I am looking at some alloy rims spec 17 x 7.5 offset 35P the standard steel rims on the Caddy are stamped 6J 1542 ET 47 (what ever that means 🤪)
What's your educated opinion on wether they will fit? I can't test them as they are a long way from home, yes I am aware that the diameter is different.
Thanks in anticipation

Will sit approx 1.5" further out from current wheels & 1" further in on the inside, go full lock,both ways, allow for that much extra, ideally more, think about up/down movement of the shocks too & if everything clears you should be fine 🙂
Oh and your track increase is just on legal limits without engineering paperwork, in qld at least

I can only guess at the diameter of your current wheels, it looks like they are 15" x 6" with a ET of 47MM, the new wheel with a et of 35MM will only move the inside of the rim in approxamatly 7MM, the problem will be the rim on the outside of will move approxamatly 31MM, you will have to check that you have enough clearence on the suspension and mudguard side. all depends on the tyre size you are going to run also. ckeck the links as follows.

Google wheel offset calculators, tyre/tire size calculators for a visual of it, 1010tires & miata forums are the best I've found

Dont forget the centre bore size, most modern cars have the lip on the face of the hub.
Your new wheels will have to have the same size centre bore or they wont fit

Cool, thanks heaps, just need to check the centre bore, although there seems to be a diference between measurements vwo60 has given and those given by STIDUB, at least I understand what it means and know what to look for now, yes vwo60, the existing are 15" so obviously I'll need to go for a lower profile tyre, that should improve the already rather harsh ride 🙅😀, also I'd beter check the allowable track increase here in the nanny state of NSW. great links BTW, thanks again.

Hi Don,
Unfortunately the opposite happens, the lower the profile of the tyre and less sidewall, the more the tyre loses it's cushioning ability as there's not as much give so you tend to feel bumps and ruts in the road more.
well on rougher surfaces anyway, normal road surfaces are not a problem.
Its more cornering where lower profile tyres really shine.

As I'm feeling lazy today would you be so kind as to remind me what track width change is allowable in QLD?

madness is in the eye of the beholder 👍

Track width is measured from the centre of the tyre, and that only increases the track by 1/2 inch if you measure from the centre of the tyre. So well within the 25mm allowable increase.
