A bit about retreads / re moulds etc
A Monoform or Remould tyre is similar to a re tread in that its made using a second hand case ( that is a clean skin that has been used and the tread is worn out)
to make a re mould the case is placed into a mould and hot rubber is bonded to the sidewalls and the tread crown area. thats how they get their names on the sidewall. The rubber is moulded in place - thus its name.
Like any re manufactured tyre theyre only as good as the case and the process used to make them, there are also speed restrictions on them which may or may not have effects on your vehicle registration / insurance as your vehicle need to comply with ADR s and the tyre placard.
Having worked in the trye industry and managed a dozen or so retail tyre outlets , I would ONLY use re moulds as a last ditch effort where I cannot obtain new / second hand tyres at a good price
Balance and out of round can also be an issue, I have seen re moulds take 150grams or more of weight in an attempt to balance them.
In relation to Re treads.. it would most likely be because of price that you would purchase them, in which case my advice would be go and buy good second hand tyres rather than re treads leave the re treads to your mother in law.
Also in relation to re treads there are two processes to make them: Hot and cold caps. Hot caps - like Bandag caps are made in a similar fashion to re moulds where they are vulcanised at high temp / heat, cold caps are generally a cold process with the cap being vulcanised on at lower temp. (in general most of the retreads from trucks you seen on the road are cold caps......)
Having said all of this, retreads are what most trailers in aust are running, most drivers run cleanskins on steer and possibly drive of prime movers with the cases being used for caps on the trailer, coincidentally next time you are at the lights next to a semi have a look at the trailer tyres, where there is a tyre brand every letter ground off that is a time a tyre has been retreaded. so a Michelin tyre that reads "chelin" has been capped twice, to memory there is no maximum number of times a good case can be capped.
It is possible also to have your own cases re capped or remoulded, if I was going to step into the world of re moulds / re treads this is the way I would be going, a 750R16 case is a cost of about $15 on top of the retread price so a cap might cost $55 plus case plus tube (all caps must be fitted with tubes remoulnds may be fitted tubeless) $25, plus fitting and balance $10 and you are looking at $105 for a $55 tyre (or cap)
Hope this helps

Sure does help.... thanks.
I always wondered what that meant where letters were missing, now I know. :wink:
