Mixed tyres.
Hi guys, any useful comments welcome. I am running bridgestone runflats at the moment and thinking of changing to goodyear runflats on the front and goodyear non runflats on the rear. I have chosen these tyres for good mpg, quiet running and good cornering. Runflats on the front will give me safer handling if I have a puncture on the front. Rear runflats are noisier and less eco friendly, so I thought standard tyres on the rear. I have a 16in. spacesaver which I know will not fit on the fronts but I am hoping it might fit the rears if the callipers are smaller than the fronts. What do you think? My driving style is evident by having approx. 6mm. front and rear after 18000 miles.

Apparently it is not recommended to run RFT on the front and standard tyres on the back.
You are okay to run RFT on rear and normal on the front however |

Im thinking of gettin rid of my runflats alltogether, ok i can drive 50 miles at 50 mph but then have to pay probably £200 for a bridgestone potenza at the nearest garage (if on a journey) when i can source them down my local worn place for £80 with 6-7mm tread, as where normal tyres would cost alot less and not be such a harsh ride in the back aswel

To the OP: With regards to having rft on the front, so that you have "safer handling" in case of a puncture?!!!!....WTF?... Sorry mate....but in case of a puncture on rft, the handling would never be "safer" or "better"!!!!....Yes, it will allow you to drive the car for xxx miles at no more than xx mph ( can't remember the exact speed limit you're meant to drive with a punctured rft). I had a puncture on the rear rft and even driving slowly, the back came out at a roundabout!!! and I think that, I even had traction control on that day...which is quite unusual... I wouldn't mix tyres IMO. Not saying that you face a certain death if you do....but, it will cause lots of issues with insurance and handling dynamics of the car ...not worth the hassle IMO. |

[QUOTE=zltm089;15284540]Sorry, just saw this bit...
18000 miles!!!!!!!!!!!!! :sl ap: Whats with all the sighs and slaps etc because I have done 18k on my tyres? It would take less thought to scrub them away at 8k, anyone can do that even with 320d. Your posts seem more about derision than helpfullness. |

Very bad idea. DO NOT MIX run flats with non run flats. I nearly killed myself. They work completely different. The car will swerve all over the road.

I think the OP was just trolling and he seems to drive extremely slow anyway! So no chance of him skidding at 20mph!

OP, it's not allowed to mix rft and non rft on the same car, characteristics are too different.
Againt tyre manufacturers guidance. Insurers might not be happy either if you have a bump.. |

plus it will handle horribly, tyres is the last thing you need to skimp on.
always amazes me how much money people spend on suspension and brakes then complain about spending money on tyres, the part that makes it all work. |

I wouldn't risk for biscuit. RFT and NON-RFT have completely different design and rubber. So you either do the full set as RFT or full set of non RFT.
Reading around on here non-rft is the best decision some folks have ever made but I think you need to declare this to your insurer. I am running Michellin Pilot Sport ZP all around at the moment and I think it is quite possible the best RFT that has ever been made. |

I had 18" bridgestone run flats. My car handled perfect. It felt like it was sucking onto the road. The suspension is also designed to work with run flats. Not so happy with the non run flats. The price of the run flats is the problem.

Anyway, looks like you're in South Africa...don't think you get much rain there!....no wonder your bridgestone were sucking onto the road and with the warm weather, you won't really notice how bad and over priced the bridgestones are. Have you tried using non runflats with the correct tyre pressure? |

Lol this thread is funny. Why try and mix tyres? To get some magic combo?
Fuck the RFTs and put some quality non RFTs on, like PSS. If you're still not happy then there are further ways to improve,,, |
