hi all
i just buy a rim..
13", 6.5J, PCD114
the thing is i dono the offset

I tried to measure it myself,
the whole width of the rim is 19cm
and the backspace of the rim is about 9.5cm
but my measurement not so accurate
I think the rim should be around offset -5 to 5.

so just like to ask everyone here.. can the rim fit my B310.

Thanks in advance.

Unknown. Since you have bought the rim, remove a wheel from B310 and try it.

B310 wheel is:
* 12" x 4" with 30mm backspace
or
* 13" x 4.5" with 30mm backspace
or
* 13" x 5" with 25mm backspace

actually, my problem is,
my car is now fitted with 1.5 inch spacer,
which is unable to take out, unless i break the spacer,

so maybe try it with the spacer on and if i sticks out by less than 1.5 inch and has more than 1.5 inch clearance on the inside you can take the spacer off and it should fit. also try turning the wheel and see how much extra clearance you'll need etc. but it should be simple enough to figure out.
