I ran the Tail of the Dragon years ago on my Buell Cyclone that was great fun. I would love to make it back up there with Little Missy. You enjoy yourself and be sure to post some pictures. :thumbs:Sunny Ragtop said:I sent a PM to another forum SKY owner just this AM for an Answer. I'm going to the NC mts Thursday to run the DRAGON (Hwy 129, with 218 curves in 11 miles) love it on my motorcycle, looking for fun also in the car.
The SKY manual says the posted "door sticker" 29PSI is MINIMUM air pressure. I don't have my SKY at work today but it seems like the tires had 40psi written on the side..or at least a lot higher max then the door. I'm running 31-32psi....WHAT SHOULD I RUN?
i know doesn't sound right cuz been 32 forever on everything else but 32 is a horrible ride and steering changes sooooooooo much !!! back to 29 and stayin there !!! book says 29??? drive the 29 psi - unbelieveable difference !! BIG BIG differenceJFig said:I had checked my tire pressure this weekend and discovered different tire pressure on all my tires.
It ranged from 32 to 39.
I guess 32 is a happy medium.
Anyone have input on this subject?
Ooooh I'm jealous...did the Dragon in 2004 on my Harley...what a rush!!! :thumbs: By the way...you're off by 100 curves...it's actually 318 curves in 11 miles. Have fun and be careful out there...watch out for those semi's that take up both lanes.Sunny Ragtop said:I'm going to the NC mts Thursday to run the DRAGON (Hwy 129, with 218 curves in 11 miles) love it on my motorcycle, looking for fun also in the car.
Thanks ALL....My dealer did not know for sure either since the manual CLEARLY states 29psi is MINIMUM and tires have 44MAX.Way2Fast said:Run the tires at 29 psi cold and you will be replacing them in 20K miles or less. Keep them at 35 psi minimum and they will go for thousands more. Your fuel milage will also increase. The car will ride firmer and not be "mushy" and soft. The door sticker recommending 29 psi is for those who purchased a Sky but want it to ride more like a Caddy than a sports car.
29 PSI won't cause premature tire wear to the extent that replacement would be required at 29K. That's ridiculous. Inflate them too high (35 PSI is too high)Run the tires at 29 psi cold and you will be replacing them in 20K miles or less. Keep them at 35 psi minimum and they will go for thousands more.

Well, I'm not going to get into a big PM about credentials. Suffice to say I know my way around a tire.1st Gear said:Goodyear Eagle Tires are high performance, low profile. They require more air than standard profile tires.
On the sidewall max. pressure rating is 44 psi.
I run at 36 psi and use valve stem pressure gages.
The car still has a smooth ride and handling respone is better.
I bought the gages at O'riellys Auto Parts, pack of 4 / $9.99.
cheap investment, relacement tires are $235.00 each
i can't talk tire talk and you said it soooooo good - i knew it just couldn't express itKappaMan said:Well, I'm not going to get into a big PM about credentials. Suffice to say I know my way around a tire.
Having said that, I do disagree. The ride is harsher at 36 PSI. The steering is definitely light and uncomfortable at 36 PSI. The amount of grip available on bumpy corners is SIGNIFICANTLY reduced.
Sidewall max pressures have nothing to do with appropriate running pressures. The P245/45 R18 is low profile - but not REALLY that low. It is the SAME sidewall height as a P205/55R16 tire. NO KIDDING! I would hardly classify that as low profile (yes the aspect ratio is an indicator, but that is only half of the story).
A P245/40 R18? That's getting to be low profile. A P245/35 R18? Now THAT'S low profile.
The other thing that factors into this is the relationship of the load to the max load of the tire. This tire is a 96 load rating. The SKY should have a tire closer to 86 or 88 load rating. This means the tire is OVERSIZED for the application.
When a tire is oversized, you need to use lower pressure, or you sub-optimize the footprint (and the application will 'act' like it is overinflated - generally light steering, bouncy ride, momentary loss of grip on transient-bumpy roads, and mismatched radial rate for the shocks and springs).
Bottom line - you'll be happier with 29 psi. The steering will have better "weight", and it will handle better over a wider range of roads.
But go ahead and try 44 psi - and have a taste of what run-flat tires feel like.
I encourage you folks - don't just take my word or 1st gear's word for it - try it yourself!
YOU EVEN HAVE THE INFLATOR IN YOUR TRUNK :lol:
You could easily pull it out, pump up your tires to 44 psi, then drive it and inch them down to see what it feels like. Try going down to 25 psi (tho I don't recommend you stay there - but experimenting with it shows you what it feels like). You can always use your inflator (which is always with you in your trunk :lol: ) to pump them back up.
