OK, I put these Asanti AF112's on, wrapped in BFGoodrich 285/35ZR/19 (Rear), and 245/40ZR/19 (F).
Tight turns, cornering, no problem- but, if a hit a minor dip in the road (however unnoticeable) at speed, there is this terrible (but less than 1 second) scrubbing sound that emenated from the front of the car...

I don'tknow if it's the tire scrubbing the fender, or the bottom thing that hangs down on all cars, scrubbing the asphalt.

So, can anyone tell me if these tires are too tall for the car? I thought these tires met the max width requirements for this car. Anyone with the same size tires and a scrubbing problem that they eliminated?

Sadly I'm damn-near certain it's the tires... I never had this problem or heard this sound with the stock 16's on there...

Flat roads- no problem...

Damn...

Looks like Tire rack recommends 275/30/19 ?, and 245/35/19 (F)...

Anyone gone bigger/wider/taller?

Looks like a .48" sidewall height difference. .97" difference in overall diamater, and 3.03" circumference. (Front)
.68", 1.35", and 4.27" difference (rear)

And, over stock (225/55/16), 1.11" overall diameter, 3.49" circumference (Rear), and .98" (OD) and 3.05" Circumference (Front).

Damn those inches...

Yup, those tires are too tall. You're running M5-spec tire size/ratios.

Generally, those are the right size. What's the width of your wheels?

you can try rolling your fenders, but +1 those sidewalls are too thick.

Yep, the rear is fine-but the fronts are problematic... What does rolling my fenders mean?

The front wheel is 8" wide w/3" lip, rear wheel is 10" wide, w/ 4" or 5" lip.

there are some metal part(front it is alumium) that you can roll using rolling machine to make as much space as possible.. but looking at the size of that tire, it wont do anything...

so best way to fix is just get new front tire for 245/35/19

also if you are going to lower your car, you have to change the rear one as well...

i bet you if you have 3 people in the back seat with few heavy stuff in the trunk will make rubbing noise from back as well

Seeing that you have a MY2004...i had the same problem with my 2005 until i had my shocks replaced at 65k miles...no more rubbing on dips.. what your feeling your car probably bottoming out. PM Trinity guys...they r the ones that got me the parts, install, and alignment

Check the area of the lip of the fender (under the wheel arch) if it's rubbing there it will be obvious - you have a Silver car so you will see black scuff marks. Based on the scratching noise you describe I don't think it's rubbing there, it sounds more like you're rubbing on the inside fender liner. This you can check by removing the wheels and looking for abrasions in the inner liner, I suspect you have them on front and rear since the rear tire you have is way larger than spec.

Thanks... I've never had a car old enough, or long enough to have to replace shocks (We're at 71K on it right now)- so I had no clue at what time we could/should expect them to need replacement. I was thinking that might've been the case- but was hoping it wasn't. We never had that problem on the stock 16's, but on these 19's, she's rubbing on dips. If I see the dip in time, and slow down, there is no rub, but if the speed limit is 40, and I hit that dip at 40 (Scrub).

But, on tight turns, high-angle drive ways, pulling in and backing in. No rub.

There is a decent amount of clearance on all 4 tires- so I was reall surprised the first time that rub happened.

I know it doesn't sound good, but, what are the risks of doing nothing? Is there a chance of damage to our car?

Damn... I didn't want to have to buy new tires...

Risks of doing nothing include: Premature tire wear where it's rubbing (kind of like the tire rub in NASCAR). With rear tires that tall your speedometer has GOT to be off by a few MPH. Also, if the rear tires are rubbing then you can also damage hubs, bearings, suspension components, etc. Moving parts usually don't like being jerked to a halt, even for a split second.
