Had a drive in a 535D - very nice and may tempt me to part with the RS4. However it has run-flat tyres that I believe are VERY pricy [mate is selling a 1 series as he cant stomach £600+ for a set of tyres on a small car]. Anyone know if you can bung standard tyres on the rims?

I think their suspension is, according to BMW tuned to run on run flats.

I would expect that you could change to run on normal tyres, but you should wait for others to confirm

Think i would prefer a runflat over a standart tyre, especially if one did go
Though if you shop around, you will probably find the runflats for less than 600quid per set, worse thing is there isnt much choice in these type of tyres

You can but is not recommended

Handling is tuned specifically for run-flats, and will always be better on them because of the much stiffer side-walls.

Downsides are that ride comfort suffers (doesn't bother me) and I'm now having quite a lot of tyre noise at slow speed after 13,000 miles (Dunlops) but apparently this has been sorted in the newer compounds.

If you get rid of them you'll also have to buy a spare tyre.

I don't know the cost but I doubt there is much in it (I've got 18" "z" rated 275/35s on the rear, they are always going to be pricey)

Look at www.e60.net for more info.

Seriously good cars though, astonishingly good handling and once you've had one it's hard to imagine driving anything else.

Although you can argue that "most" cars suspension systems are "tuned" for the wheels and tyres the car came with.

Yet you see countless cars sporting 18" or 19" or larger alloys and ultra low profile tyres....in effect reducing the damping effect provided by the sidewalll....like runflats.

So Horses for courses


Shop around for tyres, the prices certain places charge vary wildly.
