I just received my a set of rota p45's and i am in the process of purchasing tires and rolling fenders.
I am wanting to know what size tires i should purchase for a set of p45 18x9.5 +20 offset all around. Also if anybody knows how much i will need to roll my rear fenders and if i need to roll front fenders at all. I run coil overs and have a pretty aggressive stance on small 17" rims (as seen in my sig).

I don't think i will need spacers to fit. I would check myself for fitment but my car is getting a new engine management system and a tune a few hours away so i am not able to fit test in my garage.
Any help or advice on this issue would be greatly appreciated.
Thanks
