Running Directional Tires Backwards

[67rally]

I've done it with Bridgestones.

There are two factors. Is it raining? Directional tread will not be happy in the rain backwards. You got that handled.

Can the carcass run backwards? I would call Nitto on that but it is usually a non issue.

Thanks Donny. I haven't had good luck with Nitto customer service in the past. I won't call them again.

Last time I tried to get an answer out them, they couldn't give me a straight answer on the phone. So I sent them a series of emails trying to get a baseline psi recommendation for the Nitto 555's at an AutoX event...they finally said that the 555's were a street tire, and to use whatever psi I felt most comfortable with and they wouldn't recommend running a lower pressure than for daily street use or something like that.



Just figured I'd ask for advice from people who have actually driven their cars on a track, I can guarantee that Nitto will say they don't recommend running their tires in the wrong direction if they can't recommend changing tire pressures.
