Tire switch from a passager vehicle to CRV
Presently I have 4 new tires on a 2004 Toyota Camry: 205/65/15 and would like to put them on my 2004 Honda CRV: 205/70/15 and vice a versa. Will I have any problems as far as handling the car and CRV, not fitting the wheel wells, safety?
At first glance, it might seem that both these tires are similar in size, but in reality they are not.
The key is in the second number in their sizes the 65 and 70. These numbers are percentages which are used to calculate the tire's height from the first number (205) which is the width, in millimetres.
Knowing this you can see that there is a 5% difference in the height of each sidewall, and this produces an overall size difference of more than 3% in the two tires. This, in itself is a signal that the swap is not a good idea since we generally do not recommend installing tires that have a difference of more than 2% for best results.
In addition, you may have to adjust the air pressure in each of the tires to compensate for the difference in vehicle weights and there may be some differences in speed and load rating for the two tire requirements of the different vehicles.
In short, while the swap might work, I do not recommend it.
