Looking to make a purchasethis Friday on a '08 Alpha H3.At my request, the dealer is "swapping out" the stock 32" tires/rims, fora set ofstock 33" tires/rims off of an ADVENTURE PKG equipped '08. My question is: won't this affect the speedo calibration and the accuracy of the odometer? My salesman (sales manager) says "NO". Would like some input before I purchase.

Thank you for your time.

if it does,i doubt it willbe enough to get you in trouble

 

Not much. Do the mathmatical calculation and you will find that when your speedo shows 70mph, your actual speed will be appx 72. Not a significant problem IMO?

The math:



Actual Speed = new tire diameter x indicated speed

Old tire diameter


72.1875mph= 33" x 70mph
32"

 

or you can do the PCM mod, right?

 

I do not think anybody is doing the PCM for tha Alpha H3, yet? Patches had a thread about that, but the PCM could be changed to reflect your tire diameter change. So technically MuddyD, the answer is Yes..... When available or if you HP tune yourself.

 

I just mentioned it to get the interest up for Kelly and the gang... wink wink, nudge nudge...

 

Marketing........NICE!!!!!

 

I do what I can....

 

New purchase best idea. Keep it up.
