What are the widest tires I can fit on the front and rear with the base fenders (not fender flares from high performance and cooling package) on the stock/base wheels (not from the high performance and cooling package)

[Saturns]

To keep within xdrive specs. No flares. None ZTK.

Tires
F 245/40R19
R 275/35R19


Wheels
Front
19x8.5
+25
5x112
66.6
Satin Bronze

Rear
19x9.5
+33
5x112
66.6
Satin Bronze

I just don't remember if I had to put 10mm spacer on front to make flush.

This is soooo clutch! Almost identical wheels specs to what I’ve been looking at! Stock ride height?

The Non-ZTK wheels aren't 9.5" wide though, so fitting a 275 might not be optimal.

I have 19" style 893 non-ZTK and they are 9.5 rears

Here are the tire fittings per wheel width

Stock wheels no fender flare are a 19x8 if you got the one that came with a square set up and 225 run flat tire. Generally if the wheel is about 85% or more of the tire width it looks okay. Start going wider than you get bulging sidewalls and it looks off.

8x25.4mm = 203mm/225 = 90%

You could get away with 235 tires on stock wheels, 245s even but the look would be a little off.

The 893 wheels ARE the ZTK wheels.

Not sure, my dealer did not mark them as ZTK on the BOS.

[Baldilocks73]

Yep. Those are the wheels that are part of the ZTK package.

Maybe in the US - here in Canada they don't offer ZTK...I think here it's called "M Enhanced Track package" - it's an extra $3,500 CAD and provides Adaptive suspension + 893 wheels (all of which you can configure separately)
