Just wondering which alloy size,profile, offset would suite a vr4 saloon. tyres need changing soon so was thinking of doing alloys at same time. I want to avoid tyres rubbing and also is there much difference in ride stability. All help would be greatful, thanks.

Do you plan to do a brake upgrade of any sort ?

Do you plan to lower it ?

These need to be considered when selecting size/offset etc

neither in the near future just after bigger and different alloys

Considered for brakes Yes .. But lowering won't make any difference as long as you keep the diameter and widthe the same :happy:

Not always, I cannot fit 18's on mine without getting the arches rolled

Sorry Pete.. But i can't see why that is ??


If the Off Set is the same and the Diameter is the same and the width is the same then all the dimensions are identical to if it it where a 15" 16" or 17" wheel ?? :inquisiti

Can you get 18" wheels with a 7" width though ?

Mine are 17" x 7" with a 38 offset to get over the Kads. When I tried Kev's 18" x 8" wheels (still 38 offset) I couldn't even get a fingernail between the tyre and wheelarch

Back to the original question though, I would still stick with 17s as the tyres are a lot cheaper, but then I do use 2/3 sets a year so if you arn't tracking I guess that may also not be an issue

My Konigs are 7" rims... Thats why i have no issues with Scrubbing, even though mine is Slightly /help Lowered :scholar:

But yes, back to the thread :speechles As Pete says 17's are cheaper :happy:

18x7" wheels do exist, and if you pick low profile tyres you can end up with the same or less overall diameter. For example

205/55/16 = 631.69mm diameter
215/45/17 = 625.09mm diameter
215/40/18 = 629.15mm diameter

In saying that I wouldn't pick 18" wheels myself, they are a lot heavier and slow the car down, they are more expensive and 18" tyres are more expensive too.

If you don't plan on lowering it then 17x8" with about a 38mm offset will be fine, you will rub if you have a heavy load and a lot of people in the car, but 99% of the time you will be fine. You will also get wider tyres on an 8" wide wheel, 235/45, 235/45, 225/45 are all suitable for a 17x8" wheel.

not looking for cheapness more about style. if i can get 18's on without issues i think i will go for them. But if 17's are more suited to the car then that is also an option. I have done a few search's about wheel size an are more confused then first started. I suppose i am looking to avoid having to send a set back due to wrong fitment.

I'm running 225 40 18's on a 7" rim, and as i have said, no issues with rubbing :happy:

Fitment wise you need:

5 x 114.3
PCD 67.1mm

I run 235 40 18,s and lowered but suspension is hard. I get rubbing on dips in the road and weight seems to make no difference.
Camber is set a 2Deg so this is helping me if they where straighter i would have a few more issues.
As for weight it depends on wheel make mine are 6kg each I believe :thinking:
But you will find a pikey 17" wheel will weigh more than a pukka 18".

What width are your wheels Stuart ?

when mesured they seem to be 8.5" the tyre do are wider this tim as the previous 215 where a bit to narrower even with rim protectors curb scuffage

Wodjno
29-12-2006, 09:16 PM
I would say there 8" then :speechles As the measurement IIRC is from the Outer Front Rim to the Inner Rear Rim :happy:

Being 8" would account for the rubbing and especially with 235's on /help

I tried 235's on my rims and they scrubbed /Grrr

i will probably go for 17's, 18's sound like to much hassel, and play it safe.

SGHOM, do you run a 35 or 40 profile?


i run
18" x 8.5" ANZ Drift RS wheels 35 offset
225/40/18 dunlop DZ101 tyres,

my car is lowered,
i have also fixed the camber on my car,
-1.0 one degree on the front, and -0.6 on the rears,
i have rolled my rear guards so i dont have any rubbing.


18 x 8.5 is the biggest you will be able to fit without going for a more narrow wheel, (19 x 7s)


18 x 7.5, should fit no hassels, and you can get a 225 wide tyre on them with no probs,
and with the 7.5 you shouldnt have any rubbing issues.


i did alot of investigating when i went wheel shoping 5ish months ago!

Hi Paul

Ive had experience with 16",17" & 18 inch wheels within a year so i can give you a brief account on my thoughts;

16 inch standard wheels and pirelli p600 tires
Verdict:Avoid at all cost and change set up ASAP/pan

17 inch enkies off evo VII and toyo t1s tires
Verdict:The tires are 235/45 and they grip like a leach.You only need to do this upgrade if you buy brembo brakes (Front) /toycar

18 inch fox rs10 and goodyear eagle f1
Verdict:In my humble opinion for looks and grip this set up was my favorite and i only had to change the wheels because i had brembo brakes fitted to my car. My suspension is standard and i had no issues with rubbing whatsoever. I even had 8 people in my car and drove from leicester square to kings cross over humps and i dont remember the car scrubbing once.The size of the rim is 18x8 and the tires are 225/40/18 /rally

Hope this helps with your final decision

I have 235/45/17 Yoko Advan A046's for my evo 8 rims(17x8, +38) and they rub on the suspension at the back for some reason.. :(

But when i had my 18x8's(+35) with 225/35/18's on it i had no rub at all even with the car really loaded down..

Stock Diameter is 631.69mm, 235/45/17 is 643.12mm, 225/35/18 is 614.48mm

Thats why you didn't have any rubbing at all :)

I'm quite suprised that the owner fit 8.5 on the front and 9.5 on the rears with 20" wheels. It looks nice though, altough it's not an VR4.

Btw, mine is 18x7.5 inch 42 offset, with 225/40 tires. They fit nicely and no rubbing or whatsoever, altough I rolled my fender but I think there is no issue if the fender aren't rolled since there is quite a lot of gap between the arches and tires. I'm thinking going to 18x8 with offset 38

i want to go for a set of 17`s and perhaps 40mm lower on it, cant go to low as of where i live, but need to fill the arches up, looks so wrong....i would put it on the floor like my fastback, but my fastback was very simple and everything was metal on it, and wouldnt break as easy as the galant.....i know my galant wouldnt like to be wedged with floor pan firmly ground into the floor in a car park,

17's will fill the arches :happy: If you drop it 40mm :pimp2: Aslong as you stick to the correct diameter :scholar:

If you have a look at my car, it had 17" EVO 7 wheels and now has 17x9.5" TC-005 wheels on it. They fill the guards perfectly fine. The car is lowered by about 40mm.

My Legnum Super VR4 on 18" x 8" rims with 215/35/18 tyres. Fits perfectly with a 38 offset -even with the adjustable suspension wound right down.

Didn't even have to roll my guards.
