I've read enough - I'm in and Im splitting the difference. Drove about a mile down the road first thing this morning and set 'em all to 39-40. Thanks for the tip Prometheus!Prometheus said:... do i raise the tire pressure in my tires higher than the manufacturer's recommended numbers.

LOL. I just checked mine on Sunday after reading this thread and they were the same...almost 50 in the front and about 48 in the rear (they were cold too). Put them to 40 all around.

Ok, too low of pressure and what you say is correct. After many years of racing sport cars, checking tire pressure was critical to getting the best handling out of the car and tires. I always found that if I went a little too high on tire pressure the cars handled like it was on ice, because I was getting less of a contact patch on the road. The tire was bowed out some what due to the increased pressure. You are probably are getting better gas mileage due lower rolling resistance and some what smaller contact patch on the road. If you can live with the ride quality and the middle of the tire is not wearing out, then you are set. I would just make sure to check the pressure right after you driven on very hot day to make the pressure has not increased too high. I tend to check my tires after a hot trip for "hot" pressure and then the next morning for "cold" pressure, so I know where to set the pressure when they are cold in order to not exceed the max pressure when they get hot.Prometheus said:the fronts are always going to look lower as most of the weight is up front, as far as, do i raise the tire pressure in my tires higher than the manufacturer's recommended numbers. ALWAYS!!! and i've NEVER had a problem and gas mileage numbers have always been better, as well as tire wear. with the cost of tires nowadays, i watch the wear and alignment on a regular basis. increasing tire pressure between the car manufacturer's and the tire manufacturer's recommended pressure has been a practice of mine for many years with excellent results as well as tires that last much longer. you just gotta find the gray area, hehe
low tire pressures = higher friction = more heat = tires that: :explode:
Obviously there are many "schools" of thought here relating to proper tire pressure. There are some good posts re: this matter in this forum posted earlier in the year if you take the time to search. Also there is some good info. re: tire care at www.tirerack.com as one example. Just be careful setting your pressure too high based on the sidewall of the tire. Those ratings are from the tire manufacturer for the compatibility of being used by different vehicles which should fall in the ratings set from the individual vehicle manufacturers. The differences in psi on a cold tire vs. one after running can increase dramatically resulting in reaching very close if not exceeding the tire manufacturers recommended max.psi. When you read these articles all that I have read recommend setting to manufacturers recommendations due to axle weights and ratios, etc. Even running w/a full payload and towing all plays a part thus the manufacturer sets the ratings after taking all this in to consideration. Anyway just my $.021BadTitan said:What tire pressure do you run with??? Which tires do you have???
i have the BFG's and am running 42psi in each. The tires look a little flat otherwise. they aren't overinflated so there isnt any abnormal wear.
42PSI here, No noticable tire wear or anything. Ride quality is great. Imagine I'll keep it at that. I was kinda freaked out when I looked on the side wall because I have never ran 18" tires. Only 16" tires until now. Seen 44 PSI, HOLY CRAP!!Prometheus said:wow! you guys run your tires low... i've got the 18" Goodyears running at a healthy 42lbs. tire wear is perfect, ride is smooth, and the gas mileage is much better at 42lbs. vs running it in the mid 30s. And i am an absolute stickler for tire wear. running tire pressure that low is going to increase wear and lower fuel efficiency due to higher friction ratio, plus it is worse having low tire pressure when it is raining. oh well, run em at whatever floats your boat.

Your valve stems have radio transmitters on the other end of them . A tsb I saw said to have the tire poeple loosen the nut on the valve stem before breaking the bead on the tires to prevent breaking the transmitters.titan5.6 said:Ok, I have a stupid question. How in the hell does the air pressure sensor work? Will I have to disconnect something when rotating my tires or what? This one has bugged me since I bought my Titan
Did the dealer have a logical explanation for his failure to correctly set the tire pressure prior to delivery? I am pretty sure they have this on the check list. Mine came the same way. I am just grateful they weren't Firestones.Slick50 said:The dealer told me the factory loads the tires up since they rachet the trucks down onto the transport truck, and the higher pressure helps prevent flat spots on the tires. Anyway, sounds logical.
The max pressure listed on a tire's sidewall is a cold pressure, not a hot pressure.talltom said:Ok, tooI would just make sure to check the pressure right after you driven on very hot day to make the pressure has not increased too high.

Ok, ? I look at it as a MAX pressure at which it is safe to run the tires and if your tires cold are already at max pressure aren't you are going to be in trouble once the tire warms up? Or are you saying that the tire maker is allowing for a pressure increase when they they get hot? How much?Austin said:The max pressure listed on a tire's sidewall is a cold pressure, not a hot pressure.
