Ultimate Road Car

COVER SCREENSHOT:

Good evening man. I'm here to say you should add slick tyres to the mod since its like undrivable on those road "super(not really)" tires. Grip is none.

‘Mod Comments’ thread started with the most popular request.

First of all, in the competitive simulator realm, neither the official ‘Online PB's’ system nor ‘JaR’s hotlap system separates results based on road or race tyres usage; this will discourage players using genuine tyres from participating.

Now, LFS tyres imperfection is kinda opposite of ‘low grip’:

Quote from Scawen :

... tyres had too much grip and this was causing the inside wheels to lose too much load while cornering.

Combined with slicks' traction, inside front wheel is lifted off the track, which is ridiculous.

However, perceived lack of grip may not be caused by any flaws in the tyre model — watch her roll being ‘full send’: by Tiff Needell (from 07:10) and Naoki Hattori (from 15:40).
If the goal had been lap time, we might have said the suspension was too soft for its power; instead, comfort was a priority:

Quote from Driving Ambition page 125 :

Mansour Ojjeh's original suggestion of ‘the kind of car you could drive to the South of France in a day’

So, during acceleration rear wheels gain excessive camber (needed to compensate for significant roll) — the same kinematics that maintain contact patch during turns — weaken it on straight. There is anti-squat geometry to fix this, just currently not supported. And even if it were, torque would still be excessive: wheel spin when shifting into fourth gear (from 33:09).

The goal is not to make her the fastest or the most driver-friendly mod, just to reflect the inspiring idol.
