Those tires were meant to be on our Bonne'*.
255 50 R 17 size is the same diameter as the stock tire but 3/4" wider which really only 3/8" wider on either side of the wheel.
The drag tires I use are 255 50 R 16. The contact patch width is greater on these tires than my Potenza 255 50 R 17. 9 1/2" vs 8 1/2".
After running with them for a year now, they have never contacted inside the wheelwells. Just a very slight brushing about 1 square inch on the lower inside plastic shield.
You will absolutely LOVE them in the wet and in the dry they will punish you.
