I have 295 trail grapplers on my truck. The tire shop recommended 40 psi but that looks low... The tire states 80 psi, I know that's way to much for sure. What psi are you running in your Trails for everyday street conditions?

I too am running the Trail Grapplers at the shops recommended 40psi. They def look under inflated, quite a bit of sidewall sag.

I've had the same 295's on my truck for 14k miles now, always run at 40 PSI and they're doing fine. No uneven wear or anything. I'm thinking I'll get 30k or slightly over until I need new tires

I run between 45 and 50 on mine. Got 34k on them right now and will get much more

Good to know. Im going to run 50 psi and try that for a bit.

I run 50psi in my Terra Grapplers and have had no problems. I'm sure if you run that in Trail Grapplers they'll be fine.

I run 45 psi on my 305/55/20's

Here is a picture of a quarter in my tread with 34k miles.

That looks way good for that amount of miles. I hope to get at least that from mine. How often do you rotate?

I dont have the trail grapplers but I have the Terra grapplers and I keep them at 50 psi. I have about 30,000 on them and can see me getting at least 50,000 out of them. I rotate every 5k miles when I change my oil since its free with an oil change
