Air pressure recommended

I have 265/70/16 Duratrac 112S on a ‘17 dcsb 4x4 OR. What tire pressure is recommended? Driver door jam says 30 psi. Thoughts, feelings?

Took em for a cruise at 60mph on highway, and neighborhood 25mph. No vibration in truck. Next day on an different relatively smooth highway there was a bit of wobble/shake. Very minor but noticeable. Noticed I was going 50-55 mph when it occurred. Re torqued, all still at 83 ft/ lbs.

 

Thinking I should get em re balanced if it keeps up.

 

I run my Duratracs at 36 psi.

Average 25 mpg on highway at 70mph.
Overall I average 22.5 mpg, but I drive like a grandpa.

No lift, all stock.

No shake or vibration at that psi.

Good idea to rebalance.

Might want to check ur alignment as well.

 

Thanks,
What kind of wear/life are you getting at that psi?

 

I am hearing from most duratrac owners that they rotate always at 5000 miles or sooner.

 

Only had em for 13k miles, so can't comment on tire life just yet.

But they r wearing nicely and evenly.

Yes, rotated every 5k.

 

Google the term 'chalk test'.

It's a worthy exercise.

 

Will do. Thanks

 

Got lotsa chalk.....now to scout out some acceptable flat pavement void of tons of pot holes and crevasses.

 

Are these brand new tires for u? You could've thrown some wheel weights...

 

what does the manufacturer recommend?

as far as the wobble...check the balancing of the tires.

 

Those are E loads? I would run at least 35 psi.

 

Your new tire is the same load rating as the stock tire(euro metric 112SL).
30 psi

 

My 265/75/16 E load duratracs required a lot of weight to get balanced, even the tire guy was surprised. They had to stack a bunch of stick on weights and had to add the old school weights as well. They rode super smooth though.

Amazing tire in the snow and off-road, everything else, not so much IMO.

 

I have often noticed (with my stock tires) an initial vibration because of overnight flat spots. This goes away after driving for a few miles. Whenever I put on new tires I see my dealer for a road force balancing on all four.

 

Brand new, yes. Good point. Might have to get em checked.
