    are there different 20" tire sizes?

    I bought these on eBay
    http://cgi.ebay.com/ws/eBayISAPI.dll...tem=7132897697
    I did not think I would get them for my minimum big. I asked the seller what PSI they went to and he said 100. Though they only go to 85 psi.
    Well I get them today and decided to change the tire I had on my bent. I just bought a new front wheel with a velocity 20 bmx deep v rim. Well the tire that came with it has always been very hard to remove. On the new rim I could not get it off. So I said I have two tires here so I just cut the wire bead and removed it. well only to find when I went to put the tire on it is way too large. It is about the same size as the outside diameter of the tire I just removed. But it does say 20 1 3/8 on it. So what gives? Are there different 20 tires? Should I see about getting a refund?

    Fractional tires (20 x 1 3/8) and decimal tires (20 x 1.5) have different bead diameters. Sorry.

    hey, primo comet tires also come in decimal sizes and are availble in many different sizes. they are rated for 85 psi, but you can pump them up more if you want, it's no big deal. i rode a 20x1.75 comet for months with 110 psi riding ramps and only flatted a couple times, nothing unusual.
