About LT235/85R16 Tires
You have been prepping your rig for an off-road adventure, but when it comes to choosing truck tires, you quickly lose track of the options and become completely lost. Your hunting buddy says you need LT235/85R16 tires, but you have been puzzling over that code and you still do not know what it means. Fortunately, it is not as complex as it first appears. The "LT" means these are light truck tires. If there were a "P" instead, then that would indicate a passenger tire. The three-digit number indicates the width of the tire in millimeters. Narrow tires tend to grip well in mud and snow, while wider tires offer better handling on normal, dry roads. The first two-digit number indicates the aspect ratio, which is not a value in millimeters but is actually the height of the tire's sidewall expressed as a percentage of the width. Higher aspect ratios are often better for off-roading, as they provide better shock absorbing capabilities. The "R" indicates these tires have a radial construction. Finally, the last two-digit number indicates the internal diameter. With this information, you know that LT235/85R16 tires are 16-inch light truck radial tires with a sidewall that is 85 percent of the 235 mm width. Such tires, and tires with many other specifications, are widely available among the large inventory on eBay.
