Hybrid Tyre Pressures

[lcmarky]

Folks with Hybrids..

What tyre pressures are you running?

My tyres are Conti Race Attack Soft Front & Medium Rear.  Sizes are 120/17 17" Front & 160/60 17" Rear.

I'm thinking 24 PSI Front & 26 PSI Rear.

Who's experience with trying different pressures?

Cheers

I just stick to the recommended pressure quoted by the manufacturer.

I do the same also on track days then look at the tyre and lower or higher the pressure. The funny thing is I'm not 100% sure if what I do is the correct action!

Think I ran 28/32

I thought the idea on a track day was to lower them a bit

Not to increase the contact patch but to compensate for the higher running temp causing more expansion and raising the temp too much

Yeah look at the tyre wear and go up or down on pressure, With the emphasis of keeping heat in the tyre or not too much depending on your riding style and conditions.

Hi LCMarky

Sorry I havent used the "Race Attack"

 However I have used the "Conti Classic Attack" on my LC250

the side wall is very stiff, not much flex but they are a great tyre, loads of grip.

I got them so I could go testing them to the best pressure for feeling especially in the front I ended up with Front 24 Rear 27 

As for compound not too sure as I think the road tyre has only one compound (but could be wrong) as had to get the same tyres as we were using in the Pro-Am races

We used these tyres in all the races, 2015 we couldnt adjust the pressures hence why half the field crashed in the very wet conditions

I found out later that presures were Front 36 Rear 38 ( know wonder most of us crashed)!

Cadwell 2017 we were allowed to adjust presures + or - 4 PSI

However as there were a few mechanics missing, so I just used my own pressures 24 & 27 You know it makes sence !
I wasn’t the only one who changed the tyre pressures that weekend

Sorry I dont know the different between Classic Attack and Race Attack (ask Conti think the guy was called Grahan Marchant
But I think its worth your while testing just to get a good feeling and as mentioned above look at tyre wear

Hope that helps

Best regards
Johnny C.

Thanks Johnny & I'm not surprised there were crashes with 36 & 38.  I ran these initially @ 30psi just as I would typically on track, but felt too hard hence my question here.

Sounds like I'm close with 24 & 26 and I plan a ride out today to give it a go.  I've also backed off my Hagon shock pre-load & I know you should only change one thing at a time, but it was way too stiff.

Appreciate the guidance - many thanks!
