RE: Tire Size
Some members have put a 255/50R16 on the factory rims, but whether or not it works seems to depend somewhat on the tire brand, model, and skill of the installer. 245/50R16's will fit more readily, though either way, they may not perform quite as well as a smaller tire, since the rule of thumb for tire/wheel sizing is rim width is greater than or equal to 80% of the section width of a tire. Using this formula, a tire with a 225 mm section width is about the biggest some people would recommend for a 7 inch wheel. The 245/50R16 is extremely close to the factory size tire in terms of circumference, but you can expect about a 3-5% difference in outside diameter, with the speedometer reading slightly higher than the actual speed. The 255/50R16 is even closer in diameter, sometime as little as half an inch difference in circumference.
