I wonder if anyone can point to a video or share experience as to what happens when oversize tires sticking outside the fenders side swipe a guard rail, concrete divider or another car(i.e. as in a movie scene when two cars are side swiping each other)?

I was at the Montreal Formula 1 race in 2007 when Kubica front tire frontally touched the rear tire of the car in front of him(thread touching thread). Needless to say the momentum of the two sticky tires rotating in the same direction amplified the force and catapulted his car to become completely airborn and made for one of the craziest crashes. This video does not show the cause of the accident, only the second part of it:

I wonder the same thing. Usually I'm stubborn when somebody veers into my lane because my jeep won't be damaged, but I do wonder if it would have more ill of an effect than just my tire marks being on their body.

Edit: I tried searching for a video and couldn't really find anything.

 

It's happened to me twice, both times at relatively low speed.

Full size dodge ram while pulling my ski boat, in the right-hand of two left turn lanes. Light turns green, I pull ahead and start into the left turn, chick in the mini-van to my left (in the left of the two left turn lanes) decides to go straight. A few smudges on my tires, ripped the hell out of the side of her van.

4door JK on an icy mountain road, hardpacked dirt. Long right hand turn, banked toward my side so oncoming traffic was higher than me. Oncoming full size f350 pulling a trailer came around the corner too fast, panicked and slammed on the brakes. Truck and trailer slid down into me and along my tires. Ripped both driver side flares off, and since I had tried to move further to the right to avoid, my right side was up on a berm, tilting the top of the driver side out far enough to get some scrapes along the glass and upper edge of the hardtop. But the tires kept me from having a bunch of body damage all down the side.

 

The van was low speed, the F350 was oncoming traffic, so the side swipe forces cancel each other. I would imagine you did not feel like the jeep wanted to catapult.

Picture going highway speeds and someone coming into your lane or veering into the concrete barrier. I saw once a full cab truck(18 wheeler without trailer) go over the concrete divider into the opposite side of highway once his front tire hit the concrete barrier at an angle and at more than 50 mph.

 

Just relating my experience based on the title of the thread "Side swipe with oversize tires", not my experience driving on the grand prix track in Iron Man 2...

 

I think the F350 scenario was just to share how his tires also protected his jeeps body.

 

Indeed. The usual fender bender results in no damage to the Jeep.

 

An idiot ricer sedan was zig-zagging through traffic , swapping lanes at ~30mph and drilled my JK's front side.

Zero damage to the JK ! The **** knew he was at fault so we parted amicably, except for the 35" donut marks down his fender

 

I think the facts you are missing here are that our jeeps don't travel at 180-200 mph or weigh less than 1500 pounds.
