Buy tires and keep car for 12-36 months, or replace car now? 
There are a few factors I like to consider when I'm reasoning financially over my households cars. How many KMs will the car travel each year because I like to factor in how often tires will need to be changed, how much tires for my models cost as well as how gas efficient they are. Knowing how much the car is driven and in what environmental/road conditions is also important factors to know because that will help guestimate possible repairs cost. Also possible taxes should be taken in to consideration. For example a few years ago I had a diesel Citroen C5 that had yearly taxes of roughly 500$. The replacement costs only 150$ a year in taxes. So switching cars 3 years early would have saved me 1050$ in taxes. So some information on possible taxes, how far you drive each year, what environmental conditions, type of driving (daily long rides or just short etc..) as well as the fuel efficiency of both cars would help to better calculate your costs for say three scenarios. Car change in 12, 24 and 32 months respectively.
