305 tyres on 110

Advise needed please......Just been offered some 305 mud terrain tyres for a 110 TD5. Will be great for v muddy farm, though I also need as tight as possible steering lock for transporting beasts to local slaughter house! Is there anyway I can fit the 305's without ending up with rubbish steering lock - i.e. spacers????
Cheers,

:doh:

got 315s on my disco on offset rims no probs with loss of steering lock

offset rims is what you need my farming friend
