Alloy wheel size question - dxp55
I have a alloy wheel which is 17" diam and 7.5" from inner to outer rim edges -- would this be classed as a 17x 7.5j ??? - also where can I find a tyre size calculator for this wheel - alloy wheel center's just quote a tyre to rim diam size you input. - my web searching ability is not great and I get frustrated that something that seems simple never comes up with an answer.

Thanks.

Thanks for that --- another question for wheel and tyre men - our car has 195-45 x16 tyres on with rim protectors - looking at tyres it seem they are not wide enough for the rims - from the edge of rim protector the tyre walls are leaning in towards the tread - as though they are a size to small -- according to the link 195 tyres will fit a rim width of 6.5" to 8" (these are 7.5" ) inputting 205 tyres the rim widths are from 7" to 8.5" - The old Yaris had 195 same make tyres and the sidewalls were almost vertical from rim protector - I didn't measure the rims on Yaris but will do when I can get to new owner. -- I have also seen same thing on a mates A4 - he bought a set of alloys with new tyres and they looked like they were a size to small - - - would next size tyres up improve road holding and handling or am I just been too picky

Has anyone else noticed this on their cars.

Thanks.
