Hi maljb and welcome to the forums
Anything I need to be aware of?
There has been some discussion re. mpg.
Personally I am happy with mine so far [ 34 local and 27 towing ]
others have reported much lower results.
Also you will probably find that the kind people at Vauxhall have provided you with an inflation kit if you are unlucky enough to get a puncture.
If this is the case - and you do get a puncture then be aware that you will need to replace the tyre when you take it in for repair.
Also - if the puncture is in the side wall the kit is of no use.
I, and others here, have elected to buy a full size steel rim and put a suitable tyre on that. Peace of mind.
