Title: 235/40/18s on Stock GTI Rims Anyone doing it?
Post by: McDoof on July 12, 2017, 01:00:25 PM
As per the title.
I know there was some discussion around this a while ago but can't find the thread.
Is anyone running 235 wide tyres on their 18x7.5" rims?

I believe Hennie (Glidn) is.

I'm running 235 40 18 on stock wheels.
No issues at all. Tyre selection depending it can look a little bubble like.

I do have more sidewall movement now thou. but still very happy with ride and handling.

Are you running the N8000s on your GTI?

For all of 5 days yes.
No Nexen N-blue available for approx. 6-8 weeks

You getting a decent price?
Been quoted $1100 for a set of 4 N8000 with alignment. That is for the 225 40 18

Wow, that's almost Michelin pilot money right there.

If you need some great pricing on tyres you can always hit my mate at Tyre Tech (Chris Middlewick) and just tell him Arno sent you and he should quote you a decent price.

Post by: McDoof on August 21, 2017, 09:59:07 AM
Thanks Arno. Hennie said the same thing. Right now I am squeezing the last bit of life out of the RE002s just because they are suddenly so good in the dry. Probably because they are pretty close to semi slicks now.

Getting a set of Michelin PS4 235/40/18 fitted tomorrow. Chris @ Tyretech sorted out a good price

Awesome work. Just got two new tyres myself from Chris @ Tyretech on one car. Also a set of wheels from him for the other car.

So far so good
Definitely getting more power down to the tarmac now.

not too big ?

better traction due to new tyres or more contact patch ?

How are you finding them?

* Did you notice fuel economy decrease?
* Did you notice extra grip?
* Any difference in handling around corners?
* How far do the tyres stick out from the body - can you post some pictures please?

Thanks

Im considering a similiar setup which would involce the 235/40/18 tyres together with some new black rims and all the badges blacked out

Hennie - can you reccomend someone on the shore who can black out the badges and also repaint the gti's red calipers?

* Did you notice fuel economy decrease?
I can't comment on the fuel economy yet, but I imagine the real fuel consumption will be much the same. While there is a bit more rolling resistance from the wider rubber I imagine this would be offset by the slightly bigger rolling circumference.

* Did you notice extra grip?
Hell yes, much more grip getting off the line. I was wheel spinning the old tyres almost every time I pulled off.

* Any difference in handling around corners?
Not really, I never had any issues around corners before anyway, so still very grippy around corners. What I can say is that the ride is just a little less harsh. I don't notice the ripples in the road so much any more.

* How far do the tyres stick out from the body - can you post some pictures please?
They don't really stick out. The Michelin PS4 has a very square shoulder compared to the Bridgestone RE002 so at first glance they look more like what the stock 17s look like.
This is currently the only pic I have, the car is on a funny angle so the rear arch gap is bigger than it should be. And you get a nice twisted picture of what looks like my headless dog, about to eat one of my kids.

I have new OEM replica ED30 wheels if that's of any interest.

Regarding your query?
Absolutely - Go see Custom Coating on the shore.
They can do it all. Best part is they are extremely skilled in their profession.

Let him know I referred you. Should look after you a little better.

18 x7.5 reps ?

do you know the offset and weight ?

factory 18s are heavy, black paint probably makes them heavier.

These would be new rims

I'm leaning towards these https://dtm.co.nz/assets/Marlin/WEBW-NICESSENMB.jpg

OR these (Plus making them black): https://dtm.co.nz/assets/Marlin/WEBW-REVW5573BKF.jpg

The 2nd link is the OEM Clubsport S rims, but I can get replica's made

Or these replica golf r ones (again made black though): https://dtm.co.nz/assets/Marlin/WEBW-REVW5586.jpg

I'd just be adding the weight back on that I gained from replacing the heavy stock exhaust with the milltek one, I think its something like 15 or 20kg weight saving

Here is a mk5 golf with the replica clubsport s rims equiped, don't know what tyres are on there

Now imagine those rims but blacked out with newly painted racing red calipers - maybe its not as cool as it sounds in my head, but I get excited when I think about it..

I was going to re-paint my callipers but ended up just rubbing them with polishing compound. They came up good as new.

thats a pretty good result, unfortunately in addition to the dirt/fading my calipers also have chips in the paint and polishing won't fix that
Title: Re: 235/40/18s on Stock GTI Rims Anyone doing it?
Post by: Naekyr on October 12, 2017, 07:22:44 PM
Had this done, pics to follow

I think my wheels are extending slightly further than mcdoof's due to 18x8 rather than 18x7.5 rim

Hopefully I get used to the look, otherwise may look at some guard rolling, there is zero rubbing happening, just a visual personal preferance

But after some quick initial testing there is a big increase in grip - the previous tyres were PS3's with 6mm of tread left, these 235 PS4's are night and day, no more wheel spin, no more wheel hop and traction control light doesnt even come on from a hard pullaway in sport mode!

Basically it feels like GTI's should have come with 235 tyres to begin with

^^This^^
The amount of power that is actually delivered to the road now is in a different league. Not sure if it's the PS4s or just going up to 235s, but it's confidence inspiring.

First day driving to work - great tyres but with the radio off, they do produce a little more road noise, unsure if its down to the extra size or if its just PS4

Took the car out for a spirited drive from east Auckland out to the Hunuas over the weekend with 3 heavy people in the car including myself. I have noticed a few things.
1. The car is a bit more twitchy at speed than it was before. As in the every tiny little steering input translates into movement. Not a bad thing as such but took some getting used to.
2. When the car is loaded up and being driven hard I got a tiny bit of rubbing in the front left arch liner. Going through a corner that had a bump in it. Really only there where the arch liner bulges out for the fixing screw but still a bit of rubbing if given the right combination of corner, loading and speed.
3. Almost no torque steer compared to before. Still some but not much.

Haven't noticed any rubing but most i carry is a couple small sized people

Pics as promised but they are lazy pics and im late to the party - car is dirty and needs a clean again and some better angle and lighting for pics, found a few mint spots in auckland but need some nice clear sunset/night weather rather than this awful overcast weather of late

Ended up not painting the calipers although I did paint the rotors black as there was a little rust on them and black looks better than silver
For the calipers I took your advice mcdoof, just used some dragons breath and a tooth brush, then some polish by hand and finished with a ceramic coating

Now the paint, windows, trim, rims and calipers all have ceramic coating so they all get nice and shiny after a wash

you need to do the fender screw mod. Remove the screw at the top and push the fender liner to sit onto of the screw tab ;)
