There was a good article on tires going around a few years ago and I copied it and have it. If you'd like a copy email me at dqdick10432@yahoo.com The short version is that you can judge a tires reserve capacity by it's weight. Marathons weigh 35.4# each. G614's weigh 57.5# each. A lot more in material and belts in a G rated tire = more safety for you.
