Cant say I have every come across staggered tyre sizes on the Range Rovers. Not sure why this is as the like of BMW X5s do have wider rear wheels and tyres

Is that why they put 20" wheels on? '08 RRS TDV8
I converted my diesel RRS to run on an environmentally friendly mixture of caribou fat and baby seals oil

20" are ok Mike

I HAVE A SOLUTION!!! I LL GET THE 21 s front wheels are 9X21 rears are 10,5X21 but my tire dealer told me that ve can apply 275/35/21 size tires for all wheels and it will not make any problem.What you guys think abut this? Or a will go for FRONT 285/35/21 REAR 325/30/21 and also for this sizes of tires i m confused if they will fit my 21 inch wheels as width i need your help guys

thanks

Whatever you buy, you want the same rolling circumference front and rear or you risk transmission damage.

If you want something that looks like a BMW X5, buy a BMW X5.... 2012 SDV6 - it's missing a couple of cylinders
2008 TDV8 - it was a labour of love and is much missed

the difference is about less then 1 percentage i m not sure if it will damage or not ? about the x5 believe me if i like it i ll go for it but i m really happy with my ride but the wheels is something very important to me thank for your help KML4EVER

A bit late to the party, but 5-6 years ago ran a staggered 21" wheels setup for at least a year on my 2006 Sport - before being bitten by the off-road bug... - without any issues whatsoever. My wheels (currently collecting dust in my garage), made by Cargraphic in Germany, were sized 10x21 front (ET46) and 11.5x21 rear (ET52), with 275/40ZR21 tires in front and 315/35ZR21 in back. I could have gone with a lower profile set of tires front and rear, but I wanted to preserve as much of the original comfort as possible, so I picked the beefier set. The setup looked great back then, and no trouble with rubbing anywhere, even though the overall circumference of those 21s was slightly larger than stock.

Finding 21" tires is tough, and they are usually very expensive. If I were to do it again today, I'd probably bypass the 21" size and go with 22s, much easier to find a wide selection of tires in that size.

Thanks alot for the info and the pücs it helped me so much.i m confused about the center diff because the front and the rear will be different sizes will it make a problem? And if i go 275/35/21 for all wheels with 9x21 front and 10,5x21 rims what will gonna happen? So confused  KML4EVER

As long as the overall circumference of front and rear tires wrapped around them is the same (yielding the same number of revolutions per mile), the center differential won't care about different rim sizes and you will have no issues. You can use an online calculator to figure out if the combination of rim width and tire size you are considering will be an appropriate match for our cars. Here is a good one: http://www.rimsntires.com/specs.jsp

In your specific example, if you are getting a wider rim for the rear, you would want a wider tire to match, as I don't think a relatively "narrow" tire such as a size 275/35 would fit well over a 10.5" wide rim. You could probably go with a 315/30/21 for example, should be a good match for the fronts and stretch nicely over the wide rear wheel, giving you the look you are looking for with no adverse effects on transmission and differentials. Of course, this is assuming the wheels you are considering have the proper offsets and internal clearances for the Sport. For example, the 21" wheels I have would not fit a Supercharged Sport (with larger front Brembo brake calipers.) 

The closest match will be like this, front 275/35/21. Rear 315/30/21 and the circumference difference will be % 0,48. Will this difference cause any problms? KML4EVER

No. 

But why would you want a staggered set? 91 BMW 850CSI

For looks, what else? If there is another reason to buy 21, 22" or larger aftermarket rims for a morbidly obese SUV, staggered or not, I am all ears.
