  3. I was wondering what size tire youI need for a predator with a212cc engine. I’ll appreciate it if youI can help

    1. Hi Lacroy,

      Thanks for reaching out and happy to help as much as I can.
      Is this for an off-road go-kart or a racing go-kart?

      If it’s for a racing go-kart I would stick with a tire size that fits your current wheels.
      Unless you’re looking new set of wheels + tires, then I can recommend you something for that.

      Have a great day!

  4. Hi I just have a quick question. I’m building a motorized drift trike and got a great deal on some 11×7.1×5 tires and was wondering if 7.75×5 rims would be the right rims to fit those tires . Any help would be appreciated I saw from your chart that tires that size fit those rims just wanted to make sure.

    1. Hey Zach,

      Thanks for writing in and happy to give my 2 cents. It looks like you’re looking at the Hoosier R70, right?
      When you match your tires with the rims, you have to make sure that the rim diameter on the tire and the rim match 100%.
      So in your case, if they both indicate that they are 5″, that’s perfect.

      For the tire and rim width, you can have tolerances up to about 1 – 2 inches. This means is definitely possible to fit a 7.1″ tire on a 7.75″ wide rim.
      On Hoosier’s website, they even recommend that: https://hoosierkartsport.com/products/ (right column)

      Just take note that if the tire width is smaller than the rim width, it will have a slightly rounded shape.
      If the tire width is larger than the rim width, it will have the opposite effect. But the 0.65″ width difference absolutely fine!

      If you’re using a sleeve on your tires, then it shouldn’t matter anyway.
      Hope this helped!

  5. Hi, Quick question.
    I normally use Vega Yellow XP 5″
    Can I fit a Vega Yellow MCS 6″ on the same rims?
    Thanks in advance

    1. Hey Silvia,

      They won’t fit if they have a different rim diameter.
      There is only leeway on the tire width and tire height.
      Hope this helps!

  6. I’m wanting to buy wheels and tires. I’m not quite sure what size I want I’m thinking bigger is better but anyway I’m putting a 5 speed 200 cc motorcycle motor on an old racing kart frame . Mostly the kart will be used on streets and in the grass. I definitely like the idea of wide slicks and am curious. Of what compound I would want. I wanna do burnouts all the time and play for now. And maybe buy a second set for drag racing later. I’m somewhat budget minded. I’m not sure if I want the same wheel and tire size for front and back or not. Thank you for all your help.

    1. Hey Dylan,

      That sounds like a load of fun! Would love to see some pictures of it once you’re done!
      Personally, I would go with wide slicks for grip on asphalt.
      With a 200cc engine, you’ll be able to make any go-kart drift on any surface anyway, especially on grass.
      You could even look at some used slicks that are lightly worn.

      Good luck with the project, Dylan!
