I ran 2.8 RoRo on I35 on my m3 without issue.

 

I ran Nobby Nics 2.8 on mine, great bike. To tell you the truth, I think it would be better with 2.6 tires. For me, the 2.8's while they allow to run low psi, they rebound/deflect more than I like. Good Luck!

 

I had a 2.8 Rocket Ron on the rear of my Mojo 3. 30mm rim. The tire would hit the frame on every jump/drop.

I switched to 2.35 tires as a result. But, despite Ibis' claim of no diameter difference between regular and plus tires, running 2.35 lowers the bottom bracket appreciably. It's enough of a drop to make pedal strikes a significant issue, depending on where you ride. Disappointing, for sure.

Have no time on the following so I can't help there but I am finding 2.6 minnion dhf and 2.6 recon to be the sweet spot for traction and rolling resistance on the trails I ride with the mojo 3. Smiles for days on this bike

 

This is part of my dilemma. Within 8 minutes I am getting replies that don't confirm one way or the other. I don't want to be the stimulus for any bad blood, but I have no way to demo the set up I want to run (RR 2.8), and I have read there are clearance issues. I had a Ripley V1 that had tire clearance issues. Absolutely LOVED the bike, but could not run it the way I wanted and had to look elsewhere. Hoping to not repeat that. If the tire hits on BIG drops, that may not be an issue as 90% of my riding is tight technical riding with short steep climbs and drops. I am looking for the most playful bike I can get that will run 2.8's.

 

Are you set on Rocket rons? I was interested in those for my mojo 3, but am running rekon/dhf 2.8 on 35mm rims and am very happy with them. They run narrower than 2.8 so no worries about clearance on either bike.

 

Some of the early m3's had a suspension link that would rub under impact but they fixed that issue.

 

AHA!!! This would explain it. Moving forward, my confidence is restored. I appreciate the insight folks.

I am not totally set on just the RR, but I have spent the last year testing tires and sizes (27.5+, 29, 29+) to determine my next DD, and the RR was good enough in my area to build a bike around it.

 

I have run rekons, nobby nics, dhr2, and currently on a slaughter. The only time any of them rubbed was when a rock got caught in the side lugs. All were 2.8’s on the rear.

 

I’ve been running a rocket ron 2.8 mounted to some wide derby rims for the past year and haven’t had any issues. I also ran a Nobby Nic 2.8 before that and it was fine too.

 

Why do you necessarily need to run 2.8"? Why not 2.6 for instance, getting the best of both worlds + additional tire clearance.

 

For me personally, I didn’t feel I got the same traction and comfort out of the 2.6 compared to the 2.8. I’ve also never had any issues with clearance running 2.8.
