I've been lurking around the multiple tyre threads for some time. The time is nearly here for me to renew the current tyres with something more comfortable, but not spoiling the handling. I'm potentially looking to replace-
OEM 195/40/R17 Side wall height 78mm
With
PS4 195/45/R17 Side wall height 88mm

As yet I've not seen this done (hence the new thread). To put this into perspective the side wall height on a golf with 18" wheels 90mm, so this isn't so crazy and shouldn't throw the speedo out too much (+2mph @ 70mph). I had considered slightly wider tyres (205/40/R17) on the fronts, but I'm leaning towards keeping them all the same. The PS4 is widely viewed as a comfortable tyre. People have gone with higher profile tires and not had any rubbing, so this shouldn't be a showstopper.

Anyone done this before with this size or tried staggered tyres sizes?

I assume the crosscilmate 2's are width 205 x 45. That must be very comfortable. Just a shame the roads aren't in a decent state to start with.

Looking at the 2022 tire test results, the more comfortable tyres loose some free and understeer more. So I guess that is the trade off, but not sure how much of this handling trade off you'd notice in the uk roads between the decent tyres......Whatever I go with I'll update with my thoughts.

Like many of you I watched the latest Volkswizard video. That car was on 16's (eibach pro st s, like mine) and I did notice a bit of a bump in the ride at one point in the video, I think due to a change in the level of the road.
I think with the limited suspension travel, lightness and SWB there's only so far we can go with comfort on UK roads....even on 16's. On the flip side, it's fantastic in the twistes. Very neutral and lots of fun.
I'm still mulling over what yo do, but from all the views it's clear it will only improve😀

What's 6 weeks compared to 2 years of covid19 😉
Having slept on it I've decided to go for the oz 17" wheels....as long as the delivery doesn't get too silly.
As the wheels are wider (7"), now the question will be....
205x40x17 ...82mm sidewall or
215x40x17 ...86mm sidewall
🤣🤣🤣 I think I'll have lots of time to sleep on it!

I believe the 205’s will look very slightly stretched on 17x7 will they not? The 215 will be a bit more square but not sure on the impact it’d have on the speedo?
Hi Frostliess, I'm enjoying your mod journey.

The pictures I've seen with those wheels are with the 205's. They look fine, similar to 195's on the Oswalds. With the 215 you'd get extra rim protection, but there's a limited tyre choice...the speedo should still under read very slightly.

Just a long wait now!

Cheers all. I'm tempted with pilot sports, only as I know them and know that they are on the softer side. But a cheaper tyre is not a bad idea.....there's soooo much grip with these light cars!

View attachment 9567 These could be an option lots of people really rare them and you can't argue at that price!
Thanks for the links, some good price tyres there👍
215 seems the one to go for on a 7" wheel👍
Assy6 as well.....with the older generation asymmetric's and ps4 I couldn't really tell much difference on a golf (18")....ride and handling, so similar.

Good points.
I think what I'll do (in nice weather) is gaffer tape cable (or something...) to the inside of the current front wheel /tyre. I can gauge the amount of space and go from there. It will all work out👍

I've just called CLP automotive (wheel supplier) to double check the order. He expects the wheels to be shipped in the next week! I asked about tires...and guess what, he has a lowered up gti and has gone through ride experiences etc. He says that the most popular tyre choice for that size of wheel is 205x40. I asked about the 215 option and he'd be concerned about catching if spaced outwards - potentially on the outside (offset and larger diameter). I will go with the recommendation, probably with PS5's😀

This post deserves repeating. Particularly re aquaplaning. Remember even the GTi barely weighs a tonne. Each increase in tyre width, for a given pattern and set of road conditions, reduces the speed at which control will be lost.
I can only agree with these posts. There are plenty of people happy with 205 width tyres and I'll be going with that recommendation. I assume 215 would be ok, but it's an assumption. I'm staying away as it seemlikely to rub

If there was a narrower wheel option, then personally I would have probably gone for it (thinking of mk2 GTI,s etc) but they start at 7" wide...I guess wider is more popularthese days😄

Thinking about it.....safety wise it should be far superior than what's on there at present - night and day, no question. It will be an OEM fitting wheel, slightly different offset (less than most wheel spacers), with a far superior tyre (regarding its performance in all conditions), with an increased wall height and lighter wheel, meaning an improved ability to absorb road imperfections safely. The speedo will still be within tolerance. I will be letting my insurers know👍

Thank you for this. It's good to see you're trying something different. I expect I'll probably be going with the alround option of PS5 on all 4 corners. I have eibach coilovers fitted and I'm finding the car very well balanced, so for me I think I'll try this first, but I did consider mixing the tyres front to back.
Stage 2 must be fantastic is this little light car.....one day!
