Large lorrys can use retreads can they not.

When I worked in the tyre industry, many moons ago you could get 2 types of remoulds....Retreads where a band of rubber with the tread on was stuck to the tyre and remoulds, where the whole tyre was worked on and put back into a mold....Hence retread and remould.........

No, with only 4 points of contact on the road, I'd like to know I've got new fresh rubber supporting me and my family.

I used to use Colway remoulds on my Austin mini back in 1987 , no problems with them but it wasn't exactly a performance car , I'm sure they were around £9 each back then....10" wheels tho!!

No way - wouldn't trust them.

I had an Audi that had remoulds on when I bought it - you could see the cracks appearing where the remould was separating all the way around.

i just remember going to spain when i was kid aand the hard shoulder on the motorway was always covered with bits of remold treads

I have used them in the past with no real issues. These days manufacturing processes are far better, and you can even get high performance rated remould rubber. Would I use them now, yes without question as they help save the planet, but the price needs to come down. That said I would only use them on a non performance car.

Virtually every articulated lorry does - if they're good enough for carrying 44 tons they'll carry your little Skoda about

Nope. No they don't. Truck tyres can be recut. Not the same, and I think you are getting confused. Look around next time you see some trucks parked somewhere. Remoulds are not on nearly all trucks, merely a very few. Some retreads are often used, but not usually on 44 tonners.

Show me a HGV on scrap\quarry work not using remoulds.

Edit: Having worked in haulage for 3 years in my younger days I don't need to go find some parked lorries to look at - I'm not a spotter!

Interesting thread! I'd never (and nor have I ever) use them because of my perception of their safety. It could well be unfounded, but there are only 4 handprint sized contact patches between my car and the road and it's not something I'd want to try

This could go on for ever. 3 years eh? You have seen and done it all. Scrap and Quarry work? Thats not quite all trucks is it. Find me a decent looking scrap/quarry/tipper/bulker truck.

You are misleading the people on here in to thinking that remoulds are safe because you think they are used on all/the mojority of trucks. I put it to you that is utter nonsense.

I have done on my Moggie for many years with no problems but again its hardly high performance. They do seem to have improved quality wise over the years and are probably ok for normal road use as long as you use reputable make.

Intersetingly (to me anyway :P ) Colway's site claims that:

-18 per cent of cars on British roads use re-cycled tyres.

- 50 per cent of trucks on British roads use re-cycled tyres.

- 98 per cent of the worlds airlines use retread tyres.

... so on that basis, are those that won't use them going to stop flying

Retread and remould are two different things, as has been mentioned.

IIRC a retread tyre is a tyre that is designed to have a new tread cut into the tyre. If you look on the side of HGV tyres you may see lines going around the tyre, these are the retread line, what happens is when the tread has worn down the tyre is taken off and a new tread cut into the carcass down to the line, up to a maximum of about 5 time, I believe aeroplanes use the same system. A remould is where what is left of the old tread is removed and a new tread effectively glued in place.

Bear in mind the following points. 1: A retread tyre is designed to have a new tread cut into the original carcass, a normal car tyre is not designed to have its original tread removed and a new one glued in place. 2: Both lorry and aeroplane tyres have a relatively simple tread pattern suitable for their use, in this case straight line, whereas cars generally have more complex tread patterns to take into account cornering.

When a new tyre is around £35 fitted for a 16" rim, or a part worn around £15 - £20, how cheep is a remould?

I wouldn't use them, no. Nor would I want to use 'cheap' tyres. They are your only contact with the road, and if they fail - you die. More than likely anyway.

A retread is a tyre which has had a band of rubber with a tread on it glued to an existing tyre, A remould tyre has gone Back into a Mold to cure the whole tyre...............New, Remould and retreads can have new tread cut into them...........I have done it!!

Well thank you all for your contribution

You've done me proud!

Plenty of points raised and opinions expressed that will be useful in my report.

Once again, many thanks

Modern cars (and new tyres) generally have way better performance (acceleration, cornering and braking) than back in the 1970s when remoulds were fairly common. In a recent test a 1970 Mini on modern rubber got within 5 feet of the Highway Code dry stopping distance on a wet road!

nope...and judging by the number of shredded lorry tyres on the A19 maybe they shouldnt use the buggers either!

I've heard it claimed that most of the shredded carcases are caused by under-inflation, rather than pure delamination. If that's true, perhaps these self-proclaimed "professional drivers" should just take their daily checks more seriously?

When a new tyre is around

I think people are getting confused here. AIUI retread and remould are synonyms. What you do with a truck tyre is buy new and run to the limit, cut a new tread into that (re-cut) and run back to the limit, remould it placing the original depth of rubber back on the carcase, run it back to the limit, then recut that and run it back to the limit, before disposing of the carcase.

Ok, so I got it slightly wrong.

I did say if I recall correctly (which I obviously didn't) but I was trying to remember my automotive course from back about 10 years ago (has it been that long! :eek: )

No way.

As someone mentioned earlier, four little hand sized pathes of rubber hold my life, and that of my passengers and potentially other road users/pedestrians.

Cheap tyres? Last time I checked mine, even with discounts, for a "known brand" I was looking at

Gwilo, you do realise that aircraft tyres have to accelerate from rest to maybe 150mph in about a second every time the plane lands?
