buying new tires for my drop

[camshaftgsxr]

as my truck sits the wheel and tire combo looks good and works fine, however the front tires are flush with the fenders, im running a 15x8 wheel with a 275/60 tire in the front right now and im wondering if a 245/60 or a 255/60 would fit into the fender, the wheel lip is an inch inside the fenders inner most lip, would either of those tires bulge off of the wheel or look funny?

i hope this pic gives you an idea of my predicament
