Toyota Tundra Forum

If you go with E tires and don't inflate them higher than a P tire, you can still get benefit if you are hauling a heavy load. If you run empty, that is different

The Tundra recommended air pressure for the stock P tires is 31 in the front and 33 in the rear, if I am remembering correctly, however the tires themselves are rated for a maximum air pressure of 44 psi. I pumped them up to 44 psi all the way around and the TPMS light has not come on. I have driven it this way for about 45 minutes.

I've gotten a pm from another forum member that says he has pumped up BFG E rated tire to 50 psi with no problem after resetting the TPMS switch on the dash.

So far, it looks like I should have no problem with an E rated tire on this truck with the stock wheels and tpms up to 50 psi.

2on... seems like you need to possibly call a tire/ tpms/ or even the toyota manufacturers.. they have divisions/ people who design - research this exact
question this would probably be the only way you could get an answer you
will feel comfortable with ...btw did you consider the dualing out suggestion? j/k

You could put the sensors in bands (like Ford sensors) and then run the regular high pressure valves in the wheels. Then you know the valves will hold the pressure. The sensor MIGHT still fail, but it won't stop you from cruising down the road.

What is "dualing out"? And, is a 285x65x18 the maximun tire size I should use with stock aluminum wheels with no lift?

Yes.

I've also heard "dualing it out" as referring to converting to dual exhaust, lol!

Got my BFG AT KO, 285x65x18, installed Saturday and so far, at 45 psi, everything is working great.

I trimmed the skid plate a few inches on each side, to be on the safe side, just because there was only about a 1/4" or less, clearance between the tire and the skid plate. The tires weren't touching but were extremely close.

I'll be getting a Line-X spray in liner this afternoon, floor mats and probably some step bars because this truck is pretty high off the ground.

The new tires are about 1 1/2" taller and 1/2" wider than the stock Rugged Trail BFG's.

I drove the truck 300 miles Saturday and the new tires make the odometer 2.4% off meaning it is showing 2.4% less miles than the actual miles are. I gives a false reading when checking MPG and I figure I will need to add (.4) MPG at each tank full to get an accurate measure of my MPG.

With the new tires on my 2010 Double Cab 4x4 automatic with trailering package and 430 rear end gears, driving on the freeway 65-75 MPH with no load, a/c on, tires inflated to 45 psi adjusting for the 2.4% odometer error, I got 16.4 MPG. I checked my odometer with my GPS before and after the new tires so this is my best guess on how to figure MPG with the new set up.

On this same section of freeway the best MPG I ever got was in a brand new 2003 Chevy Duramax 2500HD 4x4 automatic. With that setup I got 18.5 MPG but never got that high of MPG ever again.

Congrats on the new tires 2on2off! Let's see some pics!!
