wheel/tire help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys,
hoping this is in the right section

I have a '70 C20 (spring front leaf rear) which I have swapped 5 lug '73-'87 A-arms and spindles, and rear end into so it is now a 5 on 5 bolt pattern.

I am stuck on what wheel I want to run on it but have my eyes on some 15x10 rally wheels. When the truck is done I am thinking I want a 3/6 drop in it to bring the whole thing together.

Will the 10" wide rally fit on the front without issues? or do I need to stagger it with a 15x8 on the front. I would rather do the homework and get these answers now rather than when the truck needs wheels to be finished. I used the search but never really seen an answer I was looking for. Any help would be appreciated, thanks

My 68 C-10 has 235 70 15 tires on the front on 7 inch wheels and 255 70 15 tires on the back with 8 inch rims. I like the 70 series tires because they fill in the wheelwells better.

10" is pretty wide for the front depending somewhat on your offset. You would probably be better off going 7 or 8" on the front and 10" on the rear. JMHO.

No help on the rims but just so you know a 3/6 drop will sit about a inch and half lower in the back than the front
