Poll , Front or Rear tyres get more PF visits?

[cyberknight]

Just a bit of fun

When i get the occasional p**cture i always get it on the rear tyre so i am glad i have QR and a pair of rubber gloves.

Where ,if you get a visit from the PF do you generally get one?

Law of averages.

Law of averages.

It might be every one i have had in the last 2 years + have been on the rear

M+ = 0 rear 0 front

Secteur since new slightly more front than rear I'd say,maybe 4 front 2 rear.

Most of your weight is on the rear tyre. hence most people will get them on the rear. You will get them on the front if the tyre is nearly worn away and you don't pump it up.

Law of averages....

.... does not apply here.

As Gaz says, the rear takes most the weight and so will be the most vulnerable.

I voted twice as I used to get them in the rear (Fnaar) until I put on M+

Law of averages.

As any mathematician will tell you - doesn't exist!

Don't know about M+, I haven't had a puncture on any wheel fitted with an M, without the +.

I have had 3 in the past 2 years all in the front, one on the OEM tyres on my Dawes Horizon, one on the OEM knobblies on the Ridgeback MX4, and one on a Kenda Kwest fitted to the Ridgeback. All 3 from hawthorn thorns on the canal towpath.

Lord, no idea. I'll tempt fate here and say I don't get that many (not M+ either, Conti 4 Seasons or Gatorskins) BUT I'd guess I've had more rear than front.... not by many though.

Obviously the front tyre gets first go at all the cr*p and there is more likely to puncture (armchair theory)

The counter theory is that thorns, nails, etc. lie flat on the ground until the front flips them upright, just in time for the rear to impale itself on them.

Also, snakebite punctures are more common on the rear because most of the weight is on the rear tyre.

Also, the rear tyre has a larger contact patch with the ground, so is more likely to encounter more debris.

Also, the rear tyre tread sees more load which leads to more wear so is thinner.

Also, the rear tyre has chain lube washing over it, weakening the rubber.

The bike has two tyres.

Thorns, nails, spikes and broken glass that is seen by the rider is avoided. The sharp objects that are not seen could find their way into either tyre.

The rear tyre bears 60% of the vehicle's weight. Pump the rear to 120 psi and the front to 80 psi and they both have the same contact area.

Only an idiot cyclist would allow chain lube to get on the tyre. What do you think local free newspapers are for? reading?

Most people keep both tyres at the same pressure, or only slightly lower in the front, not nearly low enough to "equalize" contact patch size. I ride 85 rear/60 front, after I actually weighed the front & rear axle weights, however no-one else I know ever does that.

Rain washes the lube off the chain/cassette as the bike is being ridden, hard to ride a bike with newspapers on the back wheel.

Ectcherly, there's enough oil and stuff on the road to dissolve both front and rear tyres.. Never mind the chain lube.

I've never weighed my front & rear axles. Life is too short.
