Guys & Gals,
I've got set of 19" 2 piece wheels which I'm keeping secretive until I mount them on
Timeless and boy will they look good when on
I need help however............ I bought them online via ebay and the seller was unsure of the ETs and what not so I took a leap of faith, bought them, got them refurbed and now since I'm looking to buy tires, I realised why all this info is so crucial.... yes it's my 1st time buying wheels so I know NOW, what I need to look for next time.
Anyways, since the wheels got refurbed, I can't quite make out the stamped info inside the wheel but from whatever little I can see,
I THINK it reads the following:
Fronts:
- 8.5j x 19"
- ET 40
Rears:
- 10j x 19"
- ET 40
Now.. From the measurements I have taken (following a step by step guide to work out the offset).. my findings are as follows:
Fronts:
- Overall Width = 240mm
- Centre Line = 120mm
- Backspace = 160mm
- Offset = Backspace - Centre Line = ET40
Rears:
- Overall Width = 280mm
- Centre Line = 140mm
- Backspace = 165mm
- Offset = Backspace - Centre Line = ET25
Question is... what do I go by? What I THINK I read on the reverse of the wheel (and it does look that rear ET = 40) OR what I have worked out using the traditional method?
Also, it may be handy to know I've got an E92 335D Pre LCI dropped on BC BR Coilovers. I can of course raise the car to avoid the rims catching the coilover etc.
Would I absolutely need spacers? I want a semi-aggressive kinda' stance so I'm going for a slight stretch of tyres.
Currently on OEM 230s (19") and fronts are 225/35/19 and rears are 255/30/19
I was thinking of 215/35/19 for Fronts.... and 255/30/19 rears? How will these go down with the spec give?
Lastly, is there ANY other way to find out what 'J' the rims are??
Many thanks in advance,
Sam
