Doing the geeky-tech talk on todays ride. And the conversation moved to what width tyre is best on the back of a 5-6″ susser.
I tend to use between 2.1 and 2.4 … never bigger or smaller.

Was surprised to hear one guy never rides anything wider than a 2.1 on his. This is not his race/marathon bike .. its his 140mm play bike.

Anybody else ride narrow on the back of a 5-6inch full-suss bike?

Yeah, 2.1 Medusa (more like a 2.0in really) at the moment.

It is v muddy out though.

2.25 Nobby Nic seems about right for me. If Contis, tend to stick to 2.2 tops.

2.3

Yeah 2.2 Conti’s on mine. Nothing more than 2.3 though it does vary by brand.

i’m using 2.3 minions

2.35 & 2.5 those 2 sizes are all I’ve used on my Pitch, although 2.35 Eskars are a fair bit bigger than 2.35 High Rollers 🙂

marin 140 wolfridge, used for local dh and trail riding

2.1 mud-x
2.2 crossmark
2.35 high roller
2.5 minion and high rollers

that covers my range of tyres. 2.5 are just for dh, don’t ever ride up anything with them

Gone from a 2.4 front and 2.1 rear Kendal Nevegal combo, to a pair of 2.2 Conti Rubber Queens on my Heckler..

Thinking I may buy a 2.4 RQ For the front..

Not sure yet 🙁

2.25-2.35-2.4

2.35 minions anything smaller is for road riding

2.35 – 2.4 seems to fit the bill most of the time.

2.35s here, anything bigger is overkill and smaller wont take the babysheads on my locals, run at 40psi they tick everybox (allyear/allrounders)

2.25 Schwalbe. Either racing ralph or nobby nic depending on season.

Oddly enough though, the Schwalbes in 2.25 are about the same size as the 2.5 Maxxis minion i’m running on the front at the moment.

So it’s either a big 2.25 or a small 2.5 i guess??

2.1 on mine usually (proper sized 2.1 though). Oh except for dh duties when I squeeze a 2.5 highroller into the back.

2.35 Minions. Used to put Pan 2.1 Trailrakers on for the winter but don’t bother now

2.4 fat albert

Let’s not forget that 2.35 Minions & High Rollers are 52-559, so about 2.1 in reality. Other Maxxis tyres are more accurate:

Crossmark 2.1 (52-559)
Advantage 2.1 (52-559)

I tried 2.35 Kendas for a while and found anything they gave me on the downhills was taken away and more on the flat and uphill (plus they can’t do muddy, they squirm), went to 2.1 and it just gives a better balance over the whole ride. I used to use 1.8 panaracer fire xc’s ( which probably measure up to 1.65 in real life) on my 1997 heckler, back in 2002 (4 inches travel but that was big back then), and it was fast but I did buckle a few rear wheel rims and spent some time fixing snakebites but maybe that was just the tyre.
