If the tires are the same size then yes.
I have a 2002 Nissan altima with tires 205/65R16 can I replace them with 215/65R15, the tires came on 5 bolt rims and will fit on the altima. If the tires are on 15 inch rims, you are ok. You can not put 15 inch tires on 16 inch rims, or 16 inch tires on 15 inch rims.
If they are normal cars there will be 104 tires
Yes, that is an acceptable swap.
Yes, that is a good swap.
Yes this is an acceptable swap.
Yes, that's a reasonable swap.
Since cars were first made tires were always rubber.
A burn out will ruin tires on race cars by burning up the rubber. The rubber of the tires will get worn from the friction of the pavement causing the tires to tear.
No, this is a very bad swap. Your speedometer will read 57.8 at a true 60 mph. This swap will adversely effect handling, ride, and performance.
Many European cars use 14 inch tires.
Tires or the road.
