maxi-glasgow Posted November 13, 2012 Share Posted November 13, 2012 I have a mate who can get hold of Bridgestone 050s in the correct sizes for me but they are run flat models. Are these usable on the 370? Havent a clue? But need to ask as i have been offered them at £100 a corner.... Quote Link to comment Share on other sites More sharing options...
JetSet Posted November 13, 2012 Share Posted November 13, 2012 (edited) I think you need a Tyre Pressure Monitoring System (or a warning light) to get run flats through the M.O.T . Could be wrong though. Pete Edited November 13, 2012 by JetSet Quote Link to comment Share on other sites More sharing options...
The Bounty Bar Kid Posted November 13, 2012 Share Posted November 13, 2012 I believe Pete is right, but more importantly... Are you being serious? You've bought a 370z and you're now gonna get some run flats as they have been offered to you cheap. IMO run flats will ruin the handling and performance of the car. They can't compete with normal tyres. The sidewalls are made so tough that it just makes cars horrible to drive hard. They are for lazy people. TBH if you don't drive your car hard, then go for it. But if you do enjoy driving her with some vigour every now and then, you're gonna be so so dissappointed!!! Quote Link to comment Share on other sites More sharing options...
Ricey Posted November 13, 2012 Share Posted November 13, 2012 Runflats are the sperm of satan cooked for 8 hours and added to a tyre mould. They will annihilate any enjoyment of your car I promise. Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted November 13, 2012 Share Posted November 13, 2012 Runflats are OEM on many performance cars including the Nissan R35 GT-R. Providing they are a premium brand then I would be inclined to give them a try, however be prepared to have your ride compromised as the guys have said above. DO IT, and let us know how it goes.

Ekona Posted November 13, 2012 Share Posted November 13, 2012 There's a difference between running runflats on a car that has had its chassis and suspension tuned for them, and running them on a car that was designed for normal pneus. I wouldn't touch them. Not even at £100 a corner. 1 Quote Link to comment Share on other sites More sharing options...
maxi-glasgow Posted November 13, 2012 Author Share Posted November 13, 2012 Cheers for the replies, I had a funny feeling it would have an impact on ride. Bargain of the century though, think I may still buy them then punt them on eBay Quote Link to comment Share on other sites More sharing options...
rtbiscuit Posted November 13, 2012 Share Posted November 13, 2012 (edited) i'd leave the run flats alone lots of people who have cars with runflats, the first thing they do is take them off and put decent tyres on.

Dave-350 Posted November 13, 2012 Share Posted November 13, 2012 Sorry, I didnt read any of the other replies as all I have to say is WHY? Run flats are terrible and should not be put on a car of this sort! Just carry some tyre weld for that unfortunate moment when it does go flat! Or even better, a spare wheel Quote Link to comment Share on other sites More sharing options...

As long as there's some kind of low pressure warning light or gauge then you'll be O.K. Presumably the monitors are inside the wheels? I believe that all new cars sold from 2012 onwards in The E.U are fitted with TPMS by law. Pete Edited November 13, 2012 by JetSet Quote Link to comment Share on other sites More sharing options...
Ricey Posted November 13, 2012 Share Posted November 13, 2012 Do a test first and see if you can cope with the ride quality. Get a pneumatic jackhammer and insert the tip into you anus. Turn it on and see how it feels. 3 Quote Link to comment Share on other sites More sharing options...

rogerxp Posted November 14, 2012 Share Posted November 14, 2012 Basically +1 to comments above but, more seriously, you can't put a RFT onto an alloy wheel which was made to hold a non-RFT, but you can put a non-RFT onto an alloy made to hold a RFT. It's something to do with a 'lip' on the alloy that holds the RFT in place will also keep a non-RFT secure whereas if that lip wasn't there (like on a non-RFT style alloy) then there's nothing to hold a RFT in place so dangerous. At least this was always the explanation I understood. If you want cheaper tyres then go with something like Falken - I've had these before and have been really pleased with them.

rabbitstew Posted November 14, 2012 Share Posted November 14, 2012 There's a difference between running runflats on a car that has had its chassis and suspension tuned for them, and running them on a car that was designed for normal pneus. I wouldn't touch them. Not even at £100 a corner. +1.... My 123d comes with run flats as standard and the whole chasis / suspension as been designed to work best with them.

Has the Zed gone Stew or are you a multicar owner? lol!!! yeah its certainly a "firm" ride, but I find my 123d seems to actually handle better than my zed did. I certainly feel a lot more confident in it. Yep, the zed`s gone mate. It was killing me in running costs / depreciation, so I part ex`d it for a 6 month old 123d M-Sport Coupe. Whilst its no zed its still good fun. 0-60 in 6.5 seconds, over 200bhp and 300lb/ft torque (which is the same torque as an e92 M3) as standard and you can remap it up to 270bhp and 400lb/ft. Im getting nearly 50mpg out of it, so thats twice the mpg I was getting out of the zed! Quote Link to comment Share on other sites More sharing options...
rogerxp Posted November 17, 2012 Share Posted November 17, 2012 Good choice, I keep checking them out, but the new M135i would be my first choice if getting that sized car, it's an astonishing blend of pace (5.0 - 0-60), price (under £30k in basic clothes) and efficiency (can get decent mpg but obviously goes tits-up if you nail it!). Great deals to be had on one too - I was offered one with basic essential spec (nav, heater seats, etc) for £400p/m with £5k down which is about the equity in my car. That said, Im trying to keep costs down, which rules our the M-lite hence the checking out the 123d (and 330d). Enjoy your 1er, they are belting cars.

AMT Posted November 18, 2012 Share Posted November 18, 2012 I don't have to read too much into this thread, as my friend had them on his beemer, to tell you... do NOT get run flats. So noisey, uncomfortable and i'm not sure how a Zed would react to such a thing. Quote Link to comment Share on other sites More sharing options...
Jack Carter Posted February 22, 2014 Share Posted February 22, 2014 Can't comment about the 370z really, as I only bought mine yesterday ! I did previously own a BMW Z4 though that had runflats and it was as crashy as F*** - Hit a pot hole and it felt like I'd pressed the ejector seat button. I dropped the run flats at the first opportunity (flogged them on the bay) and got a set or Falken FK452's. The result was unbelievable. Totally transformed the ride. Grip was massively improved too especially from cold. Did exactly the same on my current 5 series. Again - transformed the ride when I switched to convention Hankook tyres. My new 370Z has runflats fitted at the moment ( I pick the car up next week) but they will also be dropped at the very first opportunity for either a set of Falkens or a set of Hankooks.

Cake Posted February 27, 2014 Share Posted February 27, 2014 Also if you have runflats and get a puncture you won't know about it, continue driving with building heat from the additional friction causing it to explode. You have to check them regularly to ensure thy haven't one down. Also as stated earlier the alloys don't have the additional lip and more prone to deflating...
