Hi, I'm due all four tyres very soon on my 3.0sd X3. I've read that it's best to buy the Pirelli star rated tyres as are fitted now, or face transfer box noises and faults! A full set for my 19" rims is circa £700

from tyre leader. I can get the same size, mid range for half the price. So, options are invited from y'all.
Cheers

I have an X3 running 19" tyres, I opted for all the same size tyres and makes all round, even though I have the staggered setup.
The rims were 8.5"j and 9.0"j so only 1/2" difference in wheel widths.
According to tyre / wheel width calculators on the internet 255/40/19 was suitable for both width rims, so I went for them all round. All my transmission wind up problems went away.
Also you can have any make you choose. Without needing to worry about * rated tyres.
And at half the price.
