Run flat ride comfort

Hi all

I've just read somewhere that you can substantially improve the comfort of the ride if you move away from run-flat tyres? I've currently got Pirelli P-zero run-flats on mine and it won't be too long until I have to change them, so was wondering whether anyone else has noticed any difference if they've moved to ordinary tyres? I've got a space saver in the boot for any long journeys, so I'm not concerned about being stuck if I get a puncture etc.

Thanks

Shaun
 
Mine didn’t come with runflats in the first place, I didn’t think any did?
 
As above, my car came with a repair kit in the boot, for use in emergencies. Having used some tyre repair stuff in the past, I suspect it's only of use if you get a nail or similar in the tyre. Anything large and the liquid sealer is just going to pour out, so I'm expecting to have to make use of the recovery services if I get a serious puncture at any time.
 
AIUI, it's best not use the repair kit anyway as it'll ruin the tyre - it may otherwise be possible to get the tyre plugged (I've done my previous XKRs a couple of times from self tapping screw insertions - cheapest Jag fix ever!).
 
I have a decade of experience with runflats and same car not on runflats from my old BMW Z4 days and there is no doubt that the ride is much better without.
Difference was night and day and all the comments being raised about spares, inflation kits, etc are well known by raft users
Only one I disagree with is that the run flat tyre is scrapped by using the inflation. Not really true, but you get varios tyre companies who act in different ways. Some refuse to repair runflats at all, outside some limits or if any wall degradation from driving flat and some object to cleaning the ‘gunk’ out. I’ve had all combinations

All said I’ve never had runflats on my F type and didn’t even know they were fitted? You’d need special rims

If it was my comment you're referring to, i wasn't talking about runflats, but ordinary tyres repaired with the sealant kit. I have no experience of using said gunk, just what I've read about it.
 
cj10jeeper - many thanks. That seems to back up what I read as well. I think I'll be putting on "normal" tyres when I need to change.

The same applies to ‘non runflats. Using the inflation kit does not ruin the tyre. Some garages do not like cleaning it out before repair and prefer to sell a new tyre. Much less messy and more profitable.
 
Are you sure you have "run flat" tyres?

The cars are fitted with P-Zero non run flat from factory. These are XL (extra load) tyres but NOT run flat.
From your previously posted pictures I cannot see the tyre markings to check.
 
I'm of the mind that 2 and 2 have been put together to make 5. Although run-flats are known for providing a harsher ride, I suspect whatever ride the OP is getting it's just the nature of the car. The only area where most people seem to agree is that the Pirelli tyres are a bit pants and better handling comes with changing them to, say, Michelin Pilot Sport. It would also seem a very strange thing to have run-flats on a car specced with a spare tyre!
 
Pirelli does make P Zero run-flats, so maybe the new models ...?
They are a lot more expensive though, so doesn't seem a likely option.
