I have an 87 Carrera 3.2 with 18" rims.....on the weekend I noticed that one of the tires looked low on air. I read the sidewall of my Z rated Bridgestone's and it said max PSI was 51..so I "topped up" all 4 tires to 45 PSI.

Speaking with my neighbour he told me I was crazy as when tires heat up the PSI expands and I risk blowing a tire at high speed...

So I said okay- what should it be at at which point he told me to consult my owners manual.....unfortunately I have 18" aftermarket Victor Equipment Lemans rims not OEM fuchs so its not exactly covered in the manual- assuming I actually had one that is.

I know there are a few guys running the same rims as me on here so your advice would be greatly appreciated...

Thanks!
