I have an air leak btween the trye and the alloy rim on my defender 90 there is no damage to ether is the any way this can be sorted without taking it to a garage or is there any stuff you can buy to seal the leak.
if there is anything you know please let me know thank you
Not really, but a decent tyre place should be able to take the effected side off the rim, rub it down with some wet and dry, then re-bead it without needing a re-balance. Should only cost avbout £10 but worth getting it done.
