What is the recommended tire inflation pressure for a Cooper Discoverer A/T 31X10.50 R15 LT tire?
Answer Jim, Recommended inflation pressures depend on a lot of things – among them are the load on the tire, the tire size, the conditions a tire will be operated in etc. The load on the tire is mostly about the vehicle it is on. Any particular vehicle can accommodate a variety of tire sizes – and each size might require a different pressure. In theory, this would make the pressure recommendation very difficult to do. However, they’ve made it easy: On every vehicle sold in the US, there is a sticker commonly called the tire placard – that lists the original tire size and the proper pressure for that size. The placard is usually located on a doorpost or in the glove box but sometimes it is located in the trunk or on the fuel filler door. BTW, it doesn’t matter who makes the tire or what pressure is listed on the tire’s sidewall, if the tire size is the same as the placard, then the pressure listed on placard is also appropriate. One word of caution: Some trucks use tires with the letter
