Re: 5/6 drop?

245-40-20 F 1st choice
255-35-20 F other option
295-40-20 R

First choice fronts would be close to 27.7" tall so it still might be close & buzz. The 2nd front option would be about 27" allowing more clearance but that's a short sidewall which can lead to rim bending issues on bad roads.

Rears won't be an issue.....

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
