Best tyres for the karoo to coast

[eddy]

 

mmmm, more surface touching the road, more friction.

I'm open to be proven wrong though ... would actually be quite interesting ... anyone?

 

Google.

 

The work on width and pressure has been done.

Am I the only one running Conti's .......

[hboli4]

I also stick with what I have and works, leaning towards the heavy and bulletproof rather than fast and light.

 

I'm running a 2.25 Maxxis Ardent in front and a 2.1 Maxxis Crossmark at the back, LUST versions.

 

I guess something like the Spez tires mentioned earlier or even Kenda Smallblock 8's or Crossmarks all around might be a good choice for this race.

erm...tubeless?? Its a freaking dirt roadie race.

 

You've spilled some stupid drivel here before. But this, this comment has to take the cake.

Thanks man you're a great help...

Ok here are some research from GOOGLE!!

Quite a few more variables to look at if you really want to make an informed decision.

 

I personally run 2.1s I might change to something a bit more grippy if riding lots of damp forest tracks, whilst up here in GP I tend to ride Maxxis Crossmark or similar that have a good combination of grip vs speed and durability.

 

All IMHO of course.

Yeah, I read it somewhere but I can't be arsed to actually post a link so I'll just tell that I have read it but I can't remember what it actually said otherwise I would post a precis of the actual results of the test that was done sort of post.

 

A bit like a response to a question posted to which a valuable contribution of "doesn't happen to me" as a reply.

Easy Rollers preferably no wider than 2.1. Unless you a serious (read pro) snake this won't make the biggest difference, what will make the biggest difference, it's too late for now

What he said... Tyres wont make much difference now.

I was actually going to keep very quiet as I will be accused of trolling and adding no value again.

[Wyatt Earp]

At the OP.

Do you know if there is rain expected, I did this "roadie mtb event" in the pouring rain once, it is indeed an entire different event if it rains the whole day.

ha. There's value in my comment. Maybe she'll think before she types.

Not necessarily true.

 

If you reduce the weight of your tyres from really heavy at 900g to some lightweight thin sidewall tyres weighing less than 600g your saving in time for the same amount of energy used will be about 4 minutes on a 5 hour time. And that's just weight, not rolling resistance impact.

She had lots to say about the Spruit and her sport.

That same Spruit ,the where allegedly I have said I never ever ride.

I am still looking for where I said that.

 

OP, dry conditions get the fastest rolling tyre you can find.

[GreatGusto]

I ran my normal tyres last year with 2.4 bar, which are normally at 1.8bar for technical trails like Hakahana. The K2C uphill stretches are long and smooth, and are about 80% of race time, so if you're careful on the descents, the extra pressure makes climbing easier.

 

My humble opinion. No flaming.

Thanks man you're a great help...

 

It is a pleasure, glad I could help.

 

Or did I miss your sarcasm and you expected me (who has no further interest in the matter) to Google it for you and to post it because you couldn't be arsed to find the answer to your own question.

 

 

Yeah, I read it somewhere but I can't be arsed to actually post a link so I'll just tell that I have read it but I can't remember what it actually said otherwise I would post a precis of the actual results of the test that was done sort of post.

 

 

Exactly, see above.

Not an expert by any stretch and it's a fine balance between pressure and size - basically the theory goes, the harder and thinner the tyre the more it bounces over an uneven surface creating more rolling resistance than a tyre with lower pressure and slightly wider, the latter tends to adapt to uneven terrain more (quite obvious actually) and roll's over far easier instead of bouncing, creating less resistance which means the watts you are exerting will be put to more use. And the more uneven the surface becomes the more effect it will have...but as I said it's a fine line. on a Ride like k2c i would drop my pressure a bit as there are no tech/rocky/rooty sections where i need to be protecting my rims and avoiding pinched flats. Do a test on a corrugated road, start with a high pressure and then start dropping it...you will find a comfort zone most probably about 0.2 bar or so less than you would normally ride which will be faster and far more comfortable i.e. saving time and energy with something so simple.
