I asked these questions buried in another thread, but I am afraid they will go unseen there...

I just purchased a set of the Toyo RA-1s and I'm registered for the first ever National SCCA time trails event. I'm super excited.
A couple questions about the Toyos.

1) What kind of camber do these tires like? I'm currently running -2.2* up front and -1* in back.
2) What have people found to be a good pressure for these tires?

thanks

 

1) don't worry about camber
2) about 34 psi HOT

These tires will wear a lot faster than anything you have used before. You should rotate them every 2nd session to even out wear between the front/rear left/right. Because you are not running super duper spring rates - nor slicks - I really don't think camber is going to be noticeable to you. Some camber is better than none - that's all you probably have to worry about. Cornerweighing your car will also help even out wear of the tires and improved available grip

Your braking points and slip angles are going to be different too - and they will change as the tires heat up and also as they wear down. - I would try to pay attention to that.

Depending on the type of track you are running on (clockwise, counterclockwise) you will tend to see more wear on one side of the car. frequent rotation of the tires will even things out for you.

don't be afraid to run the tires backwards (even though they are directional) in the DRY. The tread design is directional to aid in water evacuation only - it does not affect grip in the dry

 

Toyo recommends target hot inflation pressures of high 30's to low 40's, and camber of -2.0 to -5.0 degrees.

For best wear, flip them on the rims halfway through their life.
