torque on demand problems

You do NOT want to inflate your tires to the maximum pressure on the tire walls. This is a pretty common mistake. The pressure is based upon your vehicle and this info is inside the door jam on the drivers side. Setting your tired to the max pressure on the sidewall of the tire will wear out your tires faster, cause poor handling and will also not allow you to brake as fast.

We'll have to agree to disagree on this one. What's posted on the door jam is for the tires that came on the VX from the factory. After replacing those, you should always follow the recommended pressure rating molded into the sidewall of the tire. The tire manufacturer knows the optimal pressure for performance/wear/safety, not the vehicle manufacturer.

Here's what Goodyear recommends:

To find the proper air pressure for your tires, look in the vehicle owner's manual, on the sticker on the driver's side doorjamb or in the glove box. If you buy new tires, be sure to learn the correct pressure from your tire Retailer or the owner's manual of your vehicle. Check your pressure at least once a month, and use a high-quality air gauge.

If your tires are significantly different than stock, that may not apply but the maximum may not apply either. The correct inflation is a combination of vehicle weight, tire stiffness and driving conditions and will vary for the same tire on different vehicles.

IMHO - Start with the recommendation on the tire. Chalk the tread of the tire & drive about 25 ft. Stop and see what the chalk looks like. If the outer edge of the tread have the chalk removed, add air. If the inner part of the tread has the chalk removed, let out some air.

After that, some minor adjustments can be made to tire pressure for ride comfort/fuel consumption/tire wear ...
