What are the best size tires for MX? I have 22'' on it now.I want to get the best size without them looking bad with the front 22'' holeshots.20'' or 18''? Thanks!

 

If you want the best performance, get the 18in, because they give you a lower gearing , which gives you much faster exceleration times, and it significatly lowers your center of gravity, which means you can get really wild in those corners you usually slow down for.
