At our local car show I saw a 54 3100 and the tires were 7.50R16Lt. They are narrow just like the original bias ply from Sears. When I asked about them he only said he got them 30 years ago. They still looked good. They look better than the 215/85/16 than i am using now. I have not checked yet,but they probably are not made any more. Has any else ever seen these tires? Just curious.
