VWW Official MKIV Wheel Q&A

[caputo9]

Hey guys just a bit of a question regarding tyre size and profile affecting my speedo.

Im running 17" Denvers on my mk4 with 215/40 on the front and 215/45 on the rear.
I purchased my wheels with these tyres and still have above 80% tread on them.
With this comes error with my speedo and im not 100% sure on what tyres i need to correct this.
My speedo is about 10km's out with an app i have on my phone and im usually sitting on 70km/h with 60km/h traffic. (10km/h slower).

Its rather annoying always having to estimate my speed and was wondering what suggestions you guys have?
If i was to get 215/45's on the front will this fix this issue or only make a small difference?

Cheers

215/45 Will be much better,
I run them all round but still close to 10% out.
Even stock 225/45/17 will be 7-8% out

Thanks Dylan! looks like my next investment will be some tyres haha and hopefully i can sell my others off

OK!
Whats the general opinion on using adapters to change the stud pattern on a Mk4?
I understand adapters and spacers are possibly dangerous and very illegal so no need to comment on that.

I want some wheels for my Bora and am currently looking at the second hand market but there is not a lot for my car.
How popular is fitting 57.1 VW > BMW/Holden 5x120 or 5x130 Porsche adapters?

I am ssuming most people would probably go for the obvious 5x100 > 5x112 VW conversion but i would like to try a few odd wheels.
No doubt, i will become a wheel whore so i do not mind going through a few sets.

They are illegal in aus, your car will he unroadworthy and insurance may be void if you were involved in an accident . Dangerous can be put down to incorrect use and poor product.
Someone filling a car with fuel is dangerous if done incorrectly, same applies.

Bmw and Holden is 5x120 (unless you go to older makes which can be 4x100 for bmw).
You will need to keep centre bore size, bolt/nut seat type, and bolt/stud length in mind.

Can run anything, 5x112 is more common as it's a oem option.

Thanks for the info Dylan.

I think i might just pick up a supercheap set of rims in the correct stud pattern and offset and start saving for some custom order Simmons FR18's.

How wide can you go on the back of a Bora without stretching the tire too much?
For example, a 9" wheel with a 245/40/18? Would 25et be about?

Just thinking out loud now lol. If i am way off, let me know

[trickysimon]

Don't buy fakes/replicas.

Don't buy fakes/replicas.

I'm assuming you are referring to Simmons here? Or just wheels in general?
I don't mind my cheap as possible wheels to be no name rims and i don't hink i would buy replica wheels of any sort.

In regards to the Simmons, my plan is to get some 18x8 front & 18x9"'s or 10"'s rear directly from Simmons. Not cheap though

Can put certain brand 225/40 on 9s and it's fine.
Depends on size. Can fit 265s on the back if you don't mind having a bit of space above the tyre. Fuzion and trickysimon have done that.

As for the new fr, they are now all single piece rubbish i believe. try to find some older ones from when they were actually made by Simmons, not tempe

Yeah i don't mind having space above the tire. It is actually how i would prefer it with the road conditions up here.

So Simmons are not Simmons anymore? No more 3 piece rims?
Tempe make them now? So they are made from second hand melted down Chinese alloy? Wassup with that?!

So if i can find the "old" style centers, can i get them rebuilt and resized in the "old" way?
