i keep mine between 42-44....like dak_in_black said, dodge didnt make the tire...i follow the tire manufacturer

 

Billcat how the heck do you get 18mpg in city driving. I'm lucky to get 13mpg. I have airaid intake, electric fan, and gibson exhaust on my 05 4x4. Do you use premium gas?

 

If your truck is manual, you can get 17 mpg or so around town, totally stock, if you shift around 2000 RPMs. For an auto, just drive easy, pull away from stop signs and lights slowly, and you'll see 16, at least.

 

That's all fine and well but just remember that's a max inflation number. A warning not to exceed 44psi or risk tire damage. Its unrelated to any other issue and its not meant to be taken as an ideal pressure to run, especially for all situations. Anyway the max inflation value printed on the tires is not the manufacturer's recommended'best' pressure. Tire manufactures can help you determine good pressures to run, but it varies from vehicle to vehicle, weight being the biggest issue but also body roll and stuff. For this reason most tire manufactures will just refer you to your owners manual. That's not to say that there isn't legit reasons for going higher or lower. Mileage, load, tirewear and weather conditions are all factors.

Regardingmotorcycle tires, I run 8psi higher in the front and 6psi higher in the rearon the track than on the freeway.
The Michelan rep has helped me arrive at these numbers after trial an error on different tracks. My track tires don't even have pressures on them. Heck I don't even think the Pilot Powers I run on the streethave a max inflation rating either. Its been a long time since I've run Dunlops but I'm not sure the D208s had max inflation vals either.

Hope I'm not being a jerk or anything just want ppl to be cafeul before they just go out blowin their stuff up to what they see on the tire.

 

In my dreams I might see that kind of mileage. I drive as easy as I can and am lucky to see 13mpg. I have auto trans.

 

Too late [sm=happybounce.gif]


You make some valid points. Speaking only for myself, I have found that I get better results toward the higher inflation number. Wear patterns have remained normal, mileage has increased, and the ride is a little stiffer; and this has been true for every vehicle I have had. But I agree that with each application you should re-evaluate your tire pressure.

I currently run Avons on my Valkyrie and as I said before, it is a large and heavy bike. If I run anything less than max psi on the tires (42 front 40 back) it wants to wallow and plow through turns.

I never take anything too seriously that I read on any board. This home brew "power wire" may be a great thing, will I do it? Maybe after I do some research and see what other people think of it...

 

Wow. That's surprising...some of the other auto guys have had pretty good success driving easy and getting higher MPGs. Do you have the HO?

 

I try to pull away from lights easy...but yeah...ever since i got my BFG tires and before my tuneup, I was getting like 13mpg...of course, here in LA you have to stop every 3/4 mile or so, and traffic is stop and go constantly...

 

Yeah, traffic makes a really big difference too. I'm in a smaller town near Amish Country...there's not near as much stop and go around here.

 

I have the 4.7 auto. When i first brought it i averaged 16 in city and 19 on interstate. i put the filter and muffler on and drive the speed limit and hardly ever get on it. Hell now that i read all the post around here i guess i am lucky. work is anywhere between 30-45 miles away and i use regular gas (the cheapest). pretty much i am a tight wad!!
