Minimum Tire Clearance?????

[ZZ3ElCamino]

I saw a thread about this a while back, maybe someone can point me to it because I can not find it. Otherwise, can someone help me? I am currently taking measurements in anticipation of my Moser 12-bolt purchase. I have 12" of space in the fender well to work with, and I would like to use a 275/35-20 in the rear (10.9" width) leaving me ~.50" of clearance on each side of the tire. I don't plan on taking my car to the track, but may drive the car hard from time to time. Is this enough clearance to account for tire buldge, etc.?

Thanks
