What tires?
 

I tried to search but it didn't work.
I am a newbie and in the process of building my first ss bike. I am building it to be fun, functional , and have a cool look. I am trying to give it that old hotrod look so here is my question. The tires on it are 26x1 3/8 but I want to run a white wall tire. Does anybody make a white wall in that size or do I have to go to a bigger size? If a bigger size is my only choice what size will fit? Thanks.

but since you're new...

not a super common size, your options are limited, particularly with the white wall specification, but it looks as though Schwalbe does make one.

as for what larger sizes may be possible, we would need to know a little more about the intended rims, not just the current tire size.

hope this helps.

Well I am using the stock wheels that were on the bike originally. This bike was already a single speed with a coaster brake. All that is on the wheels is the size 26x1 3/8, and the hubs are Suntour. Thanks again.
