Hey guys,

Requirement: To find a pair of lightweight tyres that would suit the following use.

The bike in its current form: Kona Stinky deelux 08 with 170m rear travel and Marzocchi 66 ATA's upfront. its a 9 speed with a 32t front ring and a 34-11 rear. I have built this bike from a new frame with all 2nd hand parts, the bike weighed in at 19.5kg with 888's upfront, but now weighs about 1kg lighter with the 66 ATA's and the Maxxer semi slick up rear, but unfortunately the semi slick is a bit too treatcherous for the type of riding we do.

Riding: I love a bit of downhil & jumps and do alot of riding over dartmoor, however dartmoor has a bit of everything, tarmic, slippery wet grass, gravely and rocky descents and lots of mud!

I really enjoy dh but my bike is far too heavy to keep up with my friends who all have hardtails so I am on a quest to lighten my bike, with a fork change and rear tyre change my bike has saved over 1kg, I am now looking into buying an RP23 or a DHX air 5 to save more weight and make use of pro pedal which should help my on the steep climbs and help me keep up on long flat runs. We currently do runs of about 17.5k around dartmoor and I would eventually like to be able to do it without having to push the bike up some of the hills!!!

So after a few close moments last week where my rear tyre decided to give way I am looking into more of an all round mountain bike tyre which is fairly lightweight and won't try and kill me, I have heard that narrower tyres r better for slicing through mud but how would they work for wet grass and grip over lose gravely terrain? I have just come across the Panaracer Fire Mud Pro, these have fairly decent sized nodules and are very light at 420grams. My original tyres weigh about 1kg each, and my semi slick weighs 775grams. if I went with the panaracers I would save another kilo at least!

Any recommendations would be greatly appreciated as there is just sooo much stuff to chose from!

Cheers!

Is tubeless possible?

You don't want to go too light or the bike becomes a bit pointless. To be honest, it doesn't sound like the right bike for what you do and IMHO, that you'll end up with something that isn't ideal for what it was designed for or what you intend to use it for.

I am trying to turn the bike into a long travel freeride bike that is able to go uphil as well as down, the reason why I went with the kona stinky frame was because of the long seat post, I am able to get the seat down for the downhill and up high for the ascents, I am trying to lighten the bike but still want it to be able to take hard landings.

You either have skinny tyres to cut through mud or high volume tyres to take big hits. Or settle for the middle ground, something like a 2.2-2.35, 600-700g tyre.

No idea what rims you are using, but I also wouldn't want, for example, a 45mm wide tyre on a 23mm wide rim. It'll just add to the recipe for pinch flats.

Hi,

I am pretty well up to speed on most components available but never really took time until now to appreciate the different types of tyres available. The wheel set I have on my bike at the moment are a set of Superstar Trizoid AM with a 30mm external rim width. Pretty good set and have taken a beating so far.

Something like a single-ply 2.35 High Roller would fit the ill perfectly - IMO I wouldn't want anything smaller on a bike of that size.

Or, for a bit more speed and less weight at the expense of a bit of grip: 2.35 single-ply HR up front, and a 2.25 Maxxis ADvantage on the back (size up BIG). I ran that combo on my Spicy (funnily enough also with 66SLs) and it coped great with the Alps and UK riding. The ADvantage is quicker-rolling than a High Roller so gives you more chance of keeping up...

Draggier than a very, very draggy thing!

1.8" on a stinky is a bit crazy IMO. If you had a super light bike and you rode in really muddy conditions that the tyres are designed for then maybe it would work. With a bike big you will just push the tyres beyond what they are designed for, unless you just ride XC trails all the time on a DH bike?

Go for something fast rolling but light-ish.

Schwalbe Fat Alberts, 2.35" and around 650g. Good all-round tyres that will work all year round.
If you want to go lighter then 2.4" Nobby Nics maybe around 550g. Lighter still, Racing ralph 2.25" are 500g.

Fat Alberts are good tyres, but slow. Racing Ralphs are very fast and light, good in dry conditions, but won't be brilliant in damp or muddy conditions.

Mountain King Supersonic is the best compromise I've found. Light, fast, relatively good grip, not fantastic in mud but OK.

I think if you are going to use a lightweight tyre for downhill, you will be forced to use a tubeless kit to avoid snakebiting. There is no weight saving over tubes, but rolling resistance does drop.
