What is economy tyre? What is the difference between economy tyre and sport tyre?
 
Engineering news on Phys.org


Economy tyres are either really cheap tyres (if you're not too fussed about performance or safety) or tyres which are designed to give minimal rolling resistance and increase fuel economy.

Sport tyres are designed to offer more in the way of grip and traction.
 
Car Performance

Hi!

Which variable a) type of tyre (soft tyre, hard tyre), b) weight of the car, will affect the car performance more in terms of speed? Explain.

Thank You! :D
 


What do you mean by speed? Pure top speed? Broadly weight and tyres don't affect top speed. Thats power and aero.

If you mean lap time. Probably weight is the primary killer of lap time, but tyres are equal or a very very close second.
 


Why does weight is the primary killer of lap time?
 


acceleration for straights.
more force making the car not want to turn corners.
 


Reducing weight will improve the performance and economy of the car. Soft tires will assist in turns and acceleration but fuel economy will suffer. Hard tires last longer and roll easier but you will lose acceleration and cornering.
 
Road Tire

What is road tire? How does it affect the car performance in terms of lap time?

It's a tire for the road.

It can affect it up or down.


Why are you asking essentially the same question in many threads? It's also far too vaired to just ask how does it affect lap time.
 


Road Tire is when you get very weary of driving and your eyes start to glaze over because of too much windshield time. It effects lap times because you get bored driving and attention span wanders. Especially bad if you have AADD...cure is to have many blonde hair blue eyed pit members with large chest and small pit sign you can view every lap...

I've merged 3 threads by GuMing with essentially the same questions.

GuMing -- please confine your questions to this one thread for now. Please also give us your thoughts on the questions. Is this for school?
