It depends on the exact tire. --DD |
