Those are really small tires. 245/50R18 is the same rolling diameter as stock. 245/40R18 is 7% smaller than stock, your speedo will be quite a bit off, and your spare tire will be incompatible with use should you need it.

They are also likely to look really weird with no suspension modifications.

Do you have the specs for the wheels? It's likely they'll work but width and offset are worth considering.
