Can Acura adjust my speedo for 20 inch rims? I know you can for some american cars but not sure about foreign. Any help would be great. I would hate to have unnecessary(sp) mile put on my car. Then again it's worth it to look good!

 

Are the tires the same diameter, if so, you don't need any adjustment.

 

No wheel/tire combo is the same as stock...some may be similar, but not exactly the same. Also, if you notice, most (I think even all) people on here with 20's use a 35 series tire...a 35 series pairs with 19's; 20's would take a 30 series to keep the wheel/tire height similar to stock.

There are some websites (check for links in the Wheel/Tires subforum) that will tell you how much your speedo is off based on stock vs. new size. If you know it's 5 mph, for example, just keep that in mind. As to whether Acura can adjust your speedo, I doubt it, but I'll let the folks with more technical knowledge of the TL give a definitive answer.

By the way, with your wheel/tire combo being larger than stock, you'll have lower miles!

 

I had asked my service dept. and they said it cannot be adjusted.

 

what about that tire option in the navi setup screen?
