i used one on standard rims on insa turbo sahara's and as previous threaders said virtually unstoppable (they are a spanish remould) although i didn't use it for long runs they were relatively cheap and long lived, i do a lot of off road training for various organisations in anything from unimogs to the normal range of landies/L200 etc, the jimny excels where the heavier wagons break through to a lack of tractive surface, as others say it gets a bit cosy with a large buck/stag residing inside with you.
