On my project beater (90 geo prizm) I put on two used tires already on rims from a Sentra. The bolt pattern is the same (4x100) but the big hole for the hub in the middle is bigger on the new rims. They bolt on flat and fine, clear the brakes, and have a similar offset. The lug nuts and seats on the steel wheels are both conical-- the lugs are therefore centering the wheel nicely. Torqued them down very evenly and methodically so the wheel would be "pulled" to center correctly. Is there anything I'm missing that makes going lugcentric a bad idea? I'm most interested in safetly, less ultimate balance/comfort.
