need tire and rim size help

Yup... 225s could work on the front too. 225-60-14 would be a bit shorter than stock. 225-70-14 would be taller (You may or may not have tire to fender interference with a 225-70-14 on the front, can't really tell without mounting them, cus its not the same for every car even if its the same kind of car)

what would i have to do to change to 15" rims i have 8.75- 3.55- 489 rear end thanks
