If you overly worried then just use Ori size. Just few mm difference probably not exceeding 10mm. Won't die one la. If not why not just change smaller rims... You will have plenty of sizes to choose even better cheaper tires.
I suggest you read up what the numbers on the tire size means to reduce your worry

i don't think yo really read up on what those numbers mean on you tires.

again it is totally safe to put what ever xxx/yy/ Rzz. While x = plus minus 10. y = plus minus 5. A long as you stick with the same Rim size which is 17 inch in your case.

What is not safe is, how cheap/unbranded the tire is. or how you drive. if you drive slow... any ABC branded tires will work. Happy shopping then.
