Am moving to Dubai for a couple years and the G will have some 8 month periods alone in the garage, unstarted. I believe I can safely store the car by overinflating the tires by around 10lbs, and putting a battery charger on it. But not sure which battery charger or type is the way to go. Suggestions?
Or would you recommend simply disconnecting the battery and letting it sit there

 

Disconnect the ground and just leave it like that. Don't charge anything while you're not around lol.

Your tires will be fine also. There's no reason why your air would just all leak out

 

put your car on blocks if youre concerned about that

 

I store my G37 for the winter and connect the battery to a CTEK Multi US 3300 Charger. That way it saves me from reprogramming the electronics like Homelink etc... The charger works well.

For my boat I do disconnect the batteries for winter storage.

I never pump up the tires or put the car on blocks and don't have the any problem with tires off round for winter/summer storage up to six months.

 

I have good results with the BATTERY TENDER trickle charger. I got it from Amazon.

 

8 months storage i would take the wheels off.

 

Here's a list I have saved on my PC

Fill the tank
Add Stabil
Disconnect Battery + Put Tender
Raise the car on jacks
Zip in Pocket
de-humidifier
