Tires should be rotated every 7500 miles for good even tire wear and tire life. Remeber only rotate tires front to back on the same side of the car....no cross rotations. Example: right front goes to right rear..... left front tire goes to left rear and vice versus.
On average you should rotate your tires every 6000 mile or 6 months.
It's a good idea to rotate your tires every so often.

It is recommended to rotate and balance every 3000 to 5000 miles
I recommend you rotate the tires every 5,000 miles and balance and rotate every 10,000 miles. Important: Air the tires to the PSI listed in your owner's manual or on the driver's door post.
You should rotate your tires more often.
6000 miles is the usual recommendation.
In my area it costs $20-$32 to rotate and balance the tires.
Your tires would definitely have to rotate if you are speeding !
Rotate tires 2 front 225 and 2 back 245
Sure, you can balance the tires. Any place that sells tires can balance your tires. You cannot rotate the tires as you have already stated they are not the same size. Balance but do not rotate.
Auto tire rotation often comes at the grand price of free. If you return to the location where the tires were purchased they will, quite often rotate them for free.
