While running 18 inch Rotiform spf.

Can anyone tell me a proper tire fitment? I'm seeing 245/40/18. But I'm going to be running a staggered set up of 8.5 in front and 10 in back
Thanks

We can't tell you if they will fit without the offsets, but you can run 245/40/18 in the front and have the same rolling diameter on a 10" wide wheel by going with 275/35/18 and be off by 0.5% or a use a a 255/40/18 in the rear, you'll only be off by 1.2%. General rule is to keep the difference within 3% on quattro. If you need to go with a 265/35/18, it'll be off by 1.6%. All of this comes down to your offset, the look you want (stretch or square), the camber, and your drop.

Do you have FWD?

Sorry I meant to say 8.5 front and 9.5 rear and I'm FWD. I imagine the tires dimensions are going to be the same you listed. The back tire I am going to have stretched a bit

1010tire.com ...helps a lot and explains a lot in understanding rolling diameter ranges to keep your speedo accurate...also, consider the brand of tire as some tires have a curvier side wall than others which creates a different look and adds/subtracts from fitment issues.
