10 PLY tire recommended PSI

Well... yeah

 

I tried different psi 72 the truck bounces nervous . 65 still squirmy . 55 gas mileage sucks .. 60 is the magic psi

 

Yep, my door sticker with BFGs says 46. Dealer screwd it up at every rotation even when I told them. I was running 50 but not sure what Discount put in last rotation. TPMS light has not come on so I think they are good. 10 plies handle 50 differently than lighter tires.

 

35 Psi on my 10 ply ProComp AT's. As was said, the ride starts to suffer above that.

 

18 on the trails

40 front / 42-44 rear (depending on extra weight)

My chalk test looked good to me. When in doubt, chalk test.

Edit: old ass thread lol

 

What tire are you running? And do you know how much the pressure is changing at highway speeds? And perhaps temperature?

 

10 ply BFGs KO2s on 17" were OEM on the Rock Warrior; sticker says 46 psi if I recall. I've been running 45-50, mostly towing. 4-season performance is excellent; wear is excellent.

On the third KO2 set now, replacing at 50K intervals. They could definitely go longer, but I need deep tread for the often unplowed winter conditions and the mudpocalypse spring thaw at the homestead.

I look at the tiny sidewalls on the mall crawler slicks on some of these trucks and shake my head. If there's one thing you can do to ruin and hobble a truck, and turn it into a Prius with a large cargo area, that is it.

 

Hercules Terra Trac A/T2 - 275 65 18 - 10 ply Load E , Hercules said to run a minimum of 48 psi on the tundra with these tires , I run 53 psi unloaded and while towing , nice even tire wear so far !

 

Just joined. 2019 TRD Pro. Trying to figure out the tire issue.

I learned a lot when I spoke to a level 2 BFG or Toyo tire support person on the phone a few years ago.

A load E tire is a standard rating each tire has to abide by, per Feds. Brand irrelevant. As I am sure many are aware of. At the time, I never really pondered that, that much. Makes sense though.

That being said, I had a dually, that road like crap unloaded. I found an inflation chart, went from 80 down to 35, in 5 PSI increments with corresponding weight capacity for each 5 psi step. I hand calculated the chart down to 15 PSI. Took the front and rear axle weight of my truck. Added up the passenger compliment and fuel etc... for additional weight. End story, loaded with peeps, fuel, and a 100 lbs in bed for any groceries, traveling, etc... I ended up running 20 PSI in the rear, and 62 in the front. The ride was great compared to when the rear was inflated to more normal pressures. Tires wore normally, no issues. Did not act goofy, etc... Ran up and down I 70, usually in the left lane, not the least bit worried about not enough tire pressure. Handled better actually. Door sticker said 80 was required in the rear... With 80 in, those little seams, etc on concrete roads, etc around turns felt like might just bounce out of line around a turn. And on snow, it was a polar opposite in traction with 20 in the rear.

This was with 3 different sets of tires. Two OEM size, one set slightly larger.

I am not sure if I am going to go with a LT tire or non LT, like the OEM tire. LT is tougher, etc... Also, seems to be a lot of stiffness for a crappy ride. Unless running down into the 25 to 35 range. I am currently guessing, have not ran numbers. I know many of you like the 10 ply toughness for off roading. I don't see myself going off roading to such an extreme, like I used to with my full size GMC Jimmy, aka old beater.

What is the front and rear axle curb weight, not the gross max weight? Just empty unloaded. I can't seem to find it yet.

 

I contacted Falken about tire pressures on my Rubitrek 275/70/18 and they said 43 for the rear pressure and 40 for the fronts.

 

Old thread. Just got 285/65/18 Toyo ATIIIs. Toyo recommended 40/43 front/rear. I’ll try that and chalk it. Tire place had them at 35.
