Annoying Tire Hum at 55 to 65 MPH

You may try inflating them to the maximum load tire pressure and see if that makes a difference.

That would be my first change. Add 10 PSI and see what happens. Doesn't cost anything. Also try rotating them front to back first then left to right before spending money. Check the tires first to ensure they are all position type and not steer or drive only. A left to right rotation will change the direction of travel so check to see if the tires are unidirectional rotation also.

Some tires are designed to run quieter and some aren't. Unfortunately the dealer probably bought the cheapest tires he could find and they are noisy. I know of nothing you can do other than change the tires. You may try inflating them to the maximum load tire pressure and see if that makes a difference.

Get rid of those china bombs. People trying to save a buck on the single most important thing on your RV.

There is way too much knowledge needed to 'tune' a tire for running at speed.

I knew a old guy in Florida who had used tires shipped to him by the trailer load from up north. He "re-grooved" them and sold them to the truckers who were hauling fruit and produce out of the groves to the warehouses. He did quite well with those "re-grooved" junk tires. Those guys didn't let much dust settle by going slow. But on that junk, they didn't worry about blowout damage either. I never had much luck with either re-grooved or recapped tires, let alone any used tire.

His "re-grooving" tool was basically a heated double bladed knife with a bridge that attached both blades. He claimed it was "branded" and "registered" so he could tell if a tire was re-grooved with his tool.

In my days of selling tires, I had numerous customers complain about different tire noises. Some tires did not belong on certain vehicles, no rhyme no reason. More the luck of the draw than anything else. Good luck.

Just wondering if other Samson tire owners are having the same problem.

You should have put that in the title.

This is the tire that is humming, is the tread pattern the problem.

They did not hum at 1st but after 2000 miles the humming started and its getting worse, did have the front bearings checked and they were good.

They are Samson tires, 245/70R/19.5.

Try a tire rotation.

I have no idea!

The only grooving I have done is to large lugged off road tires, tractor tires and large mud tires.
None of which was to reduce noise.......it was all about bite/grip at low speeds.

They have wear bars that slap the pavement if you have them grooved where the wear bars are it will stop.

Just did a quick search on the internet and many said siping did not change the noise.

Grooving & siping are too different procedures.

So cutting in more groves will help, I saw a can get a tire groover on amazon for $65, do I cut groves as shown in pic than.
