"P" or "LT"? What's the diff? - 23/06/03 11:22 PM
Lotsa threads on tires and tire sizes got me wondering...
I searched the web and found a lot of good info on tire sizing, how to 'read" a sidewall, etc... But there's one question I can't find an answer to.
All the websites I found on how to read tire sizes simply say: "A 'P' rated tire is designed for use on a passenger car and an 'LT' rated tire is designed for use on a light truck." They don't say why, or what the difference is.
So, what's the difference? If I put "P" tires on my light truck, will it suddenly want to park at the mall, and shun other trucks? Will a Buick that's been fitted with "LT" tires suddenly desire to hang out with F350's at construction sites?
Seriously though, I would guess it's got something to do with sidewall strength and/or max load-carrying weight limits, or maybe tread aggressiveness/depth. Anyone know? And by the way, as long as I'm asking questions, would an "X" be considered a "light truck" since it's on a truck frame, or are they talking about rigs like F-250's and the like?
