chalk test
set up:stock 17" rims with Toyo Open Country M/T's 35/12.5 17
PSI: 35
chalked the front and back... looks like there is about a .5 to 1" of chalk on the outside tread
should i drop pressure??? or is this about right since they are on stock rims and they buldge

Not ok! You want the most even wear across the profile. Lower your pressure by about 3 PSI and repeat the test until you get it right.
