[Beemer On The Roof]

Evening all, i am sat here this fine evening trying to figure out the best tyre size for my f32 435dx on 19" 442m alloys.

My car has 15mm spacers front and 20mm spacers rear.

I am aware of the staggered setup and believe my wheels are 19x8 and 19x8.5, my current tyres are front 225/40 rear 255/35 and have a rolling difference of 0.23%



The main reasons i would like to go with slightly larger tyres are to look more cosmetically appealing and slightly improve my cornering grip (mainy front end but a little wider in the rear wouldnt hurt)

I am a very spirited driver when the roads allow.

So after trawling the threads in wake of answers i have came across quite a few different suggestions which I will post below, all are within the 1% rolling difference apart from one which is 1.07% (is this negligible?)






Also i did see one guy running this setup but this seems to wide a tyre for a 8.5 wide wheel



Ideally I would like to increase my cornering grip as much as possible while SAFELY showing a little tyre bulge over the lip of the alloy for cosmetics sake.

I will be running Michelin PS4's and obviously as the tyre sizes increase so does the price so i suppose this should really be taken into consideration...

Hopefully somebody with a little experience here can chime in and give a little input.

What tyre sizes are you running and why?

Thanks for reading all, hope i didnt miss anything!
