I have a question that has been bugging me for a while now. Changed out my stock 21" wheels for a set of AMG forged 21" wheels, and I am noticing faster wear on the middle of the tire with the recommended 32 PSI. I have gone online to get a better recommendation of the right wheel pressure. Loking at the calculation below, it is suggesting that I take it down a couple of PSI. 29/30 PSI seems rather low. What do you guys reckon?
If you could determine the real axleloads in your use, you might see that OEM tires pressure was already on the high side.
Then going to higher loadindex tires, brings same pressure over the edges where centrewear occurs.
So mayby 25 psi is enaugh, and more comfortable ride.
Can make you list to look back 99% acurate determined axleloads, for pressure with max reserve, at wich comfort and gripp still acceptable. You could begin by looking back GAWR's in it.
