40 series should keep you okay with 17's. I checked my speed with a radar at different speeds and my mph are only off from the radar between 1-3 mph depending on my speed.

you only need be concerned with speedo gears when you adjust the height considerably (the 1st large number)
255-50-r17....thats what id shoot for</font>

For example, a 245/50/16 tire is taller than a 245/45/16 tire since the 245/45 tire is using a sidewall that is 45% of the cross section. Both numbers are important, not just one or the other.

A 255/50 R17 would be too tall. You'd need a 45 or 40 series tire to maintain the 26" height.
