I would like to know who is running P-metric & who is running LT-metric tires. I ask this because I am running P-metric tires which have a max. psi of 35 lbs pressure. So, therein liesthe culpret as to why my ride is not as comfortable as I would like it to be. I am going to go ask if I can exchange them for an LT series tire which has a higher max tire pressure. So when I inflate to ST specs the tire will not be at its max, therefore giving a better ride. I came to this conclusion after talking to ToddZ about this issue. :D

Stock P255 as of right now, But going to LT255 or 265 when the time comes...

But you already knew that...

bf goodrich 31X10.5 mud terrain got rid of that goodyear crap that came on the trac you can keep them good year that is

:cool:

 
LT's will definitely ride harder. I ran a set of Dunlop Rover RV LT tires on my 95 Explorer, and the difference between those and the P-metric version of the same tire was very noticable. The LT had several extra plies in the tire construction to increase the load rating.
 
Actually the LT's will ride softer because you're not maxing out the psi. I really didn't realize the diff. until now, but the tires that originally came with our ST were LT series General AmeriTrac A/S, with a max. psi of 44lbs., which rode great. P-series = passenger tires which are intentionally designed to run at lower air pressure; whereas LT-series are designed to run at a higher max psi, so when you run them at lower air pressure you do get a comfortable ride. The TOYO's that I've had over the past couple of yrs. put the hippo (side-to-side) rocking back into the ST's ride, whereas before I was running LT series tires with Monroe reflex all around & the ride was very good. I strongly feel that the ST is designed for LT series tires because of the weight of the truck, and I am confident that going back to an LT series is just what is needed to get my comfortable ride back. :D
 
Hey Rodger, you know that rocking your talking about, well with my RF blown shock My truck rocks now too.....LOL :lol:

I think it is 42 lbs/psi, but I run them with the inflation listed on the door. They bounced too much at the higher psi. Now with the new shocks, all wheels stay planted on earth where they belong. :cool:
 
Remember, running tire pressures at the max is not the best thing to do. Tire pressures are set by the manufacturers for a reason. They calculate the weight over the wheels and the maximum weight that could be over the wheels. That is why the OE pressure is higher for the back tires because the bed is designed to carry a heavy load.



Running your tires at the maximum PSI will cause them to wear out sooner in the middle. I have a set of snow tires to prove it. The middle of the tire tread is almost bald while the outside of the tread is like new.



Running LT tires will not make it ride softer. LT tires are designed for vehicles that are LT and the Trac is not a Light Truck.



A P series tire will ride the best with the proper pressure of air inflated into that tire. I now run my tires 3 PSI higher then Fords recomended pressures. If I am hauling alot of weight in the bed, or on a long trip, I will inflate them closer to the max pressure. Under normal driving, I am at about 3 PSI over the recomended pressure.

Tom, I do understand what you are saying, but both the TOYO Open Country A/T's & H/T's have a max psi of 35 lbs. So, that is why I want to go to a TOYO tire the has a higher max psi, and the LT series for TOYO is the only way I can do that. Plus, I don't want to loose any money on the deal since I've only had them for 1-1/2 wks. So, in a way we're both right. I feel the difference between P-series & LT-series varies between manufacturers. I looked up the max psi for a Michelin LTX M/S, and guess what it is 35 psi. And, the max psi for a Pirelli Scorpion STR is 44 lbs. Go figure... While the ST is certainly not a light truck it does weight almost as much as one, definately more that a say, Ford Ranger. Think about it.
 
A Light Truck is an F250. the Trac weighs nowhere near that of an F-250. An F-150 is not even considered a Light Truck. An F-250 will weigh over 7000 LBS, if not over 7500 LBS.



Dad's 2003 Ranger weighs about 4500 LBS. he had it weighed to prove to me it wasn't that heavy, he was wrong.
