2020 400 Coleman HiSunUTV 393cc Side by Side Excessive middle tire wear

[John Gubancsik]

Does anyone know why the middle of my front tires are wearing too fast?  I just checked the pressures, and they were at 24psi.  The manual says 10psi. Could that be the reason, but why aren't the rear tires showing excessive wear?  I've attached photos.

Any suggestions would be appreciated.

You've answered your own question. The pressure is way too high. It's only running on that portion of the tire and the fronts wear faster than the rears because they take a beating from steering, especially on hard pavement. You must also have a very hard ride. Get the pressure down to the recommended level.

Yup, as been mentioned it's way too high. They're pretty stiff sidewalls so you can get away with the lower psi. I think I only use around 6 or 8 psi in my Landmaster and seem to be wearing ok.

Be aware tho that most tire manufacturers state the max weight when stating the air pressure. For example, in a car you have passengers in all the seats and a full trunk. Most people don't drive year round like that. Unless I'm doing heavy work I rarely have the max pressure even in my tractors.

 The low profile tires on cars are a bit more finicky tho, just have to experiment.

I'd be careful though on going too low with car tires. At long highway/interstate speeds low pressure can cause the tire to overheat and have a blowout. Extreme case but it does happen. Same with too high pressure but because higher temp at speed causes higher pressure, even worse on hotter days.

Well that goes with common sense too I guess. In a Hiway vehicle yeah, 5 or 10 psi below the maximum is usually  more than enough. But then again, if you load it up for a trip across the country you should definitely raise the air up a bit. In general air it up for the usage you're driving most of the time and the tire wear should be good. I used to drive quite a few miles so I kept an eye on the wear. With my PU and trailer when loaded I did find that it handled much better at the max rated psi.

 Off road smaller UTV and the like usually the tires have a much stiffer sidewall anyway and it's not like you'll be doing 70+ MPH with it for hours on end.

OK, thanks everyone.  I'll run at 10psi and see if that helps.  I probably used the number on the tires.
