Tyres

[Lonestar]

215/45ZR16 (front) and 245/40ZR17 (rear) are the original sizes on my 1999 car.

ok, but what are the best alternative sizes if I cant get the oem ones?

[Silver Surfer]

225/45/16 front and 255/40/17 rear will work

Please note that even with the same tyre size on the sidewall, the actual circumference is different depending on the tyre structure and manufacture so using different size from OEM one may trigger the TCS under certain conditions.
For example, you may find that going through the small roundabout is fine but when driving at moderate speed through mid – large roundabout, you may activate the TCS depending on the tyre F/R combination and the tyre manufacture/structure.
Personally, I don't like the TCS on non-DBW model so I will disable it.

By the way, there are lots of misunderstanding on the speed rating.
Whether the insurance company knows it or not is a different story.

First, the ZR is a speed category and not the max speed.
It’s also from the ancient standard so not much used these days since the introduction of the new standard.

While many people thinks that the speed rating is showing the max speed limit, it’s not that simple.
It is the max speed under defined conditions (defined increments of speed/time under defined load, etc) and one of the key condition is having the tyre loaded at its max Load Index weight while testing it.

So, even if your tyre has speed rating of W (270kph, about 169mph), it doesn’t mean it’s not safe to use on our NSX as the Load Index will be around 86 (530Kg) and this is per tyre.
Again, the insurance company may ignore this fact……

If you have a chance to visit the tyre manufacture’s tyre dyno, you will understand how thoroughly and strictly your tyre was tested and also recognise the importance of the tyre maintenance.

Looks like Michelin have decided not to do any tire that fits 215/40/R17 and 255/40/R17 (Original 02+ tyre size). So after hours searching the internet it looks like you can get Bridgestone RE050's but I think in one of the sizes the tire is a run flat. Or Yokohama AD08r's.

I need to get this sorted before Euro trip in May.

AD08's are supposed to be a good tyre if you don't do much wet-weather driving...not sure how the -r differs to the original though...

[lotusolly]

I have the AD08-R's fitted and not noticed any problem in the wet.

I had the non R version before and cant say I can tell any difference.

I am running Toyo T1-S proxes on the rears ... Thought I would check them out ... These are similar to their highly rated Proxes R's.

I have always run b'stones on my NSX so this is a big move for me. The RE050's can be gotten without being run flats afaik

Re the Toyo's so far so good ...

I've been pestering our European tyre supplier for Michelin Pilot Sport Cup 2s or Toyo R888s for ages now but getting 215/40/17 and 255/40/17 together in particular brands / models is impossible! I'll most likely be going for AD08Rs as I don't really want different tyres on different axles.

After only 3,500 miles my Toyo 888R rear tyres are now worn out 😳
So I thought I would try the TR-1's on the basis of what nobby thinks of them so far, they certainly look good and at just £125 for the pair 👍 I can't really go wrong, hopefully good for 10,000 miles at least now.

First impressions this afternoon are very good and with the super sticky 888R's on the front for good sharp turn ins I'm hoping this will be a great combination.

I've no idea how you have your chassis set up but to chew a set of rears so quick youre either hard on tyres by way of driving style or they were (IMHO) way too soft for road use.

I had F1's do 18k on the rears, Kumho's that did similar ad offered stiffer sidewalls, and current AD08's have covered 10k with plenty left to go ...
