I've recently bought a 1991 Silverado Extended Cab, Long Bed to use for Home Depot runs and to load stuff into this truck for transport that I would not like to put into my nicer SUV or sedan. The truck came with LT tires from the factory in size 245/75-16. The previous owner upgraded the size to 265/75-16 which many upgrade to for a slightly taller and beefier tire. The truck has two Dunlop A/T Radial Rover on the front and two Jetzon Revenger A/T in the back. Both axles have plenty of tread. However, from my understanding both of these tires don't perform well in the rain or snow, something that's important for me in a full size truck with weak brakes during inclement conditions. DTD is having their Presidents Day promotions on tires and I thought about buying four new ones for this rig. I don't want to spend a lot but at the same time want the performance. I have decided to downgrade from the LT tire to a regular P tire for a smoother ride. From my research many people put the P rated tires on their trucks and many trucks come from the factory with P rated tires. The LT tires have reinforced sidewall with more ply to carry heavier loads and for towing. I do not intend to carry any heavy loads or will I ever tow anything. I also want to go back to the stock size of 245/75-16 to perhaps get a slight bump in gas mileage and to reduce some sluggishness. I'm not sure these things will be achieved but it's worth a shot. The P tires are less expensive than the LT tires so I've narrowed it down to the General HTS60 which are selling for $105.50 per tire with a combined rebate of $135, meaning these will be shipped to my door for $287 after rebate in size 245/75-16. The reviews are great and these will probably perform better and ride better than the tires that are on the truck now. One thing that bothers me is that the door jamb sticker on the truck recommends a 45 cold pressure psi on the factory LT rated tires which have a capacity of 80psi if needed. The P rated tires have a maximum recommended pressure of 44psi on the sidewall as many of you know. If I run these at 44psi cold pressure or close to it, I'd be running them at the maximum recommended pressure of the tire but slightly lower than what GM recommends at 45psi for the LT tires. Would this be okay to run the P rated tires at their maximum mfg. recommended tire pressure - to be as close to the 45psi GM recommended pressure or is it simply too dangerous especially for the summertime as the pressure will rise with temperature on this heavy rig? I intend to recoup some of the cost of the new tires by selling the old tires on Craigslist as they all have a lot of tread left. Is my logic about the tire size, performance of the Grabber HTS60, downgrading to a P rated tire that has a maximum allowable mfg recommended pressure of 44psi skewed for my needs? Should I pay an extra $51 and get the LT rated HTS60 with the lower 50k mile treadwear rating and settle for a harsher ride? The Continental Contact LX20 also have rebates on them and from some reviews look to be good tires but the reviews for the HTS60 seem to be better suited for a full size truck. Thanks in advance!
