New series Landcruiser and tyre choices?

Hi

Anyone purchased the "new" series landcruiser and experienced difficulty finding repalcement tyres - for the Dunlop GrandTreks. Tried buying some BFG AT's but apparently they don't make them to the LC's new compliance spec's. Load rating has been increased on new LC to 115 from 112. My dealer said he would sell them to me but refused to put them on - "illegal". Two choices - Toyo AT's or Coopers. My dealer (very reputable and reliable) is recommending the Toyo's - given the 80/20 (road/offroaddriving) I will be doing. Anyone purchased Toyo's before.

Thanks
