Looking for a rim... and will they fit my P5?

[jessicacrowe12]

So this guy is trying to sell 3 18" rims. I am assuming they are no longer being made because I cannot easily find them. They are supposedly G-racing 18" chrome rims. Now, after looking around I think I understand that if I want 18 in rims I have to have 215/35/18 tires. Is this right? Also any ideas on where to find a rim like this?

I know they are 5 lug universal. I asked the guy to send me all the info on the inside of the tire and this is what he sent:

18x7 1/2 JJ
YHI 964
ET45

He wants $100 for the three matching tires plus the mismatching one(which i have no clue why i would want) I figure if i can find the fourth for a decent price It would be a good deal. Any ideas on where to look?

why would you but a set of mismatching rims? I understand if you bent one yourself and replaced it.

You are looking for 5x4.5" or 114.3mm. Not exactly sure what the 5 lug universal is, but it's usually 5x100 and 5x114.3, so you should be fine.

On the last note, I'm not exactly sure if 18" will fit, you may have to ask around. I've bought my car with 17" and they already look over sized compared to the car.
