Up front, preferences for both the 225/65s and the 245/60s.

Can anyone explain the pros and cons here?

Again, many thanks!

SascoSports lists both as 26.7" tall. http://www.sascosports.com/tires_sea...im_diameter=15

Both have essentially identical heights / diameters, so that's a wash. Section and tread width for the 245/60R15 are wider by 0.8" than the 225/65R15, so that's a consideration if clearances are limited.

Worth noting is the 'Approved' rim width for 225/65R15 is 6.5"-8.0", with the 'standard' width being 7.0". For 245/60R15, the 'Approved' rim width is 7.5"-9.0", with a 'standard' rim width of 8.5". If you're running 7" wide wheels you're therefore limited to running 225/65R15. Conversely, if your wheels are 8.5" wide, then you'd need the wider tires.

The extra tread width on the 245/60R15 tires will increase turning effort at low speeds - which may be a consideration if you're not running power steering. The extra width should also increase grip at the front end which will affect your handling. If your car is already neutral in its handling, then wider tires could result in oversteer. If you're experiencing understeer, then wider tires will help to reduce that. IMO, for a car running 295/50R15 on the rear, 245/60R15 seems like a better match than does 225/65R15.
