26 psi sounds pretty low to me, Does it not say the recommended psi on the sidewall?

The fuzion tires we usually run 34-36 psi depending on the customer.

I usually run 10% less than the maximum cold inflation PSI (which should be marked on your sidewall) I think your fussions have a 44psi max cold inflation, so 39ish is what I would run for daily driving. But thats just me.

That is really hard to say definitively. It will depend on your driving style, suspension mods etc.

Assuming fairly stock setup...
I would start off with 32 like the door says as you have increased the load rating of the tire from 84T to 88W. This means the tire will hold more load for the same pressure. So running the tires at 32 will already have a built in effective pressure increase. So after starting at stock monitor your tires for the break point wear on the shoulder of the tread. If it gets too much sidewall in your driving style increase that axle 2 PSI and continue on. If you seem to not use the edges at all then decrease the pressure on that axle until nirvana arrives. The remember what your car like with those tires and keep them there.

32...39 is def too high..i used to be a tire tech so and i have these tires....Run them at 32. If you want u can run them a little higher but i wouldnt go to anything over 35 personally but that is just me

Go measure the tread depth on your outside tread blocks and your center tread blocks. I promise you they will not be the same. Your killing your tires.

I used to be a tire tech too and compleatly agree. Sense you don't run the stock size you can't go with whats writen on the doors. So just do as mentioned above and you will get it perfect.

When I had fuzions I ran them at 36 cold.

Weird, 'cause I get perfect treadwear. But again, thanks for your concern.
