Advice on rims/tires needed!!

Hi,
We just bought a 2020 Tacoma 4x4 SR5 used, as we are exporting it out of the US to our island home and we are unable to export a brand new Tacoma (which we could spec as we wanted) for various annoying reasons. This is to replace my husbands beloved 2003 Tacoma which he has driven into the ground at this point.
The new truck is in pristine condition and ticks all the boxes, however, the tires just look wrong. We are going to replace them before exporting… but don’t really know what to put on there to make it look more… proportional?
Why do these tires look so small? There are 245/75/16 on there now.
What do we replace them with?? Help.

 

265/70r16 or 265/75r16 is where you can go without a lift usually. That would help fill the fenders up.

 

DCLB looks great with 265-75-16!

 

The 245 is the standard size on the SR5. The off-road upsizes to 265/70R16.
