Would you do this with your tires?

[Jeff_Seymour]

I have run flat tires but the rear 2 tires need to be replaced (the front tires are still fine). I want to switch to non run-flats because of what I have read on this board about it being a softer ride. Is it safe to have to non-run flats on the back and run flats on the front. Will a tire store even install them. One company asked me if I had a spare tire when I went there to check on non run flat tires and I lied and told him yes it's at home. Eventually I will get the front ones changed top normal tires. It's a bad economy right now and I don't have a lot of money. Which I checked out tirerack and discount tires for best prices. I was thinking of getting the falkin452 or Goodyear eagle f1 all season.

Cant see a problem with it myself.

Personally i would never mix tyres especially on a performance car

You might have erroneous warnings from your tire pressure monitoring system - i have heard of that when mixing runflats and non-runflats. Not sure if that's true or not.

 

[Jeff_Seymour]

I just need it to be safe. I'm not a "Ricky racer" but more of a "look good Louie" type guy if you know what I mean. I just want a smoother ride and save some money doing it.

I have non-RFT tyres on the rear and RFT tyres on the front for the same reason. I've done 15,000 miles like that and have no problems what-so-ever!

 

[Jeff_Seymour]

Hey "X-S-Z" Did the company that install them give you a hassle saying you have to have a spare tire? That is what 1 company said to me.

Check your insurance.

Kwikfit (UK installer) queried whether my mix would be covered. Say you have a blow-out with a non-rft, the consequences may not be covered. A Z4 is designed to have RFTs in their eyes.

Be interested to hear what they say.

I had about 4,000 miles worth left on my rears but just let them go when I swapped to non-rft. Not worth much to anyone, and not really all that good either all considered. PS2 ZP's I'd keep, but not oe Bridgestones.

Considering the difference in jitteryness, I'm not sure I'd want oem rft at one end and not at the other, could feel a bit, errr, odd

Remember too you'll have a huge difference in tread wear, one set new tires vs old tires. Most on the forum (including me) will tell you it's not a good idea to mix brands/types of tires. However my knowledge in that regard is based on what I've read on tire rack sites etc. There have been a decent number of problems/complaints in the problems forum about handling from people that have mixed tires.

As far as your upgrades, Both Falken 452's & Eagle F1's come highly recommended on this forum. Personally I'd stear clear of all seasons as they aren't going to perform as well as tires dedicated to summer/winter.

Simple answer to your original question - NO. I would never even consider mixing tires like this. :brucelee:

The only problem would be a "what if" situation. For normal everyday driving I don't think you would have a problem. But, in a clutch situation I think you would find that you have more under steer which would be worse on wet roads. But what the hell, there are millions of FWD cars that live with the same situation every day.

I run that way in the winter months with no trouble what so ever.

X3..

There's no issue mxing tyres if you have matching pairs on the same axle. Mxing on the same axle probably isn't a good idea as youll get a lack of consistency in your cornering. There's no danger in it it's one of those things that people instictively say they wouldn't do but there's actually no problem with it. I have stock contis up front and ps2's on the rear of mine. Guess what? It's fine

I bought the car from an independent BMW dealer and said I wanted new tyres on the rear and he fitted new Bridgestone non-RFTs. I didn't know enough at the time to specify what tyres I wanted... But on realising I wasn't about to change out a brand new set of tyres on just buying the car, I have had no problems. I am nearing the end of the life of the rear tyres once again with the fronts still fine.

Well, a good tyre brand at each end is probably ok for 95% of driving, I'd be fine with that, but oe rft mixed with a nice new non-rft might be a bit iffy, imho

 

[no fit state]

I've got Falkens on the back and Bridgestone rft on the front. Been like that since October, no problems in any weather or at any speed

 

[Jeff_Seymour]

So Thursday I am replacing the back run flats with Goodyear Eagle F1 all season. My fronts are still run flats. I'm living pay check to paycheck so I will have to wait until I can replace the fronts with Goodyear Eagle F1 all season in another month or 2 .
