Anyone ever put 10.5's on the front?

I could see probs with tramlining but clearance shouldnt be a problem.

I was considering putting one of my rears on the front to get an idea what it would look like.

I burst a tyre on the rear last week and it cost me £222.00, i was gutted!

As you can see , a lot of our members have it with no problems.
You just need to ensure that the 10.5" wheels have the correct OFFSET for the X5.

The next time I replace the rubber on my 4.6 I'm going to run 10.5 all around it should allow for longer life and more milage out of the tires do to the fact that you can now rotate side to side and front to back.

It is the feeling that the steering wheel is pulling one way then the other, as the front tires follow grooves in the road. Wider tires will tend to tramline more, althrough it does depend on the specific tire and tread somewhat.

Imagine streetcar tracks (tram lines) years ago, and what it would feel like from the driver's seat as you were crossing the tracks, at an angle close to parallel.

I can see why you'd want to do it for aesthetic resaons, but ultimately you're going to change the handling balance of the car on the limit...ie in an emergency situation.

More front end grip which translates into less understeer which could develop into snap on oversteer...not good!

Thats not strictly true, for example the 10.5's from ACS were designed with BMW and are well within their design tolerances being that the design limit is not the same as the emergency situation in terms of those tolerances and the compensation made by the vehicle itself under the conditions you mention.

BMW, as well as TUV etc approve and fit the ACS wheels and indeed maintain the warranty and insurance as per a factory unit. There is plenty of design and safety information available on this from BMW and ACS.

Although the handling is completely different, in the same way a 8.5's, 16 inch wheel on 265's is, it is not negatively adverse on the performance especially in emergency situations.

Having said that the assumption is that the vehicles set up is the same as the BMW ACS parameters, such as the suspension, springs, height etc etc and that the KDS readings are also within those tolerances set out by BMW and ACS.

If not then your comments may well be more relevant but still not strictly true.

Not sure on the 10.5 on the front look should be ok as long as the rims are not sitting out past your arches or the local plods will catch you.

On those AC wheels the spokes just look far to skinny to offer anything like a decent look/ride.

The 10.5s are fine and well within the arch line, see previous comments regarding BMW and ACS.

I cant account for your taste but with regard to ride I have driven the X with 132's and 168's the ACS wheels are comparable to the 168 ride with the ACS set up. The handling and cornering is better than both. Admittedly I dont know what the ride is like with the ACS wheels without the ACS setup.

I see what your saying but the car comes from the factory with wider wheels on the back for a reason. If BMW spend million$ developing the handling of this car you got to figure they know best.

Fitting the rear wheels on the front (with the rear wheel offest) is not a good idea unless the wheel has been designed for that purpose ie ACS.

You just need to bare in mind that for every mod you do has a reaction somewhere along the line. For a mod to really work things need to be kept in balance with the original car.ie go wider on the front only if you can go wider on the rear .

I am late to the party but figured I might just my 2 cents ...
I have been running 10.5's in the front (ie all 315's all around) for
the past 2 winters/falls and. Handling will certainly change and as it
has been mentioned before it will be much more sensitive in regards to
road imperfections . However it will also change the overall handling to much less
understeer (especially if you have the Dinan Camber kit) .
Dinan actually had considered selling their S3 X5 package with 10.5 in front
but due to availability problems of the Micehlin tires decided against it.

I have a number of pictures up at http://www.janixworld.com/x5/Wheels/
for those interested.

I have a 2000 4.4., could I put 10.5 all around?
