Custom wheels give all 4 tyres the same width.... changes grip and balance

Last I checked in on the issue, it was a +1 or +2 wheel size issue. Are you guys now saying that even stock sized aftermarket wheels have this bu associated with them as well?


This issue affects all custom wheels, so far on the GT40 '66 seems to be immune to the loss of tire width I photographed the car to be certain it even retains the exact same tire tread. The GT40 though exhibits issues with changing wheels as the car becomes unsettled much easier but it's faster than when on stock wheels. So PD is holding information from us on the effect of custom wheels on cars with original suspension as with my GT40. So it's seems that some wheels are lighter than stock wheels thus leading to less unsprung weight and the suspension was built for the original wheels giving you way too fast in extension for the lighter wheels. Give it a try and you'll see with aftermarket Torx Wheels the GT40 is very unsettled and leads to you having to drive on edge but somehow it's quicker as you can rotate the car much easier than with stock wheels.

For now stay away from custom wheels on any car, bug causes every car but the GT40 to have for front wheels at all points. I got the complaint thread to link the issue to their first page so hopefully PD notices it. I don't like losing grip because I want to change my wheels and hopefully they give us the information we need when making wheel changes like weight loss and or increase and wheel width for both front and rear wheels.
 
Here is how PD should fix this issue: let us increase the width of our custom wheels!!!

This might actually be implemented, like I'm hoping. We are in the first month of the game, you know.

Just confirmed for my CSLs. The width difference is there but definitely not as noticeable as the example in the OP.
 
He says "people that have no idea about it, will hate". I'm interested in this.

Also English is not my native so I have big troubles with "reading between the lines".
Because it messes up the car's balance.
 
If I go and buy a new set of wheels for my 996, am I going to replace the 8" front and 10" rear with 4 x 8" rims?

Of course not. I'll buy a set of new rims of at least the same width.

When you replace rims on your car in the game they should be the same width as the original wheels.

This times 1000!!! I assume it's a bug that PD somehow managed to miss. I mean, it has to be a bug right? How anyone can fight this is beyond me. Why on earth would I "upgrade" my rims onto smaller rear tires that screw up the balance of my car? Personally, I don't care about changing tire width as an option. I just want my tires to stay the same regardless of which rims I put on them.

I guess for the time being I'll just take all my rims off and pretend they aren't a part of the game. Please PD this needs to be fixed now!
 
Dramatic much?

Yeah, I know it sounds like I'm being dramatic, but you have to admit it's kind of disappointing. I'm sure it was not intentional on PD to miss this when they have such a huge game.

It's definitely not a game breaker (well, kind of), but it will hurt the game for a while until they get it fixed.

Did this yesterday, and just as well too other wise all those rides I brought from the additional seasonal credits would have had new rims too and it would have taken ages
 
Thanks to the guys that found this out, now after spending hours choosing custom rims / colors I have to switch all cars back to stock haha. I wouldn't be so annoyed but why the heck can't we paint stock wheels :(.
 
Does this only happen when changing the diameter while installing aftermarket wheels? I've noticed quite a few times that a staggered setup will remain when using the original diameter.

Edit: Upon further inspection, it only appeared that way since the cars in question didn't have a clear view of the rear width. After testing, I can confirm what everyone else has said.

It's an issue with high performance cars, as I can see. FF cars or low performance FR and MR cars don't seem to be affected much since they have equal width tires.

I was hoping this affected only certain high performance cars, but it seems every single car is affected. I bought an SRT Viper today and when I changed the wheels, it seemed normal in GT Auto, but in the garage, the problem was very noticeable. The rear tires were the same width than the front ones.

I'm sure this is a problem that won't be ignored by PD. Hopefully we'll see a patch soon. For now I'll just keep stock wheels on high perfomance cars.
 
Actually the effect is actual not just graphical. As an example, I was 3 seconds slower around Deep Forest in a stock F40 with custom rims. Myself and @Stotty tested several cars and each had the same result.

Believe me, I would not make a thread about it if I wasn't 100% sure... I don't make threads.
The question I have is why in the hell would you change the beautiful standard wheels on an F40 in the first place?
 
I know over the past few years a few of the Lemans LMP's have run wider front tyres then rears, could this be used to give such cars wider rear tyres?

Not to be pedantic, but they've 'only' run the same width fronts as rears, not wider. The loophole in the regulations on tyre size was found by Acura I think, and then Audi and Peugeot got in on it and it became a must-have. The new regs have changed it as well as the width of the car overall.
 
After reading about this yesterday I started thinking about my Aventador that I bought for the GT-Allstars-something-event, which would spin in pretty much every turn on High Speed Ring with Racing Hards. So I went back to stock rims and decided to try it out in with the stock Sport Hards, then tried Sport Hards on custom rims. It was quite clear that it was more stable on stock rims, as the front and rear wouldn't try to swap places all the time.

However, I have driven a lot of races using my 15th AE Huayra using custom rims, and haven't really had any problems. I actually golded the entire GT All-starts event with that one, that too was on Racing Hards. But it works fine on Sport Hards as well, even with custom rims.
 
For those people who don't understand a staggered setup vs non staggered and why its crucial to certain cars - your not car fans, go home. This IS an issue, do not pretend it isn't.
You must be joking.
 
I'm curious if this glitch affects the 15th Anniversary cars as well, as my Cizeta V16T 15th Anniversary seems to drive a lot like how others have described theirs while using custom rims...

Most 15th AE cars CAN'T have custom rims. I think only the huayra and viper can have them and they are both affected as normal cars.
Seeing that that Cizeta can't have aftermarket rims how can your Cizeta have this problem?
 
When you're previewing the wheels in the custom parts section with the stock wheels fitted, the widths of all wheels are correct. When you're previewing them with custom wheels fitted, they're all incorrect, including the stock ones.

Clearly, this is an error with the car data as saved in the garage. That might mean hybriding could expose those values somehow, although it seems that should also have been true of GT5.


Anyway, what's comforting is the relatively small selection of wheels compared to previous games (except GT5) and the fact that wheels scale perfectly well with any car, diameter and overall width, with no discernible change to the "dish" built in to the wheels, implying the offset is variable (in that the rim width is scaled from its outer edge, rather than its centre, keeping the hub the same distance from that outer edge, but effectively moving it relative to the centreline...).

What I'm trying to say is that the current wheel system smells like placeholder to me, and that they may be working on a more flexible wheel sizing system (including a more robust / intuitive way of varying the offset in the wheel meshes), since it seems the physics are capable of representing the changes to some extent. The "bug" as it presents itself might be viewed as a kind of "default value" for the wheels in such a variable system.

Can you say "patch after release"?

What I meant to ask is, because the 15th AE cars have different rims than their regular variants, does this glitch regarding custom wheels affect them? Or, to put it another way: Did PD only correctly model one set of rims/tires and that since the AE cars don't have those "Correct" rims, they're handicapped from the start?

I think they're stock rims but just painted black, aren't they?
I glanced at the cizeta and they look quite meaty.
