checking in with collective wisdom on tires and wheels

Tabnero

getting bearings repacked today and new seals and break check. tomorrow new tires. just read the manual and it indicates 90psi torque on the lug nuts of by 2021 tab 320s boondock with 15 inch aluminum wheels. Is that was everyone thinks is the proper setting. I thought it was 100psi

I believe you may be referring to foot-pounds rather than psi (pounds per square inch).
Tire pressure is commonly measured in psi.  Torque is commonly measured in foot-pounds.
I torque the lug nuts on my 2020 T@B 400 (with aluminum wheels) to 95 foot-pounds.
Then, after towing around 100 miles, I re-torque at 95 foot-pounds.
To enable quick visual checking of lug nuts, I mark each nut with a small dab of paint after the re-torque.  That way, I can easily see if a nut is backing out, without bothering to use a torque wrench each time I want to check my lug nuts.

Yes - lug nuts should be torqued. I replaced my tires with Toyo  Open Country tires and I keep them inflated to 47psi on pavement and air down to 37 for dirt

@Tabnero, I have always used 95 lbs as the torque setting on my 15" wheels without any issues.  I have seen others post that they use 100 lbs torque for the T@B 400 wheels, but I do not see any distinction between the Boondock wheels on a 320 vs a 400 (other than the weight each carries on the axle, so it makes sense to me to use a higher torque.)

My understanding has been that, in general, aluminum wheels should be torqued between 90-100 lbs.  However, if you do a search online, you will see a range between 90-120 ft lbs of torque for a 1/2" lug nut on aluminum wheels with a 5 on 4.5" bolt pattern, like the Boondock wheels.

thank you everyone. Yes I meant ft-pounds not psi

I bought a set of torque sticks to use with my air wrench.  Barely snugging nuts then using stick I've gotten consistent results, always check with torque wrench.
It's made regular wheel rotation on my truck much easier.  The Tacoma only gets 83 ft lbs, surprising the smaller studs on tab take higher torque.
Both sets are steel.

The generic charts show 90-100 ft/lbs for aluminum wheels and 90-120 ft/lbs for steel wheels when using 1/2" studs and cone nuts. Steel wheels have more "give" and the risk of stretching the stud is less. 
Car manufacturers arrive at their numbers in different ways, taking in account the rotors/drums etc.
