Hey guys I have 33" Revo's and have had them for over a year. Love them. Recently I bought new wheels and had nitrogen put in them. Now I have Wheel "howl" from hell. You know the faster you go the higher the pitch slower I go you hear it literally winding down to a stop. Is this because of nitrogen? Or should I look for another cause. It only started when I got new wheels and its driving me NUTS.

 

Check your wheel bearings. The same thing happened to me on my '83 F150. Had new Bridgestone A/T's installed and all of a sudden I had terrible "tire" noise. A buddy rode with me and immediately recognized that it was bearing noise. Just a coinkidink I guess. Checked my cone bearings and they were shot. Changed them out and no problems.

 

I dont think its that I just had the drivers one replaced 8 months ago I suppose it could be the passenger but thats a 300.00 guess if Im wrong. However when the first one went out I felt this aweful vibration and grinding through the steering wheel. thats not the case here so far.

 

Some questions.
What is the load range for the tires?
What pressure are you using in them?
What was the width of the old wheels and what is the width of the new?

 

It may be the tires. Were thay rotated when the new wheels were installed? If they were, they may have been cupped slightly and now they are making more noise because they are rotating in a different direction. I've heard cupped out AT's that were as loud as Super Swampers.

 

Good Q's from Kingfish, also, if the tires were rotated when you got the wheels they may have had previous wear that was not audible before. Feel the tires tread with the flat of your hand, if the tread has no ridges, bumps or unevenness I am wrong. If the front tires are feathered or lumpy in any way they might be your sound.
Bearing noise is the same pitch at any speed, it gets louder but not higher as you accelerate.

Also, along the line of Kingfish's thought, check the offset of the new wheels, if it does not match the OE offset(not backspace) you could get sound because of steering geometry changes with offset changes.

If the sound turns out to be from tire uneven wear get the truck aligned right away, it can save your tires, plus it makes handling best.

 

Well I have had aftermarket rims for a long time and the new ones are the same size etc. cause I didnt change the tires just what I put in them. I havent had an alignment since I did my suspension lift, I guess i could try that. The tires did get rotated but its not the first time they have been, I have just never had this kind of noise.

So is my only option an alignment?

Thanks for everyone help by the way

 

Please answer the other questions I asked. Load range and tire pressure.
You did not state whether you had unusual tire wear, a sign of out of alignment.
