What size tyres are required???

[ITSACLK320]

What size tyres do I need for these wheels....

2X 7.5J X 17 ET 37

2X8.5J X 17 ET 30

I think it could be...

225/45/R17

245/40/R17

But I am unsure.

Does anybody know of a website that gives this info.

Thanks

Thanks for the replies.

What does 7.5J X 17 ET 37 actually mean?

And is it the 225/45/R17 that will go on this rim?

Thanks again

7.5 is the wheel width in inches
J is to do with the shape of the lip or rim edge or something like that
17 is the wheel diameter in inches
ET 37 is the wheel offset in mm

225's go on the 7.5" wheel & 245's on the 8.5" wheel

Hi,
These tyre sizes are what i have on the C43 but i have as yet not found the recommended tyre pressures in the handbook and the sticker on the door shut/petrol cap flap refers to 215 width tyres. Any suggestions? many thanks.

Mine goes from 30 Front, 30 Rear to 38 Front, 44 Rear
depending on speed and load.
