Hi

I've taken the plunge got hold of some Mercedes Alloys 16xJ7 ET 37 from a 320 CLK (P/N 208 401 01 02)( look like these https://e.allegroimg.com/original/0155c7/7dc84f0b4814a92248c0d0e685ae ). I'm hoping this is going to make the ride a bit smoother and reduce the being blow around the carriage way feeling.

 Three questions really:

 1. What tyres should I run on them, was thinking 205/60/16 as this matches the original 184/80/14 circumference   but reading around there is lots of variation being used, what's 'recommended' (I'm on a stock JX engine and 5 speed box)

 2. What bolt lengths should I be getting? the bolt hole is 24mm deep so my understanding is that i need:

  •  38-41mm bolts with radius nuts on the front ( might need to cut down the 43mm on  Brickwerks?)
  •  60mm studs on the rear cut down to ~49mm - will need to check once fitted, with radius nuts

 

3. No spaces needed as ET is < 39?

All input greatfully received

Thanks

Matt

Have a play with:


I'm running 205/65 R15 on my 15" rims to match the circumference of the factory 14" alloys (which were 205 wide too).  I woudn't go much wider with a JX as it already has a hard life as it is.

Thanks for the input

Looks like getting small radius bolts for Mec wheels on the front (from brickwerks at least) isn't possible so will have to do a stud conversion 

shopping list is looking like

10 x LONG WHEEL STUDS > 60MM [M14X1.5]
10 X CONVERSION STUD - M14X1.5 / 60MM
20 X WHEEL NUT - M14X1.5 / RADIUSED SEAT (R12) / CLOSED END / CHROME
1 X BEARING FIT AND STUD LOCK - 10ML

+ 4 shiny new tyres
