Hankook Dyna Pro ATM 265/75/16, Tire Pressure??
 
What are you guys running for mostly highway driving?
And do I need to have the TPMS set if I change the pressure from say 30-35lbs?

Discount set them at 29f, 29R

Thanks, Ryan

Hy Ryan, I am running mine at 38 psi front and back.

They are a 44 psi max. tire and the Rugged Trails that came with the truck were only a 35 psi max. tire (with a recommended run pressure of 29 front, 32 rear).

The Dynapros are a superior tire to the BFGs, and with a stronger make/ heavier rating need a bit more air than the BFGs did.

They will feel 'squishy' at 29-32 psi... 38-42 they feel good. You can do the chalk test to see the ideal pressure, if you want. But, at 38 psi, mine are driving and wearing great.

Thanks for the info, If I air them up will the TPMS sensor light come on and need to be reset?

Thanks!

Yes... it is easy... in your owners manuel is the instructions.

Gotcha, I guess I should probably read it sometime! :D

I run my P-series dynapros at 38 PSI front, 35-36 PSI back. DCSB 4x4.

Just a curiosity question: Why 2-3 psi less in back? With Rugged Trails, Toyota recommends 3 psi more in back... Just for simplicity I run my backs the same as the fronts (38 psi). Thanks.

I base it off of sidewall flex. I like a nice flat patch of contact with just a little flex but not much. In my truck, the flex (bulge) in the front is noticeably more than in the back at any given pressure. Cranking up the PSI in the front a bit evens it out. I figure I'll get more even wear if contact patches and sidewall characteristics are as close as possible.

Interesting.:cool: I run mine at 32 PSI front and back. Maybe i'll change it up. BTW, do you have any problems w/ the lugs chunking? Might just be the desert wheeling.

Mine are P Series and I set to 38F, 38R, Will see how it rides...
DCSB 4x4

I have 10,000 miles on my Dynapros, and they still look pretty new... no failures, flats or 'chunking'.

Maybe because your pressure is too low for those tires?

The Rugged Trails are 35 psi max tires and I ran them at 32 (the rear recommended amount by Toyota). But, the Dynapros are 44 psi max tires.

Killed this little guy trying to pump 38psi. Lol.

They came out of the wheel shop set to 30 all around. Mine are p-series, and they showed way too much sidewall flex. I would expect very short lifespan if I had left them there. They looked half flat.

Remember, these ARE p-series but they're also more sturdy than a standard car tire. While most p-series tires have a max PSI of around 36. P-series dynapros have a max PSI of 44 if I remember correctly.

I have no experience with the LT-series tires.

ETA: No chunking but only about 6K miles on the tires and I run 95% highway.

Look just a couple posts up... 44 psi is the max... and for my DC 4WD, 38 PSI works very well.

Been running 38f and 35r all week. Truck feels great. Reps when I get on my PC.
