Thanks for the replies.
The comments I made on the BFG were based on a Tyrepower dealer who had found that the tyres were difficult to balance and once they were balanced the balance change requiring rebalancing (I think that makes sense
)
The biggest problem that I face with the KJ is the tyre size. According to sources in the US, the largest tyre that can be fitted without rubbing is a 245/70/16 (BFG AT 29.6") which unfortunately is a size that the S/T's are not available in. They do make a P255/70/16 (not LT) which is just on 30"OD. CJBRAD ran with 245/75/16 (30.6") for awhile with fairly minimal rubbing.
Anybody know of anyone running this size tyre or has any opinion on whether it would fit?? (I'm prepared to get the heat gun out but not the grinder)
