not sure if this is the right section. I've had my bike for about 6 weeks and I've had 5 punctures already. 4 in the back 1 in the front. my tyres are inflated to around 45-50 psi. most of my riding is done on road with a bit of off-road. I try to be careful not to ride over foreign objects etc. Is there anything I can do to prevent punctures occuring so often?
thanks.
thanks.

Also its worth checking inside the tyre for anything that might be left behind from the last puncture.
cheers

exactly what i was gonna say. just grab the tyre and wiggle it around to make sure the tube is in the tyre.
If you ride thorny tracks, flinty hills, or through brambles then you'll be experiencing a lot of punctures. I find that the late autumn is the worst time, when I've suffered five punctures in a single ride
To minimise your punctures:
Make sure you're running decent rubber. Stock tyres on cheaper bikes isn't nearly as resilient at decent rubber from a top manufacturer. Use decent tubes from a well know manufacturer too.
Run higher tyre pressures. This will reduce the chance of snake-bite punctures (where the tube is caught between the rim and the ground) and will fend off more of the pointy things laying around on the ground. The 50psi you're already running should be plenty though.
When you do puncture, make sure that you thoroughly check the inside of the tyre carcass for anything protruding. Many a time I've stopped to fix a puncture only to find that I have two (or more).
You could try the Slime or similar filled tubes or sealing-strips, which act like a tubeless tyre (see below) but without the hassle. Some folk have great success with them, but I've never rated them.
The ultimate puncture-proofing method is to go tubeless though! You can purchase kits for around £40 which replace the tube with a latex (or synthetic) liquid which seals holes as they appear. Since I went tubeless I have yet to have a puncture
This should give a good indication as to what the cause is, either damaged rim tape or something coming through the tyre?

If your still getting punctures after you've checked the rim tape and tyre for forign objects, next thing will be getting a better tyre/tube combo.
Bonty Mud-X's - completely bullet-proof (but they're tubeless with sealant!) 8)
Maxxis Minion - almost puncture-proof! (But weigh a ton) :shock:
Pana Fire - almost puncture-free
Pana Cinder - relatively puncture resistant :?
Kenda - punctures at the merest sign of something pointy :evil:
I think mine may well be the OEM version as I got them cheap off ebay
Still not had a puncture with them no matter what version they are though!
The JustRidingAlong site and Stans site also list the types/makes of tyre which make the best tubeless conversion. IIRC Bonty tyres tend to be tubeless-ready.
If you are certain that the rim doesn't have any sharp dents or burrs and that the rim tape is on correctly and there are no sharp edges on the spoke holes, then it's most likely to be caused by the tyre.
Do you have a hole in the tyre? You should not need to run slim tubes.
The Tubeless kits would be the answer if it's always thorns you are picking up, but it sounds to me that there is something wrong with your setup and my guess would be that you need to inspect the tyre closer.
My mate runs tubeless and just changed his tyres over from winter specific to 'less' winter specific tyres for XC riding. He checked the old tyres and found a dozen or so thorns in each one. They had pierced the tyre, sealant had sealed around each thorn then the rest of thorn had been worn down outside the tyre so you wouldn't notice if you had a thorn or not!
That tubeless thing seems like quite a good solution to punctures/flats!

I've read this with interest. Rear wheel puncture occur's at about 5oc from the valave stem on the rim tape side. Examined the tyre, nothing evident. Rim tape has some very small specks of metal that can only be seen by angling the rim to get it to reflect. So I'm gonna gently emery cloth aound the spoke apertures in that region of the rim. Re inspect and fit a new tube.
Interestingly, it always seems to puncture when I'm pushing on a bit, especially on a wooden or gravel surface. Had this bike 3 months, been mtb ing, for 23 years, yet had more punctures in the last 3 months, tha the 23 years.
let us know how you get on projectsome
I had them replace the censored tape on rear wheel after a week and put a new tube on for free.
I'm still getting punctures though!
Am I being too harsh with the bike?
It always seems to pinch the tube but I don't hit the rim cos I'm running at about 50psi. I go over a lot of curbs on my route to work.
How tough should I expect it to be? I'm gonna try and get halfords to give me a new bike.
take both tyres off and chek the rim tape, square it up and then get some electrical tape and go round the rim over the original rim tape and pop a key or something through the whole in the rim to allow the valve to come thorugh...its worked for me.
hope that helps
Took it back to halfords - checked the tyre - it had pinched again on the rim. Tape looked ok but it still pinched.
Left it with them - they swapped the wheels and tyres out from another 07 fury and put 60psi in each tyre.
Took the bike to work on Tuesday, cycling back - front goes flat.
Looked at the tyre - pinched on the inside again.
Took it back to halfords again, basically demanded a different bike. I'm not sticking with those 07 Fury rims at all no matter what's been done it goes flat. I'm not rough with the bike and I'm not hugely heavy.
Halfords have said I can have an 08 Fury instead which I know has different rims.
I think I'll have an 18" frame this time as well - even though I'm 6'2" I prefer a shorter reach than the 20" frame.
Anyway, to be fair, Halfords have been very good about everything. I doubt an LBS would have given me a new bike - they simply wouldn't be able to afford to.
We'll see how we get on with the 08 Fury....
I think the Sun Rims are far better.
Much happier on the 18" Frame and it looks nicer as well.
