If you mean tires that come stock on a car, those line up with Comfort tires. If you mean the ones on your race car, it'll be Sport or Racing, depending on your car. Hope it helped 👍.

Not so much to be honest lol.
I mean, if I want to race with tires that comes with the real car. Real cars use what tires? Sports hard? Medium?

Some real cars use a Comfort Hard type tire.
Some real cars use a Comfort Medium type tire.
Some real cars use a Comfort Soft type tire.
Some real cars use a Sport Hard type tire.
Some real cars use a Sport Medium type tire.
Some real cars use a Sport Soft type tire.

And, some real cars use Racing tires too.

What real car are you attempting to use?
 
As far as hard/med/soft, there's too much testing to be done there for me to be certain, but if you walked into a real new car dealership and purchased a new Buick, it would have Comfort tires on it. Purchase a brand new Camaro SS, and it would have Sport tires. Take your new Camaro to a closed circuit race track, and you would instal Race tires. Make sense?

Hello all.
What tires in game simulate best to real life tires?

I think sport tires are pretty realistic. Comfort tires feel way off with not nearly enough grip and racing tires have way too much grip but it does all depend on the type of car you're using as well. 👍
 
Calan_SVC, a GTP member did a thorough research on GT5 tires and how it relates to real world performance. If you ever played GT5 Prologue, you might'e noticed in the game's menu there was a list of "Recommended tires for Real World Performance". Obviousy there isn't one in GT5 but you can find Calan_SVC's prepared list here (warning: it's a google spreadsheet): http://tiny.cc/hwog1

Also you can use a calculator provided you know the real world skid pad data (in "g") of the car(s) but here's Calan_SVC posting on the subject:

I dont care about gt5 stock tires. I need real life

It says in the description of the tire that they come stock on cars. "GT5 stock" is no different than real life stock...
 
Regardless of the skid pad G rating (which in RL can vary from tire to tire, depending on the tire manufacturer, how grippy is the road, how wide is the skidpad turn radius, etc - it's pretty much a pointless information unless it always comes from the same source with very clear test conditions), I go in this way:

  • Comfort hard -> Cheap, energy saving, low rolling resistance tires that can be found on econoboxes or many city hybrids/electric cars
  • Comfort medium -> all-around general purpose quality touring tires that can be found on most passenger cars
  • Comfort soft -> sports driving oriented tires suitable for most driving situations (although they might be not so great on wet conditions)
  • Sports hard -> entry level semi-slick tires for track-day usage. NOT suitable for all-around driving on public roads, although road legal.

Most road legal cars should have comfort tires.
I find that in GT5 the "stock" tire choice, especially on standard cars, is often one class higher than what it would be in real life.

It's true however that a problem in GT5 is that tire specifications are hard-coded in car specifications.
When for example you buy "sports hard tires", their performance vary depending on the car.

In GT5 I've found Comfort Softs to be quite effective on a wet track, although I know what you mean in RL. I haven't really tested the others, now I rather want to. But on a track that is undriveable with Sports Hards, the CSs make it quite manageable.
 
Yes, I noticed too that in GT5 comfort soft tires have a noticeable advantage over sports hard ones on wet surface (I haven't tested other comfort ones in detail to tell the truth). In RL it would be different as most sport street tires don't have very deep treads for water evacuation, but they would be still much better than semi-slicks in those situations.

I guess that more tire types in GT5 are needed (for example, snow and dirt tires in GT5 are more like specific rally-oriented race tires than road legal street tires for snow or dirt surfaces). But first, the whole tire system would need to be revamped. It's too much simplistic currently. PD need to separate tire specifications from car specifications (as I wrote, tire size data is hard-coded in car specification data, for example. Cars which appear to have skinny tires DO have them).

Then, we would be able to select different tires with differing specifications (type, width/size, load - meaning rigidity - etc) depending on the car, but I fear some people would end up complaining of the added complexity.

I don't think that's true. What if you receive a car that is on comfort hard tires?

There aren't cars that come with comfort hard tires as stock in GT5 - none that I've noticed at least, and I think I've checked out many kei and small city cars.

I just can't seem to wrap my head around how you conclude that comfort tires are sporty but it's more than likely just me.
 
Comfort Softs are like an average Summer Only tire. I think Sport Softs tires in the game feel more like DOT R-compound tires. Racing tires are something completely different.

Because the comfort tires in the game generate as much grip as a real life high performance street tire. The game tires outperform their real life counterparts on every level.

It's just that the definitions used in GT5 are misleading. As depicted in the background pictures in the parts screen and as their wet performance suggests, they should be read like this:

Comfort tires -> treaded summer road tires [Example]
Sports tires -> semi-slick tires [Example]
Racing tires -> slick tires

And in GT5, each category has 3 "grip levels", with "hard" being the worst and "soft" the best, obviously.
So I assume, for example, that a soft comfort tire is a high performance summer tire, while a hard comfort one is an energy-saving model.
 
Would I be right in saying that a true to life tyre for the F2007 would be sport soft? Since they had grooved tyres back then to limit their grip, which is why the F2007 is easier to drive then the F10 on race hards.

Where do you get this "valid" information, I have to disagree with that one.

There was a rather extensive test done by a member here on GT4 tires several years ago comparing real lap times against game times. The most realistic lap times came on normal tires (now comfort tires). Sport tires were consistently several seconds faster than reality. I don't have the time to dig though old threads, however. Help yourself.
 
I really don't think an m3 will use comfort in real life. Too dangerous. I am guessing the really slow tiny cars use comfort, as "normal" use sports

Nope, the F2007 racing tyres have grooves.
 
The tires in game look a like no matter what compound it is. I'll test out both cars sometime and compare laptimes with each other and real life to see what's accurate.
 
Regarding skidpad test, the best source and probably the most comprehensive is Road & Track. And because it's from one source, it's pretty standardized and here's the explanation from Road & Track on how the test is conducted:

Skidpad

The skidpad test is the other dynamic exercise we measure using the VBOXIII. To test steady-state road-holding ability, we measure a car's average lateral acceleration (reported in g's) around the circumference of a 200-ft.-diameter circle in both directions. Not only does the skidpad give us a tangible value to supplement our subjective impressions of a car's understeer characteristics, but it is also a good indicator of how well it's been cross-weighted (the closer the g's are in each direction, the better the balance).
Most often we enter this exercise at a moderate speed in 2nd gear (in rare cases a gear lower or higher) and trail-brake to help initial turn-in. From that point, we strive to maintain a mild understeer condition at a speed that will allow us to push no wider than our delineated circle. We do two to three complete revolutions before switching directions, and then repeat the entire process once more. We limit revolutions to a maximum of three at a time in each direction to avoid overheating the front outside tire and possible oil starvation, a concern in wet-sump cars.

Of course, I would use Calan_SVC finding as ballpark figures which definitely beat guessing. But if for most part the choice of tires seem spot on although personally I would go a compound harder for Arcade TT (if the suggestion is Sport Medium, I'd choose Sport Hard) simply because the mode does not simulate wear.
