Fusion 360 - (1/3) Parametric Tire and Treads for Beginners/Intermediate Users - Lesson 12 (2023)

In this multi-part series of tutorials, you will learn how to make a parametric tire, which means that at a simple adjustment of a parameter, you can change the entire width, aspect ratio, rim size, and number of treads. You will also learn about cartesian planes, tangency, and so much more. This will test your knowledge of all that you’ve learned through prior tutorials made by the Learn It! Channel. You will learn a ton during this series. You will only create the tire without treads, sidewall text, or appearances in this tutorial.

When I was testing like you were at 30:35 I noticed at larger sizes the inner profile gets very square behind the 1-inch radius created earlier. I edited the fillet with a second selection set, got lucky in hovering over the first set and seeing the dimension code (d24 in my case), and set the inner fillets to d24 - WallThickness. Not sure if that's best practice or not, but it's beautiful! I wouldn't be close to this point without all the tutorials leading up to this one. Thanks again!

[@learnitalready]

So good to see how much you’re trying to understand and apply the fundamental principles you’ve learned in fixing problems. Yes, that radius is one major thing to consider in making the tire FULLY parametric. I would probably base that value off of a percentage of another parameter. Awesome work!

Some tires in the US are in inches, usually larger off-road tires. The common ones are 33x12.5r15 and 36x12.5r15 found on a lot of lifted Jeeps.

[@learnitalready]

Good to know! Thanks for providing some additional info and clarification

[@user-zk7tw5os1g]

This tutorial series is fantastic - thanks

[@learnitalready]

You're very welcome!

[@davecummins6581]

Love your work. Thank you!

[@learnitalready]

Thank you for the encouragement!

[@WardInstruments]

Beautiful work. I was dreading a 32-minute video, but this is fact-packed and consistently interesting. Very professionally produced.

[@learnitalready]

Wow, thank you! Very encouraging to hear.

[@jeffgraham2653]

Very helpful. Been watching all the Beginner videos and never thought I would make it this far. I had and still am tweaking the dimensions and code to scale a full size tire down to a usable 1/25 scale for 3D printing. Thanks.

[@learnitalready]

I love it! Thanks so much for the encouragement. Glad that you’ve benefited from our tutorials. Please tell us what you think of the next 2 on the parametric tire series. There is a bunch more in those too. Thanks again! Keep up the good work!

[@minnesotarc7964]

Little late in the game but anywho. The aspect ratio is also called the tire profile. This is the height of the sidewall measured from wheel rim to top of the tread expressed as a percentage. An example would be a truck tire 245/70R17. They have a longer profile from rim to thread compared to a BMW 245/40R19. The width is the same 245mm but the profile is thinner at 40% compared to 70% of the width. You can't use the same tire for both because the tires have different diameters, but if you take the truck tire 245mm convert it to inches [9.65] and multiply it by the aspect ratio 70% [.70] then the height from the rim to the thread is 6.76" compared to the BMW 3.86 inches. An aspect ratio of below 50 is a tire considered a low-profile tire. The lowest is an aspect of 30 I think. Living in a state with 10,000 potholes, I prefer to have that 3 additional inches to protect my rim from some major damage.

[@learnitalready]

Awesome! Thanks for the in-depth explanation!

[@frederickmith]

Great work! I'll be using it to make a set of tires for my Lotus 23B build.

[@learnitalready]

Thanks so much! Would love to see your final work. If you’d like, please send a picture to our Facebook page.

[@pietrononame4945]

BTW. 12:12. How to turn off checking units because none of the formulas work after the last Fusion360 update? Now, where there are formulas with different units the resulting value is out of the blue.

[@learnitalready]

Thanks for letting me know. I’ll have to check it in my system too. Can you clarify one thing please: when you say “where there are formulas with different units the resulting value is out of the blue” can you give me an example please? Thanks!

[@Intervaloverdose]

[printed their first part this week] Now this is a drop. Can't wait to watch this.

[@learnitalready]

Awesome! Let me know how you do with the tutorial.

[@myproductdeveloper931]

Your a beast. I'm always looking for tips to go faster. I'm going to raid all your videos.

[@learnitalready]

I love it! Thanks for the message and support. 3/3 is coming out soon for the paramedic tire. If you like tips to go faster, part 3/3 is a game-changer. Hope you benefit from jt and our other tutorials. Thanks again!

[@boboscurse4130]

To bring up the Diameter Dimension make sure you click on the center line and not the endpoint of the vertical line. I spun my wheels for a little while wondering why I wasn't getting the menu when I right-clicked.

[@learnitalready]

Thanks for sharing what you’ve been learning along the way. Great job making it to where you are now!

[@rothens]

I still couldn't find it :( No matter how I tried. Can you elaborate a bit please? Thanks

[@erickcandanedo3210]

wow... kind of advance for me.. but I think that I the rate I am going, this will come in handy this year. first time i hear the explanation obout quadrants Hey.. you mentioned in another group about your students... you are a teacher for fusion?

[@learnitalready]

Hello! Thanks for your comment. Have you had an opportunity to view the other tutorials? If you follow each video, this won’t seem so intimidating. Our goal is to help to slowly and steadily build the confidence of each of our viewers. And, yes! I am teaching Fusion 360 at the moment to 3 groups of students. It is very enjoyable work.

[@erickcandanedo3210]

@@learnitalready no. I have just watch the body and arms of the lego. but for sure i will do.

[@learnitalready]

@@erickcandanedo3210 Awesome! Keep up the great working learning Fusion 360. It is a fun process learning such amazing software.

[@johncowan5759]

Hello. Tried the dimension tip at 18.30min. Command didn’t appear after right click. Has update changed the operation?

[@learnitalready]

Hello! Thanks for letting us know. I will check it out.
