255/85? We got the RV 105 in Australia which came with factory 235/85R16 and 6.5 wide steel wheels instead of the much wider 275/70R16 and 8.0 wide GXL spec
The Toyo AT3 recently came out in a 225/95R16. Likely a longer lasting option than the Dunlops.

How did you go with this?
Noticed there’s another size available now for skinny 33s being 235/80R18.
