Et51 offset alloys on superb mk2 l&k?

[Adamabz]

Hi has any body fitted et51 offset alloys on a mk2 L&K. I think the originals are et45. Just wondering if I would need spacers? Cheers

No idea, since you haven't bothered to tell us what width either set of wheels are,

You can see from the Skoda parts catalogue that the following rims are used on the Superb MK2.

 

7Jx16 ET45 205/55R16

7.5Jx17 ET49 225/45R17

7.5Jx18 ET46 225/40R18

 

The minimum thickness hubcentric wheel spacers are 10mm, so that would effectively change an ET51 offset to ET41. However, ET51 is only 2mm more than ET49...so perhaps stick with the ET51 offset.

If you mean 7.5Jx18 ET51 5/112 57.1 alloy rims, then a slightly oversize 235/40R18 should help to protect the rim from kerbing damage.

 

With the ET51 offset being 5mm more than the standard 18" ET46 offset, the slightly wider 235/40R18 would help to fill the wheelarches rather than have a slightly sunken look.

 

One of the downsides of the 235/40R18 tyre size is that it generally costs more than the common 225/45R17 and 225/40R18 tyre sizes.

Thanks for the reply. I have 225 40 18 original L&K alloys on the car which are et45. I was just wondering if the same size alloy but with an et51 would cause any issues. I.e rubbing struts etc. I have seen a set for sale and was just before I commit to buy them! Cheers

All of the 7.5Jx18 alloy rims shown in the Skoda parts catalogue for the Superb MK2 have an offset of ET46, not ET45.

 

What is the OEM part number of the rims? Perhaps 3T0601025Q HA7 or 3T0601025QA 8Z8

 

The OEM part number of the rim is cast into the back of the rim.
