tires>all. Even if you can't replace the struts right now, you can't keep rolling on those crap tires. If it blows while you're on the interstate...it's just not good. I drive at high speeds therefore i make sure my tires are always wearing correctly etc.
Just get you a decent set of tires and save for struts. I had blown struts on my last prix and if you hit a dip it was just bouncyfloatbouncyfloat.
Sure, the blown struts WILL wear the tires quickly. But not THAT quickly, so try not to fret. But on that same token, don't buy the best of the best tires lol and waste your monies.
