Tyre Pressures (road)

[JDG#92]

Afternoon everyone,

Was just curious as to what people were running PSI wise?

With the lovely bank holiday weekend (UK) I decided to head out on the bike, done the usual pre ride checks and saw the tyers were a tad low so pumped them up.

Currently running a Pirelli Diablo Supercorsa SP 120/70 on the front (35psi) and a Michelin Pilot Road 4 rear 180/55 (38psi)

Curious to see what others are using I know it's down to personal preference but be good to know and maybe experiment different pressures.

Have fun and stay safe, keep it rubber side down

I personally run 36psi rear and 34psi front (which I think are the manual recommendations too) on Michelin Pilot Power 2CT's. I ran the same pressures on the stock Supercorsas, but I ride year-round and those Supercorsas are horrible if the road is cold or wet or you have to stop (ever) and they cool off. If you can manage to keep them in the optimal temperature then they're great, but I've found that the Pilot Power 2CTs are much more confidence inspiring in a wider range of conditions (at least for me).

  I agree with you on the Pirelli tyres fantastic when hot, (used them on the tracks around the UK with tyre warmers and amazing) but hence the Michelin Pilot Road 4 for the rear, had a puncture at 1,000 miles on the rear Pirelli and changed then, will change the front once it's reached it's end of life.

Been using the Michelins PR4’s on the 675 Daytona and find the water displacement much more comfortable and being the UK can never tell if the suns going to stay out 

Might give the Pilot Power 2CT’s next time for comparison 👍

Oh yeah, the 2CTs have incredible water displacement as well (probably similar to the Road 4s, just a little sportier with the tread pattern). It's almost tropical here in the spring and summer where I live, so good wet tires are a must. I've ridden the 2CTs in a tropical storm with sideways rain so hard that people in cars were pulling over. The 2CTs didn't skip a beat. Now, I wasn't locking down the front brakes or dragging my knee, but I never once felt like I was going to slide, no matter how much standing water was in the road. They even feel good in the winter when I've ridden in sub-zero temps (or as good as one can feel on a bike in sub-zero temps).

Also, so sad about that nail in your new-ish rear tire. I had that happen several times (once the tire was less that a week old) and it's always maddening. New tires are nail magnets. I don't think I've ever gotten a nail in a tire I was about to change :/

Hi all, Firstly regarding tyre pressures, so far I have stuck to the standard 36 rear 34 front, and not tried anything else, this is road use only.

I am just about to change the Super Corsa SP tyres, as supplied on the bike from the factory to Diablo Rosso VI's to be a better all round road tyre for mixed (UK) conditions.

So a quick question, what size is the Rear wheel spindle nut of the Moto2, I have a 27mm socket but it seems a little loose, but I do not have a 26mm socket to try, any one know is it 26 or 27mm,

I use a 27mm on mine, and I just measured the nut itself with some calipers and it is indeed 27mm. Someone else on here can probably verify this with a shop manual or the like, but 27mm is what has worked for me.

I can also confirm mine fits a 27 a tiny bit loose but I would be happy to use it. UK bought model as well.

Do let us know how you get on with the Diablo Rosso VI's use to swear by the Pirelli’s but something changed after 2010. And although I've used them on track I changed in 2018-19 to continentals and tbh I think they are just as good but they had a hard life on track.

So, I actually just remembered that the last couple of times I actually used a 1 1/16" socket instead of 27mm and the goofy standard socket actually fits better than the 27mm with no wiggle. Go figure...

Thank you for the replies on the Rear Spindle Nut Socket size

Once I get the Diablo Rosso VI's on the bike I will give some feed back (pun intended) after a few miles.

Initially with them in the house as delivered from Two Tyres ( www.twotyres.co.uk ) who were very competitive, helpful, had them in stock and have a very good web site if you like comparing tyres  they are very soft and seem grippy and are newly produced by the data codes, so I hope they will be good from cold and on UK roads in varied weather.

Just picked up another puncture on the Pirelli Super corsas. Great tyres in the warm conditions but spin up too much during cold wet weather.
Used to run Michelin 2CTs for years on my D675R before swapping to Metzler M7rr.
I can say the Meztler give great confidence in the wet.
Picking up a new set of M9RR's Saturday, which I hear are even better.
Regarding psi I check once a week, 34psi front/ 36psi rear.
