Are 15 inch wheels any better than fourteen inch wheels?

There are millions of 14 mini trucks out there, no one is going to dump the 14 molds. What they will do is drop the 14 line to a lower shelf tire brand, ie. Hercules or Cooper. Now finding a 14 wide is going to be a hunt. As for larger tire patch, that deals with the OD of the tire, not the diameter of the rim. Less sidewall is not always advantageous. On a freeway cruiser, a rubber band 35 series 20 inch tire with the accompanying 20 inch wheel mass is not the best combination. I watched a Volt with its low profile/ low resistance tires run over a 3 inch curb taking a driveway a little short at about 10 mph. Popped the tire outright. Watch "Blues Brothers" and watch that big Monaco bounce over a median at 30 mph. Try that with 18's and 40 series tires. So...any one know where I can find some 235-70R14s?:steering:
