17x15 inch wide wheels!!!!

[Yenko boy]

Basically im having my 69 camaro mini tubbed with dse's kit as well as having the rear fenders rolled. So I'll have 6 extra inches of clearance, so im really thinking about putting 15 inch wide wheels under the car. Are there any problems I should be aware of anybody know of a tire company that makes tires big enough to fit on massive rims like these? Thanks guys.
