2nd gen 2011 Mazda 3 with speed rims

Hey guys, long story short, my stock tires are starting to go, I need new tires but because of tuition for university I am short on cash, my buddy gave me his 11 mzspeed stock rims, my other buddy has a set of Dunlop SP 600 from his 11 sti he said I could take. I have 2 separate questions.
1) Will the speed rim fit on my 3 (speed stock tire = 225/40) - and I know the bolt pattern fits what I mean to ask is will it cause rubbing anywhere
and
2) If I am able to get the 245/40 tires on the 18-7.5 speed rims, would that cause a lot of issues? Such as rubbing or what not

I know I AM NOT SUPPOSED TO do #2 but I only need them to last me through this summer, and trust me, I would not be asking about this if I had any other solution. My car is @ stock setting 2011 GT hatch. Any input would be appreciated! Thank you! :bang:bang:bang:bang:bang

1) Speed rims will fit on a 3 just fine
2) Eh, that's a bit meaty. I had 245/40 on 18x8 before and it rubbed (with spacers in the rear) but otherwise was just fine. Unnecessarily wide though haha maybe put it out there for trades?

1. Yup it will fit fine, same bolt pattern - 5x114.3
2. I wouldnt put that tires, get 225/40/18
