Piss poor online fitment guides

My plan was to start her at 36/40 and experiment from there. That was the optimum pressure her previous several sets of Avon Storms and Storm 2 Ultras seemed to work best at.

Where you getting these from? I've had a browse on the web to no avail & they are the tire du jour for TDM's at the mo, rated top of the heap for mileage, out right grip & wet grip. Good price in the UK too, not expecting that so far away from the factory, though.
I have been told that at the ideal pressure a tire will not fluctuate much more than 2 psi between hot & cold. I use that as my guide line now. You want to try finding info for dual porpoise tires......

Is there any reason why the back tyre should have a higher pressure than the front? Does that apply to all different types of bikes?

Rear tyres are usually larger and carry greater weight than does the front. Some bikes have equal pressures front and rear. I have yet to hear of one where the manufacturer recommends higher front pressure than rear.

Also remembering all of the fuss and bother KoroJ had with haemorrhaging Storm 2 Ultras on his ST1300, Mr Avon's response seemed to be that if the bike wasn't listed in their official fitment guide, then one fitted at one's own risk. If that's true, then Avon only manufactures tyres for a quite limited range of bikes.

the ST1300 are very hard on tyres< I serviced a bunch of them for a rental Co not that long ago...

We ended up using ONLY the Metzeler marathon steel belted radials,nothing else could handle the weight and power of MR Lard ass Honda 1300

Having once owned an ST1300, I can state that the Avon Storm suited it fabulously. Regrettably the Storm 2 Ultra wasn't superior to the model tyre it replaced. I suspect that some of the other stiffer carcass construction tyres, like the Conti Road Attack 2 GT could work quite well on the ST.

I just walked out and look at the recommendd tyre pressures on the swingarm of my GSF650 - it says 36/36 .. I did run Pilot Roads (the original, not 2s or 3s) at that (I currently run Conti Road Attacks at the manufacturers specifications of 38/42) ... and had no problems at with PRs 36/36. Have a play and see what she likes.

I've never understood the obsession that many have with exact tyre pressures.
I run the rear tyre on my VFR from 32 to 15 PSI, depending on how long it was since I last pumped it up.
It gets 'sqidgy' below 15psi and 'skatey' above 32 but I don't notice any difference between those numbers.
I've always been guided by my own experiences in such matters.

Fwark!!!!!

And Fwark again!

Fwark is right ... Neither of my Bandits corners well at more than 4psi away from the recommendations - at five psi out the handling notciably changes .... I check my tyres every tank full ... I can't imagine trying to handle a bike at less than 20psi in tyres ... (I wonder if koba rides the VFR my GSF650 wasted a while ago ... the VFR couldn't handle the corners ..

Haha! yeah, that must have been me.
