You know, this is exactly why I am involved with forums, and particularly this one.
The breadth and depth of knowledge amongst the membership never ceases to amaze me. I explain this to those looking for a ZR-1 or ones who just bought one. While I can tune a 427 tri power by ear, I cannot possibly know everything about Corvettes. This tire flat spotting problem has plagued me for years because I do not drive them enough, even though I might like to do so. Nelson and George, Brilliant idea!!!! I will air both cars up this weekend, might as well try it on the Riviera and others as well!! Don't think I can salvage the current sets of tires, although it is worth a try. I took the ZR-1 to 100 plus more quite a bit on the turnpike returning from Carlisle hoping they would heat up and finally return to round. Improvement, but still see and feel it, both front and rear. Also, that is why I ditched a set of sumitomos before the Nittos, that had under 1000 miles on them. I likely will go back to Good Year GS- D3's on both Vettes. They seem to be ok on low mile cars here at the dealership, so maybe that will also be the final answer. Thanks again !!! Marty |

Just another thought.. Those cupped ramps run like $230+ for a set. I'm thinking anyone with a jigsaw and a pattern could cut out and stack enough layers of plywood (glued and screwed) together to make some for a tiny fraction of that $200+ cost (which is ridiculous)!
I've read where putting the car up on jack stands to lift the tires from the goround...is an option. Never tired it because - I usually drive them a few miles if the roads are clear, or at least re-position them before parking again. I've been running the Nittos on both Zs - never had an issue, but too I limit them to 4 driving seasons, regardless of remaining tread, 5 MAX. (I'll try the air pressure method this winter too - never thought of that!)

My cars were usually stored for three to four months, first on a garage floor then on a lift. With both the cheaper Sumitomos and with the Michelins, I routinely used higher than normal pressures during storage with a note taped on the steering wheel to remind me to return the pressures to normal in the Spring. On the advice of a guy who services and stores a lot of very high end cars, I was originally setting the pressures at 60 psi which worked fine to lessen flat spotting for many years. But I eventually got a slow leak on one of the Michelins on the 95 that turned out to be a bad valve. When getting it repaired I was told (at Costco where they replaced it for free) that valves are officially only warranted to 40 psi. Still, that was the only time I had had a problem, so since then I have used about 50 psi with no issues. Any residual flat spotting usually went away with an hour of driving. --Bob

I have had great success with parking on rubber stable mats. Any farm supply store sells rubber stable mats. Just cut them into approx 18"x 24" rectangles. Sent from my iPad using ZR-1 Net Registry |

We always set it on 2 inch styrofoam while doing the increased air pressure when it goes away for the winter

I have been parking on carpet squares for years on all of my cars. Never a flat spot. The other benefit the tires seem to hold air all winter.
Once the salt flies my Z, 62 BelAir, and my mint 93 Olds Dustbuster Van retreat to an unheated, but dry, mouse free garage through the cold Illinois winters. I press all my cars up to 35 psi cold. Hook up the battery tender, start them once a month, and just watch them sleep. First drive in the Spring no flat spots. You can get carpet squares that are seconds in most Flooring stores for next to nothing. Sent from my XT1254 using ZR-1 Net Registry mobile app Last edited by mcich7781; 10-01-2017 at 09:05 PM.
