Getting for our first trip this year to Royal Blue I bought my wife the MSA M21 Beadlocks and after much thought bought 30x10x14 Blackwater Evolutions. We have a big rocky desert trip this summer planned to Sedona through Grand Canyon area so a tamer mud tire was out. Rock, dirt and hard pack was in.

The Evo tires turned out to be the exact height of the Silverbacks. Measurement was taken at highest lug point of each tire with Silverback still on vehicle and bearing weight.

During…

After. The measured pressure at each tire is 4.9lbs. Almost no visible tire pooch. The ride however was hugely different. The lugs can still be felt on concrete but the ride is 10 times smoother.

Doesn't really stick out a whole lot further. The widest part of the new tires front and back are covered by the fenders of the XMR. Barely.

Looking down over RH side.

Back tire RH side. The wider rim can be seen here. The Evo tire itself is almost the exact same overall width as the 9" Silverback. Because of the extended side lugs on the SBack it is much wider than the 9" body of the tire.

Backside…

The overall width at the front tires was 50.5". The M21 comes with a 0 offset so its a 3.5,3.5 rim. I thought the overall effect would be wider but it wasn't.

So...I already bought the MSA's. Was getting ready to order the tires when I found this thread. Overall how pleased were you with your choice of tires. Any thing you would have done different?

I'm happy to hear that because I have the exact same set-up sitting in the garage. M21 15" rims and 30" Evos. Now I just need the machine to get here.

Very interested in these tires. Pleas keep us updated. How high do they measure? How do they do on the trail, mud, rocks. And last but not least how do they wear? And would you buy another set?

Thank you and nice looking bike.

So what's with you guys buying purpose built mud machines and putting trail tires on them over say, an XTP with a bit more suspension travel and geared more towards trails? Or are you still running the backs in the spring mud and running the trail tires the rest of the year? Just curious.

The silverbacks get chewed up on rocky trails and don't provide the smoothest terrain, basically the xmr has the nice features to safely travel through deep water without the risk of ingestion of water and has the more ideal lower low range and the beefier rear diff, basically the only sacrifice an xmr has over the more trail orientated XTP is just the extra suspension travel. I personally kept my stock silverback tires and rims for mud riding in the spring and summer so basically have the best of both worlds with having a second set of tires for the xmr.

We mostly trail ride but there is always moderate mud and water. A few times a year, mostly in the spring and fall, we head out for mud runs though and it's nice to have the machine to handle it. I also plan to keep my silverbacks to switch out for those situations. I might upgrade the shocks in the future but we don't ride fast so they might be ok as is.

I could have purchased an XMR for what the XT-P sells for (and I would not have had to add the snorkel). But I was worried about suspension travel and top speed limitation. But I also did not know about the GP shocks and getting the stock ecu reprogrammed right here in NC at Griffin Performance. So idk which is the better bike but I do think the XMR looks better. And I like the look of those Black Water Evo's on the XMR. Good job, Keep us posted on how you like them.

I'm likely getting the same set up. Waiting for a bit of trail riding feedback. Is the yellow writing on the side of the tire only on one side so you can have it either inside or out? Or does it clean off. Just wondering. Most you don't see it. Also wondering if there's a difference in ride between the 14 and 15" rims. You would think the 14" might be a little more forgiving but some have said the sidewalk is very stiff so maybe there's no decernable difference.

Do you have a lift?? XTREME do those tires rub at all

XTreme

· #18 · Feb 7, 2016

No lift. I don't know if they rub or not, as I screwed up my back, and haven't been able to ride it. BUT, the tires are a tiny bit smaller than the stock Silverbacks, so I can't imagine that they'll rub at all.

No. They don't rub. You can soften the preload up a bit on the shock as well if you want to smooth out the ride as well.

They won't rub at all. The package should be a blast to ride.

I am hearing all of the new 2016's have the lower low. Maybe somebody else can elaborate on that.

But yeah, these 30" trail tires let you keep ground clearance too. There are so many setups we all can run and switch up for different rides.
