IT IS NOT SAFE TO EAT THEM. It is caused by the potato being exposed to the sun. In future keep the potatoes covered with soil to stop this happening.

15-20weeks from planting. Read up on the internet. HOW TO GROW POTATOES

I have potatoes growing in last years patch, from some left behind and unharvested. They look healthy, will they give a reasonable crop or should I pull them and put new seed potatoes in?

Preferable to plant something different each year in the same bed. Let some grow and plant some new ones and compare what they produce. Gardening is about trying things.

how much water does potatoes need every week, month or year?

A good watering 2-3 times a week. Watering would depend on climate zone - how hot or cold the weather is, a cloudy or sunny day, small or large plants. Small plants small watering more often, large plants longer watering less often. Small plants only have short root system - soil dries out. A 4m row of small plants may only require a minute or two whereas large plants may require 3-5 mins.

Can I re use soil where potato crops have failed due to poor fertiliser and not using seed potatoes? Im concerned about diseases/fungus. Thanks

If they failed then you may have disease/fungus. Have good rich soil before planting and give a good watering twice a week when they are established.

I would like to endorse the comments above regarding the use of tyres to grow Potatoes or in fact use to grow any any food. The rubber compounds in both the carcase and tread contain significant numbers of nasties. Tyres are designed to perform at high speed under quite arduous conditions, absolutely not designed as end of life food growing receptacles! They contain many potential hazards/chemicals, far too many to fully list. I will list just a couple,so that fellow readers who do not have my background can appreciate better what they are dealing with. Firstly the reinforcing Carbon Blacks utilized in the rubber compounds, contain significant amounts of Organo-Nitrogen compounds, blacks of this type are banned for use with any "Potable Water" applications! the reason being these compounds are considered as being high risk carciogens. There are special Blacks made specifically for food contact applications, rubber reinforcing blacks are definitely not suitable. Processing aids, The rubber in the tyres must be made to be strong/resilient/heat resistant; specially designed chemical compounds are encorporated into the rubber compounds to achieve this. The chemical compounds used present problems in many directions, firstly they are not ( dont need to be) pure compounds they contain debris from the chemical synthesis processes used to make them; these same compounds also decompose both during Vulcanization and during the life of the tyre. The Organo-Chemical families many of these compounds belong to include compounds that are considered hazardous and not suitable for food contact. The possibility of side chemical reactions between both the impurities and the debris from the degradation, resulting in compounds that could present significant hazards is real. Are tyres dangerous? yes! when attached to cars driven by idiots and when used as receptacles to grow food; otherwise no!
