Hi guys, wondering if you could help me out.
I have a stock 13 Crew that had OEM P265/70/R17 Goodyear Wrangler SR-A's on it.
Had a bit of cold temps and black ice just before Halloween that convinced me to search out other options, as I was looking at a set of snow tires as well.
Long story short, I decided on General Tire Grabber AT2's, but I went with the LT265/70/R17's.
The main reason I moved over to the LT tire is that it has the snowflake symbol which it means it's rated for severe snow conditions and in Ontario that is considered a snow tire. My insurance rate drops quite a bit if I have "snow tires" on in the winter.
By going to the LT's, I have essentially a "all-weather" tire, as opposed to an all season. I know, I know, they're an "all-terrain".....
My question is:
The placard on the door says the pressure should be 40 psi, but that is for the P rated tires.
I know that the cold psi can be up to 80 on the LT's, so I'm wondering if by staying at 40, am I running the tires a little soft? I'm worried about prematurely wrecking the sidewall by running soft and heating up all the time. Not interested in a blowout!
The tire shop I bought them at said I should keep them according to the placard, but there is no suggested tire pressure for the LT's on the door.
I checked my owners manual, both the one in print, and the CD that came with it. Nothing. Zero. Nada. Zilch.
I assume that going from a P to a LT is a fairly common thing, so I'm wondering why so little info?
Any feedback that you can give would be greatly appreciated!
* I know the LT's having one lower speed limit than the OEM's, but here in Ontario I am never going to be able to travel at the unsafe speed long enough to do any damage to the vehicle, only my pocketbook from the cops impounding it! If you get caught here going more than 50kms over the limit, your truck is impounded and they suspend your license for 7 days!*
