Thanks for basic formulas :), I am a little more advance.
"...it shows drawbar pull/1000 pounds to be....(depending on surface)
Asphalt....... 12 to 22 lbs.
The formula for air resistance is.....
F=FA x .0025 x MPH^2
F is additional drawbar pull needed to overcome air...
I can't find good formula to calculate power lose, Junior37c could you share.
I found some ideas here: http://www.physicsforums.com/archive/index.php/t-321017.html

Curious but Dunlop here don't know much about them, except price of course. I asked guy how they recognize compound and...

I will check it and post it.

Studying power is pointless. let say we have 200 hp instead of 560, wideness of the wheel will make huge difference.
OK guys, but at some point friction should be taken under consideration. 80% of racing is acceleration with to wide tires I will lose on acceleration.
OK, I can use 310 wheel at front and rear but I need to put wider rim for front wheels +6kg of rotating mass. I lose on acceleration...
Hi There,
I am building my car for time attack and I wonder how to calculate proper tire width.
Let's take stock toyota supra mkiv 320 bhp, 1560 kg, 51 to 49 weight distribution, front tires 235/45/17 rear 255/40/17, spring 7,5kg for front and 3,8kg for rear.
Now we striped car and we have...
