18 in rim for trail??? Why

I am looking for a good condition 426, when I do get one I am going to use it for desert an occasionally trail, but why put a 18 in. rim on??? what can that help???

Thanks, please ignore the s/n. heh :D:)

it could help you get fewer pinch flats and better traction in loose terrain due to larger air volume (means you can safely run lower pressures).

a big 19" tire also works well. i like the maxxis IT 19 x 120.


thank you, now I know.

The larger sidewalls also give you more flex and better bite when running rocky terrain. The overall diameter of the YZ's 19" and the WR's 18" are the same.
