Unless you've just spent a small fortune on a complete chassis refurb, in which case that philosphy no longer works. (for me) biggrin

Yep, but you're miles away and posting them would be a right bugger for me. If you still haven't got a pair by the next time that you travel through Essex (J30 of the M25) send me a message smile

I've got a pair of 16in too if anyone close is looking.

I've got two sets of Estorils... the 16's are on the car front and rear, so I've got four 15's.. two at home and two at V8D's in Lincolnshire...

I've been toying with some Image wheels, so could potentially have two sets of 16/15 Estorils for sale... Dunno what the going rate for Estorils is though... I'm thinking maybe £1k per set wink

I have picked up a pair of cheap 205/50/16 tyres to try on my wheels. If that cures the tramlining then i will be a happy bunny. Hopefully

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.
  • Fronts 205/45/R16
  • Rears 225/55/R16


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 rolleyes

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 yes
Hi Dave
Is there any difference with speedo reading with 16 all round ?

Are the rain sport similar to Toyo with softer tyre wall?

Fitting 16" wheels on the front is obviously not going to have any effect on the speedo reading, the speedo pickup is on the diff and the car came with 16" wheels on the rear so only the rear tyre wall size (rolling radius) will affect the speedo reading.

I run a taller than standard rears at 225/55/R16 because I like the ride they give, but it does mean my speedo under reads by 7%, when I'm driving at a true sat nav conformed 30mph the speedo shows 28mph, at a true 60mph the speedo shows 56mph and 75mph when the car is genuinely moving at 80mph.

The small amount of speedo inaccuracy really doesn't bother me, as I say the benefit of taller than standard 225/55/R16 rear tyres is better ride quality.

Assuming you don't buy the XL version the Uniroyal Rainsport 2s are a soft side wall tyre like the Toyo and I've been very happy with their ride, wet and dry weather grip, but they've been discontinued now and replaced with the Rainsport 3s that seem to be getting rave reviews of late.

Thanks for that Dave, slightly under ok it's when it's the other way is issue for me

Just watch the manufacture date of the Rainsport 2s on sale, I believe Uniroyal stopped making the 2s some time ago so the ones you're considering may have been sat on the shelf a long time?

It's certainly worth quizzing the suppler on this point before you buy.

Dave, do you have an opinion on grip, 2s vs 3s?.
I have never had 2s, and my 3s are awesome, but on my Saab, not my TVR.

I like the size of those rears Dave. I've just checked and if I'd gone for a 245/45/17 I'd get a very similar outside circ. smile which would make it easier to get my rake and suit my already large fronts more.
Also very interested on your thoughts re 2's v 3's although I'm sure there both similarly good smile

I can't comment on the Rainsport 3s chaps as I've never run them, I've only ever run Rainsport 2s and they've been great. One thing I can tell you is 'V' pattern treads are still by far the best at shifting water.... but they're noisy, this is the only reason manufacturers have gone over to asymmetrics, the Rainsport 2 is a 'V' pattern and the 3 is asymmetric.

The thing is tyre noise is the last of your concerns in a TVR, everything else is so loud you simply wouldn't hear the difference. This is why I favour my 2s, after seeing my mate put his Tuscan into a central reservation in torrential rain and standing water I promised myself good tyres with the best water shifting qualities would be my priority.

TVRs are light cars with wide tyres so if your boots aren't shifting water properly you'll be aquaplaning in standing water conditions for sure,the Rainsport 2s offer great dry weather grip and they're absolutely brilliant in the wet, what I wasn't expecting was how long they last which will be 25k in the spring of 2018 when 'Ol Gasbag' will be needing some new boots. If you take a look at the tread on a new Rainsport 2 it's so deep you could lose your Grandmother down there, so its no wonder they last for ever.

I'm not sure the 3's will last nearly as long which is good for Uniroyal's sales figures but not so good for our pockets, sadly the Rainsport 2s aren't made any more, having been replaced 'unsurprisingly' with the quieter asymmetric 3s, by all accounts the 3s are a great tyre though so that's what I'll probably go with, they are excellent value if purchased from Camskil too.

Finally I'm a great believer in a taller sidewall, it looks right on this car to my eyes and definitely gives a better ride which sounds like I drive like an pensioner but actually couldn't be further from the truth. I've found in these cars a more compliant ride makes you way faster on the the road, this is because your actually soaking up the bumps not skipping over them and crashing into the hundreds of pot holes we all must suffer every day.

If you fit Ben Lang's improved big rubber bushed Mk2 Tuscan 'S' Bilsteins and run 205/45/R16 on the front and 225/55/R16 on the rear (as I do), you'll soon see what I mean, to be honest it's simply a massively nicer car to drive than when I ran lower profile tyres and rose jointed Gaz Gold Pro suspension.If you mostly drive on the road forget the cheaper fully adjustable rose jointed track day focused suspension and low profile rubber band tyres you see so often fitted to Chimaeras, go Bilsteins and bigger side wall tyres that actually hold some air and you'll be in the faster street car for sure!
