So I know nothing about bike ?kit? / maintenance (I just commute on one) and I?m looking for a bit of advice... just paid to have a puncture fixed (back wheel). The shop advised me to replace the tyre. When I got home I realised that the new tyre looks quite a bit thinner than the front one (35 back, vs 42 front I think). I just assumed that they?d replace like for like, but now I have a fat tyre on front and a thin one at the back (it?s a hybrid). Is this an issue in terms of effecting how things work / the bike will handle or should I not worry about it? Thanks for your help.

Not an issue from a handling perspective but you may find the ride a little harder as the thinner tyre is very slightly less "bouncy". They should have replaced like-for-like, or at least asked you if it was ok not to. I suspect that they didn't have a 42 in stock as they are less common. You say that they fixed the puncture, hmm, if you were paying for a new tyre then I would have thought they would have given you a new tube as well. Not a major issue but a new tube is pretty cheap tbh and not much more than the cost of fixing the puncture I would have thought.

What brand of tyre did they fit on the back ? Others my have their view on the best brands but I have always fitted Schwalbe Marathon Plus tyres to my bike that I use for commuting into town daily, year round and I'm tempting fate but I cannot remember the last time I had a puncture.

They're about ?20 each.

Sorry, I wasn?t clear. I meant a new tube, they didn?t patch the existing one. The tyres are continental. I don?t think it?s a big issue just looks a bit weird having a fatter tyre at the front. I am surprised they didn?t mention that it would be a different size. Thanks for your response.

You might find it's a problem in the wet as 'slick' tyres have less grip than the fatter, knobbly ones, especially as the back wheel is more prone to slip as it carries more weight, thus why it usually wears down first. I use Balfes and they have always talked through what they are going to do and why...

Still a bit confused what actually they have done ? Personally i think its always best to have same tyres on both wheels .. and the fatter one if for some reason is thats the choice should be on back . My guess if it is a tyre is they gave you what they had in stock . Probably obvious thinner , slicker equals faster but harder ride and more prone to punctures

To be clear, they replaced the inner tube and the back tyre (following a puncture). The new tyre is thinner than the one it replaced and thinner than the tyre on the front wheel. I agree with you peckman - It would make more sense to have the fatter tyre on the back if they are to be different.

Odd comment. All to do with the surface area contact with the road and the level of resistance (adhesion). A function of tyre tread, tyre compound, tyre profile, pressure, temperature and the road surface including rain, snow and ice. Not simply size of tyre. Not sure if a patronising or inane comment helps.


Safety also depends on the way you ride, where you ride, and the behaviour of other road users.

Basically . This is it . There should be no reason why you should have different width tyres on any domestic bike and perhaps not unless you are going mud mountaing biking in wales . Any decent bike shop shop replace like for like. Who was the bike shop ?

Tbh you probably wont notice it if you are pootling around on a hybrid but certainly and self respecting bike shop should swap size for size .. discussion re tyre brands and compounds can go on and on but previous posts ys a good one .. something with some grip but nit slick !

OMG


What is the point of this thread?


Other than to inform people you had a different tyre fitted to your bicycle, not the same as previously on there, and although you know it isn?t quite right, it?s also not quite wrong enough to actually do anything about.


Other than sending them an email voicing your ?mild displeasure? and posting this on the EDF it?s all over now, yes?!

Being a bit pedantic, and slightly tangential but this:


"You might find it's a problem in the wet as 'slick' tyres have less grip than the fatter, knobbly ones, especially as the back wheel is more prone to slip as it carries more weight.."


is a common mistake. On a bike slick tyres grip better in the wet than knobbly ones, and carrying more weight also means more grip, not less. In both cases, more rubber in contact with the road = more grip. The only reason to have a tread if you're on a hard surface is to disperse water and avoid aquaplaning, but you'll struggle to go fast enough on a bike for that to be an issue. Knobbly tyres are only useful on soft/loose surfaces.

      Charter East Dulwich school

      By McMurphy · Posted

      interesting read.  We're thinking about the same things for our kids in primary school as well. One thing I don't understand about Charter ED is whether they stream / set kids based on ability.  I got the impression from an open evening that it is done a little as possible. All i could find on-line was this undated letter - https://www.chartereastdulwich.org.uk/_site/data/files/users/18/documents/9473A8A3547CCCD39DBC4A55CA1678DC.pdf?pid=167 For the most part, we believe in mixed ability teaching and do not stream in Year 7 or Year 8. The only exceptions to this are that we have a small nurture class for Maths. This is a provision for students who scored lower than 85 in their SATS exams and is designed to support them to acquire the skills to access the learning in mainstream class. We do not have nurture classes for any other subjects. We take a more streamed - though not a setted - approach in Maths and Science from Year 9 onwards. though unsure if this is still accurate reflection of policy, and unsure of difference between streaming and setting.

      Chicks and ducklings

      By Bumpkin · Posted

      My son’s primary school hatched duck eggs, probably under this scheme around 12 years ago.  We were all very upset to hear that 2 of the (5 year old) boys had knocked the incubator over & all eggs smashed.   feeling a lot less sad about that now!

      Cyclists taking over paths!!

      By malumbu · Posted

      What would I do about cyclists?  The failed Tory manfesto commitment to train all kids was an excellent proposal.  Public information campaigns aimed at all road users, rather than singling some out, to more considerately share the road, as TfL have done, is welcome too. As for crunching vehicles.  I'd extend this to illegal ebikes, illegal e-scoooters (I think some local authorities have done this with the latter) but before that I would (a) legislate that the delivery companies move away from zero hours contracts to permanent employees and take responsibility for their training, vehicles and behaviour on the road.   More expensive takeaways are a price worth paying for safer roads and proper terms and conditions (b) legislate to register all illegal e-bikes and scooters so that when they are found on the road the retailer takes a hit, and clamp down on any grey markets.  If you buy an e scooter say from Halfords this comes with a disclaimer that it can only be used on private land with the owner's permission.
