I'm with Rebel1, my ideal Cobra tyre sizes in 15" are 245/60 & 295/50. That's what I fitted to my last Cobra.
15" tyre choices are extremely limited again now.
I bought Yokohama Avid S/T 245 & 295 in 15". A very good street tyre, wouldn't hesitate to recommend them, but unfortunately yokohama must not have been selling enough, as they are now dropped.
Or you could get some better straight line traction and fit some street Mickey's to the rear.
