Different Tire Size
Has anybody tried different tire sizes like 215/50/17 or 225/445/17 ? Any rubbing?
oem tire size is 215/45/17 |
225.45.17 yes for 60k, no rubbing
205.45.17 yes. No rubbing also. Using run flats right now. Next set is going to be 225.45.17 run flats |

I'm going to have to check that out next time I get on the freeway.

Quite the opposite. I switched to 225/45/17 to help correct the speedo. On the stock 215s the speedometer was way off. You can set the speedo at 70mph but multiple GPS monitors will show you are going 66ish.

I run stock tire sizes and have a GPS module on my dashcam. It consistently shows I am going 2 MPH~ slower than my cruise speed at highway speeds.

I will see what mine says today. If is off will definitely be going to a tall tire.

Most cars run conservative. My CT shows 2mph slower at around 45-50mph. I know because the digital sign I drive by that pegs your speed as you drive by lol. Same thing in my IS200t. And same thing in my past BMWs. Around the same. The delta gets wider as you go faster though. but not by much.
The car makers possibly do this to account for tire wear? A theory. They certainly wouldn't want to be held accountable for all their customer's speeding tickets. imagine all the claims. Or could be to save you from getting speeding tickets. Both are pluses I guess |
Tested mine today; under 60 is spot on, 60-70 is only -1mph. Stock 215/45/17.
