28" bike tyre &/or tube (The Camp AL1)

A freegler kindly let me have a bike with a larger than average wheel size. It would be good to have a spare tyre and or tube even if pre used in case of puncture. 28 x 1 and 5/8 x 1 and a half . Will collect within reasonable distance say 5 miles . Apologies for frequency of repost but I keep getting an e-mail asking me to withdraw or repost. Thanks for reading
