265/35/19 will look just fine on 10.5, esp if you are running PS2s.
It might look SLIGHTLY stretched, but far from being look bad.
265/30/19 & 285/30/19 have significantly smaller OD then stock, causing...
1. shorter gearing
2. worsen ride quality
3. increase wheel gap
4. affect handling character
If you are getting 19in wheel, stock tire size is pretty much only choice for now. (unless you downgrade to less tires)
