You can use the 245 mm wide tires on the front, if the rims are wide enough.
In the back, because each tire will be almost a inch wider, you can not use them, they will exceed the allowed space between the tires, and not leave any space for the tires to bulge at the bottom without touching each other, and causing tire damage. You would need about 3" of space at the top of the tires to have space for 1" wider tires and still leave a inch between the replacement tires once everything is mounted and done.
You also need to check the date codes on the used tires. If they say something like 2110, then they are manufactured on the 21st week of 2010, and are only about 3 years old. If it says 0808, then it would be the 8th week of 2008, even if the buyer bought them in 2009, the tires are now 5 years old, and will require replacement in only a few more months.
