What is the best tire pressure for 265 70R17?
If they’re lt (10 ply) rated, you’ll want around 43-45psi. Running lt (load range 122-128ish) under 43ish psi on the highway is a really good way to have a tire delaminate and destroy your fenders/abs system/brake lines, and can often cause a roll over. Choosing the right tyre pressure for on-road driving for everyday bitumen driving, most 4wds should run between 30 and 36 psi when the tyres are cold. Here’s a rough guide: light load (just a driver and a light pack): 32-34 psi. Heavy load (extra passengers, gear, roof racks): 36-40 psi.
