tire pressures

[jerry]

I put 31 in front of S4 and 36 in rear I know the old owners book says 31 rear but i think its out of date ,

My Z900 has 32 front and 38 rear Kawasaki reccommend 32-34 front and up to 42 rear ,, seems excessive to me especially in a hot climate like Thailand


On M750 and 750ss in Uk its 31 front and 36 back


whats do you guys do ??

2004 Monster 1000Sie - 35 rear, 33 front - running on Avons whose website says use the pressures in the manufacturer's handbook.

2002 Monster 7501e Dark - 36 front, 42 rear - running on Bridgestones whose website quotes 36/42 (in practice I usually run the rear at 40). Previously, I ran Michelins and used their website pressures which were per the handbook

Not sure what the question is here Jerry if it's tyre brand soecific but for Pirelli Corse I akways run 5 psi more in the rear, that works for me but I don't know about other brands so much, but I would go with that as a starting point. See what the rear is doing and go 5psi leds in the front.

Darren I normally do what you suggest , seems to work well for me ,,,But S4 manual says 31 in rear which is way too low in my opinion I dont know what Ducati were thinking back then in 2001

That seems a little low, probablyva typo. Is that in the owners manual. I dont think I have one for the S4.

Here's interesting.

My M900ie owners manual gives the figures in Bar, kg/sq cm and lbs/sq cm.

Converting those with with online calculators, I get;

Front, 2.1bar = 30.4psi
Rear, 2.2 bar = 31.9psi

Front 2.3kg/sq cm = 32.7psi
Rear 2.4kg/sq cm = 34.1psi

Front lbs/sq cm = 32.7psi
Rear lbs/sq cm = 34.1psi

A previous owner has written 33/36 on the tyre pressure page, so has obviously come to his/her own conclusion.

I've always used 32/36 and found it very sensitive to those pressures.
Always take the tyre fitters advice though if they are prepared to give it.

I seem to recall reading 32/35 in the manuals for both my Ducatis. I always add a pound to any tyre pressures (more is more right?) so use 33/36 and not had any problems in doing so.

For what it's worth about 25 ish years ago I spoke to an engineer at Avon tyres who told me to put 40 psi in any rear tyre of a modern bike with radials.I had a newish Thundercat at that time.

Interestingly i used to run 26 front and 22 rear (cold) in my race bikes. Obviously completely different application but quite a big difference eh?

Funny thing , tyre pressures. I run both my bikes at 36 to 38 front and rear. The Monster is on Maxxis and the Tuono Pirelli. Very different tyre construction but feel good to me at that.

My Z900 owners manual says 36 front and 42 rear but after 10 miles in Thailand front is 38psi and rear can be up to 46psi. And at that pressure the front is too hard and the rear has no grip. So I put in cold 31 ront and 37 rear it's much better
