I had a lengthy nerd out, but deleted in favor of a simpler response. No, I was ignorant to you having the +45mm offset TRD wheel upgrade not offered when I bought mine. I can long form the math here, but it boils down to mine being a 285 on +47.5 offset w/ ~ 13mm of poke. Converted for a 265 on +45mm and youβd be looking at ~ 5.5mm of poke measured to the lower lip of the arch top of your fender.
I agree with your concern and will be likely sourcing some LC trim fenders for mine. A 255 will produce only 0.5mm of poke for you, which is nothing.
