bazza_g Posted January 11, 2009 Author Report Share Posted January 11, 2009 Grip is hard to judge in these conditions, I think they have been scrubbed now and offer the same / similar grip to the PS2's. But as the roads are very greasy and its hardly above freezing most of the time in the morning I'm not about to push them hard. no kidding, my traction control light spends more time on that off at the moment Link to comment Share on other sites More sharing options...
Cliodejaniero Posted January 12, 2009 Report Share Posted January 12, 2009 There is no issue with ditching runflat tyres, Infact more and more are doing it now. As long as all four are being changed as ul be surprised the amount of people who want to have 2 runflats with 2 non runflats. I do know that you have to inform your insurance when switching however they will have no problem with you doing this. Link to comment Share on other sites More sharing options...
motiv4 Posted February 4, 2009 Report Share Posted February 4, 2009 Due to the recent snow my tyre pressures dropped and it brought up a puncture message on the idrive so I thought was a good time to replace all the tyres to non RFs (always planned this from day 1 but have been very busy and had no time to get it done) but I ran into some problems. No one wants/knows how to do them! Just curious as to what size tyres did u guys use on the 19"s? The RF on the car say 225/35/R19 on front and 255/30/R19 on the rears, but none of my local tyre shops have any non RFs to put on there instead. I specifically asked for the Goodyear Eagle F1s and the Falkens but no one seemed to know what to do when it came to replacing the RFs as they didn’t have that size tyre in those brands (wont the size be different anyway due to different type of tyre? width same but more height?). Local BMW service was not useful at all; flatly refusing it could be done?!. One of the tyre guys called up BMW and they advised I not change as it will mess up the spedo/TPM/invalidate my insurance!! I have not really had time to research this properly but from what I have read most people are not getting any of these problems! Any direction would be appreciated; I have tried searching the forum but can’t find any definitive answers! Any of you guys have recommended tyre guys near Liverpool or in Manchester that can sort this out properly? Link to comment Share on other sites More sharing options...
gizze Posted February 4, 2009 Report Share Posted February 4, 2009 Don't even mention or ask questions, just order teh tyres you want, take the car in and get them to fit them. I think it is BMW Belgium has now ditched run flats completely. The punture warning system works on rotational differences, there is no pressure sensor in European cars. You can put on 235/35/19 and 265/30/19 as well. BMW have not got a clue, they are read from a manual and that is all they can say to anyone. It would be advisable to tell your insurer you have changed, it won't be a problem though. Link to comment Share on other sites More sharing options...
richy_uk Posted February 4, 2009 Report Share Posted February 4, 2009 I chnaged Mrs Rich_y's RFs for a full set of Falkens. Event Tyres did a great job and it only cost £318 for a full set of 225/45/17's fitted at home. Really transformed the car and I'm so pleased they were chnaged before the snow arrived.

tinca Posted February 27, 2009 Report Share Posted February 27, 2009 Been following the run flat replacement conundrum across several forums. I've just bought a second hand, dealer approved E90 320D M Sport having crossed over to the 'Dark side' from Audi. Yes, these run flats are a bloody bother and given the harsh ride I'm keen to replace. Question is.....how do I know if my rims (standard v spoke M SPORT alloys) are EH2 or EH2+. Stealer tells me that I'd have to replace the rims if I wanted non-run flats.......hmmmm! Help! cheers, Tinca Link to comment Share on other sites More sharing options...
CarMad Posted February 27, 2009 Report Share Posted February 27, 2009 Its rubbish and a dealer being silly. I've not seen a case where you can't fit them, I've no idea what mine are but I've swapped to runflats on my 18" E90 M-Sports without problems and they are loads better and cheaper.

Help! cheers, Tinca I'm 99.99% sure you can fit normal tyres to ALL rims, but you can only fit RUNFLAT (Zero Pressure) tyres to certain rims specificaly designed to have then on. I think there is an extra ridge to help the sidewall stay in place, which makes no difference being there if you fit normal tyres. As soon as Mrs B's 130i's run-flats need replacing I'm sticking some Goodyear Assy's on, bl00dy run-flats are terrible and even worse when it's cold.

Just reading Carmad's response above and I take it you've swapped away from runflats and not swapped to run flats as stated above? Gald to hear that the rim stuff is total garbage and fully apprciate fitting runflats requires a special type of rim but not the other way! So from what I have read Falken f452's for about £400 would do the job nd no issues with damper settings, suspension, techy type stuff? thanks, Tinca Link to comment Share on other sites More sharing options...
tinca Posted February 27, 2009 Report Share Posted February 27, 2009 oh and one more thing.....if I fit normal tyres will it effect the Stealer's 1 year of remaining warranty? I bet the buggers would argue it was 'yer fekin blow-up tyres mate' if I go in with a blown turbo! Stealers eh! Link to comment Share on other sites More sharing options...

It would be worth notifying your insurance company about the change to non runflat tyres... as it could be seen as a "change to original spec" Link to comment Share on other sites More sharing options...

In the US you can buy the car without runflats if you want to so I doubt very much they could throw anything back at you. I called my insurer as well and they didn't have a problem with tyres being change to non-runflats. Link to comment Share on other sites More sharing options...
richy_uk Posted February 27, 2009 Report Share Posted February 27, 2009 Full set of Falken's on Mrs Richy's E91. Really transformed the car. Only £320ish all in from Event Tyres plus the cost of a compressor and some tyre weld stuff. Called the insurance company and they didn't have a problem. Also had a chat with stealer and they were fine too. If you get any stick, I understand there's a European country (Belgium ?) where BMW fit normal tyres. Also, I understand that new orders for ES versions of the E9x will come with normal tyres and run flats are a cost option. Link to comment Share on other sites More sharing options...
tinca Posted February 27, 2009 Report Share Posted February 27, 2009 Cheers all -clealry £400 quid spent now will prevent a whole day spent driving around tyre places wating for someone to tell me 'Ooooh Run-flat?We dont repair them mate but we can sell you one for £200.....but not the 225/40R18 you need coz we don't stock it.....be Christmas before we get one of them in mate!' One wonders if BMW suddenly got bored being sensible? They need to hang the chap that turned up to the office one morning and said: 'you know vee make zee best mota car in zee world, und it really is just uber fantastiche....vell, lets go totally blitzkreig and use zee tyre that does not repair, hardens in zee cold and makes Jonny English boy sheet his underhausen each time he crosses zee cats eye!' (Mind you, in the interests of political correctness, this may have equally come from a very switched on Female engineer given that runflats prevent tyre changes on exposed highways etc etc.....in which case good thinking that Lady!) Come on 'Vorsprung durch technik'.....now's yer chance! Crickey, I can see the Vulva boys in Sweeedun begining to mess their pants, they're so excited they could pull one over on BMW.....ok perhaps not then! On a serious note I take the point re. Michellin and Goodyear outlasting the Falkens given the mileage I do. Thanks for that. I'll report back on how I get on in the hope that it helps others consdering the same. cheers, Tinca Link to comment Share on other sites More sharing options...

bazza_g Posted March 5, 2009 Author Report Share Posted March 5, 2009 this may sound daft but what tyre pressures are my non-runflat Eagle F1's (18's) supposed to be at? Are the tyre pressures on the drivers door-shut valid only for the original run-flats? Link to comment Share on other sites More sharing options...
gizze Posted March 5, 2009 Report Share Posted March 5, 2009 tinka, you're going to fit in a treat round here, I can tell!! :D bazza, try 34 front and 36 rear. The run flats need really high pressures, proper tyres don't. Link to comment Share on other sites More sharing options...

SINGH Posted May 18, 2009 Report Share Posted May 18, 2009 Want to change my runflats tyres before my DMS map (Michelin PS2 + Bridgestones currently) for some non runflats, have seen some Verdistan Ultrasesnacs for £450 and Falken FK452s for £468. Which would you go for out of the two? Tyre sizes are the following (From memory): Rear: 255/35/18 Front 235/40/18 Anyone know any better suppliers, am I getting a good price? Thanks Link to comment Share on other sites More sharing options...
gizze Posted May 18, 2009 Report Share Posted May 18, 2009 I would check out the prices of Kumho KU31's. I had them on my M3 when I got it and they were great, far better than the FK452's. The Vredestein tyres are meant to get good reviews but I have never tried them so can't comment. Link to comment Share on other sites More sharing options...
CMC950 Posted June 5, 2009 Report Share Posted June 5, 2009 I need to change my 4 runflats on my 330i MSport today as car has just failed MOT on tyres! I intend to change to standard tyres (non run-flats) and Event Tyres are quoting about £650 for Goodyear F1 tyres, fitted. As most of you know the car is 40 profile at the front and 35 profile at the rear. There are cheaper options if I have 35 profile or 40 profile all round. What's the recommendation on that score? Another cheaper option is to have Goodyears all round but a different type of goodyear tyre at the front and back, is that ok? Thanks for any replies.

CarMad Posted June 5, 2009 Report Share Posted June 5, 2009 Go for the Goodyear F1 Assymetrics they are a good compromise for grip and cost. Replace with the same profile and fit the same type or tyre all round, if you don't you run the risk of compromising the handling of the car. You got a BMW because it drove well, don't ruin that for a few £££ Link to comment Share on other sites More sharing options...
gizze Posted June 5, 2009 Report Share Posted June 5, 2009 It is a BMW, it is RWD, it has a wider rear to prevent overtseer. The profile is a percentage of the width, that is why you have a 40 on the front and a 35 on the rea. Changing this will thorw your traction control out. I would not put F1s on a BMW anyway. Look at Kumho KU31s all round will be about £450 fitted. They will be a better tyre than the F1, alot of the M3 guys are now running them. You also have Falken FK452s, also a good tyre, will cost you around £400 fitted. What ever you do, keep the sizes, and DO NOT MIX patterns front and back, you car could feel like very, very twitchy indeed. Edit: The F1 asymmetricals are better than the GDS3s, but more and more people are saying they are not over impressed by them. I would stick with KU31s or FK452s or go the whole hog and get Pilot Sport 2s. Link to comment Share on other sites More sharing options...
