I've been trying to get to the bottom of this one for a while and keep getting conflicting answers. My Esprit S2 has the original Speedline wheels and newer, correctly sized tires. What tire pressure should I be using? The Lotus info states 18lbs Frt, 26lbs Rear. I've been told that is way too low and was only that pressure due to the tires available in 1979. Newer tires need more pressure. I've also been told that the Speedline wheels are the reason for the lower pressure and 30lbs in a tire would wreck them. Then again I've been told that the pressure spec is all part of the Esprit handling and suspension aggregation and not to mess with Colin's original intent. What is the correct pressure to go with? Your feedback is appreciated.
