I don't want to jack the car up. Thick carpet? Will be sitting in the garage for a year! Volks are coming off and the OEM's will be put on.

 

I inflate the tires to full pressure- 50 psi and then drive onto 4 pieces of blueboard insulation (2 " thickness, I believe) when I store for the winter.

This has worked very well.

 

I have not stored my Z for for that length of time(might suffer from withdrawal symptoms).....I understand that the radial design in current tires has eliminated the possibility of "flat spotting".......even so, I use carpet squares, and that has worked very nicely.
I also use the above mentioned tire inflation practice too.....

cheers......

 

Just give me the keys and I'll take it to Pueblo Motorsports Park for a few laps each month. That'll make sure those tires stay in proper working condition!

 

 

how long does it take for tires to flat spot? ive had the z sitting for 2 weeks already. will flat spotting work its way out? or are the tires done? i dont know anything about this.

 

Same as mentioned earlier...I heard that radials eliminate the problem of flat spotting. If you want to fill the tires up to a max psi, that wouldn't hurt either.

 

You also have to worry about the rims going out of round. I had a car sit for about 18 months and the rims went out by 1/2". I'd suggest some really sturdy stands. Not what you wanted, but it is the best for the car. Besides, the springs could be affected as well.
