Different Size Winter Tire -will It Matter?

[bobstoc]

I know there have been previous posts regarding this topic, but...

For my 2001 GS430, I have 225/60/16 Winter tires on stock 16" wheels. The original tires were 225/55/16's. Will the taller sidewall make a big deal. I figured the size difference makes the speedometer read 2 mph SLOWER (less rotations). Will this affect the transmission, computer, etc?

I only use this wheel/tire combination during winter months as I have summer tires/17" wheels.

Thanks in advance for any information.

As long as all of the tires are the same size, you will be fine.
