ive had two sets now, both have done this. wore the first set down past the tread wear, no problems.

Sounds like its nearly guaranteed if you had two sets do it.

How many kms did you get out of each? Track or street?

not exactly guaranteed....I've bought 2 sets of these and used for 6-18 months of road and track use with no splitting. So on the same logic you could say it is guaranteed not to happen :)

has anyone had an actual failure?

Haha true!!! How good is internet logic!! Im not that fussed or I wouldnt have ordered them anyhow.

I got them fitted last Thursday but have only had a chance to test them out in the wet, so not much of a test.. although they were confidence inspiring and surprisingly grippy in the wet.

Looking forward to some good weather so I can try them out properly.

Going from r comps my car now feels like a luxury barge with these tyres.

i got approx 20 track days out of the 595RS, plus driving to and from the track, cruise days, DECA etc. ~ 6-7,000km over 6 months

they grip well down to the wear indicators, then start to squeal and slide.

went to ku36 and did ~8 track days in 3-4 months, they are down to the wear indicators and have very little grip.

back on 595RSR now, love em. ~6 track days so far, they are wearing well. the grip is the wet and dry is fantastic.

and as i said all four have the 'line' in them this time around.

i do find the RS and RSR are not as progressive as the ku36 tho, when the federals loose grip they really let go. the ku36 seem

to give you a bit more of an indication.

Thanks for the feeback! I plan on using them for street use only. Bit of a worry about them being relatively less progressive, I guess ill find out for myself soon enough.

Out of the KU-36 or RSR which do you prefer and can you please give some feedback about other differences between the two?

old thread, but i'll add my 5c.

I've had this happen on a set of Hankook's and they didn't get much more than a quick burnout or 2. Nothing to worry about as long as the gap stays about that size and doesn't open up any more.

IMO those tyres are unroadworthy, and therefore you qualify for full replacement. The Fair Trading laws are strong and clear. Force them to replace the tyres, as you say its a safety issue.

I've used these for a couple of years on my stagea (circuit and road), and 350z (circuit, motorkhana skids and road) without any problems. might be a bad batch, might be bad luck...either way I would not accept anything but replacement or refund.

I had splits in 2x Nankangs on a Prelude. > Approached Blair's Tyres who are official agents in Oz > One phone call approved an immediate replacement.

Reason:- Even though these Nankangs were rated for high speed, the company felt that expansion under heat oscillating with contraction made the tyre unroadworthy.

Footnote:- Yes they're crummy tyres in the wet, but I applaud their customer service!

I have to replace my RE55s, just street driven no trackwork or hard driving, they've done around 15,000kms in over 3 years and still looking good.

It's really weird how they have gone in recent times with splits around the inside radius on all 4 tyres.

Well i have spoken to Miles at Federal today and asked if they can inspect the tyres on the car?

he said he will send me to tyres and more in south Brisbane (behind my work :) which is good)

Spoke to John (Really cool guy) at Tyres and more he inspected them called Miles at Federal tyres and I get new tyres tomorrow at lunch

The faulty tyres will be sent to federal in Brisbane for assessment by them

It’s not often I get a positive in these kinds of situations

  • 4 years later...

Bit of a thread bump but this was my experience with the 595 Rsr's.

Initially I was happy with the grip and that my understeer issue disappeared but... now.

Front tyres have eggs and don't roll in a straight line.

Left rear shows the tread having ripped away from the tyre, showing the steel belt inside. The belt has torn and there is nasty spikes of metal poking out. It has started to crack around the outside as well.

The seam/overlap join is visible on all tyres. Not exactly confidence building given that the tread is peeling away too.

My suspension guy says this is pretty common with federals and has seen it a bit recently in motorsport. But these tyres would have only seen over 200km/h on the dyno and have never had track time.

They have about 8000km on them. The mould air-release hairs are still on all the tyres. The rest of the time I am mostly stuck in 80km/h traffic with the occasional burst of acceleration.

Hope to swap these for some 4wd tyres instead from the local Federal dealer, and then off-load them to someone else.

Switching to Nitto's for the GTR.

    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
    • Well the articals keep saying a Q50s (Skyline in Japan) with a new Manual gearbox. I like the talk about the new looks with the round tail lights. I hope they bring back the retro look like they did with the Z
