Im pretty sure they are too inflated for my driving style because of the tread wear, but my dash says they are 36-40ish. Ive heard the dash being as much as 5lbs off though.

 

Yes, the TPM system is not sufficiently accurate to use in place of a manual guage. I can't see the photos in sufficent detail to respond, but, if the tires are over-inflated, you will see excessive wear in the center portion of the tire, assuming no alignment issues. 40 pounds at operating temperature should not cause such problems.

Yes, but they all show just the outside edge, not the entire cross-tread area. Just measure the tread. If the tire is wearing more in the center, that usually indicates too much pressure. Under-inflation usually wears both inner and outer edges. Of course, alignment and driving style affects the wear pattern too. I expect you would have to be in the upper 40's to see premature wear from over-inflation.

 

if you find you are wearing just the outside edge then try some more camber and pressure.

 

From the pics, they look under inflated if anything.

But it could just be an alignment problem.

 

A pyrometer is a great way to gauge this. test the inside and both outsides of each tire.

Difference between fronts and backs, lefts and rights, and inside vs outsite vs center of each tire will tell you what your issues are and how to correct them. Get the book Speed Secrets and it will give you the info you need.

 

Get yourself a good tire gauge and inflate your tires to OEM specs!
