Hi,

Does anyone know the correct tyre size for a 20v Turbo Plus? Does it vary from the standard 20v turbo at all.

Also has anyone run Avon tyres on a coupe before?

Thanks

Hi there....

all the info you need is here -

useful info

225/45 ZR 16 for a plus...

iv run Avon before, good tyres, Toyos & Falken 452s are highly recommended on the forum though! laugh

Rich is spot on with that. And to answer your other question, yes they do differ from the standard 20v turbo, which run 205/50/16's

Cheers guys, my main priority is to have a good all round tyre but durability is probably top of my list. I've also heard people talk about Dunlops and Continentals would they be in the same league as Toyos and Falkens?

I ended up going for Falken 452 recently on my coupe and they have been brilliant. Had a good run out in the Yorshire Dales at the weekend and they were superb. (the roads started off really wet, then dried out towards the end of the run)

I had Kumho KU31s on previously and they were brilliant on a trip to the alps earlier on in the year. They performed really well on 2 sessions at Spa too.

And I Had Toyo Proxie T1Rs on my previous 16vt which were excellent.

So basically, my advice is go with whichever of the above you can get for the cheapest! smile

I would suggest that Continentals in particular would be a league above Toyos and Falkens, i have continental sport contact 2s on my car at the mo and they are the best i feel i have had on the car, previously i had goodyear eagle f1s and prior to that bridgestones, eagle f1's good tyre but seemed to wear quickly, bridgestones seem to last forever

Just put a couple Vredestein Ultrac 205/45 17's on, and am pleased to report that these increase the ride comfort over rubber bands and are brilliant in the wet.

Re: Tyre Sizes - 04/12/2011 17:28

So there ARE 2 sizes confused Which is best though?

stock 20vt and LE (as they came from the factory) 205/50 r16
stock 20vt "plus" 225/45 r16

some late 20vt(6) came with 225/50 r16 from the factory, but it was a bit of stock clearance in the final year of production. It's irrelevant, as homologated dimensions (in mainland Europe, don't know about the UK) on all 20vt are both 205/50r16 and 225/45r16.

205/50r16 has 611mm diameter.

if you go aftermarket, you can run
215/40 r17 - diameter 604mm, -1,2% compared to 205/50r16
gives "low" look, doesn't fill the arches if the car is not lowered (imho), doesn't rub the liners/arches (if you don't go crazy with low ET), probably "sharper" handling and less comfortable ride due to smaller sidewall height.

205/45 r17 - dimeter 616mm, +0,8%
imho looks really good, shouldn't make big difference to ride&handling, might catch the liners on full lock (depending on ET, lowering of the car and actual tyre model/shape), probably cheaper/more common tyre dimension than 215/40

215/45 r17 - dimeter 625mm, +2,3%
I'm currently running this size, and I'm very pleased with the looks, ride and handling. Mine's a standard 20vt plus, and compared to previous 225/45r16, the car is maybe 30% more comfortable. Handling: the steering is notably lighter (maybe too much), but that's probably because of me messing with the ET (spacers - Brembo clearence issues, final ET28); it's difficult to comment on the rest as the old tires (Pirelli) were past their prime, but I'm pleased. The speedo on my car is bang-on, it reads exactly s the GPS.
This is quite common dimension on contemporary cars, so the tyres are quite cheap and available.
WARNING: my wheel / tyre combo catched the front liners on full lock (eg. parking), now it stopped. There is 1-2mm groove on the liner's gille aft of IC, and the tyres have a few mm of thread cosumed.

Hope that helps...

Re: Tyre Sizes - 26/10/2021 11:32

I need new back tyres for my 20V Turbo Plus and 225/45 R 16 are like hens teeth and those that are available are expensive and really best for track usage it seems. Has anyone changed to run 205/50 R16 one a Plus model...is this possible, what impact will it have other than being able to find more options? My primary concern is the speedo not reading real speed, is this something that can be altered?

Thanks

It's common to see 205/50/16 tyres on 7.5J Plus rims, there's no real difference in the handling of the car, visually you'll notice the difference.

Re: Tyre Sizes - 26/10/2021 11:41

Visually in a good way....I'm running on standard springs etc.

Will I need to have the speedo recalibrated?
Posted By: 386ka

Re: Tyre Sizes - 26/10/2021 13:05

Nope, no need to have it recalibrated. The tyre's diameter is almost the same.

They'll be narrower than the 225 width.

Guys at local kwik fit seem to think 205 50 16 tyres won’t fit the Plus rims?!?!

No worries....I'm also new to Coupe ownership.

Re: Tyre Sizes - 26/10/2021 21:09

I have Plus wheels with 205/50 x 16 tyres (Contis). No problem at all. Who would have thought that Kwikfit might have it wrong lol.

Re: Tyre Sizes - 27/10/2021 19:05

Thanks....I'm going to see my local friendly independent tyre person this week who doesn't see an issue with 205/50 16 tyres on the Plus. Thanks all for the advice.

Re: Tyre Sizes - 28/10/2021 19:10

Likewise, I've got 215/50 x 16 (Continental Sport Contact 2) fitted to my Plus wheels and they've been fine, although Roger at Power Italia gave me a telling off for spoiling the look

I have plus wheels and have always gone for the 225/45/16 size.

They usually need to be ordered in- and there is not a great deal of choice- but always been able to find them ok.

Regards

Re: Tyre Sizes - 15/11/2021 18:00

Check out mytyres.co.uk They have a choice of nine in the correct 225/45/16 size.

Re: Tyre Sizes - 08/06/2022 10:40

Needed to order new tyres for my Plus and apparently 225/45/16 is no longer available in my area...so what is the next best size you guys would recommend? 205/50/16, 225/50/16 or 215/55/16?

Thanks!

205/50/16 will fit but they're change how the car handles as the Plus rim is a 7.5j and the 205 was designed to fit the standard turbo 7j width.

Plenty of 225 available on demon Tweaks.

Ar...I thought Plus wheel and standard wheel were of the size width (was referring to Useful Info), and now for 7.5J, perhaps I should try harder to look for 225 tyres.

Thanks for the heads up.

From ePER, the Plus wheel is listed as 7J. I took a look at Yahoo Auction in Japan, there's a listing of Plus wheel, in which the pic shown is 7J as well. Attached pics of ePER and Yahoo Auction.

Do you think there are two different Plus wheels various in width?

7j for the turbo, 6.5j for the n/a models, any joy with 225 tyres?

Since you said 7.5J, I was thinking 225 would be more adequate wobble so I placed an order for a set of 4 Bridgestone 71RS 225/45/16, which will be shipped from Japan to Hong Kong. Costed me a kidney rofl

Yes it's crazy shipping costs all over the globe at the moment but at least you've found the correct size tyres for your Plus rims, and to be fair Bridgestone aren't too bad and do last in comparison to track compound.
