03 Quadrasteer 3/4 suburban - had new tires installed and since then truck is all over road. Used to pull camper perfectly, now can't stop camper from wandering. Steering linkage appears to have very minor wear - 65,000 miles. Could tire change caused an alignment issue between front & rear tires? Ever heard of this before? HELP!!!!

Are you running the same profile tires? Hows the weight rating for them? How's the inflation? The new tires might be allowing the truck to float too much. I've seen this a few times from people putting on the pretty tires instead of the work tires. They ride fine without a load on them, but once they get the wieght on them, the sidewall flattens out too much.

That's just the first ting that comes to mind.

I aggree with Scotty-B and I'd also add this. It could be a by-product of any brand new tire. If you replaced very worn tires, you may actually be feeling the tread flexing of the new tires and are not used to it anymore. Especially if you replaced with nice deep tread A/T style. Miles would cure that.

Thanks for the input. I did originally replace them(Firestone AT) with Michelin LT, but when the swaying started I took those tires back and got Goodyear truck tires. They have the same load rating & sidewall E0 rating at the original ones and it's still swaying. I know that these 4 wheel steer trucks have a very sensitive alignment from front to back, so know I'm wondering it it could be off some how. When you tow it feels like the back tires are not in sync with the front? HELP
