[urq] tires and premature ageing

[Martin Pajak]

Hi Lono,

Compared to the original '83 size which is 205/60 15, Tony is correct.
Tire size was year, not wheel size specific.  Up to '83 205/60 15 and '84
and up 215/50 15.

http://www.1010tires.com/Tools/Tire-Size-Calculator/205-60R15/225-50R15/215-
60R15

So in reality your '83 speedometer should actually read faster with the
225/50 15.

Hope this helps.

I'm following this thread with interest, because sooner or later I will need
to replace the 225/50x15 Kuhmos that I have on 8J Ronals on my 83 Urq.

I was confused by Tony's comment.  If the factory recommend size for the Urq
8J is 215/50x15 how can the 225/50x15 be undersized?  If nothing else it
would be oversize.  It does affect my speedometer to show a lower speed than
what I'm actually traveling at.  Am I missing something?
