  • Perfect fit
Size: 60/100x10 (2.50x10)
Easy install I let sit in sun for few hours to soften, looks like good quality will see how they last

  • Decent Tire, Good Basic Lug.
Size: 70/100x10 (2.75x10)
Used on rear of a Honda XR50R. Could have went a little wider but this will work just fine. Mounted good using spoons for installation. Pleanty of lug. I did drill rim and installed a bead lock which it did not have. Be sure to get a new tube... fit and functioned as expected. Quality seems good for a tire this small and price was not bad. ... show more

  • Good tire. Like, I was looking for the cheapest tire i could order
Size: 70/100x17
Amazing tire for 40 bucks. ...I expected an extreme, either hard or soft rubber but it's decent. Better than expected. Gonna order the back one soon.

  • Great tires for SoCal MX tracks and all loose dirt tracks in general.
Size: 70/100x19
A much needed upgrade for my 79bike Falcon Pro. The stock tires are great for street and light trails, but I shoot MX riders on MX tracks and the stock tires would slip and slide. Purchased a rim stop and keep the tire pressure around 15 lbs and I'm good to go. I think these tires will work great for anyone riding in SoCal with all the loose dirt. ... show more
