Hey guys. Iv been in the market for tires for quite some time now and I just got a big-o check for helpin roof a house :thumbup:. Anyways, my buddy highly recommends Mastercraft Courser MTs. He loves everything about em, and I love the price so far! Anyways, I was lookin on the internet and at the sizes they have. I found a cool site that compares your tire to the new one and says how much taller and wider and how far off your speedo will be. It says a 315/75R16 tire will be 2 inches taller. Is that from the bottom of the tread or the top? And it says itll also be 2 inches wider. Is that from the "bulge" in the middle, the rim, or the tread? I wanna measure everything out to make sure everything will fit ok and drop to a smaller size if need be. The 315/75 was an example... I hardlu doubt theyll fit but its worth measuring! Thanks guys!
