387 mile trip in my Touring

[openball]

I will be taking a 387 mile trip in my Touring tomorrow, both ways.
I have a backup stop on my return but hopefully I don't need it.
I pumped my tires to 46psi 153 miles ago and have averaged at 4.4/kw driving at below 70mph so keeping fingers crossed.
I will post my stats when I get back, em... if I do get back.

Are you on 19s?!

Are you on 19s?!

Yes 19s

 

[hydbob]

Yes 19s

19s are supposed to be 49 psi

 

[openball]

Wow! I received them at 45 but the cold weather dropped them to 42.
It should be in the 70s tomorrow so I'll fill them up to 49 before I take off.
Thanks!

19s are supposed to be 49 psi

Max 53 when hot.

All USA cars have a sticker on the driver's door jamb that shows recommended tire pressure.

*for the OEM wheels and tires the car was originally delivered with.

I like the way my 19’s ride and handle when they are in the 47-48 psi range. Seems to improve impact harshness noticeably. Lots of bad roads here in the upper Midwest. The loss in efficiency is negligible to <5%. The issue of weight on the tire only matters if you load up the vehicle and for me it is only myself and my wife. When I do a road trip I will keep it to 48-49.

I bought a very nice digital tire pressure gauge that reads to 0.1 psi increments. I can notice ride quality differences down to about a half-psi up or down.

Try charging 2 times 15 minutes at a time 25% to 70%. You might reach your destination with over 50%

GPS recommends I charge on the way back.

I started off well at 65mph and no AC, after I turned on the AC and increased cruise to 70 it dropped to 4.4

 

[HariK]

Speed is a big negative over 70mph.

Please can you send the link to the digital pump. I come close with the lucid included pump but not perfect

I'm very happy with the range. I would have made it back without charging but it wasn't worth the risk of running the battery out. After I charged I switched to sprint and drove like the car should be driven.
