Hi all, I have upgraded my 16 inch wheel to the M193 wheels OEM,
the car is still smooth with the 18 inch, I have installed the new rims with the old tires, planning to change them later, however today for the first time my car got very slippery on the road when pressing a little break on wet road, I already have the ABS fault but it never did such side slip on my 16 wheel, it is the tires ? Are the 18 more stable for handling ?
I have installed before 18 wheel (M6 18 wheel) but the car was not soft at all, so I removed them, but those 193 style seems good to my Z3, shall I keep them and only change the tires ? The tires are only two years old..

And what tire sizes are best for the 193 wheels on my Z3 ?

Also are the 18 better in handling from the 16 ?

Thanks,
