I have a 2004 Chevy Silverado Ext. Cab with 4WD. I still have the original tires on it- they are Firestone Steeltex LT245 75 R16's. The sticker in the cab (in the door frame) states that I should use LT245 75 R16s inflated to 50 PSI cold. I have 60,000 plus miles on these tires and will need a new set for winter. I have been pricing out some new tires and noticed that their P Metric counterparts are less expensive. I do not tow anything (even though I have a towing package), and I rarely haul heavy loads. I understand the differences between P Metric and LT, however I am not sure if a truck set up for a LT tire could use a P Metric. I have been told that the factory setup for my truck is made for an LT tire and it would handle differenly with P Metric tires. Any suggestions as to what type of tire I should purchase?
P.S.- I do not care about the ride quality of the truck- its a truck! BUT I do care about safety and I will not put P Metric tires on if they will compromise safety! Thanks for any suggestions.
