    BMW 525i M Sport E61

    Show me your E61!

    My standard 525i M Sport, with lots of windscreen stickers due to too much travelling in Europe and in dire need of a good wash. It has plenty of optionals, but the one that I really could not live without is the Head Up Display, well worth it.
  2. I used to have a 550i saloon M Sport with 19" Spider alloys with non RFT tyres, and I can remember the ride was much more comfortable than the Touring with its 18" MV alloys + RFT. I don't know why I had to wait four years to switch to non RFT, but I guess better late than never. Good to know, I can confirm tramlining has disappeared, and the car is less sensitive to turbulent air, very noticeable difference when overtaking lorries. These must have been the best £500 I have spent on the car in my 4 years of ownership. I am really looking forward to using the car in Switzerland in the coming months on some proper snow to see how it performs. I am not expecting miracles, but it should be able to handle it.
  3. No issues so far, just remember to have your pressure monitor system reset when changing the tyres, otherwise you might get a tyre pressure warning a few miles after driving with the new tyres. That actually applies to any tyre change, simply because the new tyres are bound to be inflated to different pressures compared to your current ones. I cannot stress it enough, but if you are still undecided whether to change the OEM RFTs Bridgestones, don't waste time, do it and you won't regret it but try not to save money on tyre choice, there are plenty of premium tyres at good prices. Personally I had become so frustrated, that a few days before the tyre change I was about to trade in my car to get a new 3 series, all I can say is I am glad I didn't. I am finally smiling again while driving the Touring. The only issue I can see now, is I am becoming overconfident with the handling of the car. Three days ago it was raining really hard on the motorway, and I was the only one doing 70mph, everyone else was doing 60 or less.
  4. Hi everyone, I wouldn't normally open a new thread as a first post, but I thought this information might prove useful to some of those members looking to change tyres in the winter season so here goes. I have been looking on various forums for years to decide whether it was a good idea to switch to non RFT tyres but for some reason I never managed to convince myself. I have been running Bridgestone Potenzas r050a on all four corners (used two sets in four years), and I put up with the bad ride, tramlining, poor wet traction and road noise just because I knew this was the tyre recommended by BMW for the E60/E61. Lately with all the wet roads that I have driven on during this autumn, I started getting fed up with the vague (I am being kind, I should say dangerous) handling and started blaming the car itself. Standing water on the side of the road would just pull the car towards the hedges on the side of the road. Even on the motorway the car would feel very lose on wet surfaces. Before anyone asks me how many mm of tread I had left, I will say 6 at the front and 7 (practically new) at the rear, so the tyres should be able to clear the water. Two weeks ago, I thought as a last resort I would have a go at changing tyres and putting some non RFT tyres on. Since it's winter I thought I would try some winter tyres, I looked up at the German tests for winter tyres and I liked the Continental wintercontact ts850 P tyre (2014 design), as a bonus it topped most of the wet/dry and snow tests so I was really convinced. I ordered four of them for a little less than £500 and installed them at my local BMW dealer. They did confirm that I was aloud to run non RFT tyres, unlike some other dealers that try to tell you are only supposed to use RFT. Ideally you would need a space saver, but a repair kit should also be a viable option. Now for the first impressions. After about 10 miles of driving on a familiar road, from the dealer back home I had the impression they had resurfaced and filled all the potholes. I was hoping there would be some improvement but I would never have thought the difference to be so phenomenal. So that's one box ticked, ride does improve a lot. Second test was a few days later on a trip mainly on country lanes with mud and a lot of small bumps that would simply unsettle the previous RFT+M sport suspension setup, once again my confidence in the car's ability to cope with the bumps was restored and I did start thinking this was almost too good to be true, so I thought I should do a proper long run on the motorway with wet weather to really see if the car would behave as I would have always liked it to. The answer is that the handling is transformed, before with the Potenza RFTs, aquaplaning was always round the corner at speeds over 60 mph. With the Continental not a hint at 70mph. Interestingly but unsurprisingly, I can see in the rear view mirror that the car produces much more water spray than previously, indicating that the new tyres do clear water much better, so the grip is justified. Now this cannot be taken as a generalized comparison between RFTs and non RFTs. We need to keep in mind that the Potenza's have always scored pretty low in group tests, and the Continental ts850p is apparently one of the best. Maybe if I had some Michelin pilots sport RFT on the story would have been rather different. For reference, I use 245/40 R18 tyres on my 2006 525i M Sport Touring, and I enclose a picture of the new winter tyre I am using. Feel free to ask any questions, I'll try to answer in a couple of days. Also congratulations, for a great forum, plenty of useful information for everyone.
