Here’s my situation. I have a 71 C10, lowered 3/5. I have a chance to buy some 18x9.5 338’s with 255/55/18 tires. The price is great and the wheels are the style I’m looking for…just unsure if these will fit and look correctly on my truck. I looked on the wheels, but I can’t see what the backspacing measurement is. Any help or advice is appreciated. Thanks all
