I got my 1st pucnture in years abit fed up because they were slime tubes,pre done ones, luckily not to far from home so walked abit.Now on my old cb bike i put the slime in myself and never had a puncture that i had to fix in 18 years.Any way removed the offending thorns that the council left on the path and used some self adhesive patches.Dont know if there any good.Maybe look at the tubless option one day.
