Hi all

Forgive me if there is a thread already somewhere covering this, I had a quick search but couldn't see one. I need to get some new tyres for my 1999 C34 RS4S which is sitting on the stock rims at present. I went to get some KU31s only to be told they are discontinued. I went to another store and was recommended Dunlop LM703s which seem to get mixed reviews. Any recommendations as to tyres worth looking at?

Thanks

Tim

how much you wanna spend?

In all honesty as little as possible. I had $700 in mind as that was what I was quoted for the KU31s a while ago. I can get the Dunlops for about $440 as they are on sale at the moment. But I'm open to suggestion.

On my 2000 C34 S2 I have Michelin pilot sport 3 from bob jane, they did a deal I think I paid about $185.00 ea. I was looking at the Kumhos as well, did a bit of research and I'm glad I went for these, we have had some pretty serious rain in the mountains in the last week and not once did I feel I was getting close to their limit even with some spirited driving. I probably have about 10 000k's on these now, I did fit adjustable upper control arms to reduce my neg camber on the rear as I kept scrubbing out the inside edges of the tyres, nice even wear now. Hope that helps, Regards Craig

Is anyone familiar with Pirelli Dragon Sport tyres?

I recently had my car serviced and Chris (mechanic recommended by Jez at DVS) noticed that the inner walls of my tyres were cracked.

I went into the Bob Jane tyre place next door to see what 235/40 R18's they had in stock for immediate fitting (Friday arvo before the long weekend).

They had 3 choices: a cheap no-name or a cheap Yokohama (not Advan), both about $120ish, or Pirelli Dragon Sport @ $169 ea.

I couldn't find any online technical info or tyre tests for the Dragon Sport, but they were fresh (2016), W rated, had a square profile, and big wide grooves that look like they'll drain well.

Mostly in preference to the other two choices, I bought the Pirellis.

I've only driven on them a couple of days; mostly sealed, winding country roads:) Now they're scrubbed in, they have enormous dry grip. I've only pushed them a bit in the wet and haven't found their limits. So top points for lateral dry grip, and wet grip looks promising.

The downside is, while they put a full 235mm of tread down, and provide good road feedback, they don't deliver quite enough steering precision as I'd like. I think sidewall flex is an issue. On the rims at 38psi the side-walls bulge out and look a bit donutty.

I've combed the interwebs and can't find much info except irrelevant 2010/12 reviews of an old Pirelli Dragon (not Dragon Sport) tyre with a completely different tread pattern, and a press release saying the Dragon Sport (like what I've got) is a new tyre developed and manufactured in Pirelli's new plant in China. Which explains the relatively low price.

The Pirelli Tyres Australia site comparo charts show them as outperforming the P Zero NeroGT and up there with the P Zero Rosso. I know it's only manufacturer's info, but relative to their flagship performance tyres, Pirelli seems to rate these tyres highly.

I'm enjoying them in the dry and the wet. The car tracks straight (the wheel alignment probably helped) doesn't wander or tramline, and feels more planted as speed increases. They're also fairly quiet as far as I can tell over the Fujitsubo exhaust.

They're predictable in dry cornering, feel secure and fast in the wet, and provide a nice amount of higher frequency road feedback. The only downside is slightly imprecise turn-in - like a bit of tyre roll is absorbing some of the steering feel.

On the whole, I think I might have stumbled on something pretty good. Slightly stiffer walls and I'd say they were magic.

I'll try them at higher pressure for a week or so. Meanwhile, has anyone else tried the Dragon Sports? Any feedback? Comparison with Pirelli flagship tyres? Opinions?

OK, I've done a few hundreds of kms on these Pirelli Dragon Sports tyres and they're a bit nice.

THE GOOD

They like 45-48psi which improves their turn-in feel.

In the dry they're grippy and predictable.

I don't push hard in the wet since an 'off' on my narrow winding country roads would be a disaster. But these tires give me a lot of confidence in pushing through corners 40-50% quicker than on the tyres on my car when I bought it - Nexen 5000s.

And they feel vastly more reassuring in the wet than the Falken FK-452 tyres I had (along with Bilstein shocks and Whiteline swaybars) on the F6 Typhoon.

They can be a bit resonant on certain road surfaces, but nothing compared to the Fujitsubo cat-back.

Overall these aren't just good, they're 'great' sticky tyres and cheap as.

THE BAD

Apparently, Pirelli doesn't want you to know ANYTHING about these tyres. So the only info online is some hurried reviews from a single PR event in China that got rained on, and some meaningless marketing slobber written by retards with zero knowledge of English, who don't know the difference between a tyre and a condom, and should be fired for abuse of language and customers ...

"The pleasure to be sporty. The indulgence in Pirelli safety." And "Enhancing handling performance for sport driving on wet and improve safety."

Shit like that prevents thinking people from buying their products.

    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
