i have a psi question and didn't wanna start a new thread. they were at 37/38psi and it looked like the tread was too thin (or the tire was over inflated) i lowered them to 35psi and at higher speeds it's all over the road. a guy at work w/ 35s was saying he's running at 50 or 60psi and i should raise mine back up to maybe 40psi.

what are you guys who are running 265/75-r16s running at?

 

lead weights > zinc weights

Also clip weights > tape weights.

I was using tape weights for a while and my tires would lose balance after a couple months, I was balancing them all the time. I used to be a big fan of the tape weights but it got annoying. I work at a tire shop so it wasnt a huge inconvince to get the truck in to do a balance, it was just annoying that I was doing it so often.

 

285/75x16, running 28 - 30 psi…

 

I run my 31s at 30PSI in the winter and 35PSI in the summer.

 

ok, so why is it so squirrely at higher speeds? isn't there a post or two on here about re-balancing after a short distance?

 

Yeah Pedro said he re-balances after 100 miles

 

More sidewall to flex.

 

ok, they must have been over filled and i read the gauge wrong. i triple and quadruple checked and the gauge always said 50. i started letting air out until the gauge consecutively read 38. i took it for a jaunt around a couple turns that i would take at a slightly higher speed and on the expressway and the squirrleyness went away. i'll try this psi for a bit and see if i notice any issues. i also should have mentioned that the load is an "E" rating and the psi on the side of the tire says 60 cold.

 

E? Wow when did you get a F250?

 

that's what they gave me.

 

looks great man. I run between 33-35 psi but I also have standard load tires.

 

stupidity is toxic. lol just playing but you should be on a load range C tire if i'm not mistaken. the tires will handle/ride like *** if theyre way off correct load range. i've read about this from numerous other people with duratracs and the general consensus was that its pretty imperative that you get the right load tire with duratracs or they track like **** on the highway and just drive poorly in general.

thats just what i've read about them though so idk. go back to where you got them and ask wtf they gave you a tire rated that high and not duratracs in a C or D at most.

 

ya they should have gave you load C. But they probably didnt have any in stock or just didnt care.

 

Thats horse sh*t. Take them back.

You should be at load range C. F150s are usually at D and F250/350s are E.

E is absolutely ridiculous for a compact truck unless you're running 35s.

I would raise some hell.

Exactly. The E load range explains all the issues you have been having. They will cause rough ride, wondering (because the tires doesn't have enough weight from the vehicle on them to cause sidewall flex for grip). The PSI is to high because they are designed for a larger vehicle and that is causing issues as well.

If you don't switch you are going to hate them.

 

like mentioned. i lowered the psi. they ride better now. i like them more now then when i got them. if i kept the E ones would that increase my tread life since "less weight" in on them or would they wear different since there is less air (38psi) and uneven tread surface/larger footprint then at 50-60psi.

 

logic says they would wear faster because they are underflated.

but i'm no tire tech.

 

neither am i. that's why i asked.. also the tire place i got them is in detroit and i don't want to make a special trip if i don't have to. if the side effects are not as drastic, i'll keep these but if they cut the tread life in half, i'll ask the dealer to make right.

 

special trip across the river? haha you can probably see detroit from your house.

 

Yeah hopefully a more tire oriented person will chime in. IMO customer satisfaction and making a point is worth my time

 

moris how much lift did you get fromn the pre keys in front??? i want 285 but worried aboyt rub

 

i can't see it from my apartment but with work depending on what i am doing, i can cross up to 35 times a week. mind you that is a high seniority run with sat/sun off. i took a run last year that had me sun/fri off. so yea that was me crossing 30-35 times a week. now, this run has me crossing up to 14 times. i do a tunnel run on sat and sun nights.

as for lift, i got a couple of inches. i rub on my front sway bar at full lock. that passenger side flap also rubbed but i took it off. i also cranked them. i can't tell you how many turns since i measured each fender and made them level so there is very little ranger lean.

oh yea, the place is like 30 mins out once i cross. so it kind would be a "special trip"

 

pre keys wont do anything for ya. You already have them. I was worried about 285s and eneded up getting 265s but I have some saggy B bars that I couldnt crank anymore. If I coulda got another inch outta my bars I prolly woulda went with 285s. That being said, my 265s do rub on the sway bar and the inner fender at full lock. I coulda got away with 285s though.

Morris what was your measurements on the fender after you cranked your bars?

 

https://www.ranger-forums.com/snapshots-69/pre-key-aal-done-pics-inside-122698/

says in there. w/ the tires my measurements are like 35" front and like 36-37 for the rear.

 

hmm well i think my front is sagging some. My drivers side bar is maxed and with the 1 inch BL. Im sitting at like 36.5 front and 39.5 in the rear. Stupid B bars.

 

i've got double 1's for bars and double c's for springs since i ordered the towing package.

i do know this, i'm not replacing bars, i'll step up and do the coil swap.
