will 305's fit?
 

i went from 275 30 19 on a 9.5 rim now i bought 10.5 19 and the 275 looks like a rubberband on the rear so i bought 305 michelin's. I know 315 need the bump stop grinded and that piece beat in so they will fit, so will 305's need it too?

All depends on your wheels offset. Shouldn't be a problem if your around 45mm...

i think i'm at 56 so i should be in clear good thanks man

56mm offset indicates that your wheels will set further inside the fender when compared to 45mm offset. That's a pretty deep offset, so you might have to do the BFH mod :judge:

the difference between 45mm and 56mm offset is .433 or about a 1/16 under 1/2"
...so you might have to do about 1/4" of BFH? Keep in mind you get some flex going around turns.

i had to beat the crap outta the inner fender but they finally fit lol let me see if i can get a picture

Looks really good... glad you got it to work!
Was it even on both sides and how much past 1/4" deep did you have to pound the inner fender?
