My next tire softening test will be using a gallon of fedron. It is used to clean/restore rollers in large printers, etc.

I would be hard pressed not to try the 295/50/16 Galaxy's. That is unless you must have a 30" tire.

On the Cooper Cobras be aware that there are two different grades (speed ratings) that are sold. The 118mph version is carried by most however they can order the (130?) version for a little more. Tire rack has both fwiw.
