Default Need Help ASAP.

Need help. I'm new to runflats, I understand that the key to runflat tires at zero pressure is the sidewall and the bead that creates a seal with the rim. Is there any risk at compromising the runflat tire if its removed from one rim and placed on another? Can they just be swapped between rims without degrading it self supporting ability? I'm curious if its worth swapping run flats from one rim to another or just going with a new never mounted set of 4? I need to move on this quickly, any help is appreciated.
Is SmarTire the only pressure management system out there? Whats the scoop with the stem caps that give a pressure warning?

I'm sure that after it's removed from one rim to put on another then it isn't as good but I'm just talking outta my arse right now.

Why would you want to run runflats??? They're heavier.

Anyhoo...hope you find the answers you seek.

My area has lousy shoulders for the roads, just trying to avoid changing flats in bad weather. They would be runflat winters, plan B are the Falken Ziex ZE-512's, plan C Michelin Alpin PA2's. I have to decide soon, temps are dropping - not good news for my RE070's.

Runflats usually need specific rims and mounting to work properly....maybe Luke will chime in here in the am and give us the straight smack on the run flat thing.

Do you need snow tires or AS tires for your area, you don't list your location???

The 512's are just OK for AS tires....there are MUCH better ones available, now...the Proxes 4's and the PZero Nero M&S.....and dedicated snow tires if you need them in your area are always a better bet than AS tires.

I'm fascinated about the concept but maybe the runflats are more of a PIA then I need. For non-runflat winters I've been looking at the PA2's, for all season the top two were Falken ZE-512's and Pzero Nero M+S. I spoke with a friend of mine tonight that has the Pzero Nero M+S and said they are a good non-summer tire. He has them on his M3 and just wants to get something different for the summer and dry action. What I'm concerned about with Winter vs. AS is temperature can vary dramatically, snow one day then 60 a few days later. I don't want to wear down the tires when we have warm dry days, but for the occasional snow I need to be safe. I won't be doing anything insane in bad weather, just want to get home-work-home safely. We don't usually get a lot of snow, more slushy mess and rain then anything. Hmmm. Dunno.

The Pirelli's would be just the ticket for you....much higher performance all around than the 512's and they wear pretty well too.

Another night owl, on late at night. Thanks. I plan on deciding today and getting going. We've been fortunate with warm weather, that won't last long. A friend of mine has the Pzero's and like them a lot also, except for Summer he wants to go back to Summer dedicated and run the Pzero's the rest of the time.

you can re-mount Runflat tires with no issues (other than the effort required) .... and you do not need special wheels for runflat tires ..... the Valve stem cap monitoring is a waste of money because they are not very accurate or reliable

I have used the ZE 512's and they work fine in the snow, even on a torquey FWD. Had them in 8" a couple times and never felt out of control or affraid of sliding off the road. Plus they are half the price of the PZ M+S and will probably last longer.

Thanks Luke....
I read something to the effect, somewhere, that a particular vehicle had/has a special rim that needed special treatement for it's runflat tires....

there is one system called PAX that uses a special wheel but the rest of the runflat application wheels are nothing special ....
