Yeah I know retreads aren't as good as new tyres, but the 225 75 16's on my pickup look a bit weedy.

Seen some NEW 285 - 295's that are about £180 EACH !

On the other hand, a 275 74 16 retread can be got for £58..

What do you lot think about retreads, and 400ft/lbs of torque? will it rip them apart? would it be safe? (I'm not going to exceed 90mph very often!)

By the way, I don't mind the profiles going up/down whatever. Just as long as the tyre width increases - the brakes are FIERCE, and need the additional rubber contact patch.

cheers, Carl.

I've never trusted retreads esp with performance requirements (like high power or breaking required). A friend of mine in the business of tyres actually refuses to sell them becuase of incidents that he has seen.

I saw a re-tread that the tread patten came apart at 80mph on a hot day, the guy himself. And they were only on a 190 Merc.

There's not much that keeps you on the road, the adverage footprint of a car is about the size of an A4 sheet of paper - I'd never trust re-treads.

The only time I ever considered remoulds was when I did road rallies in the mid 80's (Colway). For everyday use; NO WAY!

Don't do it. If you are going to travel at over fifty mph with remoulds, you are risking them falling apart.
Certainly not wgat you want at anywhere near 90. Quite frankly I can't understand how people are allowed to buy remoulds for cars or bikes at all. HGVs are a different matter though.

When my brother had a series II Landie with 18" wheels (better than it sounds, believe me), he had the same kind of quotes for tyres. He bought four brand new big name tyres at the Land Rover show (LRO-magazine organised IIRC) for the price of *one* at dealer prices.

Have you considered stealing tyres off Vitaras?

Carl - if you really don't want to empty your pockets to sort your rubber out, why not consider part-worn from Germany rather than remoulds?

Probably cheap and safer (provided they're undamaged tyres).

You can get Hankook 275/70/16H for under £80 at mytyres.net (inc postage but + fitting obviously) and Yoko's for around £90. Don't see much point in fitting remoulds to save £15 a wheel.

That little throwaway is going to require explanation! Why exactly? Surely HGV's give tyres a harder time than any of us could ever hope to do, no matter how hard we think we drive. And the potential consequences of tyre failure on an HGV at speed - well the M6 is often witness to that. So what did you mean exactly?

IIRC, Truck & bus tyres are designed to be re-grooved.

Aircraft tyres are remoulded as well.

Of course apart from concord.

Unless you run a french airline and fancy some cost savings, then you still don't use remoulds, you just dont change the tyres untill their down to the cords.
The rest is sad history.
(of course the airport authorities don't have to keep the operating surface FOD free either)

I knew that, I was just wondering if that was what MadCop meant . We'll never know now!

MadCop, was talking about remoulds, which are totally different from re-grooving. We have all seen the remnants of HGV remoulds on the hard shoulder.

Whilst this is generally true, the sideways cornering load on aircraft tyres is typically rather low (at least after the initial touchdown) Also the undercarriage is designed with redundancy in mind, so the occasional blowouts are generally not even noticed by the passengers.

Hrm. What about crosswinds...? The huge sideloadings are then taken by the tyres and mainwheels. IIRC, the 747 was designed to withstand landing with up to 45deg of yaw on...! I'd expect a fair load there with all that weight and an over the fence speed on around 170mph...

For my 2ps worth, I wouldn't trust a remould on a radio control car let alone a real one...

Intrigued, can you give further explanation??

1. Because of the speeds that they are not capable of reaching. Most will not go above 80 mph.

2. Because they are large tyres and have a far greater surface area to adhere the new rubber to. (Someone will no doubt give a technical reason why this is not the case) and the revolution of the tyre is less, relative to a smaller tyre at the same speed (a car wheel travelling at 60mph revolves a lot faster than an HGV wheel at 60mph)

3. Because generally they have lots more wheels than cars and a failure on one is unlikely to result in a loss of control for that vehicle (unless it is a front wheel, which they shouldn't be used on)
I accept that large pieces of tread in the carriageway are not good news for other vehicles travelling at speed BUT if you are concentrating properly and driving at a reasonable distance behind the vehicle in front, you should be able to plan around them.

I have never hit tyre debris despite spending a large amount of my driving at well in excess of the permitted limits.

The other alternative of course for HGVs is to have the tyre treads re-cut which is slightly less of a hazard than a re-mould.

I personally would never put a re-mould or part worn tyre on any vehicle that I owned as you cannot know of its previous history and whether there is a serious floor or damage to the structure of the tyre that you cannot see, within the new or existing rubber.

That is just my opinion.

Remoulds are made to the same standards as any other tyre and you can get them in all the high speed rating as you can with new tyres. There's an awful lot of b*llocks talked about remoulds and most of it stems from the bad old days when there was much less control over quality and standards. I bought a nissan 200sx a while ago which had after market wheels on that the guy had presumably bought with a set of 225 z-rated remoulds on. I had this car up to speeds of over 130mph and happily hung the back out around corners and
the tyres never caused any problems at all.

The only reason I changed them and wouldn't buy them again is that ultimately they didn't offer very much in the way of grip but I had absolutely no doubts over their structural integrity.
