Of course you can but this would be a terrible swap. If you want to go with a 60 series tire then go with a 255/60-16 if you have no side clearance issues as it is a good swap.
NO, the rim size is incorrect.
The 205 60R is a narrower tire than a 215 60R 15, however they will probably both fit the same size rim.
NO, the rim sizes are different.
Yes, they will, - and if ever they won't , all tire shops will tell you. -They don't want to be responsible for fools fitting wrong tire/rim combinations.
Not if the OE is 215. A 205 could be too narrow for the rim. Depending on what type of vehicle it is you may be able to go up to a 225 but then the middle number must drop by 5. Example: 215/65/R15 could be replaced with a 225/60R15. Again it depends on the make model and year of the vehicle.
Yes, it should - but it may not fit in your wheel wells, and will definitely throw off your odometer and speedometer as well.
No, it will not.
Yes, you can mount 225-60r16 tires on a rim made for 215-65r16 tires.
Of course you can.
The only difference is that 215 tires are taller. The first number in the name (215) indicates the tire sidewall height, the second part (55) is the tire tread width, the third part (r) shows that the tire is a radial tire, and the fourth part (16) indicates the rim size.
No, 21570R15 the 15 means that tire fits on a 15 inch rim 21565R16 the 16 means 16 inch rim.
14" rim: 185/65/14 15" rim: 195/55/15 16" rim: 205/45/16 17" rim: 205/35/17 I recommend you stick with 14" or 15" rims.
