BRAND NEW TIRES WORE OUT IN 45000 MILES. ENGIN LIGHT STAY ST

HELLO, SIR
I HAVE 2001 TOYOTA COROLLA. I BROUGHT IT IN 2000 BRAND NEW. IT HAS 108000 MILES NOW.
THE ENGINE LIGHT COME WHEN IT HAS 59000 MILES. I DONE EVERYTHING TO TAKE IT OUT. BUT IT STILL THERE. I HAD CINVETER CHANGE, TUNE UP. OXYGEN SENSOR CHANGE, SO WHAT IS THE PROBLEM?ANOTHER THING @65000 I HAD 4 BRAND NEW TIRES REPLACE. @ NOW 106000 ALL WERE WEARE OUT. SO I DID REPLACE NEW ALL AGAIN. AND DID WHEEL ALIGNMENT.

I AM THINKING THAT IT COULD BE A SHOCKS/STURT BECAUSE I HAVE NOT REPLACE IT SINCE I BOUGHT IT. AM I RIGHT? LET ME KNOW
THANKS A MILLIONS.
ANDY TOYOTA.
