Like you, I have Fulda Y2000 185/70 VR 15 tyres on my ES and they have given excellent service, I didn't know they were no longer available for when I need to replace mine.
My understanding of tyre sidewall sizing is:
185 - the tyre width in mm., 70 - the aspect ratio or sidewall depth as a % of the tyre width, VR - the tyre's speed rating, 15 - the wheel rim radius in inches. No doubt someone will correct me if I'm incorrect with any of these.
On that basis, and to supplement the information given by Ron on the rolling circumference difference which is negligible at 2%, I don't imagine a 10mm overall width difference between 185 and 195 is going to cause any problems with the tyre sidewall fouling any suspension components as only 5mm will be on the inside edge.
Or have a look here, lots of reasonably priced 185/65 R15 tyres which would fit our cars without problem.
