I usually use TOYO's but customers specified these.

Just want to find out others experiences, these things stick pretty well but on two of my high hp customer cars 270+rwkw we are experiencing tearing :spank: any one else finding the same?

Interesting, never seen this on car tyres before. Big airplane tyres get it all the time, it's called chevron tearing or "chevroning". Sometimes the tears appear in little ^^^^ shapes other times they are just straight. I think from memory it's cause by the initial touchdown point before the antiskid has a chance to kick in. Unless the tyre starts loosing chunks of rubber or the tears are big you don't have to worry about it. With airplanes that it is :D

Would be interested to know what caused it on car tyres though, the only thing I can think of is the rubber is very soft and the car perhaps suffers from axle tramp...:w00t:

From the pictures that you have posted it doesnt look to me like "tearing", what it looks like is almost certainly a tread join separation.

With almost all UHP tyres the tread is joined on to the casing after the casing is put together, they're not one piece, when the tread is moulded on to the casing the manufacturer almost always deliberately overlaps the tread join to reduce the chance of seperation.

It looks like your tyres are "feathering" at the overlap point where the tread has been moulded.

This usually happens when the tyre has suffered from excess heat build up for an extended period (such as drift or track racing).

From my experience you should be able to wear the tyres down to the belts without the tread letting go (if they are built well) because where it is lifting is only the overlap point, the actual tread join would be further around the tyre underneath the top layer of tread.

If you are worried about it you should contact the manufacturer or wholesale distributor though.

I hope this helps :)

im sure it is moulding issue causing the tearing / separation and have mentioned this to the dealer, unfortunatley they all (dealers) at this stage give blank looks.... tyre re-sellers not experts :rofl: i will send through some pics to B/S HO.

as both cars see ZERO drift or any real excessive abuse that other UHP tyres havent been able to handle.. Not real impressed with them so far.

I was planning on buying some 255 Adrenalin's soon, this aint good news :) Other then the tearing issue (which could be a bad batch or something i suppose), how are your customers and you finding the tyres? Good grip? Last a while? Any info would be great Trent, thanks.

Most tyre retailers wouldnt see this issue very often as it is not all that common in well made UHP tyres, of course Bridgestone are quite well known for their high quality standards. You are best off sending the photos in an e-mail to the importer / distributor who can then contact Bridgestone, they might be able to offer a manufacturers warranty ( I know we normally would ).

But as it is almost impossible to tell whether the tyres have been used in a motorsport application you may not get anything back.

Like I said, you will probably be able to run the tyres right down to the casing without them delaminating, as the actual tread join would still be intact, but the choice is yours. :P

hey your sig looks like our old skyline, is it from adelaide?

I bought it in Sydney from a private seller, I dont know if he was the first owner in Aus though...

It was stock standard when I got it except for the GTR bumper, grille and bonnet lip, cat back exhaust and Volk wheels.

OMG

I have that on one of my rear RE001s. I couldn't work out what it was! Looks exactly the same. 200rwkw S14 which sees a lot of mountain passes but I've never drifted on these RE001s. I'll try and get a picture of it tomorrow.

Anyone else? Should I take the tyre(s) back to Bridgestone and get them replaced? The one with the tear is basically new.

Its not a tear... Refer previous posts.

If you are concerned about it, take it back to the shop where you bought it and show them... If they cant help, call the wholesale distributor directly and explain it.

You may be able to get a manufacturers warranty - No promises though, I dont know what Bridgestone's policies are.

      Duncan's V37.......race car?

      By MBS206 · Posted

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      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.
