The search is down, as you all know, so I do apologize for asking a question that has no doubt been asked a hundred different times.

What tire pressures are you running in the stock Goodyears? Not application specific like racing, just everyday pressures?

Thanks
Chris

 

i run 32 psi in mine.. front and rear.

 

32 PSI. Front and rear. Bob.

 

Isn't the recommended tire pressure on a label on one of the door frames? Seems to me I recall seeing it there.

 

Speedin Bob runs 65 front and rear in his..........what's up with that?????


(Must be a "twisty" thing )

 

I've only been messing w/ the tire pressure since Dec, 'bout every 2 weeks. It doesn't help that temps are fluctuating...

Anyhoo, for the unloaded bed, I've found that 30# is ok, 28 is better for traction in take offs... Right now, I'm at 32# rear, take off traction is definitely not as good, but it seems about right for handling so far. I'll take it to 33 or 34 in a couple weeks to see..

Up front, I've run 34, and now 36#. That seemed better around curves, and it's not hurting my mileage etc...

I used to run 38 in my Cobra fronts, 1# higher than when I saw minimal 'roll over' on road course days... I'll probably work the fronts on the Lightning up more in the coming weeks as well...
Remember, the weight distribution of the Lightning is not the best, and, in inclement weather, you're better with as narrow a tire profile as you can get away with. The lightning having Flintstone-esque tires means upping the tire pressure to maximize foul weather traction...

Once I find a combo that's good all around, I'll post. Right now, I'm thinking that 32 is just OK for take offs but still good for handling out back. Up front, I'm guessing 38 - 39# will be good on the street. (hey! you never know when you'll have to merge from an exit on to a high speed freeway !)

 

I know the recommend pressure is in the door frame but I just wanted to see if anybody else found something better to run them at.

Thanks

I've run 32/32 with my lightning since I bought it.. I notice the rear tires tend to wear in the middle at that pressure, and no I'm not doing any burnouts or anything that would cause it other than driving long distances.... Dropping the pressure to around 30lbs seems to help even it out.

 

34/34 for everyday driving gets me a little better gas mileage, but rides a little rougher. It also makes the truck more 'tossable' if there is such a thing for a 4800lb brick. Dropping the rears to 32 or even 30 makes the rear plant better on the straights, but causes some instability exiting corners. I've ran them all the way down to 28/28; the truck rides better, but gets very sloppy, and unstable under braking.
