Beware Alloy Wheel sizes for Sirion and YRV.

Forum: 

My wife got me some New Alloys for my 2003 Sirion Mk 1.

I checked on all the sites and they all said they would fit.

Well there is a problem.

The Sirion and YRV - WILL NOT TAKE 195 TYRES ON THE REAR WHEELS!!

If you try 195 Tyres they will not turn as they touch the suspension arm at the front.
The front wheels fit ok.

So you have actually three choices.
Fit smaller Tyres 190 or less.
Fit spaces to the rear Wheels (About 5mm should do it)
Or Grind some of the suspension arm edge down so the Tyre doesnt rub anymore! (About 5 mm for a couple of inches)
I had an engineer friend of mine look at the suspension and he said they would take the
grinding down no problem as it is a over engineered piece of kit.
Drastic I know. Anyone else had this problem?

Anyway the choice is yours.

Regards, BobF.

Have this problem on the YRV but.......

Hear what you are saying. I bought Et35 wheels @ 15" for my YRV Turbo and yes same problem as you, The rear tyres flush to the rear axle, ended up getting 5MM Hub centric spacers which sorted the problem but caused another, the rear tyres catch the rear arches when going over bumps. So much that I have had to today repair paint damage and remove rust caused by it Cray 2

But a member on here has also swapped his alloys on his YRV with 195 tyres with 17" alloys and no rubbing on the rears. The only conclusion is that the ET35 alloys I have are either not et35 (Even though stamped inside of the alloy) or the tyres I have use bigger alloy defenders on the sides (Uniroyal 505 wet tyres). It is definately something to watch out for. Saying that a on-line wheel store on the internet only advises using 185 tyres on the YRV, must be something in it.

Don't like the new shape much.

I believe with 17 inch rears you would actually get passed the Suspension problem, as it would still be the alloy wheel where the suspension touches the Tyre.
And the tyre wouldnt have actually started Cray 2

It is the bulge in the new Tyre that caused my problem.
Get a Tyre with no bulge - No Problem !!

Criky you friends Tyres must be really thin Must be like driving with no suspension at all Biggrin

My solution was to grind down the suspension. Then you don't get the rubbing problem because you had to fit Spacers. Worked fine.
And then painted the bare metal black with a rust inhibitor paint.

But watch out for the Brakes Pipes Blush

He used 3mm Spacers

I think he did the same, ground down some of the suspension and used 3mm spacers to get passed the brake pipes, which gave him enough to stop the rubbing against the arches.

Of course the real easy solution is only to fit tyres of no more than 185. Then there should be no problem. (I Hope) Smile

Siron Tyres

Hi Bob, Yes 185's are fine as they fit these to the Sirion Rally. The 15" on my Rally2 look great but I suppose 16s or 17s would fill the wheel arches better. Any Pics, of your mod?

Strange going on.

The League Midas Wheels I am using have the same offset as you mention.
It would appear to be the Tyres that are causing the problem.

The company my wife bought the wheels from. Have now offered to supply and fit 185 Tyres as a replacement for the 195's, as they say they will fit my 15 inch Midas Alloys no problem.
Even though I have done the modification. I may take them up on it , and there will be a couple of weeks delay !!
But Hey the weathers not too great at the moment, so not in much of a rush.

Wheel sizes

Hi Bob,
i have the 17's that jpor mentioned on my YRV Turbo.
The tyres are 195x40x17 Toyo's and not that bad a ride at all. The previous 195x50x15's seemed worse to be honest. Handling has improved too.
To get them to fit right its all down to the offset.
The original 5j rim has a 40mm offset but a 7j needs 35mm.
You and jpor are both right in saying some tyre brands bulge more than others even with or without rim protector bar.
I think 195's should fit the Sirion too with no problems if you get the offset right, a couple of mm's makes alot of difference.
The tyre was close so i did a slight grind on the end of the rear suspension beam, sounds drastic but only took off some of the overhang and it actualy cleaned up the welding.
I measured a 15" 195x50 Toyo TS1 and a 15" Yoko A509 195x50 today, that i have in the shed. The Toyo was 195 wide but strangely enough the Yoko was visably narrower when put end to end and was only 185 wide???
Just put a 205x40x17 on a rim and that fits, strangely as it sounds its about the same max width as the 195 version except this time the walls go straight up and do not lean inward.
I noticed the Sirion upgrade alloys have a front fitting kit listed in the description. Its just a 3mm spacer to avoid catching were you have discovered.
You can get 3mm spacers if you know where to look and they are hubcentric (same centre bore 54.1mm) too.
Cheers,
Dave.

I think I will stick to the Steels Biggrin

Criky there are so many ways to do this mod the mind boggles !!

The 195s fit the front no problem, its the rears catching on the suspension beam as you say. I have ground some off to make them fit. Always worries me when the tyre is so close, and I get worried about spacers putting more pressure on the studs.

The 185's for me I think.

Talk about confused. Anyway anytime now they are going on one way or another. (And all because my wife bought me them for Christmas)

Not complaining though - It will get done. Wink

Just had a look on

Just had a look on mytyres.co.uk and they have a good sizing chart for cars. Maybe worth having a chat with them to see if you can get a narrower 195 tyre, that way you'll get the max tyre width that maybe better thanthe 185's you are looking to resort to.

I have just had the Sirion in the Air on Stands.(Beautiful Afternoon here)
Tried all four Alloys with the Original Tyres and after my Grinding of the Suspension beam on both sides at the rear I have a 3mm gap. So I think I am there. Smile

Checked Rear Shoes, still a good 3mm on them so back on with drums after rub down and painting Gold with Hammerite Smooth.They are going to look wicked, anyone would think I'm 24 - Not 54 Biggrin
Still waiting for spigot rings !!! Aaarggghhh.
But i'm getting closer- slowly. Cray 2

I will have a look at the tyre site, thanks for that. Wink

had same problem bob,had to

had same problem bob,had to use 5mm spacers on rear,but fine after that,could have got away with 3mm Smile

I'm having trouble too.

I got a set of Toyota Corolla TSport Alloys 195/55/16 and they will not go on at all. The rears even with 5mm spacers are a no. The fronts will not fit due to the profile of the tyre.
Have I just wasted £200? - they have good rubber too Sad

I am thinking of getting a low profile tyre fitted and seeing if that helps as it's only catching on the bulge.

The offset is bad at ET45 on a 6J rim, have I any hope of them fitting?

I am using MINI steel wheels

I am using MINI steel wheels on mine, 15" 5.5J ET45. 195/50/15 tyres.

The rears needed a 5mm spacer shim, and a little 1-2mm dremel grind off the suspension arm seam edge (no structural issue)

Front went on fine but were sitting a little too far into the arch, so I fitted 3mm spacer shims on the fronts, didn't want to go any thicker as there isn't a great amount of wheel stud thread engagement otherwise.

195/55/16 is going to be way too tall anyway affecting the rolling radius so worse acceleration/braking, and the sidewall buldge is part of your problem.

I think you will be best off trying 185/50/16 or 195/45/16, But likely you will still need a slight amount shaving off that suspension arm seam edge.

185/50/16 on a 6J will sit

185/50/16 on a 6J will sit much better on the rim with much less bulge than 195/55/16.

Sirion Rally 4 and 4 Trac.

The above will take 195s no problem as the rear suspension is completely different on these two models from the front wheel drive only models.
In fact my brand new Vredstein Sportrac 3s are on my Original 7 spoke alloys, ready for fitting in a couple of weeks as I get ready for the Japfest at Castle Coombe. Smile

Will 185/50/16 fit on the front

Will 185/50/16's fit on the front as the 195/55/16 wont as its too tall and hits the suspension. The wheels on the rear will turn but scrubs so the 1-2mm should be enough off the arm once I get the right tyres on.
Thinking about going for 195/45/16's due to the lower overall diameter than the 185/50/16's and even the standard 185/55/15's as I am worried about the front suspension. A site I found gave some useful info, just hope the 195's fit the rear OK.

http://www.kouki.co.uk/utilities/visual-tyre-size-calculator

Cheers for all the info, much appreciated.

Same thought

The 195/45/16's are a smaller rolling radius than the 185/55/15's but wider which I would like. Only trouble is the 185/50/16's will fit better on the rear but I could do with measuring the gap on the front suspension to see if they are too tall to fit. Still don't know what to do, i would like to try getting them to fit without grinding the suspension arm.

Pictures of finished job!

Don't like the new shape much.

I haven't actually fitted then yet as I am still messing about getting all the stuff together (New Discs and pads etc)
As I am doing 72,000 miles service at same time.
I just tried the wheels to see what they were like and found the problem. Blush
I'm still dealing with it and playing around etc. And waiting for some decent weather do do the job properly.
No fun doing this sort of stuff in the wet and cold. Sad

Hope fully not long now. I will put some pictures on then ok.

Looking good Surprising

Looking good Wink Surprising how the sirion and the YRV looks to be the same down at the chasis level. Alloys look very nice. Smile

Consider not only the wheel

Consider not only the wheel offset, but wheel width. With inside clearance being the issue to solve, As you go wider, the offset needs to be lower (more wheel width on the outside than inside)

I imagine the OEM 5"J steels will be in the offset region of ET42-45, So with a 5.5J or 6J wheel you would need to go to a ET38-40 offset.

Trouble is, most aftermarket alloys in 15" or bigger are a 6.5J / 7J.

And yes, tyre width and profile also plays a part with the amount of sidewall buldge. Even the same size in differnet brands can vary quite a bit..some tyres have thicker rubber on the walls and kerb protectors to help protect alloys.

3mm or 5mm spacer shims are cheap and easy to help push the wheel out, but be warned DO NOT use a wider spacer than 5mm as there is unlikley to be enough length remaining on the wheel studs. Longer studs could be pressed-in if needed.
