What do your run your airhead tire pressure at?

Looked up the manual and didnt find anything. Tires say 42 max. Just got a new rear fender with factory stickers with MUCH lower numbers. So wanted to find out what the consensus was. This is for my 74 /6. Thanks!

I have heard that modern tyres need their listed pressure, not what the bike calls for. Mine (stock) on my 1978 R100RS are listed on the dashboard, which is cool, but I think they are wrong. I am going to top them off tonight per the tyre sidewall.

My S fairing tells me 26/29psi (front/rear.) I don't trust that. I usually run 32 normal and 36 with a load on the rear tire. Keep in mind...I'm like a buck 25 at most in weight.

I've kept my front at 30 and rear at 34 for awhile now. That just seems to handle best over all the rain grooved highway I'm forced to navigate. Least weave. I tried lower and higher front and rear, and this seemed to non-scientifically weave less.

My S fairing didn't have the tire pressure decal and you can't, as far as I know, buy another. Lawyers and all that. 26/29 sounds about right for 35 year old specs. I run 33/38, but I'm a fat ass.

I used the 10% rule to get those. Reg Pridmore told me to run around 29 or 30 front and back if I was to take one of his schools. More grip according to him.

Haven't checked the availability lately, but I bought my "S" fairing stickers from Motobins some years ago without any difficulty.

I run 20 front and 25 rear with my K70's and love it.I used recommended pressures on the normal road tyres - 32 and 36.I fitted a Spitfire to the rear earlier this year and found my chicken strips went from 10mm to 20mm...it seems to be a rounder tyre.I'm not so confident on these tyres.

A couple of weeks ago after not riding the bike for several months,I went out,and after getting the feel of the bike again got into the zone and was pushing the bike hard,I felt the most confident on the bike with these tyres ever.Getting home I found I had no chicken strips at all,it was right down to the edge.I was suspicious,and checked the rear tyre pressure - 8psi !!!

It appears I'm very tolerant of low pressures...and high pressures feel greasy to me.Maybe riding trials bikes at 3 or 4 psi for 30 years has distorted my perception.

I ran my Macs on my /7 at 32/ 36, but the Lasertechs are fine 4/5 lbs less, and this is the pressures the suspension was designed to work with.

The Distanzas on the other bikes are fine at 26 /30 but that is a compromise for dual sport use, although the only real drawback is a little scalloping on the front - handling is great.

I'm surprised at the wide range folks are running street tires at. I'm usually at 30-32 front 32-34 rear.
