Maxxis Bighorn Radials on Chrome ITP's

Re: Maxxis Bighorn Radials on Chrome ITP\'s

That is what I thought about the speed with the larger tires. Basic physics tells you that it should be faster, maybe its a false sensation from the tires. I am going to check it with the truck speedometer.
My windshield wiper will not go vertical, what you see is what you get. I got one of the first RTV's put out and I think they have redesigned it or went with a different model wiper. It bothered me at first but I have grown used to it and don't even see it anymore.

Nice "meat hooks"! I looked closely at those tires, but I had a friend who had them on a Rhino who talked me out of them since most of the time my RTV will be tooling around my yard. He promises me that he gets better traction in the mud and snow than I will with the Maxxis Bighorns. That I have no problem believing! However, I wanted to run them year round and didn't want my lawn dug up. I guess since mine are not as aggressive could be why they feel no different in the handling scene on hard surfaces.

Great looking rubber though. If I had an opportunity to go on true off roading trips more often I'd have gone with those tires. At least this way we will get reports on how several different tires perform on the RTV. Heck, you may never need your winch now! /forums/images/graemlins/grin.gif

Dargo,
I drove a friends Rhino around his yard and with the stock tires, it will tear up the grass in a turn because of the locked rear end. Is the RTV rear locked all the time or does it have a differential lock like the tractor, if it's not locked all the time it shouldn't tear up the grass in a turn, unless you go really fast and slide. Gotta drive one of the RTV's, just for comparison mind you, my wife says I can't afford one. /forums/images/graemlins/frown.gif /forums/images/graemlins/frown.gif

The RTV has a locking differential like a tractor, you step on a pedal to lock it in. I have been driving across the lawn with no damage, but if you get into a soft area it will leave tracks. The 589's are a low pressure, high floatation tire that seems to float on mud rather than plow through.
You need to test drive an RTV or any RUV, as I heard that it grows hair on your head and drives the ladies wild /forums/images/graemlins/grin.gif. If you need a work horse that is a blast to drive, this is it. Tell your bride that it will help with her flower garden /forums/images/graemlins/wink.gif.

Dozernut,

You're going to love the 589's in the snow. I run them on my quad during the winter (pic attached) and what a difference.

Question - looking at the front of your RTV, below the receiver is a plate with 3 grooves. What is it?

It is the quick attach mount for the 60" snow plow. The plow frame slides into the attached receiver and you throw two levers. plug in the blade lift and go.
That is a cool looking quad you have, nice looking tires /forums/images/graemlins/grin.gif.

Re: Maxxis Bighorn Radials on Chrome ITP\'s

Got it. Sounds like a good plow setup.
Doubt I'll plow with mine. The quad pictured has a plow but I mainly use the tractor with a 6' blade off the 3-point. The FEL comes in handy to push it away also.

Re: Maxxis Bighorn Radials on Chrome ITP\'s

I just split another load of firewood and loaded my RTV. I can tell you now that 14 psi is too low for the rear with a load. They were sagging pretty bad. I put them back up to 17.5 psi and that seemed to be a good compromise. Dozernut, have you put any weight in yours with only 7 psi? I would watch it closely. If I only had 7 psi in mine with a full load of firewood, I would have been on the rims. I think 14 psi is okay for the front, but I'm staying at 17.5 minimum in the rear. I really wouldn't want to bend up one of my new rims! /forums/images/graemlins/blush.gif When I was comparing tires, I noticed that the 589's and the Maxxix both were 6 ply.

Re: Maxxis Bighorn Radials on Chrome ITP\'s

No. I have not put a load on them yet. I would pump them up for a heavy load. I am also leery of that low psi with weight on them, but for running the muddy trails, that pressure is good.

Re: Maxxis Bighorn Radials on Chrome ITP\'s

You guys are on 2 different pages. The Bighorns are a radial that naturally needs more pressure than a bias ply. The 589's are bias. Therefore, 7 psi should be adequate for the rated load of the tire on most bias atv tires. I don't know specifically, but I'd bet the bighorns need a certain higher pressure at all times to perform like they are supposed to.

I'd also figure if you run the radials at low pressure for an extended period of time, they will fail (like a truck tire), wearing out the sidewall rapidly.

I'm no tire expert, I just have had a lot of experience with atv tires.

One thing is for sure, be VERY careful when over-inflating bias atv tires. I know a guy who worked in a tire shop, and one day he put some new blackwaters on for a guy. While he was airing one up, he rested his hand on the tire. He was putting 35 lbs in the tires (he didn't know better). The bead blew off the rim, with such force that it broke a bunch of bones in his hand. Needless to say he was lucky, it could have been worse.

Sorry for such a long post, just wanted to reveal the dangers of over-inflation.
