NOT A GREY SIDEWALL - that is the rim you are seeing in photo = [ALL BLACK TIRE] KENDA OCC Stingray replacement tire.  (no stingray logo) Bike in photo has this same  tire on front and back... 

follow this link for REAR INNER TUBE:  https://www.pedalchopper.com/bicycle-parts-accessories/tubes/

3 inch wide KENDA front tire to match the rear tire in this section - it will fit on original rim and inside original fork set.  You may want to upgrade to larger inner tube just below here.

24 X 3.0 INNER TUBE FOR MATCHING [FAT FRONT ] TIRE.

Will fit in stingray frame - this is about as large as you can go on the NEW ERA / OCC style stingray frame. tire includes a half link and master link as you will need to lengthen chain slightly for rear brake [cable] to clear top of tire.  NOTE: original tube can be used / over-inflated to work with larger tire - however, if you want a larger tube also [see next box just below].  This is an e-bike quality tire so designed for longer tread wear...  THIS TIRE WILL FIT STINGAY BUT THIS IS ABOUT AS WIDE AS YOU CAN GO - IF YOU PLAN TO USE REAR FNDER.

This motorcycle inner tube is like 5 times more durable and will fit perfectly for this tire...  It is actually a 16 inch x 3.50 inch tube but (in motorcycle /american sizing)  Which is correct size for this tire.

THIS TIRE MOST CLOSELY RESEMBLES ORIGINAL STINGRAY TIRE - 20 X 4 1/4 with BOA tread pattern.  Basically same as original - but NO" STINGRAY" writing / logo on side wall.

these are e-bike rated for longer wear.... 

SELLING TIRE ONLY HERE - [rim and inner tube in photo not included] This tire is only available from my dealer in Germany.  When I order them I always order like qty 3 or 4 but if they are en route to me [from Germany] when you order => may take upto 2-3 weeks to ship from me to you.  However, I always try to keep a few on hand - but in the event I am re-stocking there  may be a bit of a wait...

Large diamond shaped side knobs provide the grip you need in corners, while the tread knobs get smaller towards the center for the ultimate speed and traction. And with its balloon-style structure, you’ll feel like you’re floating on air
