You are absolutely correct, sorry about that.

So here is an example:

Rim option
14"
15"
16"
17"

Tire option
Goodyear
Goodyear 14"
Goodyear 15"
Goodyear 16"
Goodyear 17"

Firestone
Firestone 14"
Firestone 15"
Firestone 16"
Firestone 17"

As you can see from the example above, if I selected the 15" rim button i would like all the tire size below to filter to the proper size.
