Measured tire noise??

[wanderer]

I havent seen anything anywhere where the road noise made by a tire is actually recorded in decibels . It would be really useful to see how competing tires compared at 5k 10k 15 k 20 30 and 40 or 50 miles . Of course comparing a five or six cents of tires over the life of a 50,000 miles would be pretty much an opus but it would be useful.

I compared my aged 35” KO2 to a new set of 37” Mickey Thompson MTs on the same stretch of road leaving Discount Tire. The frequency was lower on the MTs but it changed a lot as the road surface changed smooth vs rough. At about 60mph the primary source of noise became the wind on the windshield.

I would love to see good data comparisons between tires also but I think it would need to be done on a single rig, on the same road (or better, an indoor test facility), with testing equipment that can isolate tire noise.

With the same wind speed in the same direction, ideally with the same temperatures. Good luck with that unless you're in an indoor test facility.

I have had so many different tires over the years as an admitted tire whore...I am currently switching back and forth between two sets of Mickey thompons one set of AT's and the other MT's. I have about 9000 on the AT's and 7000 on the MT's the MT's are starting to get louder than the AT's but for the first 5000 miles were actually a bit quieter....I rotate about ever 2000-3000 miles could be earlier if I was swapping them and they had say 1800 miles I would just go ahead and mark them for rotation when I put them back on. I used to really love Cooper ST maxx's and had several pair but when they reached about 10,000 miles they would get really loud and after rotations they would scream for a while until they had a few hundred miles on them...believe it or not one the worst for noise was a set of Toyo AT3 in 35x11.5-17 I got rid of those pretty fast because they were so loud. they guy I sold them to was happy with them so not sure why they were so loud on mine.
