time for tires

[yamahahaha]

this is for my banshee but it could aply to any bike...
i have 19" mxr4 holeshots but they discontinued the 19s so ill get the 18s... i have 16/41 gears and want the bike to stay the same speed wise, how should i switch my gearing going to the 18s?

I dunno if going down 1 size in a tire will make that big of a difference. If it does i would drop a tooth in the back. I wouldnt mess with your front sprocket. imo
