I know this is a newb question beyond belief but my front tire keeps going down have changed 100's of tubes on my BMX how do i go about fixing the mini's front tire ?.
Its the same process as a bmx tire just alot more stubborn so you will want to use some grease or lubricant of some sort to make it easier to get the tyre on and off. I just take it in to my local bike shop and it only costs about $10 for them to change a set of tyres so its hassle free for me.
What brand tyre have you got on it now? If its a cheap china tyre then I reccomend you get something better to help prevent future punctures.
MSO currently have a great deal on tube and tyre combos. You should check it out.
