I think 36 psi is too high. In the long term the tyre may wear heavily on the inside instead of the entire tyre surface due to overinflation. Personally, I don't trust mechanics after they finished working on my car. I always watch them like a hawk. Reason, I found out they they almost never check the pressure when they filled it with air. They simply filled it and not bother at what the pressure is. When I had new tyres installed, they were filled to 40 psi!!

Just stick to the manufacturer recommended pressure. Engineers have done it for a reason.
