How does one best put ones car on display at a car show?

The best tire pressure for your car should be found in the car manual. Failing that, the car manufacturer should be able to answer the question. The producer of your tires should also be able to supply valid information on the correct pressure. If all this fails, then any reputable car mechanic or car workshop should definitely be able to help you.
