2nd gen 2011 Mazda 3 with speed rims

[hitable]

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!

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?
