Tire pressure for Interstate

[RCPhil]

Okay, I have read and re-read tire threads for the past year and don't have problems with tire pressure for normal twisty riding. I may ride to Virginia tthis weekend from Pittsburgh and may be on the interstate for a while. Any thoughts on tire pressures for better tire wear on the super slab?

This is what I have found on search but want to know if anyone has anything else to offer specifically for straight interstate riding to help prevent squaring. I am too used to the twisties around here. :-)

"35 Psi front and rear, track
36 Psi front and rear, street
34 Psi front 32 Psi rear, track
32 Psi front 30 Psi rear, twisty road
31 Psi front 29 Psi rear, track
34 Psi front 36 Psi rear, Hwy and or passenger"

I am running Pilot Powers. I just took off the 208zr's yesterday annd got about 5000 miles out of them.

Thanks in advance.

There's nothing you CAN do, IMHO, on highway driving, to prevent squaring. You're only riding on that small, strip of center tread, hence the wear.

I'd run 38 rear, 36 front and avoid hard accellerations, and if applicable, decellerations by downshifting.

Heat and friction wear tires. Reduce heat on highway use by running a higher PSI and reduce friction by not hammering the throttle, or rear braking by downshifting, or with the rear brake itself.

Factory wants 42 rear/36 front, but that makes me a little hinky too.................

Shit can that 35psi track temp. 35 nearly cost me dearly at Barber . 31/30 and all was well .

Dave's numbers will get you there but bring them down once at your destination.

I have no clue where you got those air pressure figures and for what type of load conditions.
For the track, I wouldnt stray too far from 31f30r except if you're running those Pilot Race tires then its something like 28f25r.

IMO, unless you have the bike packed up on the heavy side or riding 2up, I wouldnt go above 35# for two reasons:
1) if you do it's gonna be one bumpy ride, exp joints, etc...
2) I could be wrong here but Im thinking more air will equate to faster wear on that center strip since you're decreasing the amount of contact patch you will be riding on. Id start out with 34/34 as a baseline and go from there.

Have fun!

Yeah, I go those searching but wondered myself where they got them. I had actually set my tires at 34 fr and 38 Rr before asking and will probably go with that. I usually run less in the rear but wondered about heat. I went for a ride today and the bike felt very good at those pressures so I think I will use it tomorrow. I may actually alter my route too and take the back roads through WV instead of all interstate. It will add a little over an hour to the ride though, but it will be more fun. I'll probably drop a bit of prssure if I want to do some real riding in the back roads but I am sure I will be okay at 34/38 as long as I'm not playing real hard. I'm riding to get there tomorrow.

Thanks for the reponses!
