If it helps any, its 15 x Id guess 16? The Hoosiers say they are 18.5 wide, and they stick out a little further than the rim...
i wish i was a SLOT......Errr............ well.i................... that could be any number of wheel manufacturers.it MIGHT be stamped inside. but if i had to guess you could pick from one of the above names and get it rite
Indy Slots were made by US Wheel if I am not mistaken - at least they were when I sold them at the tire store in the 70's US Indy Mags were a trade name, and if I'm also not mistaken, recently the original owners son just reacquired control of the name and is making them again.
All the US Indy's I have are cast with US INDY and the size on the back of the rim. Is this a wheel you have or just a pic you found?
the four step downs at the edge are a good indicator that it is probably wider then a 10" width....personally i like it when they don't have a step down at the back by the centers...i have RI (rocket industries) on the topolino...they also have the a smooth transistion from the hub area to the outter...makes em look wider,,,, my new mags for the front don't have any brand on them..and they also lack an inner step down.... so i guess i'm no help with IDing yours.....
I have not seen anything on the back of them, and Steve... I have them, well 2 of them. I will try to look at them in the light tommorow....Thx
