It was great:) i filled up to 40, get on the interstate and the barrier is on my right, everything is giong smooth. Then the barrier ends just as a huge gust hits. Suddenly my car is slammed and I get pushed several feet to the right and nearly into the other lane:) couldnt really gauge the effectiveness today:)

That high air pressure you are running greatly decreases the stability of your car, one of the many reasons the car was engineer with 32psi in the tires for a reason, so if you are having stability issues, first thing I would do is drop the pressure down to the correct pressure

Hey, just to start out, this is def not a personal attack against you, but I would really like you to support that with some data or some logical explanation, rather than just having me take your word on it. In particular because of this thread

where we have people talkinga bout 60psi and such.....

Anyway I did some reasearch though now im doing more research and I cant seem to find anything that supports using max pressure. Anwyay, alot of people say that toyota speced their tires for comfort and performance, however, by pumping them up a littl emore you improve performance and decrease comfort--just as they did with spring, etc...and so that is the general premise I came to believe for a little while. Though im not sure it is true. In further defense of that position everyone always stresses never to be below recommended pressure. that means that factory recommend pressure is essentially the MINIMUM pressure right? so how could the minimum really be any better than the max? just a thought...

Also, I have had my pressure right at the recommended pressure up until i made that post and I have had a terrible problem with handling...though....

there might be a particular reason.... I went to a dealership a while back and they initially said I had some rough road force and needed a new tire, then they never called me when it was supposed to have come in, i called them. they didnt write down which tire so they retested and said everything is fine, then another dealership said everything is fine, and I just dont have that much time to fuck around with the dealers. Anyway I really want some new fucking tires...lol damn it but stay on topic, join in to that PSI conversation, just dont get caught up on the 60PSI part, im with whatever you have to say in that much at least.
