Tyre Pressures - Road?

[krhall]

After a couple of trackdays recently where I have let the tyres on the CBR down from the manufacturers suggested 36 front 42 rear, to 32 front and rear.

I have not put them back up from the last one however and am wondering what the pressures really should be, especially with winter approaching fast.

Thanks,
Kev

RTFM ;)

Or check with your tyre supplier.

BTW - did Honda suggest 42 rear?

Any reason why you wouldnt stick with manufacturers figures? Occasionally you get a different set of pressures recommended by a tyre manufacturer in which case I would follow their advice but otherwise stick with standard pressures.

I always found the recommended pressures best on my CBR. Dropped them by 2 - 4 psi and it just felt squirrelly. Can't get the heat in them on the road to get the pressures up. Always felt most confident at 36F - 42R

Honda 36F 42R :thumright:

Holdup what honda dealer do you work at?

Tend to ride with mine 2psi down on factory recomendation..34f/40r,bike just feels a bit more planted on the road but each to thier own i guess.

it is the tyre manufacturers recommendations you should follow; not the bike manufacturers

[rictus01]

Depends, what tyres you have, what you like and what you're doing with the bike, change mine as and when I deem in necessary :smt102 it's another of those; if you can't feel which is best stick to what is recommended.

Cheers Mark.

Bike recommended feels a bit twitchy at times, 32 & 32 feels great on track but not so great on the A2 on my commute. I have put them back this morning but might try SV-Robo's idea of just down a couple.

I am just concerned about winter commuting on the CBR again, although if I'm honest and could find a supermoto for £1k then that would be very tempting.

Contact the tyre manufacturer/importer and ask them, don't listen to Honda as despite what they think they are not always correct. Every tyre and bike is different, tyre manufactures spend a fortune testing tyres to find the correct pressures and suitability.

The only pressures I could find on the Bridgestone site was for race tyres.

Mine are 015 front and 021 rear, I think.

I run 36f 42r on my 600rr.

That is on BT021, they seem to hold the road alright at that.

Just don't do what one person on here did and just read off the pressure on the side wall - SV running 42psi rear - oops, slippery as hell you say ;-)

It didn't come up with any options for me when I did it. Looks like bridgestone and Honda agree. Sorted.

I was thinking of having my next service done there, although I think I might be out of warranty, in which case I might try and DIY it.

Kevin when you say twitchy do you mean the bike turns in nice and sharply? I've just got rid of my 014's on the Kwak as they were a bit too sporty. Mixed tyres will probably also affect the feel of the bike.
