How would you rate the condition of this tire and why? What percentage of tread would you consider to be remaining? This is a 235/40R17 Toyo RA1.

Thanks.




I also have this in the tire forum, so admins, please excuse the double posts.

Please note, I don't pretend to be any kind of professional racer or be able to blast any time attack records to pieces (except for those of slow Maxrev ). All opinions welcome.

I rate it Rogaine...for bald.

 

Garbage

 

Probably another track day or so if you flip them.

 

agreed. they probably shoulda been flipped a little earlier to get the most life out of them, but i'd still flip them and run em for a while longer. once the main tread disappears on ra1 (and the 2 center grooves are all that's visible) they still have a decent amount of life in them. don't throw them away just because they're "bald."

 

With that much tread left on the inside, it tells us that you need mo' negative camber. As for flipping them, I think it's too late to make it worth the cost to do so. Preferably, you'd like to do it before the tire gets to that point.

As was mentioned above, I'd hardly call that tire bald- maybe "friction-shaved." I remember reading two viewpoints on when RA-1's are at their grippiest: 1) new and freshly shaved and 2) right before they cord.

 

I'd use it for another day or two! RA1s work well all the way to the cords.

 

Would you rate it at 50% treadlife remaining?

 

Probably more like 30% overall usefullness left.

 

If they were shaved they're fine.. if they're that bald from full tread they're gonna be down on grip..
