So with thousands of choices of tires, how do you determine what one is best? Simple, you look for tires that are designed to do what you want without too many trade offs else where.  
Ability to draw 2D schematics/diagrams. - you need to do this if you are trying to make a pack with a certain dimension constraint. use of CAD is encouraged.


For a e-bike commuter, that is generally go a long distance on road, with some minor off roading. What we have found out for such conditions is the most important thing is durability and puncture resistance, followed by low rolling resistance and moderate traction on roads, roads with debris and trails.
You know how to use the [https://ebikewiki.com/index.php/Simulator|Grin simulator] - You need to know how much current your battery will be drawing.


The best tires we have found for that are the Schwalbe MTB plus line of tires. These tires come with 5mm of extra hard rubber armor inside them to protect from punctures and are made of some of the hardest tire compound found on bikes. 'But I can't afford fancy armored tires' you might think. They start at $44.49cad or $31.99usd, hardly twice the price of the cheapest tire on the market but will last easily 10x longer, Some users have reported over 7000 miles on a single tire in e-bike usage. You can't afford not to buy armored tires, especially when a puncture can leave you stranded.

Marathon Plus MTB on Chain Reaction Cycles [https://www.chainreactioncycles.com/ca/en/schwalbe-marathon-plus-mtb-tyre-smartguard/rp-prod143787 Canada] [https://www.chainreactioncycles.com/us/en/schwalbe-marathon-plus-mtb-tyre-smartguard/rp-prod143787 USA] one of the better tires for mountain bikes, comes in 26", 27.5" and 29" in widths 2" and 2.25".
Ability to read battery cell datasheet. - As the wiki page becomes older, more cell info will be added to the page; but for cells that are not on this wiki/internet in a simplified format, reading datasheet will be necessary.

Marathon Plus Tour on Chain Reaction Cycles [https://www.chainreactioncycles.com/ca/en/schwalbe-marathon-plus-tour-tyre-smartguard/rp-prod52621 Canada] [https://www.chainreactioncycles.com/us/en/schwalbe-marathon-plus-tour-tyre-smartguard/rp-prod52621 USA] Slightly more road designed tire for mountain bikes, comes in 26" with a width of 1.75" or 2.0"
 
Marathon Plus Road on Chain Reaction Cycles [https://www.chainreactioncycles.com/ca/en/schwalbe-marathon-plus-road-tyre-smart-guard/rp-prod24544 Canada] [https://www.chainreactioncycles.com/us/en/schwalbe-marathon-plus-road-tyre-smart-guard/rp-prod24544 USA] Have a road bike? Schwalbe has you covered with armored road bike tires too! Comes in 650A and 700C in widths 25C through 45C
 
Note Chain reaction Cycles ships world wide, just change the drop down at the top right to get your countries prices. they also offer free shipping above a set amount, generally around the cost of 2 tires.
 
Do note that Marathon plus tires are all made of an exceptionally hard compound that wears much slower then most bicycle tires, but trades off some grip to do so. They are rated for e-bikes and speeds up to 50kph while most bicycle tires are not designed for such high speeds and few other manufactures will actually rate a bicycle tire for speed.
