I agree, we several days through fall and winter that are nice enough to break it out and go for a drive. Maybe I'll take it to St Boniface in Ephrata :-)

I put the car on a battery tender, fuel 3/4 to full with stabil in fuel ( AND run through the system), tires are sitting on squares of plywood. Car is there November until march or April ( I hate the northeast. want to move and never put a car away again). Come spring I hook up the battery take of my covers turn the key, move the car to my back garage lift, change oil, check fluids, air pressure, etc. and im good to go.....FINGERS CROSSED never an issue. 

Any flat spots in the tires are woked out in a few miles but I've never really had an issue. currently running BFG's comp 2's I think? stock size. 

^^^This....except I usually put 40-42 lbs in. Takes just a couple of minutes to let the air out for a ride. Both my C4s have Continental Extreme Contact tires, they do tend to flatspot a little with continued sitting, but about 10 miles down the road they're good to go.

An old time car guy once told me (and he had 4 from the 40's and 50's) it's not the sitting, but the concrete will suck the life out of tires.  He told me he put big black garbage bags under each tire, rolled them back and forth a bit every couple of months to help with flat spots and his tires lasted twice as long.  Another friend who was a mason agreed, said concrete is nasty stuff even when it's been cured for years.

Thanks for that tip!

Thanks for sharing.

Hello, After attending a Tire Seminar for RVs, the consensus was to not have the tire in constant contact with concrete. Anything between the tire and floor will lengthen tire life. 

Ok, so after doing a lot of research and hearing what other members have said, I settled on a solution. I purchased interlocking foam pads from Harbor Freight.  Covers the whole floor, except under the engine (have a small oil leak). Keeps the tires from having contact with the cement and feels better walking on it. Cost less than $60 and I can still easily take the car out on a nice day :-)

Thank you for the tip on tires. I’ll give this a try.

The HF pads sound like a great solution. That’s a win win, good for the tires, soft to walk on and great for my back when I lay down under to work. And maybe take a nap 😴 

Jack stands.  I’ve seen tire cradles, would have to match tire radius to work well, to help prevent flat spots. Worried about dry cured concrete??? Epoxy your floor. Makes clean up a heck of a lot easier
