So I was digging around in my rim/tire stockpile and I found an interesting combo. I have a 2003 buick century, caddilac rims, and 1 ton truck tires. The truck tires fit the caddy rims and the caddy rims fit the century. The tires are about 4 inches taller, but the same width and a whole lot heavier. Getting going and slowing down would be off topic, but how would mileage do at cruise speeds? This would give me an overdrive of, well, something crazy, and a really stiff ride, but what do you think would happen? I have my own tire changer now, so it is easy to try. I just want to know if it is a totally stupid idea.
