Correct Tire Pressure for Yokohama AVS ES100 on Stock Wheels

Hi guys,
I've been using Yoko AVS ES100 tires, size 205/60R15 on the stock wheels with great results. Car ride and handling is awesome.

My Tire Rack invoice recommmends 37 psi for "proper load capacity". This is higher than the stock tire psi.

Toyota doesn't think so, however. They always deflate my tires down to 32 psi when I go there for service.

So, who is right and who is wrong?

At 32 psi ride quality suffers considerably. First time the dealer did this, I was unaware, and drove a few miles in this condition. The ride was so bad, that I thought my shocks and struts were shot. I then noticed the lower pressure.

Any comments?

I have the same tires with stock wheels. I had them balanced and mounted at Wheel Works. The installer recommended 34psi at cold. As I recall, the max. cold tire inflation pressure is 40psi, so 37psi means you're pushing the higher end of the load capacity. I don't really think it's necessary or beneficial to go that high for regular driving or hard driving though. If you aren't weighing down your car with a whole bunch of people or a massive audio system, I think you should go lower. Maybe not as low as 32psi, but 34psi like me should be fine.

You've gone to a wider tire than stock, so the correct tire pressure will be lower than Toyota's recommended inflation pressure (30 psi). The math says 27 psi is the right pressure, but I would go more like 28 or 29. If you inflate more than that, you will get a firmer ride and better handling on dry pavement, but your wet pavement handing will suffer and the tires will wear out more quickly.

Is there any set way of finding out what you r tire pressure should be at??? I have 16"celica gts rims on yokohama avant 205/50R16 87V, My tire pressure is 26psi. The ride I feel can be better, but I think it is b/c I am still on stock springs, any comments???
