Hi

Having suffered the cracked wheel issue on both my rears, I've decided to go to non-run flats all-round - I did this on my Z4 previously and it undoubtedly improved the car, and I hope the additional cushioning in the sidewall will limit the chance of any further wheel issues. I didn't particularly want to do this this time as my wife is pregnant, but I feel I have no choice now.

So, can anyone who has gone to non-RFTs on 19" rims on an E92 make any suggestions as to which tyres? At the moment it's looking like Conti Sport Contact 3's, which I can get for about 680 all in.

Any comments gratefully received.

Michelin Sport Pilot 2's are superb.
I paid about £850 for all four I think - same wheels/tyre sizes.

Ditto, best tyre I've used

heya

I bought these

Michelin Pilot SPORT PS2 225/35 ZR19 88Y EL with rim protection ridge

and obviously the ones for the back, they both have this rim protection ridge, what is this all about ? have I bought the wrong ones ?

No, you've got the right ones. The rim protection edge is an extra strip of rubber that theoretically sticks out beyond the actual rim of the wheel, thereby affording a little extra protection against curbing. In practice, it makes very little difference, as the wheels are so exposed anyway

Conti sport 3's, and goodyear assymectrics and Vredestein sessantas came out on top of PS2 in EVO tyre test.

Try one of those.

Remember though that the Evo test was conducted on a front-wheel-drive Golf, which has very different handling characteristics and requirements to a rear-wheel-drive car.

Go with the forum members' opinions - Michelin PS2s and the Continental ContiSport 3s. I have had both - the PS2s have more outright grip, especially in the dry. The Continentals are more progressive in the wet, and have better than average resistance to aquaplaning. Both tyres are very good - the Continentals are better value so I would suggest for all-round driving and taking cost into consideration, they would be the ones to go for. On the other hand, if you want the absolute last degree in handling and control, and are not bothered by the cost, then Michelin PS2s are the way to go.

Thanks for your replies, especially E92Fan for the detail comparison. I can get the CSC3's locally for a decent price, and given the above will go with those.

What do you do for puncture protection? In the Z4 I had an electric pump and can of squirty stuff? Is all 'squirty stuff' equal? M Mobility Kit worth considering?

Thanks again to all

Just get the M Mobility Kit. Or go to Halfords and get the Michelin Compressor, tyre goo, and a digital pressure gauge...

Incidentally, tyre pressures for your car on 19" wheels and non-runflat tyres should be 37psi at the front, and 38.5psi at the rear (that's a good starting point based on the setup used by Alpina for their B3 Coupe - you can vary a little depending on how you feel)

I know the Michelin PS2's seem to be the ultimate replacement for non RFT but why is nobody here trying the Toyo T1R?? I see a lot of people on the US side using this tyre and on cars with up to 500hp.

If I was changing to non RFT (which I may do sooner than later) then I would certainly consider the T1R as a contender. It has a AA traction, A temp rating and Silica compound. Seems (from reports) to perform better in the wet than some others in this class and has a 280 treadwear rating (which is twice the life of the OEM fit Bridgestones). I suspect they would also spend more time in contact with the road than the crappy runflats, which hop and skip everywhere

Regarding size, I would be looking at fitting the 235/35 R19 and 265/30 R19 respectively (though you can get get straight replacements in 225 & 255 sizes). A set of 4 from Camskill comes out at £605 - at which price I would buy an additional tyre as a spare and still be inside the price of 4 Mich PS2's

Interested to know what other people think

[dazzapb]

I got and recommend goodyear eagle F1 assims for around 700 fitted.

235/35/19 front and 265/30/19 rear, they fit great and so far so good! I kept the re050a's in the Garage to fit to the car come trade in time.

I got a few tins of holts tyre weld incase of minor punctures. It will actaully inflate tyre too, but a compressor wouldn't hurt!

As a bonus my BMW dealer purchased tyre insurance covers the new tyres, just had to supply DOT number and pay £5 per tyre registration fee!

Good luck!

[willhollin]

I was considering Falken FK-452s, in sizes 235/40/18 and 265/35/18 I can obtain the tyres for a little over £375.00 plus fitting. Has anybody on here experienced them?

[booforty]

You get what you pay for - Michelin PS2's are worth every penny

680 euros right? how much is that converted to US$? I got my conti sport 3 at $1020 shipped 225s and 255s (staggered) also a free navi for rebate (the navi cost $200) So it was a good deal! I realized that conti sport3s are a little narrower than PS2s.

Thanks for that - was actually wondering this afternoon what pressures I should put in them when fitted, so very useful info.

Dazzapb - so 265s will fit OK then will they? I was looking for prices for the F1As today but couldn't find 255/30s. And that tyre insurance sounds interesting - could you point me to any info on it?

Prissy - no that's £680 GBP, good bit more than you paid. Rip off Britain...

The standard 19" wheel size is 225/35/19 front, and 255/30/19 rear.

However, you can do a "plus one" size (which is what Alpina do, and I have done also) and go for 235/35/19 front, and 265/30/19 rear.

[GanjamanUSS]

I got the PS2's in standard size ! oh dear !

No idea what to do if I get a puncture

does the tyre fitter have to take anything off the wheel like the sensors, or does he literally just swap the run flats for the non runflats and then rebalance the wheels ?

anyone know a cheapish dealer I can ring up and order one of those m mobility kits from that will have one in stock rather than getting ripped off in chiswick or park lane ?

What sensors? I think the e92 TPMS runs off the ABS sensors in the hub (measuring differences in wheel RPM), so no sensors on the wheels/tyres.

So should be a straight swap and re-balance.

Didn't know that - thanks.

Correct

Hi I'am a new member, I have 2 335i se with 19" wheels the first is a march 2007 which I had from new and the other new September this year.
The 2007 one has now done 43K plus miles and has had to have new rear RFTs at 30k due to being compleatly worne down to fabric on insides only still 6mm on rest of tyre the fronts had signs of the same wear on inside part of tyre. I manage to get BMW to pay for a rear set of tyres as I got them to check the wheel set up as at the time this was one of the first cars with the 19" wheels and the sports set up that had covered 30k in a year.
They found the set up was slightly out so they paid for rear set.
This is the first BMW I've had with the RFT on and find the ride pritty crap and when you do find a pot hole it sounds like you have smahed a wheel.
As yet the rear wheels seem to be still wearing on inside not as much as before but still more than the rest of tyre.
I'am keeping a eye on the new one (wife's) which has now done around 2k plus miles.
Is there a issue with the bmw brake down if you change from RFT to normal as you will not be carring a spare if you get a puncher, can you mouse the tyre with out any damage to the tyre presure warning sensore?

It might not only sound like it has smashed.... See this thread for that story.

As far as I understand it they will pick you up but will only take you to the nearest BMW garage (or tyre place?), not all the way home. I think my wife asked them that last week, I will double-check later.

Unless it has changed since I had a Z4 the tyre pressure sensors are actually the ABS sensors, so you should be fine
