  Goodyear Tire & Rubber Company, named after Charles Goodyear, started in 1898 with a mere $3500 down payment on the first plant. On the 29th of August, 1989, Goodyear officially became incorporated. In 1926, Goodyear became the world's largest rubber company and has a total of $20,000,000,000 in sales as of 2010. The Goodyear Wrangler AT/S, one of Goodyear's all-terrain style tires, comes in both light-truck (heavy-duty) and passenger (light-duty) tires.
  
  

Sizes

• The Wrangle AT/S comes in several different sizes so that it can fit a number of vehicles. The passenger-rated tire has only one size option, P265/70R17.

Weight

• All tires have a maximum weight capacity at a specified inflation rated in pounds per square inch (psi). The weight capacity is the amount of weight each tire can safely carry for a given psi. The passenger rated tires have a maximum load rating of 2535 lbs. per tire at 35 psi. The LT tires are designed to hold more weight. The maximum capacity varies between the different sizes. The LT215/75R15 can carry 2095 lbs. per tire at 65 psi; the LT235/75R15 carries 2335 lbs. per tire at 65 psi; the LT275/65R18 carries 2535 lbs at 50 psi to 3415 lbs. at 80 psi, depending on the load range; the LT275/65R20 carries 3750 lbs. at 80 psi; and the LT275/70R17 carries 2600 lbs at 50 psi.

The LT215/75R15 can handle 5.5 to 7 inch wide rims; the LT235/75R15 can handle 6 to 7 inch wide rims; the LT275/65R18 can handle 7.5 to 9 inch wide rims; the LT275/65R20 can handle 7.5 to 9.5 inch wide rims; and the LT275/70R17 can handle 7 to 8.5 inch rims.

The LT rated AT/S's section widths vary, depending on the tire size. The LT215/75R15 has an 8.5 inch section width; the LT235/75R15 has a 9.3 inch section width; and the LT275/65R18, LT275/65R20 and LT275/70R17 all have an 11 inch section width.
