16" imola wheels all round?
Discussion
Dammit! , ended up buying a pair from ebay. Hopefully they will go on with spacers because i would really like to keep the more standard look. I cannot believe how many wheels are available for the 4x108 fitment but dont look right on a chim?? The SP12s are about the nicest i have seen but at a price. Hopefully mine will look as good as Richard 858s car a few posts up^^^^

Thanks QBee, but if i can make the imolas work then i will be happy. Until i can find and afford a set of either SP12s, racelines or even better OZ pegasus like in this thread (retrowheels pic )

TVR designed the Chimaera with 15" wheels on the front & 16s on the rear to achieve the correct rake, so if you choose to go 16s all round you really need to ensure the correct rake is dialed back in.
Easy if you've got adjustable coil overs, or you could select tyre profiles to help, I have 16s all round and did a bit of both.
Here's my car with some nose down rake dialed in on my Gaz Gold Pros with the rest courtesy of my tyre choice.
I wanted the correct rake and a practical ride height, but I also wanted to fill the arches for the right look, the taller 55 profile rears help here.
The 55's also put a bit more air at the rear which noticeably improves the ride quality over our wonderfully paved roads in the UK
I'm not big fan of low profile tyres on the road, all you end up with is a terrible ride and tram lining.
The Chimaera was designed as a modern interpenetration of the classic 60's sports car, stick rubber band tyres on and it looks totally wrong to me.
In 1887 John Boyd Dunlop came up with the genius idea of the pneumatic tyre, by filling a rubber bladder with air he revolutionised personal transport at a stroke.
These days it seems everyone thinks its a good idea to delete almost all the air by fitting low profile tyres, you might get away with it on a modern car with extremely sophisticated suspension designed for these rubber band tyres from the outset.
But on a Chimaera.... you definitely benefit from the genius of Mr Dunlop

I am currently on standard coilovers but adjustables are on the cards. My new 16s should be here early next week so i will experiment with tyre sizes. Did you have any problems fitting 205s to the 16s? Seems a bit narrow for a 7.5 wide rim?
I currently have 225/50/16s on the rear and was considering either a 225/40/16 or 215/45/16 but chimpongas's looks good with 205s on (which are the same size as my old 15" fronts?)
Hmm??

I know what you mean, there is something very nice about big fat balloon tyres on old race cars . Although i wont be going quite this far they are still cool. Like these-http://www.redbubble.com/people/roibrooks/works/64...

I have a thing about steering feel, steering feel is one of the tactile pleasures of driving, put unesserily wide tyres on the front and all you'll do is dull the steering feel.
This is why I went 205 on the front which fit perfectly on the 16" rims
There's really absolutely no need to have wider front tyres on a Chim than 205's unless you're into track days.
Call me old school but I also like to see some tyre wall on a classic...
Look how right this original Cobra looks on it's correct rims & boots
Now look how awful this replica Cobra looks on nasty aftermarket aloys and low profile tyres

The TVR standard set up of 205/55 15 and 225/50 16 gives a rolling diameter difference of 25 mm.
Chimpongas's set up gives a rolling diameter difference of around 63 mm.
I am not saying he is wrong......but I have always thought it was 25 mm for a reason.
Two of us have run the cars on track days with the same size wheels and tyres all round, and that has handled fine.
I am now careful to keep my set up as close to 25 mm different as possible - perhaps I am wrong?
To be fair to Chimpongas, he is more interested in comfort, I am more interested in flat high speed cornering.

You beauty, that's the idea, the Lotus, see the negetive camber on the rears, looks toed out also?
Looks broken, years ago another chap I knew had a Ford mustang with small front tyres and huge, massive rear ones, now that that some rake. I had an Opel Manta once and that came with American Firestones, rock hard stone cold tyre but I painted the Firestone White and loved em, hahahah, deadly in the wet.
I think Chimps on to something yet again!
Maybe a 14 in rim with bulging tyres over them.
I also like the look of all that smooth rubber on the side walls of these retro tyres all the classics are racing on.
The other week I watched a guy driving a 60's MBG Roadster flat out into Paddock hill( turn 1) Brandshatch and just leaning all over the rear tyres, sliding and scrubbing speed off in a deliberate action, he blew the others away, those tyres can take some stick.
I'm realising the only way I'm going to get 17's to feel good on the road is to get the softest tyres I can.

So is the 225/50/16 the genuine size for the chim?
Had a look on a tyre comparison chart and the tyres are as follows
225/50/16 631.4mm
205/55/15 606.5mm
225/45/16 608.9mm
So the size that Richard uses on his car (earlier in this thread) aren't too far from standard 15" combo diameter but with the extra width. So i think i will start there

When fully gassed up and with a 5 gallon fill of petrol I've got 30kg of additional weight in my boot Anthony, I've found this additional weight aids traction & improves handling, as we all know these cars are very light at the rear.Chimpongas's set up gives a rolling diameter difference of around 63 mm.

But in truth its all about balance, and in my case perfect balance is achieved adding by a small amount of additional forward biased rake.
A bit more tyre at the rear does help improve the ride quality too, so you can have optimised handling and a more refined ride at the same time.
Corner weighting helps take the guess work out of it

I did think about sticking a paving slab in the boot........but decided it might just make me spin on track faster, rather than the (desired) less! And I am not about to test it out on the narrow twisty confines of Cadwell Paek today.
I agree with your comments about over-trying 100%. I always have 215 fronts, and my track rears are 225 or 235. I would rather my tyres had some bite in such a light car.

Just to clarify I have 16" Imolas all round with Toyo Proxes T1R 245/45/16 rear and currently 225/40/16 front. The fronts do not foul anywhere even without spacers but the previous fitment of 225/45/16 do look a bit better within the arch profile (IMHO & Daz's)) however ride height does need adjusting & 5 - 7mm spacers fitting to clear inner arches & wishbones properly.Paul
I do like the look of some of the spider type wheels but as everyone knows, I'm a stickler for keeping everything original !!!!!
Time for an update. Current set up is what came on the 2nd hand wheels-
Fronts 225/45/16 bridgstones on standard rear imola with 5mm spacer to clear brakes
Rear 225/50/16 Avons on standard rear imola with no spacers
Although the ride is quite good, on anything other than perfectly smooth surfaces the car tramlines really bad. So much so that if you hit a bump at more than 40mph it can tear the wheel out of your hand
With the old 15" wheels (205s) i didn't get any tramlining or bump steer so am considering going to either 205/45/16s or 205/50/16s to try and settle it down a bit
Any advice?
Thanks guys

Are you sure the 323 discs fit behind a 16" rim ? I have gone for 300mm just to be on the safe side .
I have 323 brembo conversion and they just fit behind my 16 inch estorils with 12mm spacers. They do not however fit behind my 16 inch TD wheels which will now have to go. If your thinking 16" Imola's I would try fitting them on someones car who has the upgrade fitted unless someone has already done it. I am Burton on Trent if that helps anyone.Gassing Station | Chimaera | Top of Page | What's New | My Stuff
