RT660 255/35/18 front fitment?

The RT660 tires that I ordered came in last week. Comparing the width with MSS, it is almost 3/4' wider if not more. These tires are wide. I recall seeing someone on this forum mentioned that 255/35/18 rubs a little if used as front tires. I plan to use these 255/35/18s as front tires for my 128i. Currently, my car is completely stock since I bought it a week ago. So, no suspension mods or camber plate yet. These tires will be mounted on Apex EC-7 8.5x18 offset 45.

Eventually, I will do the suspension mods. But I want to track the car as is just to baseline it first.

Question: will they rub? Do I have to roll the fenders? Do I need to wheel spacers. I haven't mounted these tires yet just in case they don't fit. If not, I will use them for the rear and buy a set of 245/40/18 instead.

For those who have used RT660 255/35/18 fronts, please comment. thanks

You will need large camber (-2.5) at least. You will need spacers. You will need narrow coil overs (not conical springs like stock suspension).

You will likely still rub with all of the above.

I'm running 255 square on 17s, never tried it with stock suspension. RT660s are way wider than any of my previous tires so I had to carefully select parts (spring and spacer) to go with my struts along with a lot of camber. 245 square was much easier to fit.

Thanks bnace10 and spidertri. I’ll exchange them for 245/35/18, or should I go with 245/40/18.

Given that I have stock suspension setup, do you even think 245/35/28 will fit. Maybe I should go with 235/40/18 for now and wait until I have the suspension done and go with 247/40/17 square configuration like many folks on this forum. These rt660 are wide.

Just had my tire shop mount my newly purchased RT660's and when I compared them to my RS4's they are 0.70" wider per tire.
They are both 245/40/17. I have not tried to install them yet on the car but my RS4's were barely fitting so I don't think these will fit. I have stock suspension with just camber plates and 2.7 deg camber front and 2.3 in rear alignment.
I will try to install them over the weekend.........
