They are a 6 bolt pattern and fit the 17.5" tires. They also have a series of tabs in the lugnut recessed area for the hub cap. Tomorrow I'm taking them to work to dismount the junk tires and spin them on the balancer.
The question is, did any early Chevy 1/2 ton trucks use a 17.5" wheel? I bought them because the guy said that if they didn't sell, they were going for junk. I have all four and all four have all of their tabs. Are there any hard core resto guys out there needing anything like this? After I get the tires off and take some pictures, I'll post them up in the swapmeet.

It's my understanding the xx.5 series tires were the early tubeless tires and had to be installed on the special xx.5 rims. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | the 17.5 were on the 55-9 heavy duty 1/2T. and all 3/4T, and duals on the 3/4T - should be 3 hub cap clips

The 17.5's will be the same height as a corresponding 16" tube-type tire. 16.5's will height-match 15" tube types. They can be used interchangeably with tube-type tires without affecting speedometer calibration. On the bigger, dual-wheel setups, a tube-type and a tubeless tire can share the same hub, and share the load weight. For instance, a 20" tube-type and a 22.5" tubeless will be the same height, and can share a hub. Ditto for 22" tube tires and 24.5" tubeless. I did this regularly when I ran the maintenance shop for a concrete trucking business.

Nate | | | | | Joined: May 2005 Posts: 33 Member | | Member Joined: May 2005 Posts: 33 | Nate's right. I saw an Advance Design truck w/Napco on ebay (might still be there)& they listed 17.5 wheels.

These had 8-leaf rear springs. A note says "GVW rating is increased by 600 pounds for Four Wheel Drive models".
I'm sure these would have been 6 lug wheels.
7-17.5 6-ply is also listed for 3600 and 3800 models. These would be the 8 lug ones. | | | | | Joined: Mar 2004 Posts: 3,068 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 3,068 | Well, here they are. They are 17.5 by about 6 inches with 6 lug holes. All four had traction tread tires on them leading me to believe that they may have been from a NAPCO truck like Nate said. They are made of thicker guage steel than most wheels that I've dealt with. If they are rare like they seem to be, I would like to pass them along to someone who can use them, especially a fellow 'Bolter. If anyone knows anyone..... I'm gonna list the in the swapmeet too. I'm just glad they didn't get cut up and sent to China, Scott | | |
