When do the tires of an airliner take the most punishment, at take off or landing?
A lot of people would answer at landing but I think it might be at take off. At take off the aircraft is fully fueled and at it's max weight. At the moment of rotation when the front gear lifts the entire weight of the airframe is transfered into the main gear.

well technically not all the weight is on the main gear, most of the aircrafts weight is actually supported by the wings if not all of it, else it wouldnt be about to fly. The higher the airspeed over the wings, the more lift is produced and the more weight the wings carry.
I would still say landing because even though the aircraft is much lighter, the tires and shock absorbers take punishment from the impact of landing, which exerts more force on the runway than a fully loaded aircraft would while taxiing.

Definitely on landing. The tires go from a dead stop to moving very fast in a split second at touch down. I have seen the anti-skid system malfunction and lock the brakes and some tires blew out. Aircraft are capable of higher payloads than they are allowed to carry. For example, Air Force aircraft have a higher weight limit in war time than in peace time.

Yes Its seems like a lot of loading but the real problem would trying to re-land right after take off.The aircraft would have to dump fuel overboard from there tanks to get the aircraft under the prescribed landing wt.Now don't get me wrong in the case of a dieing emergency that baby will land right then no matter how heavy it is.Then they call out a mechanic to do a over wt.landing inspection.no big deal.

Landing. TIres required for large/heavy aircraft are even designed to flatten themselves instead of blow themselves out. Too much pressure on landing or heat build up and these tires will perform a "thermal let down". Basically opens the valve to deflate itself.

At landing. This is when most tire failures occur (other than running over debris like the Concorde).
