I was just wondering on how many landings a commercial jet can get on each tire before it needs to be taken off and put on with a fresh one...I would think it would been done numerous times...but tires are expensive....so tell me your input...

hmmm... Heard something on the history chanel a while back.  I think it was somewhere around 60 or 70 landings for a 747.    tire cost was somewhere in the 700 dollar range.

But who knows how old that program was

Tires are changed based on wear on many planes...just like a car, only there are very specific tests to see how much wear is left.

Depends on the workload. C-172 tires can last a good long while if you take good care of them. The tires on the 777 (which are well over 6 feet in diameter) only last around 100 landings (which is a critical wear period obviously). Most tire manufacturers take the old tires back and melt the down and reform the rubber into a new tire, so the airlines get discounts for turning in their old tires.

It depends how many heavy landings occur

Braking techniques and conditions can also affect tires quite quickly.

Fortunately, our local airfield has a grass strip running parallel to the main tarmac runway, so many pilots use the grass strip to land on if conditions allow, rather than the hard runway, in order to extend the life of their expensive tyres.
(This applies to tricycle arrangements as well as tail-draggers... ...)...!

Cheers all... ...!

i think i once heart something about 200...but that was perhaps 100 take off and (hopefully) 100 landings...i don't know.

of course it depends on the weight of the plane, how smooth pilots land it, temperature and roughness of the runways and so on.  ;)

It was diplayed on my flight today.

I can remember when the Boeing 747 first entered service the tyres lasted 2 landings on average. The tyres cost
