Thanks Federic, I appreciate your advice. My off road trips are equally sand, wadis and mountains and, whilst I’m aware that the Duelers are OK in the sand, I’m not sure how hard wearing they will be over sharp rocks. I am thinking that the BFG’s might be a better alternative in this environment. I have been thinking that the 275x65R20 might be a possibility, but I have read various conflicting opinions about them rubbing on full lock. Once you start modifying the stock vehicles then all sorts of issues start to arise and we end up spending far more than we had originally planned for. I have looked into 18” rims, 2” lifts etc etc but my budget was spiraling out of control. Therefore I have decided to stay with stock everything for now but hopefully having a slightly higher spec tyre. Thanks again for your input, much appreciated.
