What does "too much tram lining" mean?
Because the front tread pattern has two huge “V” shaped knobs, with no centre knob, I found the bike wanted to run in the middle of the tread, and the centre blocks are forced outwards, meaning you’re actually running in the middle of the two huge “V” shaped knobs.

It felt like the bike wanted to go in a straight line between these knobs, and took a lot of rider input to get it on the outside of these/ initiate a turn.

With a centre block it would be much much better.

Interesting, I've not had this sensation.

Anyone know why the difference in sidewall carcass between some of the treads? The MM has this diamond pattern across it all, but the Albert is a regular smooth surface. Figured the diamonds weee part of the radial construction when I first opened the MM but then the Albert looked normal.

If you get a chance, try the rear on the front also. I much prefer it that way.
Agreed. The Shredda Front seems almost like a full wet tire. Think Maxxis Wet Scream if you've seen one in person. I've read a few reviews with the Shredda rear in the front and that seemed the best without being overkill like the front would be for soft/loose conditions. Then the MM in the rear.

Morning Paul

I don't run them; I have in the past, but I don't feel the need.

My friend contacted Schwalbe about inserts, and this was their reply

"Thanks for getting in touch with us, I hope you’re well.

You ask a good question. The construction of the new radial tyres means that you wouldn't really need an insert, in fact as you say, an insert would reduce the effect of the radial tyres. You really want the radials to be free to flex in the way they are designed, otherwise you may as well use the traditional carcass tyres instead.

With the radials, if you use a slightly higher pressure than you are used to, you will still get more grip (due to a greater tyre footprint) and be less likely to ding your rim. I’ve had a couple of my local shops ridding these and hammering them, since October. They ride a mix of ebikes and non-ebikes, all without inserts, and the feedback has been overwhelmingly positive. The only thing to do is to find your ideal tyre pressure, as it will be different (higher) than what you’re used to. Say, if you run 25psi rear normally, then you may want to go up to 27/28. You will get more grip than you’ve ever had, and the rim should be protected too.

I hope this helps, but if you have any other questions please feel free to ask."
Thanks James, appreciate you sharing the feedback from Schwalbe. My LBS have asked the same question of the Sales Rep and didn't really get an answer. I also see Rob's post advising he had a 'pretty big rim ding', so feel its a balance maybe run rear for me at 30/31 PSI and test with no insert as want to get most out pf the radial carcass, plus less of a pain on install, but once rim dinged its dinged!..........🤷‍♂️

I have tried the Magic Mary Gravity on the front and Albert Gravity on the rear and I really do like them.

Also tried the Shredda Front (hated the tread pattern, too much tram lining due to no centre block) and Shredda Rear, on both rear and front, that works very very well, but obviously massively draggy, but insane levels of grip.

Trying to find the sweet spon on the ebike, I initially thought the Magic Mary Gravity both front and rear would be decent, but wanted to try the Albert Gravity out back first. And considering that the blocks are not too tall on the Albert, it offers suprisingly decent grip levels, even with the current muddy state of the trails.

I'm running 28 psi rear and 25 psi front. I reckon I might have to up it a little bit when it dries out a bit and speeds up, as I had a pretty big rim ding on the rear yesterday landing on a root after a small jump.

The tyres are very nicely damped, grip levels seem high. They turn quite well, although, can feel a little vague on the edge of the tyre (completely different to Conti Kryptotal / Argotal on the edges, which feel more locked in).

I might try them in Finale in a few weeks to see how I get on with faster rolling / rock terrain.

For now they are definitely staying on the bike (I have tried almost every enduro tyre out there over the past few years)

Thanks Rob (nice bike, looks so good) appreciated you experienced feedback. Be interesting to see what you think of them fin Finale on faster rolling/ rocky terrain which is more what I ride in Aust. If you can please put a post up. Have fun in Finale - SEND IT!

The benefit of the radials is their higher flexibility allowing them to have a larger contact patch with the ground to provide the better bump absorption and traction. The proper amount of flex there shouldn’t be too extreme though, if you were consent having your tire flex so much the insert would be affecting it then your pressure is probably too low.

Compare the profile of your inserts to that of the inflated tire, there should be a pretty decent sized gap between the top of the insert and the inside of the tire where it’s treaded unless it’s some huge insert, so I really don’t think a moderately sized insert should have any ill effect on the tires that would take away the radial’s benefits. It’s not like you’d be constantly riding on your insert with a properly inflated tire, they should just be there to soak up hits that would normally get down to the rim.

Thanks you and makes sense. I don't have tubeless inserts yet (I have been running Tanus Amour and have had no problems and they are easy so if it aint broke, I just haven't changed) get the Tannus will negate the effects of radials.
So having the choice to buy an insert what would be your recommendation - light and would protect rim but not negate radial effect or just get Cushcore the allow flexibility in future if next set of tyres are not radials

This is what I’m using right now. Definitely not a usual big name brand, but it’s got a pretty conservative profile in terms of size and was actually very light. It was worlds easier to install than my beefy e-mtb CushCores but still seems to get the job done for the riding I do. It pretty much feels like the material pool noodles are made of.

That's uncanny as this is what I have been looking at the SL and the HD version. So if the SL is working for you might give that a try when I put on the radials.

Thank you for all your help, really appreciate it.

SL - Tubolight Evo SL 29in Tyre Insert
HD - Tubolight Evo HD 29in Tyre Insert

Alrighty, after 3 loops on the same 17 mile trail I'm confident that there's no real world affect on battery life. It may actually be a bit better than my MM's, but close enough that ambient temperature and trail conditions will have a larger effect.

I'm really liking the way these soak up trail junk without deflecting, traction is great on everything so far except dry or wet limestone.
Totally agree with you. I just demoed a Santa Cruz Vala that had these tires, and a near silent DT Swiss 350 24t rear hub, and I've never been on such a quiet bike before. It really allowed me to focus on riding and hear how the trail was reacting to the bike. I used to love loud hubs, but now I'm dreading going back to my normal bike with Hydra hubs 😂

You should try an Onyx hub, which is silent, gamer changer imho.

Reading through the above posts, if I wanted to try a pair of Schwalbe radial tyres for all round performance would it be a plan to have Albert Gravity Ultrasoft front and rear? Have done this before with Maxxis Assegai Maxxgrip DD so when rear is worn out just move front to rear and repeat. Trek Rail in South Downs chalky flinty muck in winter and chalky flinty abrasive in summer. Currently have High Roller 3 Maxxgrip DD front and DH rear but they're starting to look ugly. Have tried regular Magic Mary front but didn't like it, don't know why.

Advice please @Rob Rides EMTB

If you're riding mostly soft terrain dirt, sand, silt, mix of smaller rocks I'd say the shredda, if the hard pack with large rocks the Alberts would probably be better.

Changed spiked tires to Alberts this morning and went for ride. Initial impressions: Awesome traction! It will be interesting to see how these work on higher speeds/bike park situations and drier conditions because today was WET! So far my all time/all condition favourite tires on emtb has been: Classic Assegai/DHRII combo and Kryptotal DH super softs. Contis I haven`t ridden so much in bike parks but every where else it`s been amazing. These Alberts are 2.6” super gravity supersoft/soft and these are 2.4” in real life….at least immediately after installation.

Pretty hard to figure it out as it would be based on rider + peculiar bike + peculiar trail T+ meteo.

It's not like the tires are deforming themselves all the time so it could be very in some condition be very limited. If your entire ride is rockgarden or with 90% of roots and you go full speed, yeah I would be incline to see a difference.

Unfortunately, to do a real test would require money & time. In current meteo honestly, here with full mud, drag is so intense that I don't think I would see any difference.

I've been on the classic combo of Assegi/DHRII combo for a few years and moved to Alberts. Gravity front and rear, 2.6 SS front and 2.5 Soft rear. Loose over hardpack, hardpack and rocky are my common conditions in California. They've been fantastic, they grip really well in my conditions and the ability to conform to rocks is noticeable. They do dampen trail feel, which I like but is different from Maxxis. PSI is touchy. +/- just a few PSI will make a difference, easy to go too high or low so it takes some testing to find your sweet spot. I landed on 26 front and 29 rear.

Outside of those conditions, if you tend to have wet/loose conditions, it's more loamy or muddy I'd move towards Magic Mary up front for more side knob bite. Even more towards those conditions I'd put MM on the rear and a rear Shredda on the front. Continuing to the extreme end Shredda Front/Rear combo is like having Motocross wheels on the, knobs are crazy long. Giving Wet Scream vibes.
I run the DHR II up front. That rear shredda kinda resembles it.

It may not be what you are saying ...

... but I am saying "... larger contact patch = more drag = more battery expenditure" 😀
Ummm, yes, but How much?

From Schwalbe web?

Due to the larger contact area with the ground, Schwalbe radial tires always have more rubber in contact with the ground. As a result, rolling resistance increases slightly. However, this can be almost compensated for by clever tread designs, as already demonstrated on the ALBERT, for example.

To slightly offset the increased rolling resistance, especially on smoother terrain, you can also increase your tire pressures compared to non-radial tires and still have increased grip with less impact to rolling resistance. I noticed this after riding a Vala recently and I had my pressures up about 10-15% compared to the Maxxis tires I’ve been running for years with no noticeable downsides, and a still noticeable improvement in grip and absorption.
