Recently, i had a discussion with someone about tire width. I claimed, that with bigger (wider) tires, a car would have more traction/grip. The person i was discussing this with, agreed with me, up to a certain point. He said, that if the tires were too wide for the car, the opposite would happen, less traction/grip. He also claimed that the chance of aquaplaning would be higher. My thoughts on that were that that mostly depends on the kind of profile of the tire. It seems to me that if the same tire, on another car (fit for that tire width) would provide good traction/grip without increased a

Well, both of you are correct. In general terms, a wider tire has a greater contact patch with the ground, so can provide traction. As your friend stated, though, the tread pattern/depth will have a lot to do with how the tire performs during inclement whether. Take for instance a race tire which is rated at a width of 325mm. With your line of logic, this tire would provide excellent traction for the vehicle. And this would be true, unless the tire was driven on the street where there is water. The car would not have the traction needed to sustain type of safe operation. Take the same 325mm tire and place it on snow. You can expect a loss of traction. In fact, a skinnier tire will work better in snow than a wide tire would. The reason for this (I believe ... no empirical evidence) is because it has more weight per square inch due to the smaller contact patch. It also cuts through to the ground better instead of riding on top of compacted snow. There are other factors involved here as w
