knobbly road pressure
 

running Mich T63 up front and mitas E0-9 rear.

Off road i use 25 - 22ish PSI depending on the terrain. But on road i can not decide what pressure is best for tarmac.

I've tried 22 up to about 35PSI...i "think" i prefer to stay at a lower pressure even on tarmac...say 25PSI? but next week i'll prob change my mind and put the pressure up....then down again.......then up and so on!!!!:009:

What do you guys reckon?

I use these at standard as per the book pressures on and off because I can't be bothered changing them. Works ok.

I used to faff about lowering pressures to 22psi front and 26psi rear for off road, but gave up partly, like Jimmy because I can't be bothered when swapping from tar to trail frequently, but mainly because in mud and on soft ground it didn't find it made any real difference. On the road (with a TKC80) I'd be running 29psi front and 30psi rear (33psi fully loaded), which I find doesn't positively or negatively alter the handling, but does slow down the inevitable squaring off of the rear tyre. With road orientated tyres I stick with OE 30/33psi pressures.

really?? i find it makes a massive difference. example - Last friday rode over some fields, looked fine but all three us found it a tad slippy. We were on higher pressure as we had been traveling some distance by road. Dropped the pressure....hey presto! Was then ragging round the fields with far more grip.

I rode home the other day fully laden on 23.5PSI rear and 21.5 PSI front, i think the bike feels better than when i rode out at around 29 PSI.

It is a faff though changing pressure, im with you on that one.

seal.. 28 / 30 hot
dirt/gravel 18 / 20.. even go lower at some times if I had rim locks..

Ah, rimlocks... I'll have to deal with that issue - manana, maybe...

I used D606s on a couple of Husky 610Es, but found that open-road use with 26psi (rear) caused shedding of the centre knobs, which is a strange feeling. Lower pressure seemed to be ok, and the tyre would last about 4000km of varied use, including highway operation.

I guess what I'm saying is, that based on the above, I have found about 20psi works for me with knobbies. They usually have hard sidewalls, so with heavy-duty tubes 20 is plenty imo.

Yer I must buy a set...
next time I do a tire change..put them in...
