Split in Tyre - repair or replace

I had a puncture yesterday in my rear tyre from a piece of glass and am wondering if the tyre should be replaced or can it be safely repaired. The tyre is a nearly new Continental Grand Prix 24mm and the glass penetrated in the middle of the thickest part, just reaching the tube (barely noticable cut in the fibre on the inside of the tyre) but leaving a 4mm or so split in the middle of the tyre. I replaced the inner tube with the spare I was carrying and put a repair patch on the inside of the tyre to stop the inner tube pushing into the cut in the fibres and then pumped the tyre up to 100 psi. The split has opened by about 1/2 mm at the widest part so I don't feel comfortable to ride it as it is but can it be repaired or is it better to trash it and be safe rather than sorry? I have usually been very lucky with tyres and punctures have always been a warning that they need replacing but this is an almost new tyre...

    I have in the past used puncture repair patches on the inside of the tyre to seal up small holes (thorn sized) but I must be honest - not sure I would be confident on a larger hole.

    I would be interested to hear if anyones done similar and theyve ridden ok

    Replace all the way, some things are just not worth repairing. You know it'll fail on you when it's pissing down with rain and blowing a gail on a really bad road.

    I bought last year some specialized armadillos and have not had a puncture since 'I put them on. That was a year ago!!!

    Yip totally agree. Replace all the way.

    I have a set of bontrager all weather which I use for training. Increased resistance on the tyres and they are practically bomb proof. I think they are very similar to the spesh armadillos.

    Has to be one the best purchases I've made to be honest.
  • 2 hours climbing the foothills of the alps outside Grenoble, at the top of Col de Porte, just beginning long descent, BANG, like a pistol, back tyre split. With only an inner tube, I had no way of stopping the inner bulging thru so had to gently trundle down to village. I ve just brought set of Schwalbe Blizzard, kevlar lined tyres which will hopefully keep me puncture free...at least it was hot and sunny.
  • Thank you all for your input - the overwhelming consensus is to replace the tyre as I suppose I thought it might be. I have a dislike of throwing things away that still have some use so I might have a go at glueing the tyre (I have read of some people having success with rubber glue) and trying it out on my hybrid for some shorter, slower trips and turbo use. I really don't want to be in wheretherezawill's position on a long trip if I can avoid it...

    I hate chucking stuff away espec when they are largely unused and you shelled out £60

    got a puncture on a tub which was relatively new and had to replace the bloody thing.

    oh how true...

    on the bike last night and pop - fecking puncture. First one in a long long time. think the tube gave the ghost up rather than anything piercing the tyre as there was no hint of anything getting through.... but sods law..

    Why don't you send the tub away for repair, most cycling mags will have adverts for specialists who repair tubs, tends to cost abouit £10, but it's a lot cheaper than replacing.
