Time for new tyres? Superglue?

[Mo1959]

Strangely the rear tyre seems more worn along the centre line than the front. As they've both covered exactly the same ground and the front one does the turning I would have expected the opposite if anything - and no I've not been pulling skids!

The rear carries more of the weight so usually wears a bit quicker.

No that's usual. The rear tyre takes most of the weight unless it's a TT bike and also provides the drive, effectively always pushing back along the road whenever you pedal. Some rotate tyres front to back, others swap, while I just mismatch

I super glued a hole on one of my gp4000s then the next morning decided to just swap the tyre as I had a new spare sitting , when I removed the old tyre the tube was super glued to it and burst open as I pulled them apart , lesson learned

Superglue for small nicks is another bit of bicycle folklore like letting tyres down to fly and x-raying carbon frames. It doesn't work.

Time to replace that tyre, it owes you nothing.

Thanks for the feedback everyone.
I don't think they're massively squared off, but it is definately noticable when looking along the centre of the tyre at eye level. I'll try the deflate and squeeze to see if I can ascertain how much rubber is there - I suspect a fair amount still judging by the depth of the rubber before it becomes canvas around the various nicks.

I use superglue to fill small nicks but once the count reaches two i bin the tyre.I emphasise small nicks If you can see the canvas forget it
Back in the day when tubs were popular you could get a product called Tread Stop I believe it was called.
L don't know if it or something similar is still available

Superglue sets too hard and can eventually be pushed into the tyre and cause more problems than it solves.
If you want to try patching small slits in the tyre look for Storm Sure rubber adhesive.

Superglueing tyres?! I have so much to learn....

Thanks everyone. Pair of Schwalbe Durano S bought and ready to go on. I'll give the glue and other patching options a swerve - not worth the risk for cycling at speed by the sounds of it.

If your new tyre has a cut and you're worried about the carcass failing, especially if you use latex inners, which will find the smallest weakness and pop through it, you can try patching the tyre from inside. I have and it will let you eke a few more miles out of the tyre.

Wouldnt superglue in a tyre cut be similar to a foreign object getting lodged in there? I would think that once the glue goes hard, it may also become sharp and embed itself further into the tyre.

I managed to gouge a nick, in the front Lugano, on the 'blue' Ribble this afternoon
(new pair, only put on about 100 miles ago)
It's not deep, & there was a lot of glass at one point, but it was annoying
Which reminds me, I'll have to check the rear tyre in the morning

Blimey my Conti 4000s II are much worse than that??

Are they as bad as the Schwalbe Blizzard (I think that was the model?) that were on my old commuter

Despite the appearance, I believe it showed just how puncture resistant they were!!
I only looked, after someone asked me if I'd ridden through red paint

Hi,

I'm currently eyeing up tyres for my road bike for next Spring. Was planning to put some on my Christmas list. But after another puncture at the weekend (that's 4 flats in the 4,000 miles I've done on them, 3 on the back tyre, 1 on the front so not all that bad for stock racey tyres?) I'm wondering if these tyres have about had it now.

Now I also have my winter bike (shod with Marathon Deluxe) I won't be using the road bike for more than another few hundred miles up until xmas, so maybe these will last me that long (and more?)

This is my first road bike so am not sure when to change really - in the past I would go by tread wear but that doesn't really apply to slicks. They do look a bit squared off in the middle, and have quite a few nicks in the rubber as pictured. My friend reckons you can bung these up with superglue to prevent nasties getting through - is this good advice or would it affect the safety/performance of the tyre?

Thanks, Andy

I have used super glue to repair small nicks .but that tyre looks well past it sell by date.

At one time you could get something called tired stop I used it on tubs

Depends if you want to replace them, what i mean is for me it would be a good excuse to buy some nice tyres but if youre a tight arse or want them to last wait until they go bang

I decided to try something else, having kept the bike in the basement overnight, to dry out any moisture in the cut, & used black silicone sealer
it should adhere, & deform as required

The tyres on my commuter have quite a lot of small cuts like those in the OP photos. As long as the cuts are fairly short, and do not penetrate the tyre threads, I just carry on riding. If the tyres are bulging badly around a cut it means the threads are damaged, so you should replace. These cuts can occur within weeks of fitting new tyres, so it seems terribly wasteful to keep buying new. If I replaced every time I had a few small cuts I'd be getting hundreds rather than thousands of miles out of each set of tyres.

I note that there is some squaring of the tyre profile in the photos, which indicates that a lot of rubber has worn away in the centre of the tread, so it may not be too long before threads start showing. To avoid the profile squaring you need to go round corners faster and only cycle on the most dangerous twisty mountain roads.
