Grind the R-Tires???

[GordonS]

As a result of search function, few months ago, I realized the potential of N-tires in testing "normalish" cars. So it was quite a shock when I now bought this BMW 2003 320 Touring car, which was fitted with racing super hards. It was like using a train! I had this habit using superhards in the beginning but not anymore.
OK. There is of course this natural grip level increase with winged race cars compared to road cars, but please, not that much!!??
There are, in this forum, many interesting debates about different tyre choises but mostly for road cars. What about these touring cars? Should I use sport tires to simulate RL gripping? Actually, I have always hated those S-tires but when I fitted those in the above mentioned racer I was able to make some serious tailswinging.
(I´m talking about testing, without that lame AI)

WTCC cars (like the BMW you have) do use slicks in the dry, so R1 may not be that far off. I've never raced on slicks IRL though so who am I to know.... The S tires could possibly resemble intermediate tires in WTCC.

I'd say go R1 (or possibly S3) if you wanna use tires that sort of resemble the what that car would use on a track IRL, if that's what you're after.

I also have no idea what the RL grip level would be. But I´ve played GTR which is said to be the most realistic racing sim, and compared to that, GT4´s tire grip loss is quite predictable.
Anyway, thank you Ske. S3/R1, so be it.

Folks, other opinions, please..

hard to say definitively - but i would guess that the handling is pretty accurate. If you watch the actual races in real life, you very rarely see anyone get out of shape at all, unless they've had some 'help'. Most mainstream racing formulas allow for very high grip, but limit power primarily.

Also, i can understand saying somehting handles like they're on rails, but surely nothing (except maybe the tank car) handles like a train. Last time i took my 4-6-4 down to midfield, i really struggled with the handling. tho after some serious tweaking and new tires, the bad boy really hauls.

You've never watched a full modifieds race before huh??? hehe...

My IRL RX2 Capella is currently racing in a full modifieds class... It currently has aroun 300kw on the wheels with huge 245 Slicks on the back... And I get out of shape with too much power coming out of corners.. hehe..

Here's a news flash too... Touring cars use slicks mostly... Any classes that don't use slicks, use "trick" tyres... here's what I mean...

Before my car was modified, I raced it in the street legal class... and that demanded STD road tyres... I race on 205/14's... One of my friends race in the Stannic Group N class in a nissan sentra... they used 175/14's... he gave me an old set, yes and OLD set to use and I took my lap times down by 2-3 seconds on various tracks...

Oh i have, don't you worry! The more modified the better. They are gold!!! I was referring to the "mainstream" meaning the bigger racing series eg touring cars etc.

Not sure what class it is officially called over here - but there is a class of pretty much every body type where the sillouette has to stay pretty much the same with wing allowances, engines etc is pretty much a free for all. they tend to whack in 7.0L chevs into pretty much anything and everything. I recall a great looking Saab and Alfa both looking real sweet and real quick as well. Different side of the coin there. Power >>> traction!
