which is the best spec in 205/65R15 - Innova tyres
Falken Azenis PT722 would be a good tyre to begin with for your Innova. It offers good traction and a comfortable ride quality. In case you want something better you can choose out of Yokohama C- Drive or Bridgestone Turanza AR20.
Turanza offers longer tyre life as compared to Yokohama C Drive.
They both are pretty good tyres, you can't go wrong with either one of them.
Yokohama Geolandar A/T-S would be recommended for unpaved ,rough and muddy roads.

Best A/T tyre for mahindra thar?
I would suggest that you go for Yokohama Geolandar A/T-S tyre. It is a very capable all terrain tyre and is quite durable to cuts and abrasions. And widely spaced lugs would offer adequate traction.
Another model that you can look at MRF Wanderer O/R. This is more if an outright off-road tyre and hence would offer superb grip off-the road.
