83 Chev K20 Military / Fire Rescue
« on: July 20, 2017, 03:27:52 PM »
I won the bid on this 83 K20 350 np208 14 bolt rear corporate 10 bolt 400 turbo 4.11 gears. But it has 16.5 rims and tires which they don't make any more. My question is can I put 15 inch rims with 31 inch tall tires with out interference on this pampered cherry beast? Thank you from Kansas .

you can fit 15" wheels if you grind on the front calipers a little. 16s of course will fit with no issue

I would run 16" wheels. Not worth it and you might need wide wheels with right back spacing and a spacer and grind down calipers. Just my opinion

the only reason i would run 15s is if i had a set of 15s already or could buy a set cheap

I found some 16 inch 8 lug that fit good over the front disc brake. Thanks for input.

Bidding on these old trucks is addicting.
Any pictures of it?

Sorry I don't know how to post pics at 70yrs old but maybe I can find somebody to do that. I can give you some history ,our fire chief in 1992 bought the truck at Fort Rielly Ks and been in service tell a year ago. It came with a 1200lb extendobed and Pro series topper used for carrying jaws of life and generator and wired for all the emergency lights. Every thing leaked from sitting but every thing is fixed and sits in my garage ready for more years of service , all for $1701.00 .
