Re: Tires / tyres
215/45R17 will foul the spring perch of the stock strut. I wasn’t game enough to bash a suspension part upwards to fit cheaper tyres.

Re: Tires / tyres
I ran 45 profiles for a couple years. One side cleared ok while the other hit the spring perch. I simply used a hydraulic jack to raise the perch a few mm's and problem was sorted. No bashing required.Hmm that's a good point about the stock struts point - Thanks for that.
I'll probably end up the 45 profile for the fronts as it's not 'Buy 1 Get 1 Half Price' on the 40 profile - So it's $200 more to a get a pair of 45 profile.
I'll risk the 45 profile and update when I eventually get it sorted
Doesn't have any effect on suspension and I preferred the 45's as having larger profile handled the road bumps better. Low profile tyres can be very harsh riding. Pic below of the clearance before I tweeked perch.

Re: Tires / tyres
My main reason for asking to try fit a rather interesting wheel combo using smallish tyres on stock suspension with the future of going with RS*R lowing springs.
17x8.5+5 and 17x8.75+20.
I think I just opened the flood gates!!
PS, not my car.

Re: Tires / tyres
Is the +5 on the front or the rear? That's really low offset, so I don't see a reason why it would hit the suspension - But the guard would be another matter.
https://91mr2.com/wheel-and-tire-calculator/
By this website - You're 27mm out of flush on rear (Assuming +5 is on the rear) and 22 out from flush on the front.
On the other hand, if the +5 was on the front, your'e 37mm out from flush on the front, but 12mm on the rear.
This is assuming the classic 215 and 235 tyre combo. Tyres won't change the flushness of the wheel, but you can tuck it in.

Re: Tires / tyres
Thanks for this. l was thinking the same thing about the road bumps - I'll probably invest in some good comfy tyres actually.
I've been warned by a few people now that RE003s do not last as long compared to any other tyre in the segment.
Down to not affording tyres at the moment - I'm gonna hold out to see if anyone does any 'Black Friday' sales late november, I know Hyper Drive did last year. Maybe I'll catch Eagle F1s or Pilot Sport 4s on sale.

Re: Tires / tyres
Don't get me wrong, I know the flush fitment for an SW20 but that doesn't always take into account the camber OR tyre stretch. With an 8+35 and 9+35 being the recognised 'flush' but no specified camber setting we can go from there.GlanzaAtHeart wrote: ↑Tue Oct 27, 2020 10:25 pm

I use www.willtheyfit.com as it shows the approximate tyre shoulder position for the tyre being stretched or otherwise so you can compare a tyre size and wheel size.
So if we compare my 17x8+37 with a 215/40R17 to the 17x8.5+5 with the same 215/40R17 tyre you get this. Add in a whole lot of camber, which you will struggle to do on stock struts even with the smallest camber bolts, it's going to be very hard to fit them.
https://www.willtheyfit.com/index.php?w ... &offset2=5
Then comparing my 17x9+29 wit ha 245/40R17 to a 17x8.75+20 with a 235/40R17 you get this. Add camber and it should fit fine. It's barely different to mine.

Re: Tires / tyres
I've run the Eagle F1's and didn't think much of them. They were ok but not as good as other tyres that cost 1/2 as much. Probably one of the best economical tyres in my view are the Neuton Sports or Nt5000. I've run a set on my MR2 and Audi TT and they perform very well and seem to last the distance.Down to not affording tyres at the moment - I'm gonna hold out to see if anyone does any 'Black Friday' sales late november, I know Hyper Drive did last year. Maybe I'll catch Eagle F1s or Pilot Sport 4s on sale.

Re: Tires / tyres
Interesting - Were they the Directionals or the Asymmetrics? I heard there is a big difference. I did a bit of research and apparently the Eagle F1s perform better than Pilot Sport 4 -https://www.youtube.com/watch?v=2_utfLr ... yreReviewsBenckj wrote: ↑Wed Oct 28, 2020 8:44 amI've run the Eagle F1's and didn't think much of them.

Re: Tires / tyres
I'd definitely want a cheaper front rubber in 215/40 than a more expensive one in 215/45 for the reasons Al mentioned, it's just gonna be a squeeze. As long as your rear rubber is wider and better, you'll likely just get understeer in the dry and rain without the back coming around

Re: Tires / tyres
Yeah Ive been wondering this as I run 225/50/16 on the rear of my ZZW30 and can feel it slipping slightly in corners, both tyres have a good 4mm of even tread. My other thoughts around possible cause would be in that ive removed quite a few factory pieces of the car and thinking that the spring rate is now not enough to keep the tyres pressed to the road if that makes any sense. I have considered replacing the rear struts with KYB`s but ultimately would prefer coil overs for more adjustment as required just there are none available in NZ due to the covid stuff. Alternatively I could try A Yokohama of same size which are not a pricey as the Potenza $300 each.GlanzaAtHeart wrote: ↑Tue Oct 27, 2020 10:41 pm

Re: Tires / tyres
I would expect RE003s of that size to be a bit under 200$ each. Maybe try ringing a different tyre shop. Tyres mostly just act as multiple on the amount of mechanical grip. There's normally plenty in the rear of a zzw30. What's the proportional amount of weight you've removed from the back? That should be the proportion you go lower with the spring rate (lower weight lower spring rate). You could also increase the front spring rate if you'd prefer a stiffer car overall.001SPYDER wrote: ↑Sat Oct 31, 2020 8:36 amYeah Ive been wondering this as I run 225/50/16 on the rear of my ZZW30 and can feel it slipping slightly in corners, both tyres have a good 4mm of even tread.

Re: Tires / tyres
Hey people. For the factory 15” wheels for the SW20, I think there’s just two sizes available of the RE003s (195/50 and 205/55). Is this combo possible to run? Or would this be way off base?

Re: Tires / tyres
It's better than no with difference, but not great, probably still the best at the price point with 3 for 4?
You could go 195+225 in R888 or AD048 or AD050 @ 1000-2000$ with reduced wet weather performance.

Re: Tires / tyres
If there’s a good balance somewhere between price and performance that’d be ideal. I don’t really think I need anything too up there, considering I’ve now been pretty much daily driving on mismatched cheap tyres for a year and a half with zero problems (read: I’m a grandma). I just want something at least halfway decent that can go on the 15s.
