From just watching this video I decreased my lap time by 5 seconds in my Lotus 3-Eleven at Mugello! Thank you so much this video has helped a lot! I kept all my cars PSi’s at 33-35 always to get to 38/42 like families suv 😅 I know now that our cars are simply not race cars lol
You said @2:50 that if the edges are hotter than the center, the pressure is too low, but you also say @3:19 that should the inside edges remain hotter than the outside or vice versa then it's not a pressure issue it's a camber issue so which is it?
In the first part, that's edges plural--both inside and outside. Essentially the tread doesn't have enough pressure and the edges are doing more work. For the second part that's just one edge (inner OR outer) which is usually a camber issue.
Oh okay well on the second part you said "edges" plural then "or vice versa" meaning outside or inside so both and it didn't make sense for my brain gotta be one or the other, tire pressure or camber
@@1Wheelchairmaniac Thanks for letting me know it wasn't 100% clear. I checked the video and all sounds right. We use "inside edges" (plural) for camber which might be confusing--it's talking about either one of the inside edges of tires on an axle. The vice versa is referring to scenario 3 or 4 below. Here are the scenarios listed out for one tire to avoid any confusion on plurals: 1. Inside and outside edges are hotter than middle - low tire pressure 2. Inside and outside edges are cooler than middle - high tire pressure 3. Inside edge is hotter than middle and outside - too much negative camber or maybe just the right amount if not too much hotter. 4. Outside edge is hotter than middle and inside - not enough negative camber And remember to check the tire temps a second or two after a corner to avoid too much negative camber. Let me know if you have any more questions.
@KeystoSpeed I do have one question, having trouble knowing what to tune first. I watched all your videos in this series, is there any order you need to go in like tuning springs before tire pressure cause wouldn't soft springs give you more contact patch and you'll have to re-tune your camber?
Good point! I've started recommending a wider range of temps in the new Motorsport. The latest ForzaTune apps are also using a wider range of recommended values. The approach of "shoot for 32-34 PSI when warm" seems to fall short with the new physics. Thanks for mentioning this.
You're welcome, Clinton - and thanks for using ForzaTune. You might be interested in the new ForzaTune 7 if you haven't already seen it: ua-cam.com/video/pF3Q_lNBorY/v-deo.html
If I don't race in simulation mode, does tire pressure matter? Couldn't I set the pressure to optimal pressure (31-32) and it will stay like that throughout the whole race?
You still want to use telemetry to target the 33 psi range as a baseline, but feel free to go from there. Softening the springs and ARBs first is the biggest change I make.
I'm playing Forza Horizon 4 and 5, and I have to say, there really is no corner-cutting. You have to learn how to make the right adjustments, or the game won't be any fun at all.
Took me a while but all mine stay the same temp now except the front wheel around turns is slightly different but coming out of the turn they all even off around 180-190f on my sport compound so the numbers all being the same i assume means i have good contact patch ???
It's pretty similar, with the exception of the tire compound and temp ranges. For more check this section of my tuning guide: forzatune.com/guide/the-fully-updated-forza-tuning-guide/#tires-how-to-choose-the-best-pressure-and-compound where I make a specific note on Horizon and tire temps.
Best tuning explanation on UA-cam, I recommend all forza players to watch all of the series.
Yes, Watching for Forza Horizon 4. Works well, But not good as Motorsports

Thanks for giving temps & pressure in F & PSI. Even leading with those first. It's much appreciated to this Yank 🇺🇲 mate. 👍
What need the stock and sport pressure be at 🤔🤔🤔🤔🤔🤔

@@KeystoSpeed okay that helps and puts it all into focus a little better

Does Fh5 work the same?
My psi is like 24 but if I increase pressures the middle gets hot I thought psi needs to be 30 plus

@@KeystoSpeed you answered comment on 6 year old video! Legend you deserve a sub
The video says run a full lap in order to reach optimum heat but what if the track is a short tight circuit 🤔. For example Monza Short Circuit
The tighter turns may generate tire heat to help offset the shorter distance. But it won't hurt to run another lap if the circuit is very short.
Gallium Racing School thanks for the help btw I love using Forzatune 6

Whats the optimize pressure for sport tires ?
No matter which compound the general idea is to still target 32-33 PSI.
In R class I set my tires to 27 psi when it heats up I checked my telemetry and it is 31-32 psi
If I don't race in simulation mode, does tire pressure matter? Couldn't I set the pressure to optimal pressure (31-32) and it will stay like that throughout the whole race?
Thanks for the question. The pressure and temp should change regardless of difficulty. If in doubt you can pull up the telemetry to check.
Do I aim for 32-33psi if it is raining

True! ForzaTune Pro helps get most of this done automatically, but it's always nice to know more of the "why".

Can you tune this way on forza horizon ?
