Tyre Re-threading Legal ?

[Blueblack]

Hi all,

 

Just saw a tyre shop in Serangoon Rd working to rethread an old tyre using simple tool using heat to cut the thread. I know this was common donkey years ago but really surprise after all this years.

Is this still legal and is there any rules and regulation on this.

Can't imagine what happen when tyre exploded at 100km/hr.

What you have witness is regroving and not retreading, click here for more info

But such method is only applicable to heavy vehicle tyre, I assume? Normal car tyre maybe cannot?

Sometime Can See Some Pieces Torn off .....left over at the Expressway...

to me, legal or not is not really that impt here. I am wondering if safety is compromised... would anyone still want to get their tryes to do re-grooving? not for me.

Oic, acceptable method to extend truck tyre life, does it apply to small lorry and car as well ? what I saw is only a 17~18 inch tyre.

 

Also like one bro said we also see torn off tyre on the road. Kind of scary feeling imagine a truck tyre kapo and the tyre fly toward you... worst if truck come eeee toward you.

Regrooving is allowed by most truck and off road contruction tyre manufacturers.Regrooving is never been used on car tyres. All tyres including aircraft tyres can be retreaded - can be even better than the originals

well... my car is on 14" tyres so they are not expensive.. every 60000km i change 1 set cost 200++ - 300+ only.. so i dun see a need to rethread, maybe if i am onl 17-19", and each tyre cost $300+, then i may consider.. that's why i have not changed my rim size to 16 or 17", tyre cost between 14 and 17 is alot!

So long as it's a truck tyres - size does not matter as truck tyres are designed with more plys and therefore have much more carrying load capacity as compared to car tyres of the same size.

Retreading process is cumbersome as it involves many manufacturing stages - from collection of tyre casings to inspection & selection of casings, buffing the casings, application of rubber compound, final stage of curing the rubber compound/threads, final inspection and finally delviery to resellers.

Unsuitable casing, poor buffing standard/finish ,low quality rubber compound and even uneven heating curing process - any one of this process not properly handled can in turns product low quality rethreads.

Regroovable tyres are usually marked "regroovable" on the tyres. Nowadays only tyres for heavy vehicles are regroovable.
