What is 07 T4R SR5 “Tire Lug Nut Ft Lbs Torque range” and “Tires PSI” range?

[jow]

What is 07 T4R SR5 “Tire Lug Nut Ft Lbs Torque range” and “Tires PSI” range? I am finding different values in my search and Owners Manual. I had my tires rotated and air pressure checked at Discount Tires. Their info shows approx 85 Ft Lbs on the torque and 32 psi on the Yokohama Max Geoland Air H/T-S Size P265-70R16 Tires.

My Owners Manual shows Lug Nut Torque @ 110 and Tire PSI @ 32. I complained initially about the T4R drifting thinking alignment was off. It checked OK and I was recommended 40 PSI tire pressure which worked better.

I am asking for ranges because I feel there are variables due to types of wheels and sizes of tires. Both of mine are stock IMO. I checked all lugs for 110 FT Lbs and all were “slightly under”. * Do I need to re-torque with less or 110 Ft Lbs is OK? * Is the sequencing patterning critical when checking or re-torquing. * Approximately at what Torque Ft Lbs will stripping or pulling threads start?

Thanks For Any Help!!!

I torque my wheels at 85ft/lbs and run my tires at 40 psi and that seems to work for me. :noidea:

:iagree: 85ftlbs is what the Haynes manual tells me. I run my psi at 44psi but I am running LT265/70R17 which I changed from stock 265/65R17

lugs at 85 and tires are at 40. PSI on the tires is really going to depend on the tire. Stock is generally 32ish. Mine are rated at 51 for max load and 40 feels a little soft so I might try bumping them up to 44. P rated tires.

Thanks For the replies!

I guess backing below 80 torque and coming back to 85 torque in a pattern should be all that's needed? Plus I’ll ck my snapping Sear's torque wrench against my pointing to values Ward's wrench (Sears vs Wards) LOL! I have never liked trusting a torque wrench (even Snap On) but I learned to respect them rebuilding VW Engines in the 70s. With head bolts at 26 ft lbs.

When I bought my AT3s the tire place set them at some apparent random value. I called Cooper and they said to run them at the rating on the vehicle door. That's what I have been doing and it's quite a bit less than what the tire states if I remeber.

The PSI number you find on the side of the tires is the MAX recommended pressure, not always the best for daily driving. I would start with the number recommendation on the door frame info label, and adjust from there if you like a softer ride (lower pressure), or more control (higher pressure). But I would suggest that you don't go too much lower than the Toyota recommended rating or tire overheating and possible failure could result.

Depending on the tire, load rating, and size, the factory recommended psi may no longer be valid. If you upsize your tire and switch to a LT from a P, running the psi on the door frame may result in terrible wear on the tires. There is a lot of advice for how to find what pressure you should be running, also a lot of varying opinions. I like the chalk method to see how the tread is contacting the pavement.
