[Chocolatero€]

I've been reading everywhere but I couldnt find a final answer.

I have a 120d with Xdrive and for winter tyres I just got this square setup:

BMW 16" Styling 377 7J with Hankook i*cept RS 2 (W452) 205/55 R16 94H

I read good reviews about this tyres so I hope it would be fine for this winter.

My problem since I have this car are the summer tyres.

I dont know why my xdrive car came with a staggered setup, because if the car is AWD it does not make much sense.

Wearing RFT (bridgestone s001) the car have no grip on wet and the comfort is absolutely awful.

If Im not wrong this setup looks like :

225/40/ 18 with 7.5J (front)
245/35/ 18 with 8J (rear)


So basically my question is : Should I keep the staggered setup or I can go for a square one?

Can I have a square setup with those wheels?

I assume a square setup with 225/40 would be the best option, but Im not 100% sure.

Its also cheaper tho.

Im thinking about Michelin sport pilot 4 or Continental conti sport 5.
Whats is the best option?

Thanks and sorry for this long thread !
