Question about Revs/mile

I have a 2003 330i ZHP with the following Michelin Pilot Sports:

Front - 225/40-18 Revs/mile=821
Rear - 255/35-18 Revs/mile=824

I have a set of AT Italia 17X8 wheels that I want to use for Auto X and Track events. I plan to put on 235/40-17 Kuhmo Ecsta V700's. The Revs/mile for the Kuhmo's is 855. What effect will this have on the car?

Also, I have a three 225/45-17 V700's. Two are in really good condition. I want to use two of them on the front and order two 235-40's for the rear. When the fronts wear out I will replace them with 235's. Any thoughts?

It means that you will have imperceptably lower gearing.

Right, these are not large difference in 'real' feel and handling. All work fine and are popular choices for R compund tires.

Don't worry about it. It is well known that BMW speedos are overly optimistic to begin with.

There have been threads about this here and on other boards. Car and Driver had an article about speedos in general about a year ago.

Car and Driver Speedometer Article

Summary of Results (check out how the BMWs tested comapre to the other makes)

the actual measurements for a particular tire can be found on the tirerack website by clicking on "specs" on the page describing a particular tire or by finding the specs on the manufacturers website. for example, compare the diameter of any two same size tires on these two charts:

Bridgestone RE750

Yokahama AVS ES100
