Choosing the proper tire size

[NSPHIL]

Hi, I have a KDX220 with an 18" rear wheel and ride in mostly dirt, sand, some mud, and very little rocky terrain. I am trying to detrmine what tire width I should be running. I think I may try the D756 or S12. I see a lot of riders putting a 110/100-18" (130 for the michelin S12), how would this differ from the 100/100-18 other than the tire width. How would they both affect traction, turning, etc.
Thanks guys.

Hi.

I used a Michelin S12 on my Kx 125 '01 130/90 19"
and i was very happy with the traction. I would recommend you to use the S12.
