Just curious, I'm toying around with it right now. Used to run 33-35 but the max PSI on my Terras (P rated) is 35 so I figured since I'm not at the weight capacity I should back it down to 30. 245/70/17.

I want to do the chalk test but I don't think there will be dry or dry tires till the 4th of July at this rate. Damn rain.

Is 30 in the zone? Or does anyone recommend something different?

For all the tires I've ran..................

KJ at stock weight to 5500lbs............

225/75R16(E) and 265/75R16(D) MT/R's(old style) - 38-40psi

265/75R16 Trxus MT's(D) - 38-40psi

KJ at 6200lbs+.............

315/75R16 Destination MT's(E) - 35psi

35x12.50x15 MT/R K's(C) - 27psi,which have a max psi rating of 35psi also.


Really depends on rim width but if your on stock rims 30-32psi should be okay and wear good.

Thanks, was hoping you'd chime in. Might up them to 32 next time I check them, might get a bit better MPG.

32psi on the stock rims with 245/70/16 on my 02. Looks like the TPMS tells me I'm around 34 all around on the 235/65/17 on the 05.

Bout 35 on my load range D's. I upped the rears to 40 when I had a full cargo area, towing my waverunner, and bike rack. Drove about 900 miles like that.
