Going by what Tire Rack list for OE tires for your 2006 1500 Mega Cab 2 or 4 wheel drive is a 265/70-17 load range E tire, I would say someone cheep out on new tires before you got the truck. JMO

Look at your VIN sticker, it will list the stock tire size that is the MINIMUM to get the rated GVWR, anything smaller would de-rate the GVWR.

Note that the front GAWR (5200 lbs.) added to the rear GAWR (6084 lbs.) does NOT add up (11,284 lbs.) to the rated truck GVWR (8800 lbs)!

OP, please advise what type, size, and load range tire is specified on the door jamb tire/load placard.
Personally, I would put the next size larger LT tire on, in at least Load Range D or E.
That's what I have on my Dodge 1500, and they work great.

There are a min of three different sub-classes in the half ton class

Most 'half ton' comes with 'P' class tires. The +6K GVWR and +7K GVWR

The fake half ton comes with 'LT' class tires. The +8K GVWR and some 'off road'
packages. 'P' class tires normally do NOT last long in serious off roading

While you're at it, recommend a steering stabilizer.

X1000 percent...illegal and a danger to you and everyone around you

In Europe/Japan/etc...if they caught you with those on that TV...they'd
ticket and boot you spot on

Then find the dealer who installed them and fine them. To even revoke
their business license. If injury from that vehicle (even if not 'cuz
of the tires)....jail time for the owner of that shop which installed'm

The door label from the OEM for that vehicle has the

M I N I M U M

tire class and size

Since it says 70PSI, it must be in the 'LT' class tire. With the tires
sidewall listing of 44PSI...it is a lower class tire...AKA 'P' class
Which needs to be DE-RATED a min of 9% of it's sidewall ratings
when used on a pickup

Forget about freebie advice on these types of forums. Go by the facts
and that is your vehicle's door label. That tires class and size is
the MINIMUM tire

Plus...all things designed/engineered are NOT for the good days out
there when a riding lawn mower 'can do it', but for the worst day
out there when Mr Murphy crosses your path.

Either you have the proper sized everything, or not. No time to go back
to the store for bigger/better...nor re-setup/adjust

(edit)...PS...the PO might have also changed out the wheels and to
be safe, check their ratings. There are like ratings for wheels and
the kind of person who did that...might have gone to 'P' class wheels too

Hello all,
I was wondering if anyone can help me with a tire pressure question. I have a 2006 dodge mega cab 1500, 5.9 hemi. I have a 26 foot starcraft ar-one wide body weighing about 5000 lbs. My tires say max tire pressure is 44 psi. My door panel says max load pressure is 70 psi. Normally I know to never exceed max tire pressure on a tire. Is there something different about towing that allows you to go above a tires max psi? When I put 44psi in all my tires they still look a little low. And when I put the trailer on the hitch it looks really low. Is it bad to put over the max tires psi when towing? Any anwers are appreciated. Thanks.

WARNING!!!

You need to replace those tires IMMEDIATELY. You've got the wrong kind of tires and they are going to fail due to overloading.

DON"T WAIT!! DO IT NOW!!

Go to a tire dealer and have them look at the situation.

Yeah the 1500 Mega Cab comes with a 8510 GVWR and 6000 RAWR 8 lug wheels and Load range E tires.

Now if the OP< meant he has a 1500 quad cab then it comes OEM with P tires.

And I guess its possible Dodge/someone installed the wrong tire or tire placard.

Anyhow he's towing a very light weight trailer so I would use the 44 psi max sidewall tire pressure in the truck.
It was common some years ago, when 3/4 ton trucks road like a log wagon, for 3/4 ton truck owners to go with a P tire with their light weight loads.

A bit of Chicken-Little here IMO. I just finished a 4700 mile 3-week cruise from eastern Iowa to northern California with both interstates and VERY twisty mountain roads and 8% grades. My '08 Tundra with "dangerous" P-rated tires @ 40 lbs. handled it all confidently and comfortably towing my 7,000 loaded Outback 25 footer.

syndrome85...as others have noted, the original tire size/design/rating is different than what you have on it now. Use the existing pressure on the tire.

You are comparing a Toyota Tundra which is a light-duty "1/2 ton" pickup truck that weighs around 5500lbs off the lot to a Dodge MegaCab 1500 which is actually a 3/4 ton truck and weighs almost 8000lbs off the lot.

Apples and oranges.

The Dodge comes with LT Load Range E tires from the factory. Your Tunrdra came with P-rated.

Someone cheaped out on the tires on the Dodge.
