Hi Canadian and blackfusion.
Yes, he "asked if they would fit". However, even though he does not specifically ask, I believe it is safe to assume that he would also like to know whether it is "safest or smartest" to use them, to which even you guys admit the answer is no. I don't believe he only wants to know if they can be squeezed on, forget about the consequences.
If you reread my reply, I think it was very reasonable. I stated that the 5x115's will be able to be squeezed on, but that they are the wrong size and should not be used. That is what the experts say.
I then stated that he should call The Tire Rack, Discount Tire or a similar professional source where he can get expert
advice as to whether he should try fitting 5x115 wheels to our cars (which specifically take a 5x114.3). And if the experts state otherwise, then I was incorrect and he can use them.
I have now consulted with The Tire Rack and know the expert answer. Other than that, I don't see how it makes any sense for a bunch of us "non-experts" to debate it.
Once he consults with an expert source, hopefully he will post back and tell us what he found out.
