Might rotate tyres too. Question: do you folks with asymmetrical rubber rotate side to side or just let em roll as is?

Usually you can't go side to side with asymmetrical tires since they are directional as well.

Are you sure? I know they have an inside and outside, but I thought they aren't directional. My Michies aren't.

Just depends on the tires, some are some aren't. Pic of the tread pattern?

I would tend to think that if they are labelled inside and outside then there would likely be a Rotation arrow in that sidewall as well. Otherwise what would the purpose be of having the in/out labels in the first place?

Because the tread pattern and compound are different for cornering and water displacement. There's a certain tread design that needs to be on the outside of the wheel versus the design that needs to be on the inside of the wheel.

Even something with a relatively simple tread pattern like the PSS if you take it from one side where the grooves are 'aiming' forward (which I think is typical) and turn it over the the opposite side of the car the inside/outside will still be correct obviously but those grooves will now be aiming backwards.

Maybe that doesn't make a difference and I'm overthinking it though.. but to me that has to affect performance.

But regardless even when the tires are new you put one on one side and one on the other side there going to be mirror image of each other.

On a standard car tire I'm sure that is exactly right and the tread patterns are designed with that in kind, though in any kind of performance in recent years that I've seen they are side to side. Two different moulds to counter exactly that. Hence forward rotation labels on the sidewalls.

Or maybe I just haven't had enough coffee yet this morning :icon14:

There are new PSS -- the Pilot Super Sport 4 S...

i just do mine once a yr.

no. i dont rotate tires at all. not only does dat degrade performance, it can introduce unwanted tire noise. only on all season junk tires on my wife's Fit do i place the better tires on the rear vs the front to prevent any spin outs.

so when i take wheels off my ride, i note on the barrel which corner i took it off of. just a little slit of masking tape and just mark FU and WTF and i know which corner it goes on nxt time. :ugh:

its really da reinforced belts dat is key on asymetrical tires. those belts need to be on the inner side of the wheel towards da center of the car.

motored my STI and had a blast. i faking luv this car mang.. :excited: it is such a joy to drive this car it is unbelievable.

only thing i do is set the throttle to S# (i run stage1 AP) and center diff rear-bias. nothing else, even leave the VDC turned on to maximize vectoring. thing just turns with barely any understeer and no step outs even with summer tires in 18F weather... lol

sounds great too.... until a rock hit da roof :mad: BANG!! :eek:
luckily only a light chip, no dent :ugh: :rofl2: who faking cares, dis is a rally car. little roadrash is OK.

dis is why ive been thinking about just selling the Z and getting an abarth dat ive been wanting since release.. i might seriarsely do it dis yr..

madness lowering springs (2inches+ drop) and datz about all id mod on da abarth. i luv da look of dem 17's dey offer factory, exhaust sounds awesome.
