    So I got my Gen2 Raptor about a month ago and overall it's been great. However, since day 1 the truck feels bouncy in the rear. It is noticable at all speeds but very prominent around the 35mph range. I thought it was a break-in issue but I put 1000 miles on it and the bounce is still there. Feels like the tire has a soft spot in the rear. I took it in to Ford and they inspected all the tires and checked the balance ( all tires were good). The problem still exists. I thought the tires would be smoother or is this the way it is? Anyone experience an issue like this?

    Have you ever driven a truck before? Not being a dick. The first time I bought a truck after driving cars my whole life I thought the same thing. However, I haven't heard of any bed bounce issues with the Gen 2. Maybe somebody else has some better insight.

    knock the pressure back to approx 38 psi and see if that helps. Jack it back up after you get used to it. It's a truck, it might ride like a caddy, but it's still a truck...

    Um, ya..... Ever own a truck before? There's not much weight back there so it's not planted like other vehicles. Now add to the fact your driving a Raptor!!!! It has 14" of travel back there, it's not supposed to ride firm!!!!!!

    Throw 2 50# bags of salt in the back and see what that does.

    OK GUYS - this is a good one.. Just came back from Ford Dealer 5000 miles on the clock. Got my oil changed (free of charge from my dealer - synthetic blend recommended from Ford) anywho... asked if they would rotate the tires please.. "well Mr. customer we recommend you wait till 10,000 to do that..." "our mechanics feel that the tires are just starting to break in at 5,000 and dont need to be initially rotated until 10k then every 5k after that.." blah blah..... any thoughts Gents?

    I call bullshit. I rotate my tires every 5k. Period. I got 65k out of my last set of duratracks

    ya from dealer they had the KO2s cold pressure at 44lb so after heat up they went to like 48 and at high speed i was bouncy balls. Lowered these to 38 cold and now its spring time they warm up to 41-42 which is a big difference at high speed. this is with no load or equipment in rear btw. as texas summer we get up over 100 easy and humid

    Yeah - So i was poking around the BFG website and one of the reps popped into the online chat box so i asked him. They recommend 6 to 8k depending on what kinda of driving / conditions / towing you are doing.. I called the rep back that i dealt with at the dealer and told him. He put me hold for a sec then came back and said he noted it in the file and I should stop by anytime b/t 6 and 8k miles and they would be happy to rotate my tires at no charge..

    Just my 2 cents... I've driven 7 different Ford trucks and they're all light in the back. In winter, I used to throw bags of salt or sand into the beds to add some weight and also have help if traction was needed. On my last truck, I bought a Shur Trax water bladder. You fill with water to add weight, then just drain in Spring. It never did freeze because the truck was kept inside, although it is designed to freeze. It was cleaner to work with than bags of salt/sand and easy to store. If anyone considers this product, I'd say go with the midsize model for the Raptor and be sure to secure in the bed. It will slide on hard braking and it will affect your stopping distance.

    As far as the Raptor, mine bounces especially when hitting pot holes while rounding corners. It feels like the bed is taking off on its on. I'm running 38 in my tires.

    A little off the subject, Weather Tech now has mud flaps for the Raptor. I'm still waiting to see Husky's - possibly mid June.

    You might want to try heavier leaf springs if the bounce bothers you. There are many available in the aftermarket arena.

    Drove a '13 SCrew 4x4 until I recently purchased my '19 Raptor.

    Had KO'2 on the '13 with about 30,000 miles and they were wearing perfectly. Ran 45 psi front and 32 psi rear cold. Rotated every 5000 to 6000 miles. Currently running the same pressure in my Raptor. Ride is really good and no bounce other than normal truck handling. The '13 was definitely bouncy in the rear if I ran over about 35 psi and wasn't hauling a load. What I normally do is air my tires up a little higher than I know I'll need, put a couple of chalk lines across the tread and drive a straight line. I then air them down slowly until all but about 1/2 to 3/4" of chalk remains on the outside of the tires. Have done this for years on all types of vehicles and have always gotten at least the tire's rated mileage with no issues.

    45 seems high in the front but if it works for you, more power.
