Trophy Tyre Question

Up until yesterday my tyres were as per the Tyre Guide in the sticky at the top of the page.......



195/45 Z R16 Goodyear Eagle F1 fit to 7J x 16 alloy wheel - FRONT only



215/40 Z R16 Goodyear Eagle F1 fit to 7J x 16 alloy wheel - REAR only





I've had to get 2 new front tyres and I asked them to fit the same tyres, however what I've got is 195/45 R16 (There's no "Z" in the name) and the tread is completely different.



Is this an issue? I've clearly paid for the 195/45 R16 so there's no problem there, I just want to double check that they're ok with the 215/40 Z R16's on the rear.



If they are ok, my pressures were also as per the guide.....



Normal driving conditions lbf/in bar
195/45 ZR16 (front) - 24 lbf/in ......... 1.7 bar

215/40 ZR16 (rear) - 36 lbf/in ......... 2.5 bar



Would that be the same with these tyres?



Thanks.
