how to buy go kart tires and wheels (rims)

[PatiencePaysOff]

I would like to know how to read the notations (the numbers) engraved on a go kart tire. Therefore, how do we relate these numbers to the right wheels we want to buy afterwards. Do they have to exactly match? This is for a slick tire I want to purchase on Kijiji :http://www.kijiji.ca/v-pneus-jantes/longueuil-rive-sud/4-pneu-pour-go-kart/1075299006?enableSearchNavigationFlag=true and the wheel which I want to purchase from cometkart https://cometkartsales.com/Williams-1-Piece-Wheel-5-X6-Thru-7-X6.html
I know there are probably not matching, but this is where I need help to make the right pick next time.
Thanks everyone!

Those rims will fit a tire thats 6" to 7 3/4" wide, 6" around. When looking at tires the first number is the height, second is the width, and third is rim size.

Those tires are for a 5"rim so they will not fit, besides that they are 11" wide at the bead (surface that seals against the rim) so again, will not fit. The height of the tire doesnt matter when comparing them to rims.

These rims would fit those Mojo tires fine:

Or Spindle mount front: https://cometkartsales.com/Douglas-DSM-Front-Wheel-Polished-5-x5.html

Rear's : https://cometkartsales.com/Douglas-Polished-1-Piece-Wheel-8-X5-SKU12992.html

Here's a link to a good racekart tire/rim fitment chart:

Have you already confirmed if your kart needs rims with the metric or american 3-bolt pattern?
