can i put 17x9 rims and tires on a 1986 lx without any problems?

 

yes and no

while a 17x9 wheel will fit, your front wheelwells are so small that your car will rub while making a sharp turn, especially if you run the proper size 245/45/17 tire in front.

You may be able to get away with a 245/40/17 in front and a 275/40/17 rear
