Partworn Tyre Business. How to find punctures?

RBKATU

Hi,

I am in the tyre business and sell new and part worn tyres. I sell part worn tyres that are pressure tested beforehand by our supplier but there will always be a small few that have punctures and bulges.

I will be buying a tyres pressure tester(Picture below) so we can check the tyres thoroughly before sale to avoid any problems. This is a machine that pumps up the tyre so one can see if there are any bulges or punctures/air leaks

Ask the tester can't really detect small pin hole like punctures, my question is would anyone know a way to be able to find these tiny punctures. They could be found with spraying water on each tyre that is been checked but this would be very time consuming.

Anybody have any ideas.?

Thanks for your time.

Large barrel of water is the most simple and thorough way. Messy but guaranteed to locate a puncture or leak.

The pressure tester will show you if you leave the tyre on long enough ( the gauge if accurate will loose pressure over a short while. Especially at the pressure you'll be testing at which should open a pinhole up a bit )

Otherwise a spray bottle with soapy water sprayed around the tyre is excellent for finding leaks. Or a water bath will do the trick.

Could you submerge that contraption in a large fish tank?

Proper certified part worn tyres are x-rayed as well as pressure tested.

In the UK certified part worn tyres must have PART WORN stamped into the sidewall but we don't have that rule, or any real regulation for that matter, here.

Just spray soapy water on as you check it for bulges, kill two birds with the one check

Thanks for the reply. I know this way is accurate when testing a tyre on a wheel but wouldn't be possible on the pressure tester machine.

Thanks for the reply, I suppose that would be a fair point with the gauge. I'll keep it in my mind.

Thanks for the reply. Yes I have heard of x-rayed tyres which is basically what I need. Maybe I will just have to try and locate some from the UK.

Thanks for the reply. Yes that would work fine. Would just be a bit time consuming when testing a few hundred tyres.

Not sure how many of these tires you sell daily, but make sure to have 2 sets of each size you sell properly tested, and update stock as required.
With the rest - do spot checks, check random tires to see how many are dodgy, and get back to supplier with results. You are totally right not to trust your supplier and do your checks, as this is your reputation at stake.
I know it is not exactly what you asked, just my two cents....

Thanks for the reply Wonski. Yes we try and thoroughly check each tyre before sale. I'm just wondering where could an x-ray machine be located to check tyres. Would there be one that can be bought without breaking the bank.?

i am in the partworn trade .. it is impossible to pressure test every tyre.. i wholesale partworns and take in about 5000 tyres every month.. if i was to pressure test them all i be busy lol

I presume you could spin a tyre on that tester?
If so all you need is to weld on a little platform and stick a bucket on there thats deep enough to cover the tread, if the hole is in the sidewall then the tyre is junk anyway.

Lovely reassurance for those buying part worns. Much safer to buy new tyres, especially with cowboys who don't/can't/won't test the tyres properly.

i wholesale new and partworn if it was my choice i rather sell new all the time but you have to supply what the customer wants .. AS for cowboys you talk about most partworn tyres are ok i have been supplying these for quite some time now and never had any problems ..

What he meant is (I think) he can't test all the tyres properly when buying them in bulk. Whoever is putting the tyres on your car can test them easily.
This isn't something the end-user has to worry about at all.

yes that is right people buy partworn tyres they know the tyres are not new .. i have also sold new tyres that have blown out ...so new tyres can be faulty as well ..all am saying if you dont want take a chance with partworns then just buy new tyres..
