GM Rims Size 17x7.5J
I need a little help if possible with reserch. It was brought to my attention that the rims on my GM pick up may only be able to handle 65 lbs of air max.
The rims are noted as "Custom Aluminum 17x7.5J rims they came stock on my pick up and the truck is a 2008 Vortec Max ( Heavy 1/2 Ton). I have been on the GM web site, in my hand book for the truck and I was not able to find anything about the rims, now the last thing I did today was call the dealership where I bought the truck new and spoke to the Service Manager while I was on the phone with him he was on some kind of spec site for GM and came up with nothing, so I ask him if he could check with some of his Mechanics and see what they come up with, well he called me back about an hour later with some info his Mechanic said that the rims would have no problem handling 80 psi but they did suggest coming in and re-program the tire sensors, the next question i ask was about the valve stems...would they hold up under high pressure and he said that they should be ok but when I bring the truck in they will check them out and let me know.
Now the reason for all of this is because I changed out the stock tires that came with the truck from ( P26570/R17) to ( 26570/R17E)....From 4 ply to 10 ply. So I have been told by the Masters themselves at a GM dealer that thy well be ok....Buuut I would like to see it on paper. Thanks in advance...
