60 gmc 17.5 6lug wheels

i have a 1960 gmc that came with the orginal wheels which were 6 lug 17.5. the problem is no one makes a 17.5 tire except for medium duty trk tires which are way to heavy for a half ton. does any one no of anyone with lt trk tires that are 17.5 or is it possible to modify my wheels to 18". any help is appreciated  

I've got a set of 16" wheels with the 6lug pattern from a 95 GMC that will bolt on your truck that you can get lt duty truck radials for. Or you can always use a set of 6 lug rallys from a 4x4 chevy truck. They are 15x8s, and will also fit your truck and look good. If you're interested in the 16s get back to me on this blog.  

thanks smurf but the intention was to keep it orginal lookimg with the hub cap clips and all  

Give John Budd a call at 1-330-947-2002  He might be able to help you out with some stock looking wheels with the hubcap clips, that you can put more suitable tires on. Tell him that Smurf from Canfield sent you.  

If you decide you do not want your 17.5" wheels I'll buy them from you. I have a 64 Chev 4x4 that I would like to put them on. http://www.universaltire.com/cart.php?target=product&product_id=25346&category_id=343 makes sells Mud/Snow.
