I have been looking for a certain post for a few days with no luck. There was a post a few weeks ago or so (I thought) that had a chart of the different tire sizes (275/35/19, 285/30/19, etc) and by what percent +/- your speedometer and odometer would be off and the likely hood of vdc problems and stuff. If someone knows where this thread is could you please relink the original post here for me? It is driving me crazy and I need tires ASAP! I had it saved on my favorites but that harddrive crashed so I lost it. Thanks in advance.

 

Go to tires.com and click the following:
-at the store
-info center
-tire calculator
then enter all the info on the tire sizes and it'll give you all the info you need.
hope this helps
