Tyre Cracks

Also completely off topic but to save making a new thread and all that, i've got cracks on the wall of my tire close to the rim (on both sides and on both tires) is that something to be concerned about or just keep an eye on?

 

well... just went out in the rain to get a quick snap of them and turns out its the type of crack that disappears in the rain i'll have another look when its dry but im guessing now that its just a surface crack, if i see them again i'll get a pic and post it up. yeah i only noticed it because i was just over thoroughly checking the bike the other day

 

Yeah i was considering it but then i thought it would end up being thread after thread of me asking stuff haha when i can see the cracks hopefully in the dry i'll make a new thread for it

 

Cracks in tyres are a bad sign.
It means the rubber is no longer supple and flexing as it should under the force of being ridden about upon.
Are they old by any chance?
If they disappear in the rain then it might just be baked on dust from the amazing summer weather...


But to answer your question, no cracks aren't good and shouldn't be ignored on a car tyre let alone a bike one.

 

Dont think the tires are that old not sure if the dealer put new ones on when i got it, if not they have 7000ish miles on them if he did it will be around 5000 on them in which case that would only be last September so not old (in my eyes)

 

When made, not fitted. Check here:


Other things can cause loss of elasticity in the rubber, most often cleaning products and excessive heating / cooling - race tyres go off like eggs.

 

Okay ill also check that tomorrow thanks, i do clean her pretty regularly so that will prob have contributed.

I just looked on google to find something similar to mine this is the closest i could find, its like this but only i'd say hair line not as big as this from what i can remember

 

Has the bike sat for any length of time? That looks like a compression crack from the bike sitting for months not moving and the tyre pressure dropping. Rubber hardens and when inflated again, does that.

 

no its not been run flat that i know of, always kept the PSI up only dropped by like 3psi, i think it was in show room for a while though and i bought this last september and it was a 2008 with 2500miles on it, so not been used much to then being used everyday might be it

 

Listen to this one, he does know what he is talking about every once in awhile

Seriously, I echo what he said, don't risk it with tyres.

 

I'd certainly replace that soonest. As said heat, (inc sunlight) & age harden tyres. I've an original front on a 2010 bike which shows some cracking when warmed, thats nowhere near as bad as yours, which I'll be replacing asap.

 

I think you get where everyone is leaning too....cracks on your sidewall would give me the .... think about what happens it if it lets go mid fast sweeping corner...

I know its all money but you only have 2 wheels and 1 ass...

 

And there's already a crack in that!

 

Right got some pictures of my tires,

If you look sort of towards the rim there is a lip on the tire and to the right there is a small crack that follows it, its like that on and off around both tires

Another angle

Here is a general picture of how much tread is left, now im not sure i recon i have at least a few more months on this but there is a sort of chip in the tread dont know if thats another thing to worry about?

Also here is the date of manufacture ( i think... its the only thing with something like that on the tire) i think this would make it the first week of august in 2008 if im right

sorry for the amount of pictures just want to make sure that its nothing to worry about

 

Looks like the date indeed, although week 8 is more like the end of February by my count week number, not date.

So you there a tyre that's 4 years old, not really premium age. Those cracks are the beginnings of the rubber not stretching as it should.
The divit isn't anything to worry about, not only because the ture is knackered but on general.

How long it would normally last depends more on your weekly mileage than time also how you ride. Black Hornet has to carry spare tyres with him on ride outs, for example

If it were me, I'd have some new tyres on the shopping list sharpish.

 

aha yeah its February then
Okay its deffinatly on the shopping list then i decided long ago that im going to get some bridge stone BT-45's and instead of a 130 rear a 140
haha yeah i think i normally do around 80-100 miles a week, depends on the weather, if its bad i wont be taking the long route for sure

Thanks for the advice though just got to figure out how to get my tax rebate through now to pay for the tires
