305/40/18 on a 18x10 deepdish rim on a 05 - 09 S197

[Laffs]

Keep in mind that wide a tire is going to rock chip your rear bumper 1/4 at an expedited rate. Should fit and look good though.

measuring rim on my rear is 11" or should I be looking for some stamped numbers ,aftermarket bullet deep dish

[Laffs]

Most likely they an advertised 10'' wide (think its the width between the bead, not overall width)

Many times they will have width, diameter and offset stamped behind a spoke.
