Awd ?
 

As with the GTR....... How does the the AWD system function having a rear tire height that is .06% taller than its front tire? My first guess is that this isn't enough of a difference to matter but it works out to be about 5 revolutions per mile of difference. Enlighten me please. The reason I ask is because I want to put a set of 370 wheels and tires on my wifes Juke and I think it has the same AWD system as the GTR......

Probably works because it's just .06% taller.

I'm sure Nissan has it all figured out with the GT-R.

All the tires should be the same in an AWD vehicle. I had to put a different size of tires about .06% taller also on my old lady SUV and the dealer was refusing to install them stating it was AWD.

Anyway I had to proof them wrong after a long wait and argument, long story.

The big difference with the GTR is the way the AWD is set up.


The ATTESA E-TS is pretty unique, and during the vast majority of the time, ~98% of the power is going to the rear wheels. You will actually see guys throw ATTESA codes when running mismatched tires, or if they are driving in such a way that they are seeing a pretty even tq split.


On a car like a WRX, you have a viscous coupling F/R that will overheat and grenade itself if you mismatch F/R. On the GTR, you are looking a slightly increased clutch wear, and it really is only ramping up wear when it is actually engaging AWD. The combo of a very small difference combined with how infrequently power goes to the front wheels means that you really don't see much extra wear.

The GTR is powered by FRIEND COMPUTER. Literally everything in that car is computer controlled. I got to play around with one at Carlisle and the interior (I really want to call it a cockpit) is just ridiculous.

I have heard stories (3rd hand) of people with GT-Rs messing with wheel sizes etc and having problems but who knows.

.06" is within the same parameters as tire wear or under or over inflation. No biggie.

and it's not like you're driving perfectly straight all the time either.
