1998 Saturn SC1 shaking

As I was driving on the freeway goin 60 mph I ran over as object on the road. It hit my front tree but only dented the rim an not popping the tire. The object also hit my back tire which also dented the rim but more majorley and popped my tire. So I bought used tire and rim fr the back and a nnew rim for the front an putting the old tire on the front rim.
thje problem is when I strt going faster my steering weel starts shaking. Ter mor faster I go the hrder it shakes?
