The most useful of the two radii is curb-to-curb since that is what most people will encounter in normal driving (as most front bumpers can just fly over curbs this isnt the case for something like a Lamborghini, of course), so thats what well focus on here. Quite simply, a car with a tight steering radius will require fewer rotations of the wheel, making parking and maneuvering in close quarters much easier. Lesser the turning radius, more convenient is the car to drive in tight localities. Still, this trade-off has been deemed by many OEMs to be acceptable since it improves turn radius under the normal conditions most customers will encounter and Toyota is certainly not alone in using this method.

How the car hits the small overlap barrier depends on the overall width of the car so if you push the wheels further out you just increase the width of the car and the way the car hits the barrier moves with it. A shorter turning radius generally translates to a more pleasant driving experience (unless you're used to planning for three-point turns instead of U-turns).

How to Remove Decals from a Car - Easy Techniques to Try. Huibert added a simplified version of my derivation above, leaving out the geometry bits proving that the turn angle is the same as the bottom left angle in that triangle, so if you want a simplified explanation of how he got his equation, here it is: Our turning radius calculation also ignores deformation/slip in the tires during the turn, but it should be fine as an estimation. I had never considered the tire envelope encroaching on space. Here, Ill have Huibert talk about it: I think one of the commenters [on the Focus-focused internet forum] hit the nail on the head which is that the wider 235 tires keep the suspension from being able to turn as far without the tire hitting the body rail.

This type will need far more turning space than the ones mentioned above, but we will focus primarily on the WB40s and 50s. Now, while 50 degrees is a lot more than the 30 degrees we are using in our example, dont forget that this angle also has to account for suspension travel. Therefore, when you make this turn you need to ensure the back trailer does not swing out so far that you hit the cars on the opposite side. If you wanted to get a smaller turn radius by getting more turn angle out of the front wheels, the only way to achieve that is to make the track width and the rest of the car wider or by making the tires significantly smaller.
