Those pics of the ZR1... is that tire deformation?

That is because the game looks like real car going around track. Many games have tire wear like F1, shift, forza and of course PC games as well. They will not bother now with updates. It is not too important as long as physics are good but since other have it they should also implement it in their next game

Their tire physics is behind the times, and that is much of the problem with PD. We see this with them being new to Damage systems, and finally modeling cockpits for cars. However, I do hope they get tire deformation.
 
It seems everyone agrees that GT5 has some sort of tire deformation, in the physics engine at least. This would be essential regardless of how basic it is. Having played around with the numbers available in GT5's tuning menus and actual setup formulas what I see is a desire to keep the game with in reach of the average gamer. Some (like myself) are very familiar with racing and the physics behind it, others haven't got a clue. If the Gran Turismo series gos into a tuning system that is fully realistic many would get lost in trying to tune 10 dampers and springs, 8 suspension geometry measurements, and all the other variables involved. Though I would love it if PD decided to make all this info available and tunable.

Have you played other racing sims with actual tire deformation? Just curious.

Yes I have. But just because you dont see a tire being compressed from lateral forces on a turn doesnt mean that its not happening lol. And yes GT5 is missing a plethora tire deformation variables 👍.

That's not the only thing that makes tire deformation their are several technical things that allow a bigger picture on tire physics.
 
If we had tyre deformation I'm sure we could alter tyre pressures aswell.

Having played Live For Speed a lot I can tell you you can feel the sidewalls moving around every time you turn. You don't feel that in Gt5 sadly.

There is hardly a consensus for it, and a lot of evidence against it.

What GT5 has is tire grip and heat modelling. The tires overheat, then lose grip. And this heat is dynamic and changes as you push harder or ease off. This much, at least, is better than what we had in GT4, which regarded heat and wear as a single variable.

But tire deformation, skipping, scrub, flat-spotting... are nowhere to be found. Ever find yourself wondering why the front tires are going ka-thumpa-thumpa-thumpa after a two hundred foot skid on locked brakes in GT5? Me neither. Because it doesn't happen.

The lack of tire deformation modeling is also seen in how grip changes linearly between "comfort", "sport" and "racing" tires, in which the difference in carcass stiffness is not modelled between comfort tires and race tires or even between comfort tires and sports tires.

It's most clearly seen, however, in how cars act at the edge of grip in transitions. You have none of the squirrels you get from running on soft-sidewalled street tires at their limits... none of that "squidge" as your alloys come two inches closer to the pavement. There's also no juddering or skipping as the tire bounces across the road. Except in karts, but that's because they're solidly suspended.

I'm one of those who loves GT5 and still plays it to this day, but tire deformation and tire modelling overall are still behind the competition. But that's a minor worry, it's still a lot of fun to drive around aimlessly enjoying the rest of what GT5 has to offer in terms of the experience.

I have only ever seen the entire tire respond to outside forces, rather than only a portion of the tire. The most common scenario would be riding the rumble strip and either the suspension compensates (resulting in the majority of the contact patch being lost, visually) or in brief instances the tire passes through the rumble strip in the form of a visual glitch.
 
No, it doesn't exist. At best, the tyres will fall in to the road in terms of a visual glitch (like DDAAAVVVIDD said) - which looks like deformation.
 
The picture of the tire should be taken on the track not from the garage. It could be different models. The cars tires could show this just in the garage since it is a static object.
