Original tyre sizes for 21inch Alpina Dynamic alloys

Hi,

I currently have the following tyre sizes on a set of 21inch alpina dynamics:
Front - 275 35 ZR21 (103Y) - Pirelli P Zero
Rear - 325 30 ZR21 (108Y) - Dunlop Sport Maxx Race

Can someome tell me if the above are the correct sizes, correct brand of tyres and also the model of tyres (recommended by Alpina)?

On previous cars, i have always preferred a wider tyre.
The rears look ok, but the front looks like they could be wider.
So would the following fit (and still be recommended):
Front - 285 30 ZR21
Rear - 325 30 ZR21
Again Brand and Model would be much appreciated.

I do around 2k - 3k miles per year in the car, so ride comfort is not really an issue.

Also Camber suggestions would be good, as i would get this all done at the same time i get new tyres.
I have 20mm spacers on the front and 20mm spacers on the rear.

the size you suggest is only 10mm wider at the front and the profile will look a lot smaller than the back because of the width. could you not go another size or two wider ie 295/305 at the front and if necessary reduce the spacer width if that is necessary to keep within the arch. It would make your tyres look more of an equal profile and give you the width you desire. A lot depends on your wheel width if it will accommodate those sizes. Just something to think about

Hi

If you check this link for the Alpina 21" alloys they recommend 285/35/21 front and 325/30/21 for the rears

Correct sizes are as above buddy.

285/35/21 and 325/30/21

I went with the 275 on the front as at the time didn't have any other option due to rarity of the tyres lol.
