Well, they go effen hard
BFG T/A's are made to look good, which if I'm being honest, is what they do well.
Unless you've experienced them in the wet, not much can compare to them.
Have no info on Cooper Cobras which I think are available in the sizes you're looking for-so can't comment.
You can get some big Pirelli's I think bigger than what you want.
Try Antique tyres in Melbourne, they can probably help you.
