Mar. 23rd, 2004 03:56 pmTyre sizes
My tyres are 185/65/R14's
These numbers are: Width of tyre in mm
Aspect ratio height of the sidewall as a percentage of the width
Diameter of Rim in inches.
Now these measurements are enough to uniquely define the size of a tyre.
But does anyone else find it a little odd that the 'standard' measurements are mm, percentage, inches? I mean, what would have been so difficult to do 185/120/308 to keep the whole lot in mm?
I'm looking at replacing wheels at the same time. Whether I do that or not depends on whether my tyres remain above 1.6mm of tread for the next couple of weeks. Cos Direct Line won't insure me until I'm 25...
FWIW I'm thinking that either the TSW Zenon or Venom. Probably with Falken ZE512s and either in a 215/40/17Z or a 205/45/16V. (Oddly the 17" rims are almost exactly the same rolling radius with 215/40 tyres, where the 205/25/16s are about 1.5% smaller).
Which I go for depends mostly on price, and how much cash I have spare in a month. (Oh and how much overall damage this does to my cost of insurance, given that I have no NCD at the moment).
Oh well, maybe I'll get lucky and persuade various family members that that'd be a good birthday present. And then I can do all those My PRECIOUS dances.
