Hey guys I have my P's test tomorrow morning at 8am and i just discovered a slow but fast enough leak in my rear tyre due to a nail its a new tyre! lhardly any k's on it :!: so i want to save it if i can. Due to the angle that the nail has entered from i dont think a plug will work. Apparently there is a goo type formula that is inserted into the tube. Then add air, the good then sticks into any small holes that are there or as they appear and block the air from escaping. I want to go get this goo and use it but unsure if this means that i cannot put a tube into the tyre later on. I dont want to waste the tyre its brand new! Any ideas guys?
