As mentioned in the title, I was wondering if anyone here is running a wider-than-OEM Falken FK-452 on their OEM 18" rims.. and if so, what size are you using up front and in the rear? Any issues with rubbing or the VDC system screwing up?

I'm probably going to get these tires, and I would like to go slightly wider, particularly since people seem to say that these tires have almoste no protective lip and provide poor rim protection against curb rash.

Thanks!

 

Bump?

I was thinking of going with 255/45/18 in rear and 245/40/18 up front.


OEM Michilin PilotSport specs are as follows:

225/45/18 Michilin PS Front: 25.8" Diameter, 8.8" Section Width
245/45/18 Michilin PS Rear: 26.7" Diameter, 9.6" Section Width



OEM-Sized Falken FK452 Specs:

225/45/18 Front: 26.0" Diameter, 8.9" Section Width
245/45/18 Rear: 26.7" Diameter, 9.6" Section Width



Plus Sized Falken FK452 specs that I'm considering:

245/40/18 Front: 25.8" Diameter, 9.5" Section Width
255/45/18 Rear: 27.1" Diameter, 10.1" Section Width


Do you guys think I'll have issues with VDC running this setup? I could also consider going with the 255's in the rear and the 225/45/18 Falkens up front, since the falkens seem to run about 2/10" taller in diameter than their equivalently sized Michilin counterparts.


Does anyone have any idea about what the formula for the difference between front and rear tire rotation/size is that Nissan/Infiniti actually uses to calculate when to kick off VDC? I think I remember reading somewhere on another sight(my350Z?) that it's something like a +/- 3% difference from stock circumference is acceptable, but I'm not sure if that's an accurate claim by those guys or not.
