clearance on tires

guys, when i set my car up i used a 10 inch wheel with a 29.5 by 10.5 tire, now i have 12 inch wheels with a 295-65 drag radial and am worried about the tire clearance. it's about a half inch front and back and tucked under on the top. the car has coilovers just wondering if this is enough or should i drop back to a 29 by 10.5 w tire for piece of mind. by the way am mocking up with old rubber so haven't spent the tire budget yet.

one thing to rememeber is that the radial wont grow like a slick would ......... and you got the proper offset to accomadate for the larger wheel (width) ?
