Versa 1.6 upgrade wheels and tires from 14 inch to 15 inch

[blockmap]

Hello, I have a 2009 Nissan Versa 1.6 with 14 inch wheels and tires and would like to upgrade to 15 inch. Will 15 inch wheels fit and will they change the speed and/or mileage? Thanks, John

Theoretically, as long as you maintain the same outside ("rolling") diameter, your speed and odometer readings will not be affected.

But since the 1.6's 14s are so tiny and narrow, it might be hard to find a tire with the same rolling diameter in a 15'' tire. Fortunately, a lot of Miata tires are in the 205-50-15 range, which is about where you want to be to keep your speedo accurate. You'll probably end up being off by 1 or 2 mph at 65, but no more than that if you stick in that size range.
