It's not just about snow... better to think of them as cold-weather tyres. Different compound (more silicon usually), behaves better below ~7°C.

I've used them for a few winters now and they do make a big difference. This last week, I can really notice the stock P Zero triggering ABS very easily.

Good to know. My problem would be I don't have anywhere to store 4 19inch alloys.

I haven't ordered yet though so this might be a next year problem.

I'm going to have to do a bit of tidying up if I proceed... if only to hide them from SWMBO!
 
I did not find ET recommendation for the 18" rims, but the recommendation is published in the user manual, screenshot of whic can be found in the first post of this thread:

225/40-18 tyres have -10 mm in overall wheel diameter comparing to 235/35-19

minus 10 mm means minus 5 mm in the ground clearance (and this is in a vehicle with already tiny ground clearance!!! :eek:o_O )

makes little sense to me... esp. in countries that actually do have snowy winters

That is false. The height of the tire is a percentage of the width ;)

So
225/40-18 are 40% of 225 high. resulting in 90mm tirewall height
235/35-19 are 35% of 235 high. resulting in 82.25mm tirewall height

The tire height also includes the non visible part that sits inside the rim.

use a tool like www.willtheyfit.com for a decent comparison ;)

If hanging them in your garage is not an option, I bet there are some safe solutions to stack them and make a coffee table out of them, or maybe2 stacks of 2 rims for stools ;)

This is from the website you proposed:

Ride height -~5 mm

Right height is a result of smaller rim and taller tyre wall, which is still ~10mm smaller diameter so ~5 mm lower ride.

I saw that too, and since I have already issues with my garage ramp, I was considering 235/40 R18 as it is actually the closest wheel dimension to the stock 19"

Unfortunately I don't have a garage. I have a cupboard, if I can move some of my girlfriends shoes :p

Just look at the diagram above: 647 mm vs 637 mm ;)
 
Winter wheels mounted, they fit well to the car&color, love them:D
But i have to say that 18" look a bit small...or i just need to get used to it.
A wet dream if the Yamatos would be 19":cool:

18" wheels look just OK ;)
Personally prefer look when brake disc and c caliper fill wheels to the max.
Waiting for somebody to put 17" rims and 235/45-17 tyres on the N Performance :cool:



P.S. if you can go small, just do it!

For my taste 17" would be too small...even if they would fit. Think 18" are best compromise between look and handling. But i will go for low weight 19" for the summer.
Or stay with 18" if they convince me, not driven much with them yet :)

You could get the brakes from the Option pack, they fill even 20":D;)
 
I have been doing a lot of searching. I planned initially on getting 18" wheels and tires according to the manual recommendation. Living in Estonia, our winters can get quite snowy and icy. But availability of suitable wheels and tires is a bit of an issue. The German site with the nice complete sets won't ship here, the dealer is quoting €2700 for the 18" wheels of the non-performance i30N and a set of Michelins. Getting my own wheels and tires plus a TPMS set will run the same price as the sets from the German site, but with wheels that don't look as nice.

So I think I'll go the cheaper way of putting a set of good winter tires on my stock 19" wheels. I know it is not as optimal, but I don't drive that much to justify the higher costs of 18" wheels (think <800km a month).

Looking at the new Vredestein Wintrac Pro at the moment.
 
Intrance, living in Estonia and probably having friends that travel to Russia from time to time, for a ~1k EUR you can have an order-made set of nice 18" forged Russian wheels (with a custom ET that perfectly fit N)

Haha, maybe :p. My experience with Russian mechanics here so far has been less than positive so I’m kind of prejudiced against that. And it would still be €1000+tires+TPMS etc. A set of high quality cold weather tires or even the more serious Scandinavian type winter tire will be less than that.
 
Hopefully picking up my new winter wheels and tyres tomorrow, has anyone had issues fitting the old set in the back with the sway bar?
