i have 4 mounted snow tires 205/70/15 from my 95 monte carlo, can i use them on my new 07 impala tires are 225/55/17 there seems to be about 1 inch difference in size maybe less
Based on this, there should be about 1.5 inches of difference in diameter, which will increase your “gear ratio” by about 6%:
It depends on your bolt pattern and offset of hubs. Your speedometer will be a good deal off.
If the base OEM tires are 15" and you don’t have oversized brakes, then they should work. You’ll have to fit them to be sure.
