K9 vs XTR370 vs Roxxzilla vs BFG KM3: SxS Tire Comparison At Windrock Offroad Park on Trail 16

Before you buy your next set of tires for a SxS watch this video. You may be surprised. Sxs tire comparison on trail 16 at Windrock. In this video I decided to compare some of the newer SxS tires against each other in some unofficial, totally unfair competitions that nobody knew I was doing. LOL. All of these tires were 32's. The tires were mostly new to brand new. I took Supergrip K9, System 3 XTR 370, Maxxis Roxxzilla, and a set of BFG KM3 tires. The SxS's in this test were Polaris RZR turbo 4 seater, Polaris RZR turbo 2 seater and Wildcat XX. Make your own decision to which ones did better. The conditions were pretty slick hard pack and rounded rocks. Windrock offroad park has some amazing trails. Trail 16 was really fun and the conditions were perfect for riding, a little slick with no dust. If you liked this video please be sure to subscribe. Thanks

I want to ride with you guys. I live in oliversprings tn Right by windrock

[@GrimRZR]

@@singletrackmarc819 I don't get to ride Windrock as much as I would like

[@jjadventures6655]

Looked like you had a fun time. I love the smack talk.

[@GrimRZR]

I think that is the best part.

[@LNMlife]

Hello it was awesome video I just subscribe your channel keep up the good work 👍♥

[@GrimRZR]

Thanks for watching and the sub.

[@matthewshort2315]

Great video, I feel like videos never really do justice for ruts or hills compared to being there.

[@GrimRZR]

No doubt. Thanks for the feedback. This was a fun trail.

[@craigbuscio8167]

What tire would you chose out of the K9 or 370 for general trail riding with no rocks? Thanks

[@GrimRZR]

I'd say the K9 will last longer but the 370 provides better off-road traction.

[@codylight6488]

The key to k9's are very low air pressure! If the tire is not bulging on flat ground you have too much air pressure. Start at 6 psi and adjust from there. Just some advise. Have a fun riding and be safe.

[@GrimRZR]

After our testing everyone that bought K9's sold them.

[@jackadamz3]

You are right about the pressure. 8psi is max for traction. The k9s do good in loose rock and terrain. Not so well on slick rock.

[@GrimRZR]

@@jackadamz3 I seen some K9's that were cut and siped that softened them up good. He said they work much better than before he did it.

[@pete1735]

To me the k9s are just way to hard I would rather have a carnivore than k9s

[@davidlevy2725]

Did anyone consider the system 3 XCR350? I can't decide between these, the KM3, and tusk terrabites. I live in Utah so most of my terrain is very dry. I'm looking for something that can take corners at speed great, good at rock crawling, and pretty good in sand and snow.

[@GrimRZR]

I haven't ran them personally but they seem decent.

[@chriskocienski3601]

I have the 370s and haven't found anything they can't handle yet. I love them

[@GrimRZR]

They do pretty good

[@chriskocienski3601]

@GrimRZR yeah I live in upstate NY so we have a little bit of everything, mud, rock, hard pack trails and they perform really good. And I have them on a havoc X

[@markmanning6773]

The KM3’s look like they did pretty good. Thoughts?

[@GrimRZR]

They actually did pretty good. I actually just got a set of Roxxzillas so I will be able to tell between the XTR370 and them on my machine.

[@markmanning6773]

I may wind up getting a set of roxxzilla’s but I really want something different because I don’t ride just rocks. Getting more and more to where I want to run fast tracks but I still love rock crawling. Very difficult to find a tire that excels at both of these

[@markmanning6773]

I am very interested in your input as far as 370’s versus roxxilla’s. There’s no question rockzilla’s will be better in rocks but the big question being are 370’s is good enough in rocks while being really good at other stuff. I guess both are a little on the heavy side

[@GrimRZR]

I don't think I would get either of these for going fast. The 370's were awesome. I just can't say which are better unless I've tried both.

[@dakotaskeens2025]

Mark which ones do you prefer

[@jimmace6148]

Are these Wildcat guys wheeling in High gear?

[@GrimRZR]

I don't think so. He had just installed a clutch kit and I think he found something adjusted wrong or setup for the wrong thing

[@MrsGrimrzr]

Look how short Marcus's beard was !

[@GrimRZR]

It was a long time ago

[@bowie4563]

i wish i was there!🥺

[@GrimRZR]

Me too.

[@Smak-jt4eg]

Chicane and they are great! I wouldn’t have anything else.

[@GrimRZR]

Nice. What are you running them on?

[@markmanning6773]

In rocks?

[@chroniclesofnanner9543]

Turns out that having k9s on your rig disables your ability to hit the gas pedal

[@GrimRZR]

Maybe just at the right time.

[@VertigoPerformance]

The last buggy went a different route

[@GrimRZR]

The right line makes a difference

I can hear flashlight now.................

He was having a rough trip. Lots of things didnt go his way so far.

[@head458]

@@GrimRZR Be glad I'm not there with the terabites. I'd show err body up. LOL

[@GrimRZR]

Maybe next time.

[@rugby3874]

If you got ground cleared you can make it a lot better

[@GrimRZR]

Very true

[@trips2uranus]

100% driver

[@GrimRZR]

This may not have been a completely fair comparison

[@traceyhewes95]

Ole boy in the front was too busy listening to his blow off valve and not driving for the conditions.

[@GrimRZR]

We all had fun aggravating him about those tires

[@alexbell9196]

Who the heck taught these guys how to drive?

[@GrimRZR]

We were never taught. Just go out and ride around
