i have stock tires on my 2012 crewmax 5.7 sr5 trd model..should i keep the tire pressure where its at while i tow and not tow or should i raise the pressure when towing..thks

What are you towing?

2014 attitude 27 cbg loaded about 9000-9500k

That should put your TW at around 900-1500#, increasing the load on the rear by about the same amount. What tires came on your truck so I can find an inflation table for you?

 

[Ditchhooker]

I usually do for the extra stability, max (44 psi) on the rear and usually 38 on the front. I used to run max on the front as well, but I have scaled my rig a few times and found I don't need max psi on the front now that my hitch is properly set up.

If you have the Bridgestones, I found them to be really squishy even at max psi on all 4 when towing. was really glad to be rid of them.

^if that is all the higher that the stock tires can handle, then max them out. If you tow often enough, you will be much happier replacing the tires.

truck came with bf goodrich rugged trail ta

If the max pressure on the sidewall is 44psi like it is posted above then I would run 44psi. If you tow a lot you would sure benefit from some better tires, that is a lot of weight.

cool thks..ill raise the tire pressure when towing

 

[brockeverly]

Just looked up the inflation tables for that tire and at 44psi they can handle 2365#. Given that info and the fact that you are likely over payload (1645# payload, 10/15% of your trailer weight alone makes up 900-1500# of that), I would have new E rated tires somewhere rather high on my list. They will make a world of difference with the load behind you.

When I had the stock BFG tires, I did like Ditch said, I aired them up to max 44psi at the rear and 38psi up front. I replaced the tires this past week with the Michelin LTX M/S2 LT275/65/18 tires, they are load range E, I'll be airing them at 50psi rear and 40psi front when towing, we'll see how that goes. So far these Michelin's are a night and day difference from the stock BFG's. The Michelin's ride so much nicer unloaded and not stiff at all. I'm running them at 39psi rear and 36psi front unloaded. Like mentioned above, you may want to replace them stock tires for some D or E rated tires if you're going to tow that heavy.

My tundra came with the BFG rugged terrains and I am hauling two dirt bikes and a generator in my bed and towing a 5600 camper this weekend. From reading these post I should air my tires to max psi correct? If I remember correctly they are 44 psi as well.

Thanks guys

The proper way to air up your tires when towing is to put the truck under the load and then inflate the tires until the sidewall is the same height that it was unloaded, not to exceed the max psi rating of the tire, anything other than that is just guess work.
