I think that may have been the size of mine when I purchased it 10 years ago. I took it in to Discount Tire, and the attendant just looked at them and asked me how long I had those? I told him I didn't know how old they were, but they came from a 1970 Hilo. That was when he told me they hadn't been using that number system for many years. I remember they had an "F" in front of the numbers, and they were in very bad condition. I believe he measured them, and put on some Carlyle's. The tires are a very tight fit to get them in the tire wells. I have to deflate them to get them installed.
