cant tell from the pic if they're the classic 3 spoke(wont fit) or the p38 three spoke(will fit).Is it an ebay ad or similar?
that style of alloy is on both the classic and the p38 so would not be able to know from looking at the pic.
Assuming you had 255/55x18's originally, to maintain the same diameter you'll need 255/65x16'sIf they fit, what tyre size do I need? the wheel are 16" and the ones on the car now are 18"
Although both very very similar, there are slight differences between the two. I'm pretty sure the ones in the pic are the P38 version.that style of alloy is on both the classic and the p38 so would not be able to know from looking at the pic.
