Does it fit? (Wheels)

Does 8x18” wheels with Offset 46 fit octavia properly?

[inspectorman]

Inner clearance will be 4mm less; outer clearance will be 8mm further out.

7.5Jx18 ET48 is the standard specification for 18" OEM rims on the Octavia MK4, as you can see on "skoda eshop cz"

Yes. But still the question is. Will they fit without issues?

Probably. I can't imagine that the standard car with 225/45R18 tyres fitted to the standard 7.5Jx18 ET48 rims wouldn't have a few millimetres of clearance to spare.

 

It's not something that I would do, as the tyre sidewalls won't bulge out much on the wider 8J rims, ie. less rim protection from kerbing damage. The wider 8J rims will also make the sidewalls less flexible giving a harder ride.

 

I'm also not a fan of aftermarket alloy rims. If you need a replacement at some time in the future, it could be hard to find a replacement, expensive, or even unavailable.

 

Look how easy it is to search for a VAG rim. For example 8D0601025K as shown below. There's a huge advantage in being able to search for a VAG OEM part number.

 

Most aftermarket alloy rims are heavy. Sand cast aluminium is a weak material. Because it is weak, a lot of material is needed. Hence they tend to be a lot heavier than the steel equivalent in the same size.

 

If you like 225s, I would be looking at 225/55R16 fitted to 7Jx16 ET45 from the Superb MK2, Yeti, and many other VAG cars.

 

The 8D0601025K 7Jx16 ET45 5/112 57.1 alloy rims from the Audi A4/A6 (around the year 2000) are made from forged alloy, and are a lightweight but strong design. They weigh around 7.3kg each, whereas most 7.5Jx18 ET48 alloy rims weigh over 12kg each. That's a huge difference in unsprung weight.

Together with 225/55R16 tyres, the 7Jx16 ET45 rims would be far more comfortable than the stretched 225/45R18 tyres on 8J rims (or even the standard 7.5J rims).

 

Another problem with 225/45R18 tyres, is that they tend to be over-specified for the Octavia MK4. For example, Y-speed rated and XL (eXtra Load). This makes the tyre's sidewalls a lot stiffer and less flexible, resulting in a harder ride.

 

In the 225/55R16 tyre size, there are plenty of tyres available with a standard load index (ie. not XL) and a lower V-speed rating.

I can't find the weight for a 7Jx16 ET45 steel rim, but it will probably be similar to the 7.6kg weight of a 6.5Jx16 ET46 steel rim from the Octavia MK3 and Octavia MK4, ie. about 2kg lighter than a sand cast 16" alloy rim, and about 4kg lighter than a 18" sand cast alloy rim

This 19" alloy rim from the Superb MK3 weighs a whopping 14.4kg

Thanks for the detailed info. 
 

I did order 7.5” rims but the shop gave me 8” for some reason and claims that i’ve agreed on them. 
 

Summer wheels are 19” altairs (225/40/19) from skoda. Winters have to be 18”  .

I dont mind the harsh ride, since i can tune it with DCC. 

 

But yeah. I’m was thinking that new proper size wheel set would be 500€ more now. If the 8” wide wheels just fit (with the 225/45/18) i’ll keep it to save a big buck. They are Dezent TR’s. 
 

Also i did notice that they weighted about as much as my previous 16” wheels. So pain is no problem. Pretty sure tje original 19” altairs weigh more.

According to the dezent-wheels.com website, the Dezent TR's are available in 7.5Jx18 with offsets of 38, 40, 42, 44, 46, 48, 49, 51, 53 and 8Jx18 with offsets of 30, 35, 38, 39, 43, 44, 46, 48 and many other sizes.

 

So the standard 7.5Jx18 ET48 is available.

They'll fit fine. I've got 18x8 +40 on my 21 vRS with room to spare.

Okies, thanks.

[TheUltraRunner]

You will be fine. For example, 8.5x19 ET45 fits nice. So yours will fit also without any issues.
