17x9 RuF front rims with 235/45/17's Rubbing

Thought I would solicit feedback before taking the knife to the car. Its a mint original 88.

I have installed RUF rims, my fronts are 17x9 with no spacer, tires are 235/45/17. I'm getting some pretty serious rubbing on the front bumber wrap around section at about 75% full lock. Also contacting pipes in left side wheel well (driver side for statesiders) but looks like I can rearrange the pipe supports to fix this.
Whats the best way of dealing with this?? Smaller tires or modify bumper wrap around rubber sections?

Cheers

Would be interesting to see what offsets/backspacing your wheels have. I'm running similarly sized tires (Nitto) on the same sized Zuffenhaus wheels. No rubbing. Though looking at the rubbing pattern on your fender, it doesn't appear as if just a few mm of offset difference would matter.

Can you just not do full lock? Or try smaller tires or tires of another brand (might have a different enough shoulder profile to avoid rubbing)? Trimming the fender seems like more than I would want to do for originality's sake.

edit: Here's what I'm running.
Front – 17x9.0” 5.68 backspacing, ET 30mm
Rear - 17x11.0” 6.18 backspacing, ET 17mm

Full lock goes on ok, it just hangs on the fender about 3/4 way through. The tires are Kumho KU31's. Offsets on the wheels are ET17.7 on 17x9's

Agree, I do not want to start cutting things up, the cars to original for that.

Cheers

How close does it get at the back of the fender and rear portion of the wheelhouse?

Yeah, you could change the caster and move the tire back in the fender well.

If no spacers left, you ran out of room = wrong backspacing.

Kind of what I was thinking.

Either the wheel offset is wrong pushing the wheel out too far, or the a-arms are bent, or in the wrong position from sloppy bushings, mounted wrong, or pan damage, pushing the wheel too far forward.

And as Gumba mentioned, tire diameter is a little on the large size. Looking at a chart for Kumho Ecsta XS, the 235/45R17 is 25.4 " dia., for comparison a 245/40R17 is 24.7" dia.

I am running the same tire size (235/45) and really should be running a 40 profile but was a bit scared to run such a low profile with nasty roads or a manhole cover that could really damage the wheel.

I shaved the aluminum bumper support on the right side as that is the only point where my tire would "catch" on. I have a picture I can post if it help.

I am running a 235/40/17 on my 17 X 9 Ruf Speedline Classic. This is the tire size recommended by Ruf for that wheel. I have no rubbing issues at all. As WinRice points out, the overall diameter of the 40 series tire is 24.7" which is very close to the oem 16" tire it replaced.
