looking into getting some new tires. what tires do you like or have? and what size? i heard the 18's were good but you lose speed, which makes me think to go with the 20's, im not sure

 

I have Razr 2s all the way around my dale and i love them i think they are the best tires I have ever had, they hook up in everything i have 20s on the back and 22s in the front

 

I would suggest the 18s if you are mx racing but otherwise my friend has 18s for woods riding for some reason and the ground clearance is greatly affected and he gets stuck up on dirt and other things alot so I would suggest the 20's as thunder said either holeshots or any of the razr's I would suggest for hard dirt and sand well paddle tires.
