Original rims are only 3.5" wide. 155/80/13 is pushing it on original rims. The 8 spoke 5" wide max is 175x70x13, A 5.5" Rim can go 185x70x13.
Check the date on those tires, if Mfg Date is more than 5-7 years old, throw them away. And check for the UTOQ Code to see treadlife 500 or 600 UTOQ 65,000 MileTires are great for MiniVans but not for our light cars. I found some Nexen Tires with UTOQ Ratings in the 200's at WalMart for about $50 installed. They stick well. Look pretty good on my JBW 8 spoke wheels. And depending on the offset, you might need spacers or longer wheel studs. Winners Circle, now located in Cncinnati, can provide both for you.
