[QUOTE="Chris, post: 420283, member: 1"] It largely depends on the tire. This is why I always use Tire Rack when shopping for tires, as they list the weight of each tire. Given that the size is equal on both tires, a M/T will weigh more than an A/T tire most of the time. However, an E rated A/T tire will weigh more than a C rated M/T tire most of the time. There's a lot of variables that come into play, so it really depends. Also remember that a 37 inch tire is not really 37 inches. Case in point: My BRAND NEW BFG KO2s are 315/70R17. According to the BFG specs, they are 34.4". I measured them on the vehicle with 35 psi, and they measure at 33.25" almost exactly, and that is brand new with 100% tread on them. This is true amongst almost every tire manufacturer. If you measure those 37" tires, I'll bet dollars to donuts they aren't bigger than 36", but probably closer to a high 35" tire. [/QUOTE]
