I have an 04 Dodge Ram 1500 4x4 short bed quad cab with automatic
transmission,5.7 hemi and 3.55 rear end. It has a cold air intake and a
transmission temp gauge added onto it. I am using E class tires with 33"
BFG all terrain T/A tires. I have a prodigy brake controller and load
leveling and sway control on the hitch. I am towing a Rockwood 8314ss camper
(2007). I have noticed that while I can tow it and stop it safely the temp
gauge runs around 195 F degrees. I towed it for the first time about 2 weeks
ago. It weights around 6,000 lbs.
I have heard that I can change gears(?) or something to increase the
towing and make it easier on the transmission and engine. I don't want to
cook the transmission although I don't know what the danger level is in
degrees. I do check my fluids before every tow both coming and going on
trips. A new truck is out of the question right now. And I don't want to
spend a fortune on something that will give little back. I have also heard
that changing gears will also really screw up the gas mileage which is
terrible anyways. Okay now I'll stand down and wait for the flogging to
33" tires are probably hurting your performance and mpg considerably.
Drop to 30-31" which is stock size for your truck. I have a Hemi
Durango 4x4 3.55 and pull about 5,000 lbs in very mountainous terrain.
It does have a factory tranny cooler as well as an auxiliary engine
cooler that works great.
If you upped the tire size then you need lower gears. Since you will be in
there may as well go lower than the equivalent stock gears. Mileage will
take a dump though. I am running 38" on my 1500 4x4 but I have replaced the
axles with 1 ton units off a diesel with 4.10 gears. Cant pull crap though.
I have a '96 1500 with a 5.9 (3.55) and an '04 3500 dually with the Cummins
(4.10). Junk the 33" rubber. They may look cool, but they will absolutely
trash your ball joints and steering arms. They wear poorly. The extended
sidewall makes the whole truck wobbly, ruining the handling. In addition,
your effective axle is now about 3.4, effectively making your already poor
towing much worse. I am not sure what your factory max towing weight is, but
I think if you haven't already exceeded the factory recommendation, you are
right at the limit. If you consider nothing else, please consider the
inadequate brakes that equip the 1500. If you want to tow, get a 3500 and
the Cummins. You won't believe the difference. On my 3500, I use 22.5
alcoas. The 1500 is a toy. The 3500 is the real deal.
I have the K&N cold air intake system. I am wondering what the thermostat
has to do with it? I changed my tires thinking that the bigger ones would
have stronger sidewalls. I admit that I liked the Michelin stock tires
better and the ride was smoother. Does one need to have E rated tires for
heavier towing or are the stock ones sufficient? Thanks for your reply. I
do agree that the cat back Gibson dual exhaust system is probably a waste of
money. Sounds good but there are days I wish I didn't have so much noise.
I guess that stock isn't always bad. Howard

the stock tires are matched to the truck's load rating. increasing the
load rating of the tires does not increase the truck's RAWR. (Rear Axle
Weight Rating) and thus doesn't do much to help you. ALTHOUGH E rated
tires will be more stable when your pushing the upper limits of C rated
tire's ratings. But there again your pushing the limits of what the truck
is designed to do in that case, if not already exceeding the design
The two are not directly related. The cold
air system is one of the few easy changes that has
been shown to increase low end torque. It's
relativly inexpensive, and pretty simple to
A colder thermostat will pulll more heat out
of the heads. That helps prevent detonation, and
you can use mid grade instead of premium. It also
gives you a little more lee-way on hot days with
long grades. BUT, only do that if you've
re-programmed the computer to accomadate it.
Otherwise, you could make the engine run bad, and
cut your mileage by a bunch.
