yet another tyre profile query
« on: Oct 4, 2005, 11:31AM »
hey folks

the mrs get done over by our lovly friends at QLD transport.
she currently has 15inch wheels with a 65 profile tyre on it. now "aparently" this is 1cm too big, so does that mean she needs a 60 profile or a 55 profile?
cheers biarchs

But we miss you every day
And I'm bitter 'cause it's unfair
We'll be drinkin' in the sun
Playing music having fun
Cause one day I'll see you there

whats the width of the tire? you can work it out as the profile is a percentage of the width for example a 215/40/R17 (what i run) is 215 wide with a height of 86. as far as i know it. you can then work out what stock is and find out the overall diameter of them and compare the two...from memory youre only allowd 15mm either side of stock.

Nath, that miata.net page is linked all over car forums. This is probably the 4th time I've seen it on antrx.
