Is your Cerb on 17s, Paul?

Yes, the 17" RL7s work well for me

I have the same question. I’ve just bought a set of RL7’s and am struggling to find a matching set of tyres to fit as per the recommended sizes ie 235/40/17 front and 255/40/17 rear.
The only tyres that show up on Blackcircles are Yokohama Advan Neova AD08RS which I have no experience of. I probably wouldn’t be doing many track days (if any) so they would be for summer use. How bad would they be if I found myself on a wet road?
Thanks

The RS is apparently nowhere near as good as the R it replaces.

You can get some Falken in 235/40.

Or go 225/45 or 245/40.

What's the problem to use 235/45R17? There are many more choices. Does the difference in diameter (2.4cm) makes a lot?

[GermanCerb]

225/45R17 is a good idea - there are lots of choices and you can find several matching tires with 255/40R17 (like Michelin PS4, Michelin PS Cup 2, Pirelli PZero Rosso Asimmetrico and others). Yokohama AD-08 only in RS available anymore.

[Jhonno]

225/45/17 is a very cheap tyre with a huge tyre choice.. It is probably the best solution going forward for a road tyre.

[ukkid35]

Demon Tweaks are listing a dozen 235/40/17 tyres including the highly respected Kumho Ecsta V70A, the less expensive Federal 595 RS-R, and the ubiquitous Continental Sport Contact 5

I can't see any reason to switch to 225/45/17 currently

That will all be old stock sat about for a while on their shelves.. Rubber degrades with age.

Protyre list 1 235/40 a Falken and Tyreleader 3, one of which is the NS2R, the other 2 are budget ste.

As these are 2 of the largest tyre stockist/suppliers (Protyre only stock tyres for 6 months) this is an indication the tyre size isn't being made anymore.

The fact you can get the PS4/Assymetric 5 in 225/45 is enough reason.

When you search you end up with some Japanese (I think they are and that isn’t a bad thing) manufacturers like XXR, Japan Racing, Rota or Bola only.

None of those makes are decent, add in Dare and Lenso and you seem to have picked the worst selection of alloy manufacturers I can think of.

Isn't a cerbara 5x114.3 in which case there are so many Advan, Rays Volks, Enkei, BBS, Blitz, WedSport wheels in 17x 7,8,9j that id sooner buy

It makes no sense to me that you are prepared to be spending £300-500 on tyres to put on budget wheels

Running XXR on my Cerb for 5yrs odd.. Zero issues. Pretty light (9kg odd), cheap, easily replaced, stronger than Spiders, finish has remained good. Running JR on my E61 with the same views.

Yes, they aren't as good as Advan etc, but they are less than 1/3 the price of a used set of the above. If they have a failure I can have one here pretty much next day for not that much.

Lenso and Dare are however, absolute rubbish.

The Kumho V70 is an excellent tyre, knocks spots off the R888R.

I had supply problems a couple of years ago and ended up on R888r but I don't have anything like the same trust in their grip as with the V70. The R888R feel loose under braking especially compare to the Kumho.

I've recently bought some old stock 235/4017 AD08R (to avoid the RS version)

Stored properly (no UV, Ozone, Heat Cycles) it really shouldn't be a problem

To finalize this topic:
On the end I decided for some Enkei wheels PF-09 in 8" front and 9" rear, offset +35 both. Additional wheel spacers of 5mm. Colour is Dark Silver. Tyres are Michelin Pilot Sport 4 in 225/45 front and 255/40 rear.







Due to the nice wheather this year I haven't had too many chances yet to test my combination but for the moment I'm very confident with my choices. The wheels look perfect to me and the tyres are really good.

I bought the wheels on ebay from user "powerweb_us" directly from Japan. It took 1,5 weeks til they arrived at my home via UPS - unbelievable fast. At least much faster then parts from the UK at the moment.

Next challenge is to find out what the TUEV is thinking about the wheels.

Thanks to all who commented here.

I ordered my weds sport wheels on 21st April and still waiting.

[ukkid35]

They do look right on the car, but that's a disappointing amount of wheel weights for new tyres on new wheels

Why 45 profile front and 40 profile rear, are these the sizes that were available or through choice?

very good looking TVR !!!!!!!!!!

Fantastic choice of wheel, significantly better than your original ideas & looks like you got the sizing pretty dam spot on to.

That came from the discussion above. 235/40 is difficult to find - there are just a few choices. 225/45 is standard size for lots of cars so also lots of choices.
The rolling circumference is still a bit lower on the front compared to the rear (original 235/40 & 255/40 is 188,4cm vs. 193,3cm and now it's 192,8cm vs. 193,3cm).
