TV Tires

Stormrider151 · 03-27-2015, 08:01 PM

I'm about to put E rated LT's on my truck. Everyone seems to agree that this is one of the best ways to improve towing. I'm looking at the Mastercraft Courser tire that my tire dealer suggested. I've been buying my tires from him for 30 years and he's never steered me wrong. I have a couple of questions for those of you who have changed to the E rated tires.

1. How does the heavier tire affect ride and non-towing handling?
2. How do these tires affect the factory TPMS?

I'm not changing the size of the tire just the load rating. Thanks a bunch.

What air pressure were you running and what PSI do you plan on running?

Stormrider151 · 03-27-2015, 08:15 PM

In the "P"s I have now 38psi. I don't know what the optimal pressure in the E's would be. I do know 80 PSI is their max pressure.

I run them at 80 PSI all of the time so when not towing the PU ride is stiff but I deal with it.

Some here disagree with this but that's fine by me as I have one boss now and even she does not hold sway when it comes to the XL.

I just put Cooper Discovery AT3 E tires on my tv .I am running 45 psi right now and to be honest I can't tell the difference from the P tires at 35 psi maybe little stiffer but not bothersome. I plan on running 65 psi when I tow .I to wanted better towing. (less sway and bounce).

And it has no affect on the trucks TPMS? Seems I read somewhere about tire changes like this messing it up. But then I have visions of living in a grass hut on an island in the tropics. Old age does that.

My F150 came with E rated tire because of the HD Payload Pkg. The door sticker says to run 55 front & 60 rear. When towing I have gone up to 65F & 70R.

Your right it has no effect, but....If he has TPMS that are calibrated to his "P" rated tires that he run's at 38psi, TPMS should alert him when pressure goes down by about 7psi. If he is running "E" rated tires the pressure will have to drop (from what ever he is running them at) to about 30-31psi before he will get any kind of alert on the dash.

Background on TPMS Relearn and Reset Procedures
Each vehicle equipped with TPMS has a set of instructions that must be followed to activate and confirm the TPMS communication. This is known as the TPMS relearn procedure. These steps are set out by the auto manufacturer and vary from vehicle to vehicle.
In some cases the TPMS system will automatically relearn this process without additional steps. These types of relearn are known as “auto-relearn”, and are typically accomplished by activating the sensors and driving the vehicle. Other types of TPMS relearns include OBD II, which involves connecting a special TPMS scan tool to the vehicle ECU and entering the sensor information directly into the vehicle.
Knowing what to do is critical to safely returning the vehicle to the customer.
These required steps may change when a different TPMS system has been installed into a vehicle, such as when a programmable sensor is used.
TPMS MANAGER has a database of relearn procedures for 95% of direct TPMS equipped vehicles. Learn more about how we intelligently deliver this information in the following video.

Thanks guy's. That's exactly what I was looking for.

The LT tires are also heavier and will have an adverse effect on your fuel mileage. IMO LR E is overkill on an F150. Consider LT LR C.

I understand where your coming from on fuel mileage and if I were driving a lot it would be a consideration. I don't drive that much and the truck barely has 25000 miles on it. I've had real issues towing my trailer and I'm trying to get the most stable safe tow I can out of my truck. Thanks for the reply it is appreciated.
