Maybe just bad luck but I got two sidewall cuts in three rides on two different ikons. I was running them on some flow ex rims at 30 psi. I liked the volume and traction but my dhrii tires hadn't let me down once. Are tires with 120 tpi that fragile compared to 60 tpi? They were both exo sidewalls. I'm thinking of trying the ardent 2.4 to get the larger volume for my hardtail.
 
I'm going from Ardent 2.4/Ardent Race 2.35 to Ikon 2.35/Ikon 2.35 on Flow EX rims on my hard tail 26er. I'll be running my normal 18f/20r psi unless it's really rocky where it'll get bumped 2psi each end.
I can't imagine running 30.
 
Just picked up an Ikon 2.35 that I'm not sure will be better front or rear? I was thinking front initially, but seeing others here running rear as well, or both f and r. The other new tire I have to go along with it is a Barzo 29x2.35 TNT that I had planned for the rear. Both wheels have 30mm internal when I want to go up in tire size. These 2 xc tires will get the most use and will probably air them up and see which has the most volume. The tire that wins (volume) will most likely go on the front. High hopes for both tires and crossing fingers for much traction/speed!
 
I run the Ikon 2.35 both front and rear and really like the tire. Looking at the tread pattern of the Barzo, it reminds me a lot of the X-king, another tire I really liked, and if having both tires, my decision would be to try the Barzo up front and the Ikon out back. The Ikon has almost a center tread that might roll better under your weight than the Barzo, while the Barzo has a offset lug that I'm thinking will cater to grip up front. Just my worthless two cents. Honestly, it's probably a coin toss! I also think your idea of putting which ever one ends up fatter up front is another good thing to try. Who knows, maybe the Barzo out back would be better too.

Interested to hear your opinions on the Barzo. I personally have always run the same tire front and rear so curious about your impressions.
 
Just installed Ikon 2.35 Front and rear on my 29er full susp. Was impressed on how easy it was to setup tubeless with a floor pump. Excellent grip and feel. I have to say though I was expecting they would roll a bit faster. Might be my imagination though. Previous tires were 2.35 Ground Controls. Running them at 20 psi, RW is about 165.

The interesting thing is on the same course with these tires I'm finding I'm using a bit less travel in the fork and rear shock. I'm assuming it could be due to how voluminous these tires are and that they may play a more significant role in the overall suspension.
 
my singlespeed set up is Ikon 2.2 on the rear (light, fast and good bite) and Rocket Ron 2.2 on the front (light, fast and great bite in corners). Both tires on wide carbon rims and look and feel bigger than 2.2 size would indicate.

I have always done he BMX set up with a 2.35 on F and slightly smaller 2.2 on Rear but the IKON / RON combo is keeping me happy at the moment
 
I had Ikons on my bike a few years ago. There were not well suited to our conditions-very rocky, with big chunks, or loose over hard. I found them to be completely insufficient 85% of the time. I took them off after 100 miles or so and replaced them with Ardents, which I have been riding for several seasons now.

Then one late Saturday last fall I found a deep slash on the sidewall on my Ardent rear tire. It was too late in the day to get another new replacement before a big Sunday ride, so I grabbed the take-off Ikon 2.35 (which I used as a front before) and spun it up on the rear. I rode it until it was dead.

When I had that tire on the front of the '12 Superfly FS, it didn't work (for me). Then when I used that exact same tire on the rear of a different bike-'16 Fuel EX 9.9-it worked excellently.

What do I make of all of this? In the few years between first trying the Ikons, my technical riding, fitness, and overall ability has gone up (sometimes way up) and the new bike has better geo and suspension. which makes exploiting the qualities of the Ikon easier.

That all said, when I replaced the used-up Ikon, I got an Ardent.
 
I have run one on an i39mm rim and it worked well, but not for the intended purpose I was trying to use it for, as with so much sidewall support it wasn't very plush, even at low pressures, had to drop pressure too low to feel good and got rim strikes (this was on my rigid on the rear), other than that it worked fantastic on the wide rim, also have run it on i29 and i25 good on those too, although prefer it on wider rims than the i25.

I mounted 2.35 ikons on a 32 ID rim and the thing looks great. Almost looks like it was made to be a plus tire. I havent got a chance to ride yet though.

Anyone try this ?

I tried 2.35 Ralphs on the 32i and it was a disaster.

The profile squared off and all the sidewall tread was touching at all times.
This doesn't seem to be the case with the Ikons. ( Not that they have sidewall tread like the RR's but because they follow the curve that they should).
 
Finally got my new Ikon 2.35 Max Speed mounted to Hulk bike i30mm carbon rear wheel. Also had a Barzo 2.35 mounted to my front XM481 wheel. I have to say that the Ikon edges out the Barzo in the volume department. Had em both at 40 psi max and the Ikon won by about 1/16 inch. I still ended up putting it on the rear based on better tread pattern and more knobs than the Barzo for grip out back. The Barzo is also an awesome tire in its own right and has wider spaced knobs that are a hair taller too.
Was able to really test this combo out on the trail with mixed wet/dry/mud conditions after some good rainfall. Both tires gripped very well in all conditions and felt very fast to me. The Ikon especially performed well on the back...the grip and speed were fantastic all around. Deep mud was only place these tires lacked in. Gravel, roots, rocks, hard pack (all slightly slick) felt in control. These will both be my trail and racing tire setup for this season....blown away!
Front: 21 psi
Rear: 20 psi
