tire pressure

[jt]

Recently got a '05 (blue), had an '02 (silver) a few years ago , sold it and missed it.........what tire pressure are people using on the '05? Car door says 30 psi , dealer said 42 and tire says 50 max psi?

F*ck!!! i want an s2000, it's always sad to hear someone just got an s2000 and don't know jack about car, especially tire pressure. I'm gonna guess this fool is not gonna break the car in accordingly and later complain about the car using too much oil, because he f**k up his piston ring. Ohh yeah if the tire say 50psi max than run it at about 35psi during summer and 40psi during winter.

With your new car you were supposed to get all kindza paperwork including a mostly blue little book that had all kindza spec on the car in it.
Take a look at the back of the book. Voila! Index! Anything you wanna know about your car is in there.
Now to get to the tire pressures: The spec in the book says 32psi. They MEAN 32psi. History lesson: (and don't ask me how I know this. I'll be forced to lie) back in the "old days" you could get away with "tuning" your tires by adding or subtracting a relatively large portion of the recommended psi. In those days the hottest tire was a 70 series and had a sidewall that rivaled the tall buildings that Superman could leap over. It's still a dooable method if you're runnin' mud bog tires on your jeep.
But the low profile tires on the S2s (and their cousins, bikes like the R1 and all the rest of the sport bikes) can afford very little deformation before they either damage the rim or worse . . . part from the rim. The tire is made to remain very close to the shape that you see when it's in the parked state. It does it's job best in that shape. It's most efficient in that shape. Like everything else on the S2 it's been designed to within an inch of it's life so that the S2 could be the canyon carvin' little demon that it is. And when something gets that refined there is very little room for any deviation.
Stick with the remommended 32psi. It'll make you smile.
Good luck.

Somethin' that doesn't really mean anything to your current tire's pressure but may be of interest: the old high-sidewalls were actually a small part of the active suspension of the old cars. The tires took a major part of the hit out of each bump. (Considerin' that the original cars started out as road-going tractors, the first "roads" bein' nothin' more than what was left over from the horse n' ox drawn carts, that shouldn't come as much of a surprise)
But the extreme low-profile tires that we have on most of todays hot vehicles are a wee bit too sophisticated to be doin' windows, so to speak. They are almost 100% meant to stick you to the road. The similarly sophisticated suspension systems that we enjoy today take care of the rest of it.
Hope I didn't bore you with the history lesson but sometimes that's the kinda stuff that triggers the best ideas.
Hope you're enjoyin' some top down weather. Be well.

Mine is just an '02, but I run 32 PSI all the way around in the stock tires.

That last post's from someone who's Xin' the car guys. It's worth payin' attention.
Be well.

Actually, when AutoXing, I am on race tires and the pressures are different front to rear. It depends on ambiant tempurature and surface conditions.

Same here.
