Good eye!

Keith can spot that too, and amaZes me by telling people their wheels are on backwards. It's almost always a service station or tire shop error; certified Nissan mechs just don't do that.

I can look right at them and not tell the difference.

What is the difference between front to rear ?
Is it rim design or offset ? These rims look to have a cooling design ?

I believe they're talking about the wheels rolling in the wrong direction, which *could* mean the tires are, too. The design on the wheel spokes is functional (when they roll the right way), and directional tires would be mounted to roll in the direction of the arrow on their sidewall. If tire shops rotate the tires improperly (side to side, instead of front to rear), then all the tires would be rolling 'backwards' and the sculpturing on the spokes would no longer serve whatever purpose it was designed for (brake cooing? Wind noise? brake dust dispersal? I dunno).

Rolling radial tires in one direction, then reversing them to roll in the opposite direction, used to cause major separation of the whole tread from the tire, sometimes with disastrous results. Not sure that still happens today, but the tread of most tires today is designed to throw water outward and backward and to grip corners better in one direction. If made to roll the other way, they not only lose that advantage, but actually become worse than properly-installed worn tires would be.

AirJockie could give us a better description of this than I can ~ he's a real tire Guru.

Thanks Frank
I was referring to the wheel. It does appear the tire is directional.
The black Z next to it seems to be missing a lug

Frank is right about the tires. TT's have a staggered stance out of the factory.... the rears are 8.5" and the front are 8.... so technically the rears need to stay in the rear (unless u want a funny looking car lol). only way to properly rotate the tires is to dismount and remount onto the other wheel.

The wheel's design is a cooling factor.... supposed to draw more air into the rotor when mounted properly. the straight up portion of the spokes should be at the front of the car....with the "pointed" portion at the rear. hard to explain in text

More important to have the tires rolling in the right direction. if not youll have poor traction/performance.
