*** My Tires Are Getting Destroyed ***

I have a 2005 545i and my tires are getting destroyed!

BMW sport suspension - factory
Front tires: Falken FK-452 245/30/20
Rear tires: Falken FK-452 285/25/20
Wheels: 20' DPE R06

The wheels are aligned and I rolled my fenders - BUT the inside part of the tire is getting worn out until air leaks out.

How can I stop this from happening to new tires?

Its related to CAMBER from what i understand - someone who knows more will chime in I'm sure
but this is common on some BMW's where the inside of the tires wear more due to a camber being off

Remember, incorrect toe setting will eat tires more than anything. Almost if not all cars on the road has negative camber.

Have another shop check/redo alignment. Not all shops or mechanics are equal.

Have another shop align the car. My guess is the camber may be fine sitting still, but when you turn its getting out of wack.

Your car is set at a fairly negativer camber in the rear. It's how a 4000 lb car can be made to handle as well as a BMW. Negative camber causes wear on the inside edges of the tire. The fact that you've chosen to put 20's on the car only serves to exagferate that wear.

I suggest taking the car to an alignment shop that is familiar with BMW suspension setups and ask them to realign the car and to set the rear camber at it's least negative value and still be within spec.

Putting the stock 18's back on will help as well.

It's not just the rear tires. Both the front and rear tires are rubbing on the inside. What should the camber be set at for the front and rear? Since the tires are rubbing, should they be at zero camber or slightly positive?

Does anyone have actual Hunter alignment specs to prevent rubbing for my car?

Stock sport 545i 18" conti DWS and 20k shows less than half wear.

i had this problem when i put my M5 wheels on. it was due to the tires being too wide and aspect ratio being a bit higher for m5. mine are only 19's

Ninjapotamus - what was your tire size and brand? Were you able to fix the problem?

What should be the correct tire width and aspect ratio for 20" rims?

idk correct sizing for 20's but i think your main problem is ma be the 285 width. idk what others run

tires that were rubbing were 255/40/19 front and 285/35/19 rear pirrelli pzero rosso

i replaced with factory size of 245 35 19 front and 275 30 19 rear

I have a friend with the same exact car, rims, and tires and his tires are not rubbing. He has H&R coilovers though ... and I have factory BMW sport suspension.

i am on factory sport too. mine were rubbing on passenger side. i thought it was weird and i am a bit disappointed as i was looking forward to rocking the bigger tires, + the replacement cost me 1300 since i had to do it in a pinch and couldnt wait for tires to be ordered.

Ninjapotamus - were your tires rubbing on the inside ... and after you did an alignment?

I have an '04 E60 with sports suspension and 17" alloy, and same problem inside would wear off similar to rear tyres i.e. rear tyres wear off quicker than front, so when my rears are near gone, my front is okay but the inside of the front is gone. My tyre fellow said it because when turning, I should not take a full swing at the steering and my wheel alignment fellow said it is because my front tyres have low pressure compared to back ones. I don't trust any one of them, but yet to find out what is the real cause of fronter tyres wearing off from inside...................

Had the same thing occur but only with the rear tires and, yes, attributable to the camber. Rear tires, as a result, wear twice as fast as my front tires and because tires can't be rotated the "warranty" mileage is typically halved if honored at all.

You can try to have the alignment shop dial out your camber as much as possible to minimize the negative camber effect. However it will change the handling characteristics of your car slightly. I will say that the falkens I've put on my BMWs and Lexus tend to wear pretty quick on the inside part of the tire.

a week ago I replaced the wheels and the tires on my car with 650i rims and m6 tires
255/40/19 at the front
285/35/19 at the rear
front ones are rubbing a little it seems like I need to pull out the front fenders a little (which I dont know how, correctly)
but looking at these specs, should I be aware of the same problem or no? if my car has the right alignment will it be fine or do I need to downgrade the tires?

If the tires are rubbing against the strut -- most likely the spring perch on the strut body -- then tweaking alignment settings will have no benefit. So first order of business is to determine where the tire is rubbing and then try one of the below fixes (which will potentially cause a new problem) until you solve the problem:

rubbing on inside of tire -- add a wheel spacer (5 to 15mm), switch to coil-over suspension (which typically have a much smaller diameter spring and give more tire clearance).

rubbing on outside of tire -- remove wheel spacer (if you have one), increase negative camber, flare fenders.

rubbing when wheel turned to extreme right or left -- reduce negative camber, switch to a lower profile tire, reduce tire width.

If you can't completely solve a rubbing problem, you may need to return to a stock (or near stock) tire size. These cars were designed for certain tire sizes and wheels (diameter, width, offset) and straying too far from stock sizes will cause rubbing -- there is just no way around these limitations.

its rubbing outside of the tire and its only when there is a bump on freeway at speeds of 60mph+ and when there is a big bump or pothole on the streets, other than that it seems fine, I did kind of rolled the front fenders, it worked a little but seems it needs to be pulled out a little more.

If you look at an E60 from the rear, the toe-in camber is quite noticeable. Increased wear on the inside edges of the tires is happening by design.

You may be able to convince your mechanic to align the tires with a slightly less extreme camber setting. This will affect the car's handling academically, but if you drive it like 90% of us do you may never notice.

Welcome to a heavy ass car with power which still is a noble sports car. The e60 eats tires due to power and negative camber for the handling. I had a e60 for 6 years and the same wear pattern happened. I had 4 different brands of tires as well as running winter set for the enter time. Drive with any pep the tires will fade away.

Looks like too much toe to me.

Camber is NOT usually the issue with wear like that

My rears have looked like this and the alignment/toe and every other measurement was spec. Does the OP drive spirited?

Same thing just happened to me!

What did you end up doing??

And if you set it up, not factory spec, what specs did you use??
