    Sizing tires

    If someone doesnt have a hot box or a spare oven, i got to thinking could i use either near boiling or boiling water to submerse the tire in to heat it up for sizing?

    I used a kerosene heater in a pinch, just set the tire on top for a bit, worked well

    Say with a hub on a bad or old axle or something similar. When you race on such a tight budget as to not being able to buy the finer things in life you have to compensate at times and get creative lol.

    Hmmmmm that just gave me an idea.... Live kinda close to a small airport i wonder if they will let me hold a tire behind a small lear jet as it takes off? Lol jk but what actually made me think of that is maybe as im working in the shop, i could place a tire in front of the propane torpedo heater at a good distance away of course and rotate it every few mins till up to temp

    Submerged tire and boiling water Sounds like a trip to the ER.
    I fried a Burris on the propane grill; don't try it.
    How about an electric fry pan with a tin house to hold the tire and heat in. Actually looking at my Weber charcol grill it should fit both.
    Or a metal garbage can and heat gun / electric fry pan.

    Boiling water sounds like a lot of work. All of the suggestions above will work. I use a garbage can quite often but found that my heat gun was too hot. Cheapo hair dryer works good. I have also put them in the cab of my truck on hot sunny days. Free and easy.

    The metal trash can and heat gun sounds like an easy alternative!

    I dont think the cab of my truck is gonna work in ohio this time of the year. Right now its 36 out and snow on grass. It didnt stick to roads, driveways or sidewalks but did cover the grass.

    To increase the size of tire, you can just add about 20 psi and leave out in the sun to grow

    All of this has helped. I just started in go karts this past july and only had 1 set of tires last season and was an absolute junk set of tires to start with. I have purchased some used but great tires and wanted to step up my tire game this season. I started out on an unknown kart that was fully adjustable but outdated then traded that one off and bought a phenom for the last half of the season and struggled with the handling of it. It would push like a dump truck.

    The phenom should be a great kart for your area, either tires are wrong or setup

    Also I just want to add one more thing...leave the air out on the left side and leave about 10 psi on the right side...this will help to keep the stagger through out the week

    I'll agree with Jamie. That Phenom will be great here in the midwest.
    I can help you with set-up & scale numbers for just about any track - as well as tires & prep.

    If you look on craigslist, you can find cheap/free ovens -- search "curb alert."
    An older electric oven works very well for sizing tires and costs you nothing.

    I was at a swap meet over the weekend and saw several hot boxes (home made and commercial) selling for very cheap prices. Keep your eyes open -- there are deals out there.
