ISTR 60 is the sidewall height in percentage so 60/100 x 185 = 111mm, but I don't know how much accuracy there is with these measurements.

MK2 XR2 original wheels have 185/60/13 tyres. 185 is the tyre width in mm 60 is the side wall height in mm 13 is the wheel size in inches I changed to 165/60/14 MK3 Fiesta steel wheels This means the speedo will over-read by 1 mph. Its the closest I could get at the time. I currently have a MK4 Fiesta (parts bin) which is 185/55/14 When these go onto the Q it should under-read by 1 mph, therefore taking me back to MK2 XR2 again.

A good suggestion Steve, will investigate. Was considering using it as a planter for my petunias. I noted that the pepperpot is a 6J rim and it has a 185/60 R13 tyre on, the current fitted road wheels are 6J's with 165/70 R13 tyres. I am assuming that there is an extra 2cm on the diameter of the wheels from what the xr2 had, so does that mean my speedo is under-reading? Must check it next time I go through one of those "check your speed" signs. Another dumb question is since both types of rim are 6J and the tyres have different tread widths, when the time comes to change all the tyres I could go for 185s? Rob, I was looking at 14" rims with 185/55 R14 tyres, the thinking being that the diameter should be correct and not a drastic effect on the ride. I hear that going for a lower profile tyre can make the ride harsher. Just thinking of my back! Thanks all.
