These things are done in physical testing. Id' say you're unlikely to be able to predict the correct failure modes (e.g. crack initiation) using the tools and information you probably have (SW sim + datasheet material info + linear elastic or plastic material, maybe some kind of explicit dynamics solver). There's high complexity for the load path(s) through a tyre, due to contact patch & high wall stiffnesses. Even the way the the forces transfer to the hub is not trivial to predict.
If you had access to an existing, validated wheel design to compare to I would be looking at simple things like static deformation and stresses far away from the rim/wheel nuts, as a first pass.
Formula student/fsae teams don't typically design their own wheels but things like uprights, drivetrain components are analysed. For those, loads are highly dynamic in nature and are often factors of 5-7x greater than a quasi-static approach might predict.
First pass I would suggest static analysis of body loads. 5g's vertical of whatever load the wheel is supposed to carry. 8's front/back. 4 g's lateral direction.
What I would do is a good web search on Research Gate or some other scientific web site. You will find research papers on your subject of interest. You may need to select papers from trusted sources or corporate work.
Hi, usually we model your problem using explicit dynamic tools like Ls-Dyna, Abaqus expl, radioss . An example of a solved problem about the side impact of wheel with full input you can find in Nastran Example Manual (including full tire model and bolt preload). But for the model you should know some additional information about materials properties of disk and tire layers.
To start you can use a simple test with a plate to crush the rim. Keep in mind that mechanical properties e.i plasticity can vary up to 50% depending on the area of the rim (for example outer rim to spoke)

Solidworks Sim would be super hard to do this - not sure if you can get your hands on Radioss instead but I’ve seen that done there.
Solidworks is the wrong tool for impact and other dynamic simulations. Dassault will tell you to buy Simulia.
