Tyre carcasses - why

[Willhire89]

I have travelled the A14 several times this week and it is littered (no pun!) with HGV tyre carcasses - one on average every mile each way.

They have probably built up over a while but what causes all these failures

Poor quality tyres used t save money

Retreading - does that still happen?

Overloading

Other?

Tyres are regularly retreaded, its cheap and mostly used on trailer tyres. You'll not usually find them on drive axles.

They blow from defects, over inflation, damage etc etc, can be anything. The truck can stop a mile or so down the road after a tyre has blown so not much chance of the driver collecting it. The council/Highways should collect them but rarely do

Mostly from re treads on trailers , the main cause is low pressure, so the tyre flexes causing heat build up ending in failure of the bond between the old tyre carcus and the new tread band.

This! Low pressure causing heat failures on otherwise sound tyres. Any tyre will fail in this circumstance.
