    Default tire scale?? warning: phd math inside

    I suppose this goes here.

    So im either extremely overthinking this or i am even worse at math than i figured i could possibly be.

    I want 35" tires. Using the magic of mathz, that comes out to 89mm diameter tire in 1/10

    I want 38" tires. Using more maths magix, that comes out to 95mm in 1/10

    at the same time, those are some rather tiny tires in terms of what is in the rc world. i mean you shouldnt be able to bolt 44" tires on a toyota 4 pickup... logically speaking. yet thats pretty much common.. and it goes up and up.

    So am i doing this right or am i missing something here? welp

    Try 1:9 scale? Yotas are 1:9 I think, my raffee landy might even be closer to 1:8.

    Edit- 1/9 35" is 3.9" or 99mm

    1/9 38" is 4.2" or 107 mm

    That gives lots of options, especially from rc4wd, also all the 4.19 class 1 boots from Proline, etc.

    Your math is sound, but if you're building a Hilux/Mojave, it's 1/9th. Dagabba is on the money.

    Broken record here but yeah make sure you know the scale of your body when you’re doing the math. True 1/10 Scale is a pretty rare thing.

    You are not overthinking sir...

    Manufactures do not take the body into account when the apply that 'scale' label on them. This applies even when a scale company sells a body only (take the rc4wd bodies for example). A quick way to roughly figure out scale of a body is to use the real vehicles wheelbase, then compare to the rc body wheelbase.

    So, if you're building a hilux, it's 1/9th scale. So using that measurement you should have some tire options that'll fit into your requirements.

    Was mostly wondering about the math. It not a toyota but for the purposes of this here, i shall pretend 106mm = 38". it works visually
