Shouldn't be a problem as in I wouldn't even need a roll? I don't want to mount them then find out I will and screw up new tires. Also don't wanna chew up winter tires waiting to do a roll lol.

No rubbing.

Edit - had some time to respond better now lol

+45 pushes you closer to the fender by 7mm. 7.5" rim adds around 6.3mm per side. On the fender side you would be around 13.3mm closer to the fender than stock. On the strut side you would still be almost 1mm further out (towards fender) than stock.

225 tires adds 5mm per side (compared to stock 215) - so on fender side you'll be about 19.6mm closer than stock - a hair over 3/4 of an inch. On the strut side, you would be about 5.7mm closer to strut than stock... Less than 1/4 of an inch.

You will have no problems on the inside side and on the fender side, I'm 90% sure you'll be ok. With my 18x8 +48 I was out a total of around 21.7 mm and I did need to roll the rear slightly. I was also dropped around 1 inch. If you aren't dropped as much as I was, you'll be even better off.

The links in the OP to the calculators will give you a visual idea of what the new size will do

[exentix]

Thanks that's exactly what I was looking for. New to upgrading wheel size so I'm not totally comfortable with how it works lol. I actually have NO drop so yea haha. I guess I'll throw em on and load it up just to be sure but I at least have access to a roller if need be.

just wanted to confirm that they do fit. looks great. pics in the wheels and tire section under white ms3

Welcome! I learned a lot about wheel fitment while searching for wheels lol

I see it says 17" is the smallest that will clear the brakes. I'm looking on tire rack and CL for a cheap set of winter rims/tires and I'm even willing to go with steelies but tire rack doesn't sell steelies in 17 and they recommend a 16" setup for winter tires. Why would they offer this if a 16" wheel won't clear the brakes? Just wanted to confirm that the 17 is the smallest.

I might just find a set of wheels I like and put them on the genpu and use the stockers for winter/auto-x. My head is spinning with all this wheel talk though. Going to have to sleep on it and come back and re-read all of this.

16" fits. its been answered time and time again. just search some winter setups on here to see. i run 16" winter wheels.

With half a tank, I still get some very minor rubbing at highway speeds hitting dips... I'll probably be raising the car 1/4" soon though, so hopefully that will take care of it... If not, I'll go to 225/40s once the current tires are thrashed...

[jeopardy98]

Well that might be good info to put in the first post since this is the "everything you need to know about wheels" thread. Thanks for the help!

i'd check tires-easy.com too. i just got a set for Hankook v12s for $150/tire. by far the best rate i found. they shipped to a local installer who put them on for me.

I've always found discount tire direct to be cheapest with free shipping! And they price match also.

good to know. i checked them out but the Hankook's were $186 each and i didn't know they matched prices.

sounds like the best idea is to find the tire you want, look it up on each website, find the cheapest price and then order from there or have another company price match.

Nice choice, that looks perfect, maybe I will get some spacers for my rx8's.

when i had rx8s i ran a 3mm up front and a 5mm in the rear and i thought it looked perfect. here are two pics for your reference.

were you running 235 width? and with those size spacers is it necessary to get hubcentric adapters? seems like the hub might extend more than 5mm, but i really dont know.

and is that an elise?

[dastpe]

Yes, running 235/40 with the most minor roll because I would rub with a full car of people. Does not need to be hubcentric, mine were $4 a piece. No, its an exige.

Alright guys I need a little bit of help. I'm going to need new tires soon, and since most of my bills are paid off, I think I'm going to get rims and tires. I'd like to go with some alleggerita's, but at $400+ a rim, I'm going to go the cheap route and get some rota's. I'm on stock suspension for now although I wouldn't mind having a drop in the future (car is dd, so will probably never go coilovers, so probably just cobb springs). I'd like to go 18x8, and as far as I can tell I will need about a 45+mm offset? I'd like to be able to put at least 235/40's on them, but it would be cool to be able to stuff 245/40's on em. Any idea's on what it would take? According to Nitto's site, the difference in overall width for the 245 vs. 235 is just over a quarter of an inch, so it seems like if a 235 will fit, then a 245 should. Does anyone have this similar set up? Any input is appreciated, thanks!

you and I seem to be in the same boat. I'm not lowered yet and want to get 18x8 and my only offset options are 35 or 42mm, or 45 and I am currently on 225 but want to go to 235 later. I do not want to roll or pull that much, but will if necessary

BTW, gen1 ms3 here
Seems like 35 would be too agressive.

Yeah it seems like I could run a 245 if I don't go with a super aggressive offset. I will roll my fenders if I have to but I don't want to have to pull. I'm thinking somewhere in the 45-48mm offset is going to be key, but unfortunately we don't have too much of a difinitive answer it seems...

With 245's on rx8's you need to roll the rears (Gen 1). Not a flat roll but one none the less. I'm not lowered and after rolling, rubbed only once when hit a huge bump doing 80. Considering ur lowered a lil if u have the car full of ppl, u may occasionally rub on some bumps.

Someone else needs to comment and confirm on the fact that ur lowered.

I would recommend 45 or higher offset for 235's comfortably on an 8. Comfortably meaning ul'l be fine with just a roll

Your right, you basically want to stay above a 45 offset to run tires with some width. The higher from 45 you are, the less aggressive of a roll/pull you need. That being said, just rolling it flat or a slight pull isnt that bad if needed. As long as you stay high up in offset and dont overdo it in the wheel width, you will be fine with a good roll..

I don't have a desire to run anything larger than an 18x8. Also I would like to run a higher offset as I like the tucked look more than herra frush. Do you think +45 would be good, or should I try to go with a +48 - +50? (The two rims that I want at this point have a +48, and +50 respectively) I know its not a huge difference, but Id also probably rather roll the fenders than fuck with spacers. I figure I'll have to roll the fenders if I ever want a drop anyhow (which I wouldn't mind a prokit or cobb drop).

[ScarMS3]

I was just looking this up today to get some for my rx8 rims, seems that it will very rarely rub on stock suspension, but 235 never will. +45 would put you in the same ball park as me so I think you could do it,but down the road if you drive a bunch of fat people around you mint need to roll the rear a bit.

Thanks! If I stay with 225 could I manage +42 offset?

I just found out my friend who works at discount can get any sub 200 dollar wheels at a decent discount, and drag wheels for about 50 off.
That being said, any suggestions for some 18x8 wheels for my cwp? I was thinking the dr34 but I also like thick spoke like the rx8s

[silvapain]

Konig Milligrams 18x8.5 et45 with 245/40R18's. I need a 5mm spacer up front to clear my KW's, and it will need a minor pull in the rear (already rolled).

Rear:





Front:

[Nliiitend1]

So did you really "need" a full 5 mm up front or do you think something like a 3 mm spacer would work?

I'm wondering if one could get away with those same sized wheels running a 235/40 without the use of a spacer in the front, or if I should just stick to an 8" wide wheel to avoid having to fuck with it...

[silvapain]

I couldn't even fit my pinkie between the strut and the tire. I wanted as much clearance as possible without having to put in longer studs, which is why I went with the 5mm spacer. I'm not really sure what the 'minimum' amount of clearance is needed between the wheel and strut/coilover.


Both a 245/40 and 235/40 tire can go on an 8"-9.5" wide rim. I wouldn't use the minimum wheel width for a tire, as it will 'muffintop' and the sidewalls will flex more when cornering.

There's really no consensus, from everything I've ever read/heard. Some of it depends on the rigiditiy of your wheels, some of it depends on how sticky a tire you run, and some of it depends on your tire sidewall aspect ratio...

Did yours actually make contact without them (the spacers) or were they just "too close for your comfort?"

I'd say that I'd like to have 5mm clearance to be safe. That should allow a few mm of deflection without any "kissing" going on between the tire and the suspension under heavy cornering loads...

[travis9935]

How much are you lowered on your setup?

[silvapain]

They cleared without a spacer, but I don't know by how much. I'll have to put them back on and see if I can get a measurement.

Originally Posted by travis9935 How much are you lowered on your setup?

Rears are as high as I can get them (the KW's lower the rear TOO much IMHO). I really don't know how much lower than stock I am; it's been so long since I had the stock suspension on that I can't remember what it looked like.

I can get a measurement from the axle center to the fender and post it up.

[Jake5713]

So on genpu are 235-40-18s NT05s going to be fine on stock rims? Haven't really seen anyone on this setup
Stock suspension as well

My 17x9 +45 RPF1 with 255/40-17's are about 3mm from my front shock housing and it hasn't rubbed as far as I can tell.

OEM front struts, I presume?

[Celestspeed3]

Yes

[Nliiitend1]

Yeah you have quite a bit more room than those of us running coilovers... It's not really the strut body that we're worried about. It's the bottom spring perch, but at any rate, it's good to know that you're getting less than 3 mm of deflection under load.

[Domino81]

I don't know that I've ever seen 2 sets of wheels the same. 18x9 + 35's sit more flush than Dan's 18x8.5 +45. I just don't get it. Makes me worry about my 18x8.5 +48 a bit.

[silvapain]

I put the fronts back on. Without a spacer, I have 6-7mm clearance between the coilovers and the tire sidewall.

There's plenty of space between the lower spring perch and the tire.


Tapadatass

[Celestspeed3]

If you are worried about the spring perch, have you tried using a smaller spring and just raising the perch to maintain the travel.

Maybe that's not even possible I have never seem the clearance on coilovers.

[Nliiitend1]

Originally Posted by Celestspeed3 If you are worried about the spring perch, have you tried using a smaller spring and just raising the perch to maintain the travel. Maybe that's not even possible I have never seem the clearance on coilovers.

On our setups you could remove the helper springs and get a lot more room by raising the perches, but then you'd have to worry about the spring coming unseated every time you let the front suspension come to full droop...
