Not unless you change the aspect ratio. For instance: If you have a 215/70-15 tire and you replace it with a 255/70-15 this would be a horrible swap as the 255/70-15 would be 7.58% larger in overall diameter. It is never advisable to go over 3% difference in size. Besides your speedometer would read 55.4 at a true 60 mph. If you want to install a 255 tire you will need to install a 255/60-15 to replace a 215/70-15 which is an excellent swap.

Absoulty not if the 255/70-16 is the OEM tire size. The 215 will be 13% smaller in overall diameter. You should never, ever go over 3% different. You would have to go to a 275/60-16 to even be close to 3% and then it would be 3.5% smaller.
Yes
can i replace a p255/60 r15 with a p215/70 r15
That is a very close swap, so yes.
should grand. Its only the profile that's different.
Probably not because of the rim width. The 255 is a wider tire.
Yes you can
From Austin: About 215 miles. From Houston: About 255 miles.
No, this is a very bad substitute. If you go to a 85 series tire which I highly recommend you do not do, you would need to install a 215/85-16. Another good substitute that would work well is a 235/75-16.
