Road Attack pressures?

**nallac** · 28th August 2008, 21:38

well my new tyres have finally turned up ex the states.
shit only took 3months..
I'm taking them in to the shop tomorrow to get fitted and want to know
what pressure people have/are run(ing) in them?
I've read somewhere about running them higher than other tyres.

I'm thinking around,
36/38 front?
40/42 rear?
whatya reckon.
oh there on a CB900.

I run mine on about 36-34 and 40. I have Ohlins rear shock though, so not sure if that makes any difference.

2.5 front (36 psi)
2.9 rear (42 psi)

i replaced my road attack rear with another yesterday

the bike is recommended to run 42psi front and rear

haven't checked what the shop inflated it to yet but will check this arvo (i once had a new set of PR2s put on with 24psi front and rear!

)

I notice that everytime I get mine back from the shop that the tyres are fairly under inflated, not sure if that's done on purpose, but I run mine slightly under the recommended pressures because I think it feels too hard when they're on the recommended. I've had a bit of a play about with the pressures, deflate them to around 30-34 and 36-38 and find that it feels like they need more air so have found a happy 'medium' with 34-36 and 40 which feels right to me. Maybe have a play and see what feels right to you? I no expert so not entirely sure what difference a few psi makes... I'm sure someone will tell me shortly.

I'm similar; when I discovered those low pressures on my last bike (RF900) I put them up to 34/38 (I think recommended was 40/42) but found those pressures a bit too hard for my liking and backed them off a bit.

Theoretically softer tyres will grip a bit better (bigger footprint) but wear faster I believe.

I run 30 psi front, 32 rear is that too low???

That does sound low, but you need to check what the bike/tyre manufacturers say. Bike tyres are way different to car pressures. Bike pressures are higher to stop the tyre deforming when leaned over.

My CBR recommended is 36/42 so that's what I run. I can feel immediately if they're down 2psi as the bike just doesn't want to turn in or track the same.

Thanks for the link cajun, didn't know they had such a large/good fitment guide.lucky you converted them bars to psi cause i have no idea what psi=bar

I always check tyre pressure when i get new tyres fitted bike or car
can never trust em mechanics/tyre fitters even tho i've got a couple as mates.

I'll start at 36f 42r and play with pressures from there.

Doesn't lower pressure = more heat and higher pressure = less heat in the tyres? I know from experience that 0 pressure will melt a tyre very quickly.

Honda recommend something like 42 in the rear - I have found this way too high for any comfort and run 38.

The Honda dealer and my local tyre man agree - 36 front 38 rear, if two up add to the rear 40-42. The Hornet is a relatively light bike.

Start with 36 front -38 rear.
