    I have installed the Coker 6.00X16 on my truck (54). Any idea what the proper tire pressure should be? They are radial tires.

    The tires will have a max inflation rating on them. Assuming they are max 32 psi, i would put 28-30 psi in all of them and see how they look. Then you can adjust them accordingly. Remember radials have that "Damn I need more air" look.

    Just keep in mind that under inflation will wear the tire and so will over inflation. I run anywhere from 30-35 psi in all of my tires. Also the more air the harder the ride.

    Thanks!

    I have 30 in front and 32 in rear; and you're exactly right, they look under inflated!!
    thanks

    less in the rear

    My son wore out his rear tires in just a few months with too much air (30 in front, 30 in back) on the second set he listened to ol dad. For his 84 chevy we finally figured out the key,,, 28 front 18 back. He carries no weight and now his tires wear the same (as long as he keeps his feetsies out a da metal). He runs 50's on the back, 60 front. So it depends on weight, width, size of foot and speed. Just gotta pley wid it. But probly less in the rear is better.

    Now have I got everybody confused or what?

    Overinflation Wear Patterns

    So then, the tread wore out only in the middle did it ? .

    One way is to use chalk or crayon across the tread and go drive it , make a corner how you usually do and se who the mark scrubs off ~ this is how we dial in the tires on the race car .

    18 # is _way_ too low for a radial tire and -will- cause undue sidewall flexing leading to early tire failure vie tred ply seperation....

    That's what causes all those treads you see lying along the side of the road to come off under inflation , never over inflation .

    These trucks are heavy beasts and so need ome decent air pressure in them .

    Put-Put , why not post up the _entire_ size info off the tire's sidewall so we can help figure ut what you need to do , if these are car tires rather than truck tires , it'll make a differance .

    6.00X16 is a Bias Ply tire , radial should have different sizing .

    Checked with Coker

    The tires are radial, but look original. I contacted Coker and they recommend running 41 psi in the front and back.

    That's a lot of pressure but I'm sure they know what they're talking about. If they start to wear more on the middle of the tire then just let a little pressure out and it should correct that.

    tires

    Can anyone say FIRESTONE??
    Seriously, Nate is correct, 18 psi is way too low for a radial tire!!!! The Firestone tires were not the problem, it was the people who did not check the air pressure, ran them low, and then overloaded them, causing sudden failure at high speeds, on a vehicle that failed federal rollover standards. Fords solution to the fact they failed the rollover standard was to lower the air pressure, which lowered the center of gravity just a hair, allowing them to squeek by, and pass. Notice now how the new Exploders have rollover protection, for your safety (read, we don't want to be sued any more). Reinforced truck tires will run some pretty high pressures. Always check manufacture specs, and remember if you run heavy loads, you may need to bump up the pressure to compensate. Be safe!!!....Mike

    Tire Pressures

    Yeah , if they're LT tires 41# may be a bit too low ~ look at the sidewalls as the Max. pressure will be there in raised print , pressure you should run will be pretty close to that as these old nails are heavy suckers .

    As far as Exploders rolling over , I still want to know why the blowouts happened on the left rear tire ? that's not the drive tire , the right side is .

    Dealers were told to lower the tire pressure to 25# ~ that's criminal in itself in my view .

    Low pressure tires have too much sidewall flex and this heats up the tire , hot tires delaminate and blow out...

    I'm old enough to remember the Fords in the early 1970's having the exact same problems on the passenger cars ~ tires blowing out in 3,000 miles or so , guess what brand they were ? Firestone ! .

    You'll never find a set of those craps on my rigs .
