CX tires on the fuji SS=1mm clearance

The Cyclocross tires are affixed. However some problems were encountered. Since 30c is the absolute max I can put on my frame(technically not designed for it) I did have some clearance issues. The new tires had to be perfectly true to produce miminal rub. I am left with only 1mm to spare on all sides between the tires and the frame, this is even when I added about 1.5-2mm of spacing by taking a wide enough metal tube and banging it into my rear triangle and front fork. The rear brake had to be removed as the brake housing was rubbing into the tire. So now I have a fuji track bike with only front brakes and now CX tires.















I do like the tires as the ride is a little more comfortable on rougher terrain and eats pots holes in the road a little smoother, but there is the occasional tire rub when the rim is stressed when cornering.
I do have the feeling of impending doom on a daily basis because i will only have front brakes and I will also have to keep my rims perfectly true at all times.
It will be interesting when snow and mub is caked on the tires. The Bianchi Roger can't come soon enough.
