Title: Just added 17" rear
Post by: Sparkie on May 16, 2011, 08:35:49 PM

First of all a big thanks to all the guys that came up with this mod. I found a used Kosman wheel last year and finally mounted up a new tire this past weekend. Very nice upgrade as I was able to put on the Avon Storm dual compound tire. So far I'm very impressed with the handling. I mounted the 160/70-17 tire which is a little taller than stock and noticed a slight lowering of engine rpm at cruising speed. Thats a welcome change too. I'm wondering about speedo calibration now. If the 160/70-17 tire is a little taller than stock, is my speedometer indicated speed closer to being accurate? Or is my indicated speed now further off? Thanks for any help, Mark

 ??? Thanks T-Cro, that makes perfect sense when you put it like that.

Thought so.....  :rotflmao:

BTW I run a 120/70-17 on my ZRX front end and my speedo is only off by 2 MPH on the slow side..... The 130/70-18 tire mounted to the original wheel used to cancel out any speedo error before I made the swap.
