does anyone know if tire companies have a specific 'season' for putting out new tires?? i heard that the michelin pilot sport a/s is an older model tire and will soon be hard to find while the hx mxm4 is a new(er) tire model--

and does anyone know how much a full spare will cost and where the best place to find one is??
thanks and merry christmas/hanukkah/holidays in general

 

are you looking for a full size rim as well as a tire???? The rim will probably be have to purchased seperately, not from the dealer (that would cost too much) but there are places online that sell replica rims... like 200$ or so(depends on what size your stock rims are, 17s or 16s).
For tires..... I suggest www.tirerack.com Some of the best service and prices on the net. I just ordered a set of all season performance tires Dunlop SP Sport A2.

 

The Pilot Sport is the NEW tire, it replaces the XGTV4. As far as a "new model" intro for tire mfg's - not sure.
