Pics are hard to see what is going on... the first 1” of tread is close to the lip yes. The offset is little two far out on the wheels he has 2” of room between the frame rail and inside of tire... his slick tire setup should have more offset on the whee bring it in and inch there is nothing to worry about will bring it inside the lip and there will be plenty of clearance from tire to lip... pretty sure the plan is to run radials on these wheels in pics radials don’t grow.... also moving rearend back any further will take away from why a “a body” works as well as it does in my opinion correct me if I’m wrong but isn’t that why u see 400,000 a body’s at the track with snubbers and ss springs they just plain work beings of wheelbase they are like a damn altered lol
