you mean these?

I haven't used them, but since they are semi slicks you can assume they are:

Excellent in the dry once they are warm

Poor to dangerous in the wet

Noisy

Tramline

Quick wearing

Have not used them either but ridden in 2 cars fitted with them..

Can agree that they are excellent in the dry, don't really need warming as they aren't a proper semi slick they are a road tyre which is the closest u can get to a semi slick. they have tread wear of 180 or 200 i cant remember. precisely but i think it is 200.

On that point its also worth mentioning that they are the replacement for the rt-215 which was recognized as performing to its best without warm up

They are are definitely not poor in the wet, once again i have not driven on them but driven along with a few cars fitted with them and on a damp/not very wet surface they are way better than normal top of the line sports tyres like t1-r and sport maxxs. I would say that when they road is very wet ie. a pool of water covering the road they are not as good as a regular all weather sports tyre but still not poor or dangerous like falken 326s for example can be

Edit:removed image, and this should really have been posted in the tyre thread.

I have 215's on the front and 615's on the back at the moment (GTSt)...

They aren't noisy, they don't tramline badly and they are actually better than 'normal' road tires in the wet... BUT the 615's look to wear much quicker than the 215's... I have done 2 track days, a motorkhana and about 4,000 road kays on them and the 215's have plenty of meat left whilst the 615's are almost down to the indicators... however they are on the back and responsible for putting the power down so a little hard to get an accurate comparison

one thing to note though, with the stiffer sidewalls they do transmit much more of the little bumps and cracks in the road than normal road tires... can be annoying on bad roads

great cross over tires but if your after good times on the circuit get some RE55's or equivalent

rt215 was perfectly safe in the wet (if you always remember you are in a turbo car) so assume the RT615's are similar.

I got about 12,000km out of my rt215's with still a few more km in them. That's not quite up there with your 20-30,000km of your average tyre, but if you don't do a heap of km each year, fair enough.

The RT-615 manage to incorporate the negatives of a proper R compound, ie harsh ride, noise & poor wear on the track without compensating by offering the same amount of grip as a proper R compound.

In short they are neither Arthur, nor Martha. IMHO if you want a track tyre get a proper track tyre & don't muck about with these things. If you want a road tyre, then get a good road tyre.

Problem is a good road tyre still is no good for the track, and then you have to lash out the cost for the RE55's or the like, good spare set of rims, swapping them each outing, etc. So it's either cheap-ass road tyres (which can be dangerous), although are probably driven on 98% of the time, or spend good money on both... which is getting close to $1800 just for 2 pairs.

A compromise tyre would be great, but of course the characteristics of one make it unsuitable for the other.

I currently use these tyres (275/35/18's) on my GTR as street tyres. Very good every day tyre. Wear is good, traction is good and price (surprisingly) is good. I was originally using Yokohamas AVS sports which were hiddeously priced - around $600-00 per corner. Thought they were crap by the way. The Azenis 615's were about $370-00. Grip level (especially when new) is awesome. They are wearing slightly quicker than standard, but at the price I don't mind so much. Don't seem to be affected by the constant heat cycling like the 215's used to. I would recommend them as a street tyre. If you are considering for the track, I could name plenty better.

Gotta say, the aggressive tread pattern looks pretty fat on the car.

I've had the 215's on my stock rex for about 15,000km's - and the car has had some rough treatment - and they are still ok.

Not perfect but they are not ready to chuck yet by any stretch of the imagination. And for a street tyre they are by far the best overall tyre I have used (great in both dry and wet). I'm planning on replacing them with the 615's as the 215's have been so good.

lol, i was gonna say id almost buy em coz they look cool :P

Im yet to pick some tyres for my GTR, these seem well worth looking into. Ive used RE55s, and absolutely loved them, on street and track (i hear Yoko AO48R's even sh!t on the RE55s) but the bridgies definitly needed heat in them!!

I have a local route id drive and usually the tires would be warmed up at the end of it, but once i went out and didnt take into account the colder than usual temperature of the day, and upon finishing my usual "warm up course" i threw her semi hard into a corner i normally have no probs with, and she understeered straight up onto the median strip and into the flower bed, lol.

:dry:

  • 2 years later...
i have a set on my car and im very happy with the grip in the dry.... on the wet..... a bit iffy.

was very happy with at the track..

wear life unknown.

Thanks for the feedback.

Getting a set on Sat so will post my thoughts later

    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
