Tyre Pressure

[Ezikkiel]

Hey guys just a quick question my booklet states that the D675 should be 34 front 36 rear ( PSI ) I recently got some Pilot Road 4's fitted and the garage had put 36 front and 42 rear! I have since ( after a week of riding ) lowerd them back down to 34 - 36 they feel better in some ways but a little slippy or less something cant think of the word i would like to use im almost certain i can hear the tyre making more noise now ( front ) but i did see a guy who rode on slighty lower PSI than the booklet and it gave him a higher contact patch. I am considering going 36 front 38 rear. Can any shed some light onto pro's con's how it all works whats right wrong etc etc ta very much!

I usually run with 36 - front & 41 - rear......which works ok for me...... Guys doing track days normally run lower pressures......but, that is the COLD pressure......the tyres will get hotter on the track, so the actual running pressure will probably be the same as for normal road riding..... running lower pressures for "greater contact patch" is bollox in my mind......

Try different pressures and see which feels best for you.....and your riding style.....

I usually assume that the manufacturer has more than a bit of a clue, and follow their recommendations.

agreed.. but also the tyres makers recommendation should not be automatically ignored. somewhere between the two is about right.. you can work out which works best for you and your riding style with a little experimentation.

On my old GS I use the tyre makers recommendation... mainly because the pressures recommended by BMW date right back to 1993. And I reckon tyres have come a long way since then.. works for me!

My street triple r handbook states 36f/42r I would imagine the D675 would run on the same pressures being or or less the same chassis ?

I run mine on 34f/38r

garages put more pressure in initially so the tyre beads properly.

Yeah but it's a lot more than 42psi try something like 70 upwards!!

Set the pressure at the specified setting if your not happy increase them by 2psi at a time until you are

No more than 42 rear though

Hi guys just put 36 in front and 38 rear feels very nice so might stick with that but front had lost 5 psi since last Tuesday when I last done them

Give the tyre a good check over to make sure it hasn't got a nail or something in it......if there's nothing there, then maybe the valve isn't seated correctly or is faulty.....

No nails and they changed the valves when the done the tyres! bad workmanship?

Keep an eye on the pressure mate......but if it keeps losing that amount over a short period of time you need to get it checked out....

You cant beat a bit of soapy water applied arounf the tyre and valve...then simply look for the bubbles......simples..

A bit of spit works well too......although, licking your tyres is seen as odd behaviour in some parts of the country.....

Listen to manufacturer reccomendations. The side wall will list max pressure. The manufacturer will have taken into account type of bike weight of bike, average weight of rider ect.

Eerrmmm max pressure does not mean riding pressures....I'm sure you understand that right?

I may have not explained properly or I've been miss understood. I mean don't go by max pressure on side of tyre as this is just max safe pressure in general. Listen to manufacturer (of the bike not tyre) as they are the ones that have worked out the pressure for correct contact patch on that particular bike

What has max pressure got to do with it?

And yes, I do know someone that confused "max" and "recommended" and rode his bike for a while with 100psi front and back.

Read my post above where I explain myself better, I was correcting the person that said that tyre manufacturers shouldn't be ignored as it sounded like they were saying to go by side wall pressures.

The question was rhetorical
