I am looking for someone who uses Phoenix race slicks 29.5 X 11.5 X 15W
part number PH376. I am hoping that you might have an old worn out one that will hold air that I might use as a test tire for clearance purposes. Recently I got a used 29.5 X 11.5 x 15 PH362 from a member here and was surprised how flat the sidewall was as compared to my old M/T of the same size. So now I think that the wider "W" may just fit and give me a wider footprint. Contact me at moparjohn@frontier.com if you can help.
Thanks!

John, I have them on my car but don't have a worn out one. I take take measurements for you. They are on 12" wheels but would fit on 14" wheels as well. Jim

The W tread is 13.5 compared to 11.9 , the section width on the W is 15.5 compared to 14 , suggested rim size on the W is 12 compared to 10, all other dimensions are the same.

Thanks for the replies and dimensions!
I would still like to get one of these tires and mount it up.
When I got one of the non "W" slicks I got 14.30 at 12 PSI vs the advertised 14.0 on the section width. I will be real close in the section width area and want to make sure before I buy a pair of new ones.
So again if anyone out there has a worn out "W" that will hold air I will come and get it or pay for the shipping.
Thanks! John
