What do you think guys... a 17x8" +40 offset on a lowered euro - will it work?

it'd be great to hear from a member that has this setup, thanks :thumbsup:

chris you will be stuggling as i have +45 with 18x8 and its tight.

thanks for the feedback guys.. albii, do your wheels come past the fenders or are they ok? I have a feeling i could just scrape by with the 40 offset (well hopefully anyway)

Chris it is a bad offset to run especially since you mentioned you want to run 235/45/17. If you look at a 225/45/17 tyre and a 235/45/17 side by side you will see the 235 is MASSIVE compared to the 225. Go to a tyre shop and you will see what I mean.

I am running 235/45/17 on a +48 and 7.5" - and at the front the tyre is flush (to the mm) with the width of the front fender. Your size of +40 will stick out another 1.4cm past the fender!! Trust me on this it is a bad size to buy. Anyone walking past will see the front sticks out - including cops.

You also need to factor that wildly changing the offset on a vehicle can upset the handling characteristics. I only mention that because you have mentioned an interest in tracking the car.

edit ** one last thing I remembered - test the rims on the car if you are going with +40 (eg clear the calipers?)

no they sit pretty flush and i have 225s....so 235s with +40 are going to stick out another 15mm...not good.

ok guys - thanks a lot for the advice, i really appreciate the help :thumbsup:

albii, yfin - i'll take your advice and go for something with a more suitable offset :)

Chris_F

just found out the rims are actually +42 offset. I'll test one of the rims on the car beore i buy to make sure they don't stick out past the fender

albii

even still 235 may be a little too wide...225s may be the go though..

hmm ok.. ill be running 225 for a while anyway.. maybe wait till i get a front camber kit before i run 235 :p

If its to wide invest in some spacers for the mean time.

Chris_F

26-03-2006, 01:53 PM

dont spacers make the wheel stick out even more?

I've never really figured out what they do?

If its to wide invest in some spacers for the mean time.

I don't think that is investment. It is a $35k car and he will be jeapordising his insurance as it will not be legal - at least that is the case in Victoria (and you will probably find other states too).

26-03-2006, 02:39 PM

yea i wont be using spacers

Just a quick question about the 17"x8.0.

1. Will the stock tyres be OK on the 8.0 inch width wheel?

2. What issues would there be if any?

3. Any real advantage to the 8.0 inch versus 7.0 inch?

Thanks a million.

Chris_F

28-03-2006, 05:44 PM

zuiko, what size is the 17" tyre that comes standard with the euros? i think its 215 which is the lower limit of an 8" wide tyre i think. I'm sure you should be able to run it, but on an 8" wide it'd probably be better to run 225 or 235

basically 8" lets you run wider tyres where as the limit for the 7" is 225 (ideal tyre width for a 7" is probably 215 tho)

Chris,

The 2006 Luxury has Bridgestone Potenza 225/45 R17s which are quite nice tyres actually.

Sounds like I can go for the 8" for a bit more width - the high offset on our car means that you don't get that nice curvature in spokes you see in some pics and which I happen to like. So a wider wheel should allow a bit more of that spoke curvature.

When I replace the wheels at least I'll have the option of 235s.

They obviously don't rub against the car being only 1/2 an inch wider on the inside.

Here's what I mean by the offset affecting the curvature of the same model of rims. On a high offset car the mounting point of the rim has to be further out towards the lip and therefore the spokes running out to the rim are flatter...

whereas on a low offset car the tyres can stick out from the centre mount more and this creates a much more muscular appearance that I really like. Look at how much the spokes curve outwards here...

damn they are good tyres! yea 8" should be fine. I think for that width i'd recomend an offset comfortably above 45mm I'm tempting fate with a wheel that is actually +42 offset and 8" wide (this is probably near the absoloute limit).

i think its good to go for 8" for the extra contact patch.. but don't forget 7.5" wide rims can also run 235's except like a 225 on a 7" rim the sidewall will be softer and the tyre will be slightly oversized. I find that the sidewalls on my tyres are quite soft because im running 225's on a 7" wide rim. So the stock 225s on an 8" should work quite well :thumbsup:

hmm yea that is a nice look... but trying to get that look by going a low offset is a recipe for disaster.. keep searching man, wheels are very important for the looks of a car dont compromise on something you think looks "ok". Feel free to give me a shout if you have trouble deciding :thumbsup:

Thanks as always Chris.

The Emotion just doesn't have that curved look I really like, but I've found something that has that look (at a price of course)...

http://www.work-wheels.co.jp/wheels/index/xs2/view3.jpg

http://www.work-wheels.co.jp/wheels/index/xs2/view1.jpg

and these are both probably 17" by 8's which seems perfect.

those wheels are nice :thumbsup: i prefer the work meister c2r (i THINK that's what they are called), see if i can find a picture for ya.

Also those pictures seem to be 18" wheels.

When I replace the wheels at least I'll have the option of 235s.

They obviously don't rub against the car being only 1/2 an inch wider on the inside.

235/45/17 on an 8 inch is going to stick out at the front even if you run a +48. I am running 7.5" and at the front it is very close in that profile. The "softer" fit is actually a good thing IMO as you have extra protection for your rims. When I was running 225/45/17 on 7.5 I found it was very easy to scrape the rims - now it is very difficult.

So to sum up Zuiko - I don't see the point in 8 inch wide rims if on a 7.5" you can run 235s. You are just adding unsrprung weight for no reason and the fit is excellent for that size.

yfin, i think one of the key benifits of running 235 with a 17x8" rim is the firmer side wall, and the better contact patch this can give. The ballooning effect of having a slightly oversized tyre to protect the rim is good for practicality but it's probably not ideal for handeling.

I understand your logic of only going to a 7.5" width though and i'm starting to think this would be a better option simply because it's more practical and will still allow a 235 tyre, even if it isn't ideal.

yfin

29-03-2006, 10:21 AM

Chris - 235 on 7.5 is not oversized. It is perfectly within specifications for a 7.5" rim.

The tyre just baloons on the rim a bit more and I seriously doubt this has any impact on handling. I think flex on the sidewall has more to do with the type of tyre. I haven't noticed any detrimental difference in handling with 235 - if anything my Falken 225s had softer sidewalls.

hehe ok, it's just that i've been told in the past that a 17x8" wide rim is ideal for running that particular tyre width i wanted.. so thats what i've always believed.

hmm i think i'll go 7.5" wide then if/when i upgrade.

i'll ask the person who originally told me 8" wide is better for 235 and try and understand both logics :)

yeah find out why because i was told 7.5" was perfect in that size.

Even this michelin web site says 7.5" is "optimum" rim width for 235/45/17 so you have nothing to worry about going with 7.5. You will save weight too which I think will benefit your track plans.

thanks for all the help with this yfin

i've decided to hold off on upgrading my rims and running with what i got for the time being (i.e. getting tyres like the advan ad07 that are good for street and track in 225's)

In relation to fitment, when i do eventually upgrade my rims ill be going for 17x7.5" rims like you suggested - hehe if your ever letting go of yours let me know ;)

The reason why i was told 8" wide rims is prefered for track use etc. (it is apparently used by racing teams in japan) is because the wideness of the rim effectively flattens out the side wall, noteably increasing sidewall stifeness. I guess you could also run 245's?

ps. i wanna see some pictures of your car with the euroR kit fitted *drooling*

Juz wanne share some extra information abt tyres on euro, I have seen some CL7 running F235/45/17 and R215/45/17 semis for track use, and the PHASE CL7 running 245/40R18 semis for both F&R on the Best motoring VTEC CLUB, But i don't know wat's size of rim they are running
