Today I had new rear tires installed. A family member has this size tire on his 914-6, and it looks great. So I got the same. 225-50-16 on 7” rims.
They clear the fenders (which had been rolled by PO). Passenger side has plenty of clearance at 1/4”. Driver side not so much, just enough to slide a thin cardboard between tire and fender while bouncing on back of the car. All is fine in a straight line. But Passenger side starts rubbing at right-hand turn. See pictures below to spot the rubbing location (paint starts to blister a little). Should I try to stretch the fender a little? Or... Is it possible to create some room by adding a shim to change the camber? Thanks for letting me use the collective brainpower. Attached thumbnail(s) |

That's a big tyre ,surprised there was any clearance @ all,I did max camber and pulled both sides a little with 205/50's.
Max negative camber helps and the result shouldn't cause too much excessive inner tyre wear ,in my case its no really excessive and I'am running no shims at all. |

I suspect that fender has been pulled a bit prior to this. I’ve never had a tire wear problem and I’ve run maximum negative camber since forever. As you go in to corners, you gain camber. This is where your rubbing is coming from. As the tire moves to positive in corners, your gap which is good when static becomes 0 And rubs. Max negative camber in my experience in a 914 is just a bit > 2*. We aren’t talking about stupid “stance” look. You can tell, but it isn’t ridiculous. Handling, with the right tire and tire pressure is dramatically improved. That isn’t a bad thing, since these are momentum cars for the most part. You can also raise the rear a turn if you have coil overs. I have a problem with fender pulls. Camber can easily be reversed. That tire and wheel combo can be changed. Reversing a fender pull, not so much. We need to start treating these cars like they are valuable because they are. |
