A couple of guys have told me that ... but the thing is that i replaced the rims and tires almost 8 months ago. And all this started about 2 months back. So if the problem was the rims or tires .... should the warning lights have come on after i installed them ?

You think it can be some sensors ?
Because the warning lights come on ... one after the other ... as soon as i start driving it. Like within 5 seconds !!!

Thanks for all your help guys.
