Hello:


My problem is tires. No matter what kind of air up tires I get, they keep losing air...I am constantly pumping them up.

I've been looking for size 28 inch solid tires, but I can't find any online. I find 14 inch to 26 inch, but thats it, nothing larger, unless its a motorcycle.

I've looked at solid tires also, but don't find any solid tires for 28 inch rims.


And yes, I've taken it to a bike shop to see if there is anything wrong with the rims, and they said they didn't find anything wrong.



Is there any place that sells larger sized bike tires....specifically the solid tubes or solid tires? I spend more time airing up these tires than riding the bike!!!


Thanks!
