Averaging a puncture a ride! advice needed...

jones1328

Hi All,

You've probably read the topic subject so know where I'm going with this post. Basically I seem to be getting a puncture every time I go out on my bike.

I'm running a set of Michelin Pro Race 3 tyres on the Shimano WHR500 Wheelset but seem to have a nasty habit of getting 'pinch punctures' Now, you'd think I'd be having to hit potholes/cracks in the road fairly heavily but it seems the very slightest chink in the road results in a 'pinch puncture' deflating one (or both) inner tube(s).

Does anyone have any advice/recommendations as to ways to reduce (or eliminate) this regular and frustrating occurance? I've tried the good ol' puncture repair kits and even the 'pre glued' patches (Slimes 'Scabs') but both seem to blow out after a short period of time.

I've now tended to just replace the punctured inner tube with brand new ones but at this rate its going to cost me a small fortune!

Does anyone recommended going 'tubeless'? and if so, what are the best tubeless products out there?

Thanks in advance.

more PSI

How much air are you putting in, could be as simple as upping the psi.

check the rim tape too.

I have had a set of Pro race 3`s for a couple of years now and found them to be very good. If you are punturing regularly as previously suggested check tyre pressure I keep mine at 100 psi, but also check rim tape and inner side of tyre. Hope it gets better, I like my pro race 3`s.

What size tyres are you running? If I run 23c tyres I have them about 110psi for my weight. For poor road surfaces I use a 28 on the front and 25 on the back on a pair of cheap touring wheels, they don't need so much pressure and are more comfortable on rougher roads/cycle tracks. Also try a different brand of inner tube, some are a bit thicker/tougher than others.

CTC Recommended pressures link



"To use this chart, add the weight of rider, cycle and luggage and estimate the loading on each wheel. Up to 70% of the weight is carried by the rear tyre of a normal bicycle, but the ratio may be nearer 50:50 for a tandem, especially when the front rider is the heavier of the pair.

Note that this chart gives the minimum pressure for smooth roads. You should never let your tyres be lower than this and usually aim to pump them harder. Remember that narrow tyres lose pressure quite rapidly and should be ‘topped up’ every few days. Most people will want to use a higher pressure to minimise rolling resistance (although that reduces comfort) and to avoid tyre or rim damage on rougher surfaces. To allow for this add a safety factor to the weight of about 25% for poor roads and gravel tracks, or up to 50% for real rough-stuff."

Are you cycling the same route every day? I one went through a phase of puncuting every day on my commute for 10 days. It was only after changing my tubes and eventually tyres I realised it was a particular spot on the road that was causing a puncture every day

I tend to do a similar route every week night but get punctures in different areas (quite frustrating!)

Thanks to everyone for their advice, will pick a proper track pump up tomorrow to make sure I'm inflating to the proper/recommended PSI.

Check that the puncts arent occuring at the same spot on the innertubes, could be some grit, thorn etc in the tyre.

have a look here from about 3:30 in.
