17" rims and fuel economy - Toyota Yaris Forums

MadMax · 12-18-2008, 12:12 PM

I didn't get that message, and numerous people on here have put on 17" wheels without problems. Plus, I may be relatively new to the Yaris; but this isn't my first rodeo! The Yaris is light enough and the brakes adequate to handle the larger wheel. You may lose a little lower-end acceleration but you gain it back on the upper end.

As for Jeeps, I hope he regeared more than his speedo if he offroads, as his differentials are going to explode one of these days if he puts the stress of 35s on them with the stock gearing! He needs to regear to 4.88 with 35s to get the low-end back. Without that, he'll be very slow off the line and be downshifting at every hill even if he doesn't offroad.
