New Maxxis tires - rolling resistance?

John_Carter

Hello,
I just replaces the tires on my Cube Acid (2013) deom twh Schwable Smart Sam taht came with it to Maxxis Minion (front) and High roller 2 (rear) 29" - I took them for a quick stin in the park (mainlyon tamrac) and was suprised at their rolling resisstance - I really felt how much more force I need to get them going...

Both tires arethe 'non-sticki' cheaper, single ply version

Weight wise, the pair is only 220g heavier than my previous tires - and while it's rolling wieght and all that I can't see why they would be such a dramatic difference? They did preform very well when I had an opportunity to cycle through some very muddy grass opatches...

Is it because they are new? Do tired have a 'burn in' period?

Thanks!

Nope, they are chunky tyres. Smart Sam are not.

Well done for spell checking that post.
A knobbly tyre will drag a lot more than a slick.

Thanks,
appologies for teh spelling - bloody Autocorrect... ;-)

If I'll go tubeless would that help woth rollign resisstance? Wouls have a bit of weight and run lower pressure on the tires, no?

Thanks,

No.

Minions and high rollers drag considerably more than Smart Sams.

Tubeless wont make a difference.
Lower pressure increases drag.

Auto correct that doesn't correct.

Are you using them off road? If not get some slicks.

Yes,
The idea is to use them off road, I wnated a quick spin in central london so Regent park was it.

Tubless doesn't help with weight and rolling resistance? I see conflicting advice in this regard...

Weight, it can do, rolling resistance, only makes it worse if anything.

Tubeless gives a very minor reduction in rolling resistance. You have got the wrong tyre for what you want.
Ideally a cyclocross bike is what you need, not an mtb

Trust me, I need an MTB ;-)

The Smart Sam has a near solid centre run of tread, also the wire bead ones have a very hard compound which reduces drag. The Maxxis have neither but will work off road in normal British wintery (11 months of 12) conditions.

Not if you're riding a mix of road, gravel, muddy grass and dirt trails. Mountain bikes are no good on roads.

The roads bit is a tiny portion...
But thanks - I do appreciate the good intentions.

The knoblier the tyre the more resistance they will ecounter.

I have loads of different tyres and used to switch them depending on the conditions, then I got in to running tubeless and found it such a PITA to change tyres I ended up sticking with the same tyres (knobby nicks) all the time.

Having recently had a problem with my rear and having to stick a tube in I put an old Dirty Dan on the back. Much knoblier and a huge improvement in traction and grip so I have decided to give up on 'tubeless' and stick some slime tubes in. I know that is a bit of a weight penalty and they are also pretty uncool, but after the success that a friend has had with them they seem to be a good option.

So, that's a long winded way of saying, keep both sets of tyres and switch to the most appropriate for the kind of riding you are going to be doing.

Unless you spend most of your time blasting down black runs those tyres are probably a bit OTT. You'd be better off with more 'all-rounder' tyres like Schwalble Nobby Nic, Continental Mountain King/X-King, Maxxis Ardent, Bontrager XR4/3. These will offer decent grip but with much better (less) rolling resistance.

Thanks guys,
I'm not doing black routes (yet) but so far very happy with the tires. I'm not hugely concerned about rolling resistance as part of the reason I'm into cycling (other than the fun) is that I want to get fit - so more resistance means better fitness, no?

Thanks again for all the help!
