M/T Tires - worn down vibration level is nearly giving me an orgasm

is it just me? ive put probably a good 40K miles on my hankook mud terrain tires. ive noticed now, at a slow down at around 15mph, the vibration is so severe, it sounds like my entire front end is going to rattle off (it has caused people to turn their heads - yes, it is that audible)....

i can feel it in my gooch through the seat... i dont know if this is necessarily becoming a problem or i actually enjoy it at this point.

anyone else experiencing this? maybe its time to replace the tires.... or invite the lady to drive the tacoma more frequently....

 

my hankook dynapros atm rf-10s started getting nasty loud around 35k..... I wont be going back.

 

isnt this just the life with aggressive tires? i remember way back when, BFG's cupped horribly as well near the end of their life. they look great... but man, even rotating the suckers every oil change they still wear fucked up.

 

Pretty much... Im actually kind of regretting my Cooper AT3's in an LT265/75R16 in a load range C.... took a 1mpg hit because of the extra weight

 

My toyo at2s started cupping on the edges. Might be due to low pressure.. the cupping was causing steering wheel wobble

 

interesting. never thought about the tire pressure. wonder if jacking that up a bit would smooth it out...

 

Ive got about 35k on them and only put air in twice. Probably need to check more often like monthly. Idk what pressure to keep used to do 35. Did 37 last week

 

My summer tires are nearly bald. They hum so loud at certain speeds, you can barely hold a conversation in my truck. It's even louder than my tinnitus.

 

I still have the Rugged Fails that were on the truck when I bought it new. 49,000 miles on them. Rotated them every 5,000 miles and kept the air pressure checked. I can't say they've been great tires, but what the hell, I'll get another couple of thousand miles out of them. Won't be buying another set of them though. I just don't know what to replace them with. I do most of my driving on the highway, but when I need to go off road, I really need to go off road, and really need my tires to perform. Don't know of any tires that are really good on the highway and off road.

 

What brand is it ?

I want an orgasm

 

I have about 30k on my MTRs and they're dust but still super quiet. I leave them at about 28-30 psi.

 

No....No it's not (as a broad general statement) May apply to certain brands, different driving styles, etc...but not ALL aggressive tires are a liability.

They have to be kept rotated and balanced. Truck must be properly aligned. Same rules apply to ANY tire if you want maximum life and minimum of problems. Arguably, problems may be compounded with mud tires and bad maintenance.....

And some brands are better than others, even with a brand that has a good rep...you'll get negative results in some instances.

They will wear quicker than a less aggressive tread, but I've seen plenty of mud tires wear well and evenly, ride great throughout their life span.

For comparison sake, take into account I run what would be considered (in comparison to most A/T tires) as an EXTREMELY aggressive tire. With ZERO complaints.

I'm currently closing in on 32K on a set of Cooper Discoverer, STT PRO's (285/75r16 load range E) They ride as good now as any tire I've ever had. Noise level hasn't increased, even gas mileage is better than most people report on Tacoma's with smaller, less aggressive tires. They were balanced at install, but not since. I rotate every 5000 miles. Every 3rd rotation, I swap them from side to side. (Not generally done on radial tires, but I see better wear characteristics by doing so) I won't know until I get them to a higher mileage, but measured wear vs actual miles indicate that I can expect AT LEAST another 20K, maybe more. For a mud tire, that's a ton of road miles.

I had Goodyear Duratracs prior to the Coopers. They wore extremely well....Still at 80% tread at 45,000 miles when I went to bigger tires. They were hypersensitive to pressure on ride quality and noise level though.

With the price you pay for QUALITY MT tires, this isn't a major imposition if it dramatically extends the life and "manners" IMHO.

 

i went the cheap route and picked up the Milestar Patagonia 255/70/17, and they have KILLED me with the cupping! by the time they are flattened out from rolling on the rear the fronts are killed again. its been so bad for me, ive been wondering if i needed to replace some kind of suspension part to go along with the lift to make everything ok... but the alignment shop hasnt mentioned anything being bad or not coming into spec. next time it will be more of an AT inspired tire... maybe BFG AT Ko2's like i have on the other truck.

on, and im getting around 15 mpgs with these.

 

This ^^
A lot of people don't understand tread wear on mud terrain tires or tires with large gaps between tread blocks (this wear still occurs on all terrains, all sessions, etc, but isn't as noticeable due to smaller tread gap and harder rubber compounds). Those larger gaps and softer compounds allow more flex/deformation in the tread blocks when accelerating and braking. Not as much as in this picture but it still happens during acceleration and braking.

People tend to accelerate more than brake, due to how our roads and traffic controls are engineered, causing this uneven wear or "cupping".


Having the proper tire pressure will help with wear and grip/control/contact patch.

As Discount/American tire states:
"There are many different tire rotation patterns. Both tire and vehicle type will determine which pattern is best to follow. As long as the tires are not directional, they can be rotated from side to side. If the tires are directional they can be rotated side to side, but they will need to be dismounted and reinstalled facing the opposite direction. When rotating your tires, you should ensure that the air pressure has been set to the vehicle specifications for all of the tires. Many vehicles have different air pressure requirements for the front and rear tires. If the tires on your vehicle are not the original equipment, they may require a different air pressure than that which is specified on the door placard."

As for our trucks, I believe a rearward cross pattern would work best, but any cross pattern will help with wear.
