You are right.
A can of glue and a air compressor that is powered by ciggy lighter.
Not the best. I got a punture in the side wall which resulted in a small leek. Could not repair so a replacement tire was required.
In my option the damage was bad enought to have a blow out. As it was on the inside side wall I did'nt notice it untill I check the air pressure and it was down by 5pds. Took tire off and found the damage.
260.00 big bones ouch!!!
