re: Tire pressure on truck tires question.

I looked it up because it was odd to me why a truck would have passenger tires. Some had the P-rated tires, and some had LT tires. Yours would be C load LT tires, which should be standard on a 1/2 ton truck. D should be on there if you tow.

I also saw that the passenger tires were only lasting like 20k on F150s. This happened to my dad twice, and I've noticed it happens to my mom's GL550 with P-rated tires also. That leads me to believe they are not designed or suitable for trucks and SUVs

Eta: Reading comments online from multiple lead engineers at different tire companies, they do not advise getting P-rated tires on a truck. This is a scam used by Ford to get better mpg and better ride, and the engineers hinted at it being unsafe
