It is ok to run 10" tires front and back. It is not recommended as far as the rim size and tires, as they are just outside the range for 10" rims for both 275's and 315's. However, this is the exact set up I am running with the Nitto NT05's and it works for me. My car is lowered about 1.5" also. I did buy these rims to run 285's all around but couldn't find any tires in that size that I wanted to run. I think you may run into rubbing issues running a 305 up front.
