Thread: Causes of Punctures

Maybe the reason for an increase in nail and screw type punctures is that there are more of them around now, than a few years back?

Or maybe you arre driving on areas where they are more likely to occur?

Perhaps the older harder rubber resists the sharp objects better than newer sticky rubber. New tyres are designed for grip much more so than years ago and are often thinner. You should see how much crap hot sticky slicks pick up when you leave the race track.

I was wondering if less pressure would possibly have saved the day?

I am not keen to repeat this $450 experience

So, suggested offroad pressure to try to save punctures????

20psi is a good launching point.

The only punctures I've had off-road were caused by broken wheel rims!!! I'll also add that most punctures I've seen were caused by incorrect tyre pressures (too low), especially when driving on dirt.

FWIW - The only time I drop my tyre pressure is when I'm on very soft sand. All other times I'm running 45psi front & 60 psi rear (when loaded).

So, the moral of the story... If you want to avoid punctures when out in the bush, don't air down.

PS - I have had punctures on-road and they have all been in different sets of Goodyear Wranglers. I've never purchased them out of choice as they have come supplied with cars that I've bought and in all cases they were part worn. In all cases, the inner wall of the tyre had given up... Then on further inspection I noticed other tyres doing the same thing. IMO - Goodyear Wranglers are !!!
