Rover tires

[Jimtheguy12]

I blow the rear tire this aft on my 30 klm old rover st and all the bike shops in Calgary have every size BUT 26 x 4. Is there any other size that will fit properly? The hole was too big for slime and finding Tannus inserts I would better luck buying a unicorn.
Thx

I don't know of any others that will fit.  I actually ordered some before my bike arrived just in case as i expected not to be able to find them around locally.  Interestingly enough i have yet to have a flat, must be because i had tubes at the ready...
