Yes, the 215 70 r 15 fits early models of the Alero for sure, maybe all.
The tire/rim size of a 2003 Oldsmobile Alero is listed right here. Tire Size - 215/60/R15" The rim size is 15 inches, so I am not sure about 20 inches. You might want to consult a Mechanic.
No, it will not.
No, it will not.
Yes, the 65 tire is only slightly taller.
I tried to fit the chains for a 215/70R15 on a 215/60R15, and the chains were too large. I suspect in your case the chains will be too small.
Olds Alero with 2.4 (LD9) engine!
yes they will with a low pro tire
I doubt it as there is 2" difference in diameter.
Very possibly, most chains will adjust up to 4-6 inches in circumference.
Yes, you can. Check carefully for any rubbing while steering and ONLY fit as a pair.
They will fit but your speedometer will be off.
no i dont think so i got 20's on my 2001 alero and i only got about a inch left from the top of the tire to the bottom of the strut and a only got a 225/30/20 tire The tires/rim size is listed right here. Tire size - 215/60/R15" Rim Size - 15" So I am not so sure about 22 inch rims. You might want to consult a Mechanic.
