Correct Wheel Offset?!?!? Want some new ones!

OEM rims:
17x7J 24.2 lb 50mm offset
15x6J 16.25 lb 45mm offset
center bore 54.1mm
bolt pattern 5 x 100mm

The center bore is the hole in the center of the rim. Obviously, it has to the be same or bigger than OEM. If bigger, the space between the rim and the hub forces the wheel to be supported only by the 5 lugs. This is called lug-centric. Some say this is ok. Others will want spacers to fill the gap so the car's weight is supported by the hub, called hub-centric.

Offset: a lower offset means the wheel will move outwards, away from the engine. Looks better but too much and the wheel will stick out the body and spray all sort of road grime on to the body. Google "wheel offset calculator."


You'll have to buy 4 sensors to work with the car's TMPS. Otherwise, the indicator light will be on full-time. It'll be about $350 + labor, on top of tires and rims.

Personally I like wheels by Five Axis. They look smokin' hot and they're reasonably priced.

If you haven't already you should search PC to make sure 17" fit on non-V models. Something about steering motors are different between models.

 

The existing sensors couldn't be reused? I didn't think they were sized to match the rim..

 

Probably. If the OP buys the rims and/or tires online then it has to be unmounted and then he has to find local labor to install.

Since I need separate rims for winter, my mind set was fixed on a separate set of TMPS sensors. I don't want the hassle to remount tires and sensors twice a year.

 

The existing sensors will work, so you will just have to swap them onto the new wheels. I did for mine and no issues. Of course if you want two sets of wheels with sensors (winter and summer, for example), you'll have to buy another set and have the dealer reprogram each time you swap out the different sets of wheels.

 

I assume the TMPS sensor in the 15" wheel is stick on the wheel somewhere. As soon as we unmount them, we should see the sensor stick on the wheel, right?

 

The sensors are part of the wheel valve assembly and look like this:


You'll pretty much have to remove the tires to access the sensors.

 

it you run a 8" wide rim. the perfect offset would be et45 fronts and et35 rear with a 225-40 rubber. that would give you a flush fitment front and rear with no rubbing. im not trying to threadjack, but i have some lightweight 18" wheels/tires for sale in the FS section. heres the link if your interested
