I ride in hilly and uneven terrain, so I am curious if tire pressure is critical to stability. I found I had close to 6 LBS in my tires, and took them down a bit. It seems softer, but more tippy on side hills. Anyone have some thoughts on how tire pressure affects stability.

Really depends on what tires you run to. My Growlers have stiff side walls and even with fast aggressive driving over rough terrain, I've settled at 4 psi all around. In comparison stock tires are much softer as you've observed.

I've found that 1 to 2 psi difference can drastically change an atv's ride quality and handling characteristics.

How often do you put air in the stock tires, since I ride often, I check it once a month and the OEM tire gauge is garbage. I always end up putting air in them. running 5 to 5.5 psi in the front and 4.5 to 5 psi in the rear.

That is good pressure, I have only needed air a few times in 4 years. I do run 15 pounds all the way around once I put chains on for traction in the snow. That keeps the chains snug and it seems to work well.

I hardly ever use a gauge but judge the pressure level with my foot on the tire. My foot is calibrated close to 5psi.

Other than that I also have a digital gauge that I'll use if I am around my home.

Tire psi is up to the rider. Some like more air and others like less.

my general rule of thumb, as long as the bead does not fall off lol, I like the oem specs for the pressures.

27inch tires 15lbs in the rear 13lbs in the front, strictly road use. It seems the more pressure the better they handle..

I ve been aggressivly beating the crap out of my Pitbull Growlers 26x9R12 square set up @ 3 psi all around for last 500 kms ( 300 miles)

So fare so good.

Low pressure of 4 to 4.5 is questionable on stock 2 plus. Dealer sent me home with 3.5 in the right front and the tire folded under on hard left hand turn and rolled on my chest and FX 3 ribs . On my limestone terrain/ ridge I have settled on 8 lbs all around on Kenda HTRs. Turns better, all the traction I need, superbside stability with the 6 ply rating. To each his own... low pressure gains me very little in loose creek gravel.

Hilly uneven terrain here as well, I set my tires to 5psi all around last year after they were mounted.. havnt checked them since lol. Keep meaning to buy a nice low pressure guage, but also keep forgetting 😅

I rode with 5 psi all around and it felt great, mostly trail riding and into the mud and rocks, it took everything I threw at it.

On the stock tires I needed 7psi to keep them somewhat upright. On my 6-ply radial Reptiles, I go anywhere from 3.5-5 depending on terrain. I like the tires to give first, the suspension 2nd, and me 3rd! Makes for a more confident ride. When it gets reversed, I’m not as confident.

They will definitely handle better but the center will wear out so fast. Road is hard on them to begin with, but at high pressur, it's brutle wear.

Wait, that's not right.... Your body first, suspension? What is that?.. Tires last.... Oh sorry.. My bad... That was the old days on the honda 3 wheeler... Lol

With any other tire I would agree,these tires have OVER 500 pavement miles. I'm so impressed with the performance of them, I can see getting 3 or more thousand miles.

Ensuring even wear on tires that see mostly pavement miles is as easy as drawing a line straight across the tread with a piece of chaulk. A lot of people I know with trucks that run mud terrains do this to ensure even wear. I need to do this with mine.. but keeps slipping my mind lol.

You draw the line across the tread, drive a couple hundred feet, and see how much of that line has disappeared. If it's worn off in the middle, and still there on the sides, you lower psi and try again... to get the most even wear you can you just keep lowering the psi until the entire line is gone when you stop and check.


Obviously, a lot of atv tread patterns won't really allow this.. so kinda useless info for wheelers but.. yeah.. great for trucks!

Drive thru a water puddle on concrete. Watch the shape of your contact patch where it leaves water. Let’s you know if it is under / over inflated.

I would say about 6 psi or 7 psi on the stock Mu19 and Mu20. That seems pretty stable in a drift or if you are on the side of a hill and your front tire drops into a rut, you dont feel the tire try to fold a little.

The Bearclaws Im around 5 or 6. I guess i really like the stability. But Ive always been a drifter.

Even on my bicycles through the years, I always wanted my tires more firm.
