So flipping is only good on unidirectional/symmetric tires so that you run them on the other side of the car? Can't you do that with the specs with the same effect?

 

basically.

on most tracks you run clockwise, so you have more right turns than left, so the majority of the wear is on the outside of the drivers side and inside of the passenger side. when you flip the directional Z1's from DS to PS you are taking the worn outside of the tire and putting it on the inside of the PS, where most of the wear happens on that side.

if we had uni-directional tires (like BFG R1, R6 or the like) we could keep the tire on the wheel and just move it to the opposite side so that the worn outside edge of the DS would be on not so used outside of the pass side instead of the inside that sees more wear.

hope i 'splained that correctly.

 

why cant we just flip the wheels with z1s? i thought it was just rain performance that would suffer.

 

So basically your telling me, we're still going to be wearing the same part of the tire no matter what?

This seems technical, where's Kenny...

 

Hey, look who showed up. Hi Kenny!


I still think the tire is really only meant to work in one direction. My concern would be the way it dissipated heat when going the "wrong" direction.

 

thats exactly what I said. you can, but by doing that we lose the major wet traction advantage these tires, along with our AWD system, have in the rain. after doing 2 half-days in the rain and passing virtually every car out there, including all out race cars on rain tires, that is an advantage I'm not ready to give up just yet. if the track is going to be dry then sure, flip the tires and run them backwards... but I'm lazy and really hate switching wheels so I probably won't. lol.

yes. and who is this Kenny character you speak of...

 

haha, perfect timing. i would guess there is more to it than rain traction, i always figured a few hundred miles of street wear to even out the tired couldnt hurt

it would greatly complicate my rotation scheme though. With the open front diff, i get some extreme deltas in tire wear

 

I hear what you're saying and honestly I'm just going off information people have told me. they are people I trust, but that doesn't mean they are correct. if you are that worried about it rather than taking advice from some tool on the internet why don't you look it up ya dam self.

 

just wait till you start driving hard.

 

im one of Dan's pool boys.

this is what ive been up to the golden path

The wear is still heaviest on the outside of the driverside wheel, at least of you're driving NJMP. That place (Lightning more so that Thunderbolt) puts a hurtin on that driverside. The lightbulb especially is just constant loading on that tire.

 

Thats some pretty technical info, you would probably have to go to Dunlop to get that, even then I doubt they're gonna tell you...


I wasn't asking you, btw. I was just putting that out there...

 

^ you would think that info wouldn't be too hard to come across...

 

in case anyone cares, this is what the driverside tire looks like after 6 days of tracking. I did rotate them front/back after 4 days.



and this is the pass side



pretty big difference in tread depth.
