Best tyre size for track 15x10s

Hi guys,

which tyre size would fit without rubbing on the back of my 96 saleen. Im planning on buying a set of centerline wheels in 15x10 or 15x12 (if they'll fit) but im not sure what size tyre to go for..

these are the wheels im looking at..



To run in the series i want to, i have to use either BFG drag radials or the new MT Drag radials.. MT ET streets arent allowed

these are the new MT's


and the BFG's



ooooooooorrrrrr... do I get a new pair of saleen 18x10s and use the BFG 315/30/18 Drag radial....

thanks in advance for the advice

i think im already being swayed by the MTs....
