I run mine 32 front/30 rear as per manufacturer spec. (02 Legacy), I have not done it yet but has anybody changed tire pressure? Ratio front to rear? What has it done to handling?

Im running 32 all around, seems to give the car good handling and doesnt seem to make the tyres scream when on the edge of grip either. Dont forget as the tyre warms up the pressure in the tyre goes up as well and vice versa for the cold.
Please keep this in mind if you live in an area with a big range in tempreture variation.

about 38 front, 37 rear. Better performance I think with a little more pressure..

Hmm then again my tyres are a lot different. Currently running Potenza RE030's stockers in OzVegas.

I ran about 2 pounds above spec on my old 91 legacy, if I ran spec, the edges of the tires wore faster than the centers, I got much more even wear that way.

I'm running about a 2psi front bias on my Toyo P4's. Generally about 39/37, though I have to play with them for AutoX, but at a 40/40 bias I had about one finger width of roll over.
Even a 38/36 is a decent street setting, maybe a pound more with RE92's, it seems a 2psi front bias will help keep the steering wheel a bit more firm, especially as speed increases.

I have Potenza RE050's with 30 all round. I found that if I increase them to high 30's, the steering feels loose and vague, ride is harder but nicer for very fast cornering. 30 for me is a good level for normal driving.

Is 30 even at the recommended rating? I know it's rated higher than that for stock pressures over here in the US.

I am running about 37 up front and 36 in the rear on the RE-92s.

Sube and I run the same pressures. Less casing flex and squirm, less sidewall rollover are the benefits. Turn-in is also better.

While I don't (yet!) have any experience with a LGT, I did find noticable improvements by playing with the pressures on my MCS. Not just handling, but also fuel economy.
At one point I was down in the 28-29 PSI range; bumping that up to 37-38 all around made a world of difference both in terms of sharpening the feel and adding a good 5-10% to fuel economy. It's shocking how much difference a few pounds of air makes!

It also helps in winter conditions playing with them for optimal snow handling.

So I guess I should up the pressures to 39/37 on the RE92s tonight and see what happens...

I'd suggest it. I sure wouldn't want to run stock pressures on those RE92's if you want feedback.

35 all around on the RE92's. I like it.

The door labels suggest slightly higher but I like the softer ride for city driving. It also steers better and feedback is nicer. Fuel consumption is higher though. When I had them at 38 the car felt too stiff and steering was wild. Perhaps I'll play around a bit more.

You may wear your tires out a little faster, at least th sidewalls owever. I would suggest reverting to stock. Heat is more prone to building up and you may be more prone to having a blowout if you go on the highway for some time. Think of the Ford Exploder.

Thanks for the reply, I will try 38/36 to see how it changes handling. :wink:

I been experimenting and have found a happy middle ground at 36psi Front and 34 Rear on my '02 GT wagon. I agree with the consensus, the stock recommended pressure seems too low. I was getting a lot of inner and outer shoulder wear with the stock pressure. I especially like the better gas mileage and handling with the higher pressure.
Side Note: The SCCA has a few links/pointers on their website on how to set-up tire pressure for best handling.
