Puncture repair-does it downgrade the speed rating

[5 wh]

I had a puncture repaired on my bike today.When I collected it I was informed that as the tyre had been repaired then the speed rating was now lower because of the repair.It doesnt really make a difference to me because I never ride over 70mph ,but is this true??

ive done trackdays in the past on properly repaired tyres with no problems

as long as the repair was this sort of bung (mushroom type) you will be fine

I've been tols ot to exceed 50mph on a repaired tyre (using one of those kit thingy's). Has someone just made this up s a precaution??!!!

the one i showed is not a kit one, its a proper trade one as used buy car and bike tyre shops


ive used to work in the trade and used loads of repaired tires on all sorts of bikes without a problem


at the end of the day its up to you

Manufacturers do not reccomend tyre repairs these days because of the sue society. How does a tyre manufacturer know how far the tyre was ridden on while it was flat? Potentialy damaging the carcass. So its not really the plug thats in question, but the integrity of the of the tyre as a whole. However they arnt illegal, but you guys now whether you have ridden that tyre 20 miles flat as a pancake therefore destroying all the items in a tyre that were bonded together...

ive approached warp speed on repaired tyres a few times - in fact didnt even know the tyre was repaired till i replaced it.
the DIY bungs id be wary of but a proper repair should be fine.

Same here, but I wouldn't use those DIY bung type things, they are rubbish.

Got ya! Soryy for the ignorance!

i know a punk who was riding down to cadwell park for a trackday and got a puncture. we got to a services before it got really low on air pressure. he bought on of these repair kits where you fill the tyre with foam from the aerosol. the foam plugs the hole.

he was busting laps all day then road home on it!

Proper trade repairs to the rear where the tyre comes off the rim to fix of which I've had many I've never been told about any speed restrictions.
However on those temp plug things I've been set 40-50mph limit and made to sign a disclaimer by the AA in the past. Basically I only ever use plugs to get me to the tyre place to get it fixed properly.
My current rear diablo is sporting two pro repairs currently but then the majority of my miles are round London with a 30 limit. Its my second tyre that I've run two fixes in, my basic rule is if it gets a third it gets junked. Also the tyre place won't repair a second puncture in the same quarter of the rear.

I've just noticed today that my front tyre (on the bike when I bought it) has what I assume is a repair. I've never had a tyre repaired before, either professionally or DIY so don't really know what I'm looking for.

It looks like there is a round 'plug' of rubber, maybe 4 or 5mm in diameter that's sitting almost flush with the surface of the tyre. At first I thought it was just some flash from the moulding process.

Is this something I should be concerned about? The tyre has plent of tread on it.

I've checked the back tyre and it seems slightly squared off, so I'm thinking it may be wise to get a new set so I know where I stand. Though, I'm terrified of the idea of new tyres since from reading online I'm expecting it to be like riding on ice and am likely to end up throwing myself down the road! Also concerned that because I'm still new to this, if I go and buy a new rear, it'll be squared off straight away (I'm not sure whether my current tyre was that way when I got it or whether I've done it...it's not like I've got my knee down all the time, but I don't think I'm riding particularly upright either. Could I have squared it off in the space of 700 miles or so?)

If I knew it was repaired from the inside with a proper repair kit I'd leave it. If I thought it was one of those get you home jobs applied from the outside or simply didn't know I'd change it.

I'm assuming you've just started riding so if there's a definite 'step' to it I'd change the tyre as it'll make things easier for you.

Don't worry about this, people talk bks a lot. What you can't do it lob a new pair on and just crack the throttle open as it'll have you on the floor. Just take it easy and you'll be fine but the comparison with riding on ice is a *massive* exaggeration.

I have to say that I think you're worrying about this too much. If there's a step in the tyre and you feel a resistance to leaning over go buy a new rear. All tyres square off to a degree unless you're a riding god or track all the time, don't worry about it too much, post a picture if you're unsure. Just relax and find your way at your own speed.

Thanks, that's helped a lot. 2 new tyres it is.
