that reply explains it all.
read the FAQs and it will explain all.
the first number, 185, 195, 205 is the width of the tyre. So that is completely dependant on what wheel you go for, most probably 205 on a 7J wheel.
The next is the side wall ratio. it is a percentage, so 65, is 65% of the wheel face, if you want to match the VTR wheels when the rim is obviously bigger this number will have to be lower, 40 at most I think, might be able to squeeze 45s but they are tight on 16s so not sure, espcially with it being lowered.
last number is obviously the rim size.
hope i havent lost you with that reply.
