All right now that the burb is on the road, I need to throw more money at it. I want to get new tires. I have 2 255 70 R16's that are American Prospector A/T's. It was 300 for two and at the time I just needed two for the rear of my 2 wheel GMC pick up. Is it worth getting two more of these for that price or does anyone know of any GOOD semi-aggressive tires that I could get 4 for between 300 and 500? If it is possible I would like to get larger than 255. A friend of mine's dad has 285 70 R16's on his stock suburban with no rub??
