OTK has a new wheel. The MXQ. I don’t know a lot about it. I think I know the reason for the different wheels, but I’m using this new wheel as an excuse to make a post and see if my assumption are correct. And also too see what people know about where the MXQ fits in?
MXJ = stock OTK wheel. Made from cast magnesium. Heats up faster and maintains a higher heat. Used for cold track and low grip applications.
MXC = same profile as MXJ but made from forged magnesium alloy. Forging allows for heat treated alloys that have better thermal and dampening qualities, and limits porosity. All of this results in better heat dissipation and better lifting on a gripped up track.
MXL = same forging as the MXC but with a low volume profile. The low volume allows for less air pressure and provides a bigger yet thinner surface area for cooling. This allows for better temperature regulation. The lower pressure allows more sidewall fold & side bite. The longer large internal radius also has a greater bending moment (is stiffer). The wheel is used for hot (long?) races and tuning around grip.
MXQ = MXL’s low profile shape yet the lip from the MXC? It uses the same forging as the MXC & MXL. I’m not sure what the advantage of this design is. Hearing that people that tested it like it. I also heard there were issues with the MXL exploding under pressure (is this just a replacement?). Thoughts?
