Cheers XBox.....!

I wasn't wearing my specs when I read it so every chance I've not noticed the print.

Jesus H... getting olds a bummer...!!!....

Arn't we all

I ache after crawling around on my knees and back, while doing my zorsts

Time to get a workbench with lift

So, 30F 32R cold.
What would you run at the track considering you'd normally drop about 4-6 PSI out of it?

Same pressure, or drop it?

zaster

Drop it by the said margin.

Chuck

The line is getting closer and closer between sportbike 'street/sport' tires and 'track/race' tires. With pressures already at F30.5 R32, I'd say dropping a bit may be ok, but I wouldn't go as low as F25 R26. It is likely that you'd experience significant flex in the tire sidewall carcass, especially at tighter tracks. At higher speed tracks you'd likely find tires would overheat at very low pressures. I'd start at the recommended street pressures for a lap or 2 then adjust accordingly.

I love how everyone is giving their ultimate pressures. Tire pressure is adjusted according to outside temp., type of road, etc. but mostly the temp. The colder it is, the lower the pressure. Right now in mass. , it's pretty cold, I'd probably go down to 28-28. Lots of highway, probably 30r-31/32f. You should probably have less or the same in the rear. If I remember correctly, pirellis and Michelin are usually the same front and rear, maybe 1 lb. up in the front. Dunlops were always 4 lbs. differance example:30r-34f. But most importantly, you need to run what feels good to you. As for the pressures on the side of the bike, they seem high. The manual is more realistic in my opinion. Good luck.

Riding road, just had a new rear put on. I'm riding cold 30 F and 29 Rear, has a nice feel.

Previously had 31F 30R. So I may go down a little more to see how that reacts.

Hi Xbox,

just had my rear tyre done at protwins uk, due to nail. They recomended 32f 34r which is what I'm running and seems pretty good for the roads. AC

i can only agree.
ran 29F/27R on a hot (90F) day at the track and chewed up the tyres. massive hot tear. handling was crappy. didn't get to correct it properly, as i didn't get the tyres to cool down that day.

last time (75F) with 32f/31r way better wear pattern and much improved grip and handling, as well as high speed corner stability. (non-OEM supercorsa, see related thread)

pirelli at ducati island in indy mentioned their recommended pressure was 2.3 bar/33.35 psi f and r

zvez

for the track? That's higher than the recommended street pressure.
Also, generally, how much of an increase in pressure from cold to hot is considered ok?

It's interesting as here's Pirelli's recommended pressures for the Supercorsa DOT track tires.

that's what the guy's said there - for the panigale.

Just texted mechanic friend who is doing 1199 dealership training class out in Cali. His response for cold street tire pressures are front 33, rear 37.
I had been running lower pressures because of track riding, but he said the tires just won't get nearly as hot with street stresses. I'll try and see.

zvez

This was discussed before, the headstock sticker on my pani lists front tire press to be 33.4 psi cold and rear 37.8 cold!

THe manual on page 231 lists front at 30.46 and rear at 31.9

and further "traveling on very bumpy roads increase tire pressure by 2.9 -4.35 psi to preserve the roundness of the front wheel"

any thoughts on this big discrepancy?

1198freak

I keep the 1199 at 30psi rear and 31psi front cold temps for street, works great if you ride aggressively. If I take the 1199 to the track I will run 28 rear and 30 front.

27F 26 Rear Thats me But i love it.

Laurentinium

32/32 cold works for me...shouldn't go over 34 hot

mrez1

I've always ran 32 F and 37 R. Seams to handle a lot better

nomnom37

That sound a little too high. It may feel good but it's like an over inflated ball. There's no give. The air in the tire also help the ride of the bike so you might want to take it down to somewhere in the mid 30s. And have fun.

WAfatboy

Sorry but I'd always understood that if the ambient temperature was high then you'd run lower pressures because the tires would quickly gain heat and their working pressure would rise.

We get 40c regularly and if I have the cold tire at 2.1/2.2 as per the manual when the tires are cold then surely it will be running much higher once the tires heat up and the air in the tire expands?

Anyone?
