Well, the tires on the Top Fuelers expand like that because they are just sooo soft and spinning them that fast just causes them to expand. Nothing the teams can do about it. They need a soft tire to be able to put 7000hp down. So, they deal with the deformation it will have. But, I do get your point. ;) 👍

I haven't played it, but I am still upset that I cannot seem to get gold with the A-License Test in GT3 with the Camaro at Seattle. I just hope in the future that lap times for license tests are more realistic and feasible. I don't want things to be like "Le Mans 24 Hours" time trials. Those time trials are suicide. You'll be there forever trying to beat the best time.
 
Well... It seems a lot of people here can gold the licenses, so the bar isn't set too high, and there's no requirement to do so, it's just something for your own satisfaction, so I think the times should stay the same within reason. It remains a challenge worthy of completing this way. We don't want to make things too easy.

Are you remembering to use the rumble strip? Are you remembering to countersteer during the end of the turn? Are you remembering not to accelerate to hard during the turn? I can usually get gold within 5 or 6 tries.

Don't forget, with taller (larger diameter), wider tires, means taller, wider rims. All of this adds rotational mass. The more rotational mass, the harder the handling, braking and accelerating. There is a fine line between large wheel and tire diameter, and better performance handling. Racing tires are very tall. Meaning, from the the center tire rim, to the top of the thread, there is a tall area. You can't use a lower profile racing tire, if you decide to use a larger diameter rim.

The same goes true with brake rotors. People think, the larger, the better. Not true. Brake rotors add a lot of rotational mass, which effects perfromance. So, where is the line drawn between increased braking performance that larger brake rotors provide, and the negative effect of the added rotational mass that they cause? Same goes true with wheel size and width.

The answer is testing. Finding and figuring out the best size combination for a certain car. I hope GT4 will have something like to figure out. Yes, Kaz said there will be larger size wheels and rims in GT4, and the different rotational mass will effect vehicle performance, either negatively, or possitively.
 
There's another important aspect of performance where the weight of the wheel, brakes etc will be a factor. All of these will change the unsprung mass. This won't affect the racing cars so much, as thin carcass tyres, alloy wheels, calipers, dampers and carbon-carbon discs have reduced the unsprung mass down on the majority of racing cars to between 18 and 25kg, but changes might be quite noticable on the standard road cars.
