Tyre Profile Rules in VIC

[mattsrea]

Hey guys i'm from Sydney moving to Melbourne soon and was wondering if i'd pass VICRoads roadworthy test with my new tyres i've got on. The new specs are: 195/50/15" and my stock ones are 185/60/14.

whats the load and speed ratings?

but it depends how much the rolling diameter has changed from standard, if memory serves me correctly i think its +/- 15mm

whats the load and speed ratings?

I dunno the speed ratings and load but does 82V on new tyres help? And i can't remember my stock ones.

82 is the load rating and V is the speed rating.

sounds like you looked at the tyre placard, it should also included recommended tyre pressure for standard tyres and a few other things.

size wise they are fine, load rating is the same so thats fine, the speed rating on the 15s - V , is greater than that of the standard tyres - H so that will be fine, so you should be fine.

this link is useful when looking at speed & load ratings of tyres to work out what ones you should get - http://www.bobjane.com.au/load-speed-ratings.html


one more question, how wide are your standard rims and how wide are your 15s? i think (but dont quote me on this) youre not meant to go more than 2" wider than standard rim width (also not sure if its what come standard on ur car or what was the widest for the series of car (if that makes sense))

Oh ok thanks for the help have a sense of relief for now lol. And the stock rim size im not sure off, i'll check it out tomorrow and let u know but my 15s rim size is 15x8 with PCD of 4/100.

Some shops will pass the 8", some won't. I'd just swap back to stock for the test. The rule is 1" wider, or 25mm. Your stock rim is something like a 14x5.5

[Lukey]

it might say on the tyre placard what the stock rim width is.

but i got a feeling they will be too wide, and if your tyres are sticking out of the guards they will likely pick on that.

if you can id swap to stock rims to pass rwc then swap back

i thought it was 2"?

or am i think of the imaginary rule of 2" bigger in size? lol
