Wheels and tire size help

[itbejack]

I need some help as I do not know a lot about rims and tires...

OK I am going to purchase a set of Work Wheels VS-MX off someone...The size is 18x7.5 the bolt pattern is 5x114.3, came off 99 Eclipse gs-t. Offset is +45
I have a 2003 accord v6 coupe...and his tires are nitto 555.
The problem is two of his tires are 235/40/18 and the other two are 225/40/18...He did this becuase of his turbo...
My question is how should I set up these tires on my car since they are different size...Moreover, which ones should go in the front which ones in rear? I checked a speedo calucator and I will be off by liek 1~2% but how would I calculate since tires are differnt size? Please help
Will this rub agasint my car, it is on stock springs and all...will the 45 offset make wheels stick out a lot? or not at all?

Just make sure that the wheels are all the same size for all four. If they are, for the time being, you could stick the 235 tires in the back and the 225 in the front. Then when you get the cash for it, get 4 new tires, all the same size.

45 is a good offset. Mine are 18x7.5, 45 offset, they are pretty flush, just a bit inside the wheel well. 235 is a bit wide, but you can probably get away with it for now. Just get 225/40 when you replace them, you'll be golden.
