My truck is an 84 C-10 with 5/7. The tires I ordered are Toyo Proxy.
255/40-20's up front on 8.5's w/5.25"BS will fit. The main concern will be rubbing the top of the inner wheel well on bumps/dips w/the 5" drop. Mine does on larger bumps in the road or smaller ones @ greater speeds but my front wheel/tire combo is < 27" tall; the 255/40-20 is 28" tall.

The 295/40-20's on 10" w/5.00"BS won't be a problem @ 7" drop.

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.

The issue we all have when running large wheel and tire combos up front is not the fender or lip, it's the inside of the wheel well. It will only rub when you hit a nice dip or bump but don't worry you're not alone.

DITTO... and I will add this: remove your jack, bolts, etc. from the drivers side wheel well. At least install C/S or small head bolts (if you dont remove the jack).

Re: 20 inch wheels with 5/7 drop

Thanks again for all the info. I am going with the 255/40/20's up front. I need the ground clearance for my lower control arms.I will take the jack out so I dont have to worry about that . I guess I will take my chances with the inner fender clearance. Thanks again.

Wink Re: 20 inch wheels with 5/7 drop

have 5.5 front drop with 8 in. tt 2,s 255x17x50 . Only problem is lower control arm rub when making sharp turn ( NEED TO GRIND OFF A LITTLE WHERE THE BACK OF THE RIM RUBS & SHOULD BE OK ) No problem with upper fender rub , still have bump stops on . if bump stops were removed im sure tire would hit fender well on bumps & dips . Hope this helps . You also can cut a little off bump stop & be ok.
