I have a friend who is an engineer working a specific issue regarding the A380 and he was wondering what the contact area was for each tire or the pressure exerted by the aircraft on the contact surface of the tires. Can anyone here help? Thank you.

That infromation can be found in the Airport Planning Guide. Information on the Airport Planning Guides can be found here:

The tires are inflated to 16 bar (230 psi)
The plane weighs up to 1.25 million pounds
The weight is primarily on 20 MLG tires
(1.25 million lb / aircraft) / (20 tires / aircraft) = 62,500 lb / tire
(62,500 lb / tire) / (230 lb / square inch) = 272 square inches

So the contact patch is approximately 19 inches in diameter.

(With my apologies for using barbarian units.)
