Replace spare with AT4 wheel?

Unwrntd · July 13, 2020

Does anyone happen to know if an AT4 20" Wheel with stock tire would fit in the spare carrier location?

Transient · July 14, 2020

I did the math on the wheel and tire diameter the other day. For those with 20s, the difference between the spare tire diameter and the regular tire and wheel was a matter of 0.9mm.

....if my math is correct,

thanks! but are you good at math?

Could I figure out how much thrust a rocket needs to orbit earth? No.

Can I add 1 and 1 to get the result of 2? Yes.

My math skills are somewhere in between.

The real question is, did I calculate the sidewall of the tire correctly? Many people think it's a measurement of how many millimeters tall the sidewall is. It's actually a percentage in relation to the width of the tread.

For example 275/65x18 doesn't mean the tire is 275mm wide, 65 mm tall, and fits on a 18 inch wheel. It actually means the sidewall is 65% of 275, which is 275×.65=178.75. You then add 18 inches to the 178.75×2. I recommend coverting the inches into millimeters. 178.75×2 is so that you can get the measurement for diameter. The other way is to calculate the radius. In which case the formula is 178.75+((18÷2)×25.4)=radius. Radius times 2 = equals diameter.

I'm not a genius. I just play one on the internet. I could very well be wrong. But, whatever you do, don't divide by 0. I've been told the world will explode.

That's a lot of work, i just use the calculators online

https://tiresize.com/calculator/

But good explanation that i had been wondering lately. Never understand why they could just use 35/12.50/20 for all tire sizes.

Much easier for my brain to comprehend.

haha seems solid to me! though I was never good at math. I'm bad at being an Asian i guess...

At least you're not another one of those dumb middle aged lazy white guys. We already have a bunch of them in society.

Oh, wait! I resemble that statement. Fml! [emoji22]

Brave if you to assume I’m not a lazy idiot! Ha

Sorry I didn't respond earlier. I lacked the motivation to pick my phone up off the table that's next to the couch seat I'm sitting in.

You know what they say about assuming? It makes an ASS out of U and ME. I'm already an ass, so i has 5/6ths of that covered in my end alone.
