But that doesnt mean you'll get more tread on the road.
295 and 305 are measured at sidewall buldge. Differences in sidewall, shoulder and tread design contribute to 'tread width'.
A 285 could have more tread on the road than a 305 depending construction method.

you have to remember that 295 means 295mm from bead to bead. Also please take into account what Jim mention. For a specific width you need the proper rim width to support a certain size. Ideal rim width for a 305 is 10.5

those measurements are on the same manufactures tire. Not always the same comparing two different manufactures.
ex my Mich 18x335/30 is 13.1" wide. my Hoosier 18x335/30 is 13.6" wide full 1/2 in difference
And that is just the tread width. the Mich is 13.3" overall width with the 13.1" tread with
the Hoosier 18x335/30 is 14" wide with a 13.6" tread width
The Hoosier is 3/4" Over all wider then the Mich. the Mich needs a 12" rim the Hoosier needs a 13" rim
so compare apples to apples
Hoosier 18x305/30 ----------- - Mich 18x275/35
Hoosier 18x335/30 ------------- Mich 18x335/30
