Hi all....
I've got a Ford Mustang V6 2007 with BF Goodrich 215/65/16 wheels...and I've bought 4 new BF Goodrich (in Ebay from a GT) 235/50/18.
Do you know if I'll find some problem using these wheels on my car?
Do I need anything?
And, last thing, but not less important, which pressure do I have to use?
Thanks.

You got new tires and rims, right? Cuz those 235/50/r18 won't work on 16" rims... But if you're just comparing tires you will be fine. The new tires are only .25" bigger diam. Max pressure for BF goodrich tires seems to be 45-50 psi, so I'd recommend 35-40 psi.

Yes, I've got 18 rims, all come together....
But, what's psi? I come from spain and here we have different messure, I think...

PSI = pounds per square inch (lb/in^2)
You are probably used to N/m^2 = Pa = Pascals
So, since 1 psi = 6894.8 Pa, you are looking at 241317-275790 Pa or 241-276 kPa. Sound more familiar?

Yes, for sure.....
We use 2.4, 2.8.....don't use decimals....
Thank you very much for your help.....
