VT Berlina Sedan
Hey guys,
I have a 1997 VT Berlina which has 15" Alloys on it at the moment.
Im looking for new rims but I just got new tyres so i need to keep it 15" for now.
Now i understand the size on mine is 205/65/15
so would i have to get that exactly or would 205/60/15 or 205/70/15 fit?
Cheers.
PS that is the size on the wheel (205/65/15)

yes 60 and 70 series tyres will both fit. But why would you change away from the 205/ 65 /15?

You have a series 2 VX i see. VT's have camber problems, the bigger you go with wheels, the worse it gets.
The 60 and 70 (middle number) is the sidewall thickness is it not?, so any variance in that isn't the problem, just variance in the first and last numbers is where the problem will arise.

********
As far as sizes on the tyre is concerned the 60 and 70 (middle number) is the "aspect ratio" which is the relationship between width and height. To get the same height, that is, overall diameter, which equals the same revolutions per kilometer, and also speedo reading, the equivalent to 205/65x15 would require 195/70x15 or 215/60x15.

As for the size on the wheel itself, the usual designation should be 6.00J(or K)15,
6.50J(or K)15, 7.00J (or K)15 etc.. The 6.00 is obviously the rim width, the 15 is equally obviously the rim diameter, and the J or K (on steel wheels) defines the gauge or thickness of the metal of the rim. The higher the letter in the alphabet means the thicker (stronger) rim.

On most Alloy Rims that I have seen, the letter is dropped leaving the designation as 6.00X15, 6.50X15 etc..

However, I have never seen any wheel (Steel or Alloy), where the specific tyre size, as in 206/65X15, has been used to designate the wheel size. I am open to correction on this matter if someone can quote specific instances, photographic proof would obviously put me right on the spot.

Hope this helps somebody along the way.
