Tyre Size - Page 2

pimpdriver is right if you are going from 185/60x14 to a 15" rim you need 195/50x15, the 60 or 50 is the size of side wall of the tyre which is 60% or 50% of the width of the tyre

yes my mistake

what threw me was the fact the wheels he has were mine off the 100 typ43 and i had 185 65 14

forgot the coupe and 80 started off with a smaller 60 series tyre

thats why i sed 55 not 50s sorry

I am also sorry Micky. I just didn't want the guy to go and buy the wron Tyres.

185/60R14 is golf gti size and a popular upgrade is 15" rims with 195/50R15.

I'm using 205/50/15 on my R8's, but then the standard tyre size on the Cq is 195/60/14 so this is the closest match for mine. Have a tyre size calculator here on Excel..

195/55/15 are correct for a CQ as the it would have come oringinally with 195/60/14's the difference is as follows:

Difference in Diameter = 1.02%
Actual diameter change = 6mm

If you went for 195/50/15 series tyre then you would be 2.37% out and have 14mm smaller diameter.
