I recently locked up my front brakes on my motorcycle. Causing it to skid for about 25 feet. Do i need to replace the tire?
No, as long as the tire looks and operates the way it should. I find it hard to believe that you skidded the front tire for 25 feet and didn't fall down!
no just look at the condition of the tire how did you mange to control the bike?
Skidding can cause FLAT SPOTTING, in severe cases enuf to vibrate, I think you will be alright, go back to riding like normal, if the bike shakes or bounces, then replace the tire.
