What do you think about the new tyre model? (Update 0.5)

My initial impression after playing with the update was that the tyre model was improved. Where as the FFB felt a a bit vague/numb before, now it feels much much quicker to respond to my inputs and it gives me a much better feeling of the car. I also observed that weight transfer happens faster and was more sensitive. While drifting I am able to transition more quickly and aggressively especially in the Drift-spec E30 M3; before I felt that it was too sluggish during weight transfers. Low speed oversteer seems more controllable and catching slides while grip driving also seems easier to me but I attribute that to the improved FFB and better feel for the car.

I also like the new tyre heating model. The tires have significantly less grip when cold; before I only had to brake and corner about 15% earlier/slower right out of the pits, now you will go straight off the track if you try that.

 

I have a much easier time with throttle control during a slide/drift, feels like the car doesn't just slip into an unsavable slide anymore unless you just really screw up.
The FFB feels great.

My friend has a 180sx and drifting that thing is heaven... Nearly stock suspension too, normal tires, itll slide all day without spinning.. Cars aren't driving on ice, and I feel like the tire model is a step in the right direction.
We both feel it's still too hard to drift the E30, but it is a different kind of car, and we are still getting used to the game.

 

i find heavy braking is harder..more twitchy

 

can definitely feel the front end squirming around under hard breaking and its amazing...

 

Hate to say it, but I had to switch ABS on because of it > ~ <

 

For me the new model is a big step forward. I have a better understanding of the car under all circumstances.

 

I'm also really happy with the tweaks. Yes, AC feels in some ways a little closer to Forza (without the stupid tail happiness and impossible to save slides in sim steering mode) or GT, but that's fine.

I've never understood the "simracing must be a challenge" mindset embodied in rFactor and iRacing. Of course cars are inherently stable until you take them right to the limits, otherwise the only people who could drive them fast would be the 0.01% with alien skills.

I was driving the Z4 GT3 last night, and when you start lapping it you just feel on rails. But then you realise just how much faster you could be going and you keep pushing and pushing. A gentleman driver in a GT3 endurance series who has to keep one on the road for his 2 hour stint doesn't want a flighty twitchy roller coaster. He wants something stable in which he can lap within a few seconds of his professional codriver without risk of spinning every lap. And that's exactly what the Z4 GT3 feels like.

 

Ive only really tried the 458 in the supercar challenge but i felt the car understeered quite bad mid corner/corner exit.

Im not a numpty at driving it either i managed to do the 1'53 challenge at imola.

Im going to have another go today and test it out.

I did try the f40 at imola and was getting 2'02 which is only 1 second off my best.

 

Why are you so slow with f40? If you can lap 458 in 1:53

 

Oh, thats using 90's street tyres on the f40.

 

Ahh ok

 

Last time i checked i was 3rd fastest on rsr, im sure im not now tho.

 

love the grip of the front wheels feeling I'm getting from my Fanatec CSR wheel in heavier cars!

 

Posted this in another forum. might as well paste it here:

I tried the Z4 GT3 today, as it's the car I know best and have been using to do hotlaps on RSR and Rivali Tempo. So the following comments are about this car only, other cars might have reacted in a different way to the tyre model update:

- Under the limit, I see no big difference, but the FFB is better now in my opinion. You can feel better what's going on.
- At the limit the car is still twitchy as it should be, but it's more predictable than before (probably because of the better FFB?), I like it.
- Under combined slip (trail braking or acceleration in a turn), the car has definitely less grip but because it's so predictable, it's a joy to drive.
- Overall, the car seems slower now, I did a 1.43.714 with it on Imola and that's around 7 tenths slower than my PB with AC 0.4. I guess, I will go a bit faster, but overall the new physics seem to be slower with this car.

In a nutshell, I like the new tyres a lot. It's an improvement on something that was already great.

 

Based on having tried the Fiat 500, 80's M3 touring car, the M4 GT3, and the F40...

Low speed grip appears much improved all round, so slower corners (such as, well, all of Magione) feel like they suffer from a lot less good ol' low speed sim slide. The little 500 now feels a lot more like what it is - a nippy supermini that's designed to not kill you when you go shopping. The front ends of everything feel a bit more planted than they did, especially the F40. Haven't really noticed the decreased forward / backwards grip change if I'm honest. Haven't had time to check it properly, but it also feels like slick and semi-slick tyres take a bit longer to get up to working temps and pressures than before, but actually getting the things into the right working range via setup is a bit easier, which also feels like an improvement - it took a couple of laps of Magione to get the 500 on semi-slicks through the two third gear right handers at the end of the straight at full pace, whereas it was one at most before.

My only concern is they all now feel a little bit to easy to save in the event of losing the rear. I managed to recover from a couple of really wild slides in the M4 GT3 which, IMHO, really should have been unrecoverable. The rear seemed to pick up lateral grip very rapidly indeed as the speed dropped despite what felt like a very terminal slip angle.

I'd moan a bit about the 80's M3 touring now car feeling decidedly odd (struggling for a way to put it, the best I can offer is "unnaturally neutral"), but I think some of that's down to carrying over the setup from previous build and it just not translating. Will give it a bit more effort later see what it does as this one's probably my fault. Most things are.

 

I haven't tested for hours so can't comment on the fine detail, but I've been driving the 1m and it might be me but this car feels great right up until you start to understeer, at which point it feels like your front wheels are now connected to the steering column via spaghetti. The ffb drops off in a very unnatural way imo. There is a step as the car begins to "push". This feels like an exaggerated effect for people that want the ffb to "tell them what's going on", and doesn't feel realistic to me. I'd expect aligning forces to drop sharply if I go to full lock really quickly on a wet road, but not minor understeer on a dry surface. The car feels broken when it happens.

 

F40 felt the same to me.

Zonda felt the same to me, but I couldn't match my time at Monza in it.

BMW M1 feels properly strange. I've driven one IRL, and the sim car definitely reminds me of it, but the hopping around under hard braking and turn in oversteer seems a bit strange? Maybe its me.

Still enjoying the sim.

 

I did 15 laps on monza special event and my feeling says that the tires loose grip now more realistic

 

Indeed an improvement. Better FFB, better transition between traction and grip loss (in turns), low speed behaviour is better etc... more realistic behaviour overall i would say.

 

Well done. A real step in the right direction.
