Rubbing on 20"

So I installed 20" rims and have 245/35 tires on the front but noticed a noise from the front. Found out that there was only mm's of clearance from the tire and the little bolt+thread that sticks out from some arm in the wheelwell.

It dug into the tire and wore a deep groove... How do I go about grinding the thread off? Any specific files or... ?

you need 30 profile tyres on the front and 25's on the back.

Very surprising to hear this. I tried a number of different brand 245/35-20 tires on SL - none had any rubbing issues. (255/35-20 tire does, however, rub against that bolt, but there was no noise at all - just an extra groove in tire's tread as a result of rubbing). What's your wheels' offset and tire brand? Was noise heard immediately when installing these wheels/tires or at some point later?

Maybe if car is lowered.

On a stock hight SL however, 245/35-20 front and 275/30-20 or even 285/30-20 rear - present no issues at all. I tried above combos on a number of stock hight SLs - no rubbing issues at all. This is the first time I hear that 245/35-20 front rubs on "that" bolt. But the OP is not replying with details.
