What size front drag tire to use with fender well headers?

Hey all,
Just converted my 71 Demon from a 360 to a 400. I am using Hooker Super Comp fenderwell headers. I need to change my front tires due to them rubbing on the headers. I have a set of Drag Lites 3.5 x 15 wheels. Just wandering what size tire I can you use.
Thanks
