I know I'm not Dtt255, but it does fit...I had those rubbers on the stock rims, and no problems getting it under there, same as stock.
You can fit up to a 33" x 12.5" in the spare wheel spot.
Nitto Terra Grapplers make a AT with the exact same dimensions as the stock LC200 tire...great for snow.
I fitted 17" TRD wheels with BFG Ats, am so happy.
All Tundra wheels fit on the LC.
