I agree with Greboth. A few different tasteful types of wheels to represent the brands already in LFS can't really hurt things.
Also due to different mass concentrations wheels are like the engine's fly wheel, they can affect the way the car revs up and down. A high moment of inertia will cause it to accelerate more lowly but bleed off energy more slowly, which could be advantageous on Kyoto GP's long uphill climb. Wheels with a low moment of inertia are the opposite, they can quickly change state, so they become the best option for tight courses where one much often change from braking to accelerating ad must squeeze the most acceleration and deceleration possible from a short space.
