Arch rolling in Plymouth

[Icywalts]

I want to fit my new wheels to my car but they are wider then the cyclones that are standard on the car.. These gutmanns are 7js and they do poke just a touch from the arch. Because of the height of the car I know I will have to go for a lower profile tyre with some stretch to squeeze them in. Does anyone have any ideas on this? Would rolling the arch be worth it or not? Has anyone else had a similar experience?

   

   

   

Advice would be appreciated thank you.
