i have a 2008 f450 that came stock with continental 225 70 19.5 tires. they are are hsr's in front and hdr's in rear, load range G. i loved them. got 42,000 of all towing miles and started towing a trailer when truck have 300 miles on it. drove perfect, no sway, drove like it was on rails. now the problem.
just replaced them with same tires size, brand, and load range. they are absolutey all over the place. trucks tracks straight with no pull but when you move the steering wheel back and forth a couple times it feels like the truck wiggles and sways three or four more times. dealers are telling me that i am used to the bald tires and the originals prob did that when new. i can tell you they did not. i have tried 110 psi in all six and now i have 85 psi in all six and it is the same.
If im reading your post right the truck had 300 miles on it before you hooked up, How many miles are on your new tires? I would wait for 300 miles before worring.
i now have 900 towing miles on new tires. they are the same . all over the place. the oe tires drove perfect right off the lot. these new ones are even all over the place without the trailer. it is a terrible feeling. if you come across uneven highway or lanes you could sway right off the road.
is the tread deeper in replacement tires vs oe tires. even if they are same brand and tire.
60k - seriously ? I have 35K and have rotated the fronts from side-to-side, and also had to flip them on the rim themselves due to wear on the outer edge. Backs as expected are fine, but I'm heading toward 40k replacement as well. 90% highway, and I have had alignment checked. You definitely got the lucky one :woot:
Check the DOT numbers, in particular the date codes branded on the tires, they may be old stock, and if they were stored improperly for an extended period, it may take a while for them to settle down, or they may never settle down if they were bottom of the stack too long.
I had a set of Goodyears that were like this about 10 years ago, they wobbled and squirmed like crazy. Load D 16.5 33" Wranglers. Turned out 3 of the 4 tires were over 5 years old, the 4th was new. I demanded a matching current set and watched 4 fresh tires be mounted. Drove them 30k to wear them out after that, and the replacements were fine. Worth a look, trust me.
Hello,
I have the exact same truck as you and the EXACT same problem. I was researching it online and came upon your post. I registered here just to see if you found any solutions. I did not go back with continentals, but am still having that same sway feeling. It feels like I'm running 40lbs of pressure and the trucks rolling side to side on the sidewall. I can't stand it. If you catch a groove on the side of the road, it will damn near make you lose control. I've gone back and switched out the tires twice with stock size 225's. I'm now rolling on 245's and theres no difference. I don't know what to do.
I agree,check it out... worn out shocks can and will cause sway.
I actually did not like the way my tires grabbed the road when I bought my truck. After a while they tamed down and all but stopped, but I noticed immediately when I drove it home that it would grab grooves and steer around pretty heavily. It never swayed though just grabbed and steered from grooves and such....
rotorracer. any luck. nothing hear. same crap. thought i would wait them out. now at 5 k. they are the same. i have bilesteins (5100) on front and rear. same thing no difference what so ever. on highway today towing and one side was paved , other not. thought i was going to wreck the whole rig.
If you are not towing, soften up the rear tire pressure. You are experiencing Rut steer. The front tire tracks with the inside rear and the outside is carving into the rut because of how hard it is.
Have you replaced your steering stabilizer shock? I do not know if thats the problem but seems like you have done everything else.
