I have a 2010 BMW X5 3.0 d M Sport E70 2010 model and want to fit the winter tyre and alloy set I had for my previous X5 E53 but I would need hub adaptors , that I cannot source on the web. Will the 18" 255/55 tyres be ok and if I cannot find adaptors will new alloys of 18" be ok for the E70 , so that I can get the live out of the tyres?

Hi Westy,
You should have no problem at all....Why not drive to the place you want to get them and ask the seller if you can try one just to check, and then be 100 percent certain?

Although alloy wheels are softer than steel, chrome and aluminum wheels, there are no reports to confirm they should not or cannot be used. wheels are dented due to impacts such as hitting a curb or getting in an accident.

okay, 235 is the tread width 45 is the profile(the distance from the wheel to the road)ZR is the speed rating(over 120mph)17 is the wheel diameter.so to get the same tread width 225 would fit(cheaper than 235)45 needs to be thicker cos of 16" not 17" wheels and 1"=25.4mm 75 would be the choice.because winter tyres are designed for speeds less than 70mph "R" would be suitable.
all together 225/ 75(or 85) R 16.....SNOW TYRE/WINTER TREAD.
PLEASE LEAVE FEED BACK.

It sounds like some of the steering components are bent, also check the camber.

Watch out for a vehicle thats had a 2 inch or greater upgrade in tyres. These things chew up the inner sides of the rear tyres pretty savagely, the standard tyres (eg a 235/65/17 for a base model) relies on having sidewall flex and low(ish) tyre pressures to spread the weight and wear on the rears. Lower profile and or higher pressure will chew out rear tyres.
Also look out for the drivers door handle, its called the 'carrier' its weak and wears out, a genuine BMW carrier fitted in a BMW workshop can cost you over $600 all up. You can get OEM parts for $100 on Ebay, From the same factory and packed in same box and then make whoever is fitting it quote you on hours and dollars before they start. You drive away under $250 AuD
Keep up the oil changes, air and fuel filters and you will have a vehicle to be proud of, Fantastic motoring, Enjoy.

16 is the rim size and most modern ones will take 215 tyre. Of more concern is the PCD (which dictates how holes line up) would suggest a trip to a breakers and get 4 from any VW Passat (or other) of similar age

THERE ARE 3 ITEMS YOU NEED TO CHECK SO BEST TO CHECK WITH AN ALLOY WHEEL SUPPLIER FOR THE SIZE SUITED FOR YOUR CAR

• PCD THATS THE DIAMETER THAT THE STUDS ARE FROM THE CENTRE OF THE WHEEL
• THE ET ( OR E40 AS YOU STATED ) IS THE OFFSET OF THE FACE THAT MEETS THE HUB FROM THE CENTRE LINE OF THE WHEEL, IF WRONG, THE WHEEL COULD HIT THE SUSPENSION WHEN TURNING HARD, OR SMASHING INTO THE WING ON A BAD BUMP
• THE TYRE SIZE ( PROFILE SIZE, "50" 40 "45" ECT IN RELATION TO THE ORIGINAL RIM SIZE SO THE SUSPENSION IS NOT AFFECTED
• 
  

what design are they, two thing could be doing it, if the obviouse touching has already been investigated, one is the design, if the spokes/hub sits out further than the rim than the outer of the rim they could be catching the wind and making some freaky noises, or if the center dishes in then maybe they are "loud" tyres by that i mean do the tyres have wide grooves, directional etc, high performance tyres are in principle very noisy. hope this has been handy.

does your car wiggles?
if it does check the tire pressures, make sure the are balanced.
check also brake clearances, make sure also to balance them.
