Removed and reinstalled the rear tire today (26x 1 3/8 on a Raleigh Sports). The bead is not seating in one area and it has a flat spot. Deflated and powedered it up like a new born but still has the same issue. I did install a new tube and rim strip. I thought that I read some where that over inflating and letting it sit does the trick. am I missing anything else?

Thanks.

Lubricate, soapy water anything really, then pump it up, err, let the air out to lubricate it, then pump it up and watch the bead, it's manipulatable, don't let the tube get between the tire and rim.

I know I have had to use a bead seating tool on some that were really stubborn on a set of Schwinn 26" tires before even with lube and higher air pressure.

Silicone spray is a good tire lube, just clean it off the rim.

occasionally - you can get a tire that just won't seat right - its more rare than common - but i have had it happen - sometimes i think it can just be an incompatibility between a particular tire brand and a particular rim

It's so annoying. I had a 27" Cheng Shin tire like this. Every time I got a flat, it was a big effort to get it right. Once I paid the LBS mechanic to do it for me, because I just don't enjoy doing this. Eventually, I just chucked the tire and vowed never again to buy another Cheng Shin tire until their reputation improves.

+1.....I run over the entire bead/rim interface with an old
small paintbrush with shortened bristles dipped in diluted
dish soap (both sides)........then inflate and bounce a little.

If it has not seated by then, I start overinflating until you
hear the pop when it seats. If you're unlucky the pop is
when it blows off the rim.

what does work for me sometimes is a slow inflation process - 10 psi at a time - stop and massage the tire around - if it is looking off - let some air out and repeat - sometimes i will put a little in and let it sit for awhile too - but yeah there are those tires that are just 'difficult'

funny though - i have had great luck with CST tires

if it's the same tire that was on there, you probably mounted it like that the first time and now it's "stuck" that way.

When I pulled the tire off I found alot of rust. I spent some time with a brass brush cleaning it but it its not pretty. I was tring to avoid soap/water because of all the rust so I will try some silicone etc. Had to work all day so may not get to it until the am.

And you're the one who convinced me the Cheng Shin tires are a good buy.
FWIW, I had the same problem with the first Panaracer Pasela TG I bought. Nashbar took it back.

I am still using Chen Shin tires, they make a lot of the private label tires out there as well. Are Chen Shin great tires? No. Do they make some decent recreational level tires? Yes IMHO. The Nashbar Prima 2 Plus tires that I like a lot are Chen Shins.

+1 to slow inflation. I used to directly inflate tires off my air compressor, and frequently had bead seating issues. Then I went to my floor pump, no more problems.

Recently I converted to one of these, I was tired of pumping. This tool (not cheap) allows me to slowly inflate tires. Of course, in typical thrifty bill fashion, I got mine used from a shop that was closing. I would be hard pressed to spend $83 on this tool.
