Building vehicle wheels layout

Dear All,
I am building an application where I am creating each type of vehicle wheels layout. What I plan is that first I will choose the number of wheel/tyres. Then I would like to build the configuration to each label the different wheel/tyres to be stored in the database. I do now know how to go further on the assigning of the tyre and their relevant label. I have an idea such the front tyre I will label LF1 and RF1 etc. I dont know how to keep this data accordingly.
