Staggered wheels setup - questions for those who have

[Atik]

I've just acquired a nice set of 17" alloys without realising they were a staggered size. Fronts are 8 inch wide and rears are 9. I'd already purchased a set of 225/45/17 tyres for them and I'm happy they will fit on the wheels without problems.
I don't have any offset numbers so I know my question here is probably useless without them. I wanted to make sure they would be ok to use on the Legnum.

Provided I have no clearance issues, I cant see why not as the tyres are all the same make and size so the rolling circumference is good.
I just wanted to make sure I wasnt missing something obvious! Cos if I cant fit them, they'll be going onto the MR2, and my existing Evo 8 alloys will get the new rubber.

I know that @Confused and @adaxo have staggered wheels so it should be fine I expect.


If I have to consider arch rolling, how much should I be looking at to get them rolled back?

Running the same size tyres will give a different circumference.

I'd run 215's on the 8's and 225 on the 9's or alter the profile in a similar manner.

Other than that spoke design and offset would be important to know, but there's a good chance they will fit :-)

Well Atik, all I can say is, that I needed arch rolling at the rears for my Evo X alloys and this ended up in getting both rear quater panels painted, because the paint had cracked. :-/

I have 8.5J18 / offset +38 and 225-40-18 tyres plus a low setup of coilovers. The wheels used to scrub every time, so there was no way for a PFL that they fit without arch rolling. The FL cars have slightly different rear quater panels, so that they fit without problems.

The issue with the PFL wheel arch is, that there are 2 panels joining, where the arch needs rolling. This section is very stiff, so you need to force it with a hammer etc first, before you can apply the rolling machine.

Thanks Darren and Stefan

I've resigned myself to fitting the Azevs to the MR2 and keeping my current E8 alloys with the fresh rubber. Too much hassle otherwise!

Just go and try them you lazie sod you could be surpirzed

[Atik]

I seriously doubt it will work, as they are my current wheels are almost level with the top of the rear arch. No way the wheel will make it with the current 245/35 tyres. I plan on test fitting tonight but I'm not expecting them to work.

[Pugme]

I run 10j rear et27 the arches have been rolled gently gently with a heat gun so no cracks and mine runs fine fronts have plenty of clearance on 9.5j et 17

You need to try harder atik.

[exevoowner]

Thought you had coilovers on your car ?@Atik

[Badger_01]

Atik, why is your name white instead the normal member blue? lol

[Atik]

I'm on very low coilovers.

But bad news people, the wheels dont fit. The centre bore on the wheel isnt big enough.

Also I need to renew to become blue. My Paypal account is currently awaiting verification or something and havent got round to sorting it.

Cough schoolboy error cough

Back to this thread again...

The same alloys, considering whether they can safely go onto the Stagea. Stock suspension almost on scaffolds!

The current tyres are 245/35 rear and 215/40 front. The rolling circumference is 74.619 inches rear and 74.682 inches front. I'd say that's negligible?


Do I run the risk of damaging my diff by running staggered? If there is an inch of rolling circumference difference, what happens after 10 revolutions, does that increase to 10 inches and crunch the diff? Google results suggest that a difference of 3-5% is tolerable.

[Confused]

I've done 80,000 miles in my Legnum since having it, and have been running it on different sized tyres all the time.

Fronts are 235/45/17, rears are 255/40/17.

Nothing has gone bang yet! Obviously can't guarantee whether it'll be the same for the Stagea!

[Nick Mann]

If my calculations are correct there is less than 0.1% difference in rolling circumference. It would be similar to running identical tyres all round but one axle having 2mm more wear on the tread.

[billybobboot]

I use a website if you type tyre comparison into google its one of the top answers this alows you to check all tyres sizes.
It alows you to campare to sizes against eachother and will even tell you what sizes have the same rolling radious.
E.g can look up 215/40/18 and it will tell you all the closest sizes including % and if there are any the same size e.g. 245/35/18 is same wct ect you can even check a 17 against a 18 ect.

[Atik]

Looking into this over the weekend I've worked out the plan.

Get the Azevs over on the Stagea when the MR2 is sold, make use of the existing 245/35 and 215/40 Eagle F1 GSD3 tyres and then change to 245/40 and 225/45 when I need to change tyres. That'll give me the bigger side-wall as I'm not too keen on such low profile tyres.
The difference is 1% with the fronts bigger than the rear but that will be negligible.

The offset on the alloys are huge though! Just looking at the wheel, I can see that the new wheels will sit a further 3" out compared to the 17s I have now! Fill up the arches a lot better and give an ever so slightly wider stance.

[Nick Mann]

If the wheels stick out more, then the offset will be smaller?!

But either way, we need before and after photos please!

[adaxo]

Absolutely correct, less off set = wheels poke more out of the body, car looks 'wider' but it also sit a bit lower as by applying the same weight (of the car) further off the centre (of the car) you put more tension on the spring, hope that make sense.

[Atik]

Ahh yes, that does make sense. The new wheels will sit out a fair bit compared to the current ones or the stock wheels. Even if the car sits 5mm lower due to being wider, the scaffold height stock suspension will give me a huge arch gap anyway!

Pics will be provided as this happens

[Atik]

Tried these on the Stagea over the weekend. No good. Centre bore is too small. Would need 8-10mm spacers.
Decided to sell them off now so on Ebay they go!
