tire size

[nramike]

My mechanic is telling me to put larger tires than stock on my 98 superglide, is this OK? Will it effect handling?

I don't think your speedo will read true but it shouldn't hurt anything.

How big?Yes it will have an effect on handling but size determines how much.

Good points and one more to think about is a bigger tire will grow more at higher speeds and can contact bike parts. Not an ideal situation. One size bigger will usually be OK. I've done it when replacing tires on a previous bike and it rode and handled a bit better.
