View Full Version : Blown/flat tyres or suspension failure? Feature or Bug?

Was doing a tourist day online with the BMW 2002 Turbo. Came over the Adenau bridge at pace, got on throttle and slid the backend a bit and felt/heard vibration in the car/FFB. Switched to outside and one rear tyre was going up/down (suspension travel) like it was flat on the same spot when I rolled the car forward a little, but was visibly ok and the telemetry still showed the tyre as inflated.

Later while racing I had someone mention they had 2 "flats" in the same race in the Escort.

[EDITED]first time Mechanical Failures were on, second time off.

Is this supposed to happen or is it a bug?

My money is on a BUG! The % of winning that bet would be good odds !

Drove the 02 around the Nords quite a couple of times since the patch is out and only had one occasion in which the front left tyre ran flat for obviously no reason. Booked it under bad luck. I've driven quite a couple of other cars around there at pace including the Focus without anything like this happen.

If the HUD was showing pressure in the tire then it wasn't flat. You say the whole wheel-tyre assembly was bouncing up and down? Did it appear to be moving around a normal position or was the car sitting at an odd angle. It's sounding a bit like the suspension model crashing into an inversion of the geometry.

Can AI drivers cause issues the suspension model?

Know they don't run the same physics as the player (so answer is probably no) but I had an AI driver (Aston GT4 or Hybrid) blow tire/suspension over the weekend at Le Mans; looking at track map it was right after Arnage on the straight before Proshce curves.

Seemed very odd; on the straight the AI guy just pulled off hoping around on three tires. Chalked it up as a blow tire or DNF for the guy which was pretty cool to see in the middle of a simulated 24hr.

Anyway, got in on video: https://youtu.be/P52PUsMqUgg?t=26

This is probably a n00b question, so forgive me but... how can you tell when your tire is blown? Is there an indicator of some sort or is it just feel? I haven't had a situation where I've known a tire is blown so I'm wondering if I'm not recognizing it or if I've been lucky.

On the HUD where it shows the tires, a blown one will have the wear indicator (how much green is left) all the way to 0. In the telemetry screen, it will show the tire pressure as 0.

You can turn on an indicator for the tyre wear and temps in the HUD. Besides that there's a whole telemetry overlay that will give you even more specific infos.

Right, I've got that on and I've seen temps change and tire wear but what does it look like when one is blown?

BTW, the key part is the tire pressure at 0.

I have had the game since release played it daily and never had a blown tyre and i've tried many times to do it but not since patch 8 , I always thought you couldn't blow the tyres .

Likely depends on the cars you drive. I don't believe they are that pervasive with the modern GT tires unless you drive them past being worn past the wear indicators (if you mainly drive the GT3 or LMP cars).

Thanks i'll try some of the older cars , I mainly drive all of the LMP cars and there the one's i tried to blow, I'll give it a good go tonight and try amd make them go pop :) I will report back.

Rear axle on that side was going up and down if I rolled the car forward or back, think of if you had a flatspot half the size of the entire wheel. There is a bumpy section going up the hill near Adenau, that may well be what it was. I just would have thought if it was suspension it wouldn't be triggered by rotation like that? There was still pressure in the tyre, so I guess some sort of axle or diff or driveshaft failure maybe? Might account for the rotation aspect? (no idea what's possible with the damage physics)

Got it. Thanks! Never managed to do it.

Had a blown rear tyre on the 66 mustang in a first corner collision with the AI yesterday,was very suprised as I've never had one before in 400hrs of play.Didn't look at the pressures but the wear indicator was flashing red when it blew.Very cool feature if it happens from collisions.

Something is strange in the StanceWorks DLC. I had this yesterday in an online race with the Radbul after two corners on the front right! Default setup and all. Same happend with 2002 SW the same evening. Never had this before, now twice in one evening... And yeah, on the front right of the Radbul? If any tire should blow it's one of the rears, and not two corners into a race.

Edit: no contact or anything like the post above, just drove around the first corner of Laguna Seca.

I also had my first blown tire since release of the game. In the BMW 1M SW in the second to last corner at Cadwell Park. I just drove over the curbs on the outside of the corner and the front left tire blew. I think it was in the second lap and tire wear wasn`t bad at all. Tire pressure was 0 after the tire blew.

Did you change anything in the physics in the latest patch?

^^^ this happened to me last night in practice on the BMW Stanceworks 1M, first lap on the new DLC track tyres all green in the hud then suddenly noticed the front right hud empty which I assume was indicating a blown tyre but handling was fine, I had been sliding the car about a bit but no contact with anything and don't understand why the handling was unaffected. This was also with default set up.

Edit: the only thing I can say is I was pushing the car so maybe that caused the failure? Just not as other people had mentioned seen one flat before patch 8.0 may just be a coincidence.

Last night BMW 2002 Silverstone national practice session , I left the pits done a steady out lap on the second or third lap just after the first corner after start finish line my ffb felt strange a little wobble side to side and my right rear tyre turned grey

Edit, On vrhive it said the rear right tyre was 98% worn.

I had the bug on a Ford Escort on Sonoma(short?), 1 time.

The tire wasn't blown. It was visually ok.

It was visually ok for me as well i carried on driving and set my fastest lap of the session only thing that felt wrong was my ffb it sort of felt like i was constantly driving over cobbles.

I thought that i could see it yesterday. I don't have a screenshot, but the tire looked flat, compared to the others. :confused:

Tyre definitely looked flat when it blew on the 66 mustang :confused: next time it happens I'll take a screen shot :)

SMS always talked about tire flat spot and blown tires but i don't remember anybody in the last 8 months having one though. Good to see that that they finally turned this on. I hope they don't over do it .

I had a landmine bug today. It blown one of the tires. I would feel it through the FFB. You could clearly see how the tire was deformed.

I'll try to post the replay of it.

Flat tyre with an old Escort at Nords. This time I think I noticed what caused it. Came out of the caroussel and scraped the floor with the left front (bottom) and immediately noticed something "broke". The indicator of the front left tyre was still green at this point but a couple 100 meters later it got insta red and the car became absolutely undrivable. Couldn't use replay to watch it from the out side and make a vid because it happend online. I'd guess about the same must have happend with 2002 before because it was the same part of the track.

Oh a puncture. Not had it happen myself but seen a couple of posts on something similar!

Yeah I've had a few.. same thing with the BMW 1M stanceworks too. The Nitto 05 tire can puncture.. or it's some kind of other bug because tire pressures were still showing full pressure. Could be the suspension collapsing or something.

This happend to me on Nords. This time it started before the caroussel already. As far as I noticed I didn't hit the curbs to hard or anything like that in before. Steering became more shaky the longer I was driving and finally the left front tyre ran flat but I was still able to finish the round as the shaking stopped getting stronger at one point so it was bearable. Looks like a "creeping flat" as we call it but I don't know what could have caused it. Maybe a flat spot from overbraking, suspension damage I didn't noticed or simply a faulty tyre? I really don't know.

Happened to me three times at Oulton International... Once in the first lefthander after going down the hill after the starting line - fresh out of the pit. Flat front left. I had just lowered the rideheight by 10mm so I thought that maybe caused the issue. Readjusted it back to default. Then in the race, it happened two more times, each time exactly after 4 1/2 laps of driving. Had no collisions, didn't bounce of curbs, didn't lock up wheels during braking. Once front left, once front right.

I DID raise the tyre pressure to 1.94 and adjusted camber by -0.1, but the temperatures looked normal and stable at ~60 across all four wheels.

In a way, it's a nice handicap to offset the obvious advantage the 2002SW has in it's class, but not even driving carefully and rather slowly protected my from getting the second puncture.

Was this today with the 9.0 patch or with the previous 8.x patch?

9.0 seems to have done something about this. I just spent some time at Oulton Int, hurling the 2002SW into corners in great clouds of smoke, deliberately locking up wheels. Slow as hell, fun as hell, but no puncture in the time I tried. Before, I would have had at LEAST one puncture doing this.

Last night I had 2 punctures on the same wheel in one round.
The car was the BMW 2002 Stanceworks. Patch 9 installed.
I am sure this is a bug.
