Cybertruck Tire Rub / Maximum Tire Clearance Calculator -- Claude AI Built

[Bkb13]

I went down the rabbit hole last night and need your help. I've been working on a little project that I hope will be useful for our community, and I need your help to test and validate it.

What is it?
I've created a Cybertruck Rub Calculator - a React app that uses the Pythagorean theorem to predict whether a tire will likely rub against the truck body. Let me tell you, these AI models are great, but also I've learned that I need better prompt engineering skills. I had to rewrite the prompts about 50 times before I could get a working product. Too many hallucinations from the AI model had me chasing rabbits.

How it works
The calculator estimates the Maximum Rub Point, which I believe to be around 19.85 inches. It takes into account tire size, wheel size, and offset to make its predictions.

What I've tested so far
I've run a couple of tests with the following setups:

1. 325/60-20 tire with a 20-9 wheel and 18 offset Result: Rubbed against the back of the headlight
2. 35/12.5-20 tire with a 20-9 wheel and 18 offset Result: Just perfect, would barely rub (fixable with a little heat gun action)

Why I need your help
Here's the thing - before starting this project, I had no idea what an offset was! While I've done my best to ensure the calculations are accurate, I need more data points to validate my work.

How you can help

1. Try out the calculator: https://cybertruck-b9ay2yxug-bkb13s-projects.vercel.app/
2. Input your wheel and tire specs
3. Compare the results with your real-world experience. Please let me know if the front and rear peek is accurate as measured from the top of the fender.
4. Let me know if the predictions match what you're seeing on your Cybertruck

A bit about the project
I put this together on a whim last night, learning how to create a React app with Claude (an AI assistant) and how to deploy it on Vercel. It's been a fun learning experience, and I hope it can be useful for our community.

Your feedback will be invaluable in refining this tool. Let's work together to make tire and wheel selection for our Cybertrucks a bit easier!

Thanks in advance for your help!

I think I just turned off authentication. Sorry for anyone who just tried to get access to the app earlier. Let me know if you see it please.

But once you get to the tire size and wheel offset that rubs that solves any question above that size ? I have 295/55/22 on a 9” wheel +31 offset no rub.

I put your size int he app and it doesn't turn up red, so the app seems to be working. I believe that if the Value for the Maximum Rub Point is 19.85" or greater than it will rub. Your Max was 19.28 inches.

Is your front poke .8 inches, and rear 2.3 inches?

I tried a 325/60-20 with a 20x9 and 18 offset and It absolutely rubs. Here is the calculator showing red for the Max Rub Point.

Great idea. I'm running stock ATs so no help from me.

Perhaps some diagrams that illustrate what the various terms mean.

This is great. Leave it to a Cybertruck owner to build this

Good idea. I'll attach one.

I want your free time! Thanks!

Here is a cross diagram of the dimensions that are important.

Love this. Looking at a set of Fuel Rush wheels 18x9 with a 20mm offset and 35x12.5x18 tires. Seems like it will fit!

what an incredible tool.

Thanks for coming up with this calculator. I just ordered some Toyo 305/55/22 EV tires for Vossen +30 , 22x9.5" wheels. Let's hope they work out, lol.

I have 295/45/24 Nittos with 24x10 Vossen with 25 offset. My MRP is 19.24 which if I’m understanding correctly should not rub, but I am currently looking into some turn noises that sound like rubbing.

At ride height? Or at full suspension compression (bottom out aka bump ) . Also at full wheel lock/ turn ? That would be the worse possible situation for tire clearance . Full bump (suspension bottomed out) + wheel turned . Off roading will see that condition or big pot hole / curb/ speed bump . Alignment will also affect where the tire will ultimately sit . On top of all that the rubber tire can deflect too a bit . It might bulge during hard off roading or with low tire pressure. cyber truck has about 12 inches of wheel travel so make sure the tire clears at FULL BUMP and with steering locked.
