Did you end up going ahead with these? Which ones did you get?
The only options i see are p-rated or c-rated, so i wasn't sure if they were high enough capacity.
I went through this earlier this year, deciding to replace my 1 year old CastleRock (225/75 15 E rated) tires. I discovered there are 2 LT E rated options in 235/75 15, the closest size. Those options are the Falken WildPeak ATW3 and a Nokian Rotiva (made in Finland). I ended up going with the Nokians, had them balanced and they've been great for a few thousand miles now. The sizing difference was minimal and they fit on my TT with no modification or issue.
