335d tyres

[elise2000]

Hi All

Just had a service today (at great expense from a main dealer, with less than great customer service, but that's another matter).

Upshot is I need a new rear tyre. The other rear has 5mm tread all over. Would you bother replacing both rears or just one?

It currently has the Bridgestone Potenza 5001s all around. If changing both rears, would you stick with them or change for something else?

Friends have said don't bother with more run-flats (and I'm inclined to agree as haven't had great experiences with them in the past). And have also recommended changing to Michelins or Hankooks which seem very decent for the money.

Thoughts would be appreciated.

Cheers

I’d advise ditching the run flats, just not one at a time. One RF and one normal across an axle wouldn’t be too clever I doubt.

Cheers. No reason not to have run flats at front and normal at rear I guess?

Not really, no. It’s only cross axle you really ought to worry about.

Agree with the above

But if you don't have issues running RFT's then stick with them?

My pal has a 335d tourer and has just dropped onto Uniroyal RainSport 5s (non-RFTs) and he absolutely loves how it's transformed the ride; more smooth, quieter and takes the rougher roads better.

He got them from Camskill around £90 a corner IIRC and paid to have them fitted locally

IIRC Uniroyal do RFTs too; so worth looking on Camskill to see what they offer

You could always go with a part used single tyre match to your existing 5mm, and then change both as a matched when required.

PS4 or 4S seems to be the default, definitely improves ride and handling, depends on your priorities really.

I ran Rainsport 3's on my 2017 530d xdrive and they were great for comfort and fantastically grippy and predictable in the wet. Rainsport 5's seem to keep most of those pluses with slightly sharper feel.

I would ditch the RFTs all round if you can afford to. Firstly, it will improve the ride more than doing just one axle. Secondly, keeping RFTs on one axle could make the car break away at different ends in different conditions. My own experience was that runflats were especially useless on uneven surfaces when cold, but could be grippier than equivalent non-RFTs on perfect tarmac...

[stewart rix]

Absolutely agree - never mix RFT with non-RFT's in any circumstances. However, to counter the nay-sayers on this forum, I have never found run flats to be as ruinous as many folks make out - in the past I've used non-RFT winters and noticed very little improvement in ride comfort. The 335D Xdrive has slightly softer suspension (without adaptive) anyway (we have an late F31 facelift). In fact for me I'd far rather have the 'comfort' of knowing that I won't be stranded on the side of the road trying to change a wheel or fill a punctured tyre with some sort or repair goo.

Thanks for all advice.

I’ve ended up going for a pair of Yokohama’s. So far they seem very good.

I’m leaving the run flats at the front for now, then will change at the end of the summer.

Hi all

So the tyres around town seem very nice.

On motorway though a different matter. Going around corners at any speed there is a slight loss of traction and the traction light comes on...

Do you think think this could be because they’re over inflated? Or due to mixing the tyre types?

Thanks

What pressures do you have them at, and how many miles have you done on them? I'd be a bit concerned if the TC comes on when going around corners on a motorway.

Think they’re 2.6 bar. Will check in the morning. Have done about 700 miles.

I always swapped the runflats for normal tyres.
I did this on 2 x E90 320ds and an F30 335d. As pointed out above this isn't as noticeable on the F30 X Drive given the softer ride. My 335d had Pirelli as standard, I went with Eagle F1s. No issues at all.

That is because you have mixed tyres front and rear.

This has been discussed ad infinitum over the years.

You can be lucky, but it more often than not it makes the car a twitchy mess. Wait till it rains and the back end steps out at 70mph while simply changing lanes to see how bad it really is. Or, maybe don't wait.


Running run flats on the front and non run flats on the back is to be honest pretty stupid, pretty dangerous and pretty irresponsible.
Get the fronts matching asap.

What Yokahama did you go for?

I hope it was at least an asymmetrical pattern tyre?

So if I change the fronts for the Yokohama’s you’re pretty sure all will be well?

Oh dear!



Not the best of tyres.

A bit late to the party here but mixing part-worn and brand new tyres front to rear isn't really recommended on X-Drives either! Apparently you can end-up creating problems with the transfer box unless you retain a similar tread depth all round so in the OP's case I think the best solution is two brand new tyres on the front to match those fitted on the rear. I'm not familiar with Yokohama's (so can't comment on those) but personally I found Goodyear AS2's worked very well on my old F31 335d....
