hi sir!
regarding the tires....the size 17 tires are significantly higher in price but still the brand still dictates the price....if you saw my post in the mods thread the prices I mentioned there is for Cooper Mud terrains which is the STT's....now for the 17" AT tires of cooper I think its priced a around 7k its a 265/70/R16 you can buy it at Ryco makati which is definitely cheaper than the pirelli's...
and with regards in replacing the mags, I suggest you just stick with your stock mags and get the tires....but if budget permits replace the also with an aftermarket one thast the best way to go...
with regards to your question regarding the OME's I supposed your talking about shocks right?
if yes, then its ok if you only replace the rear shocks even though the front is still stock....but the ride comfort will be really enhanced if all four are replaced...
