Abz Posted March 6, 2016 Share Posted March 6, 2016 Hello All, I know quite a few of you drive BMW's as 2nd cars and wanted to capture your thoughts. A lot of the newer ones have run flats fitted as standard, which personally I feel has ruined the handling. As no surprise, my wife has advised we have our first puncture on our 645 and we have only had it less than 6 months. Reading up online the views around RTF seem to verify massively from sensible conclusions to BMW fanboys. My only experience is this puncture and one where my colleague bought a 335i that had a puncture then couldn't manage more than 30 miles before he suffered a blowout on the dual carriage way (doing under 50mph) when we both travelled to Hastings. So should I change to normal tyres? It is the fronts that need changing - Anything I should be aware about? (FR Tyres are 245/40/19). Thanks Abz Quote Link to comment Share on other sites More sharing options...
Hitbox Junkie Posted March 6, 2016 Share Posted March 6, 2016 There expensive and don't last that long in think your best of changing to normal. Brother in law z3 lasted 70miles on a run flat but he nursed it home. Quote Link to comment Share on other sites More sharing options...
Al Massey Posted March 6, 2016 Share Posted March 6, 2016 Get normal tyres. Run flats are a waste of money Quote Link to comment Share on other sites More sharing options...
Scott Posted March 6, 2016 Share Posted March 6, 2016 Definitely normal tyres for the win. They're less noisy, handle better, cheaper and most places wont repair a runflat. Quote Link to comment Share on other sites More sharing options...
Hobgoblin Posted March 6, 2016 Share Posted March 6, 2016 There may be warranty implications; I imagine the manufacturer, and the insurer, will view changing to non runflats, as a modification. Quote Link to comment Share on other sites More sharing options...
Al Massey Posted March 6, 2016 Share Posted March 6, 2016 Tyres can't be classed as a modification. That's just like saying using a different oil or coolant would be classed as modifications as its different to manufacturers recommendation.

Hobgoblin is correct - be an idea to inform the insurer as they can wriggle out of a claim if they spotted it. Quote Link to comment Share on other sites More sharing options...

Not a chance. That's like saying the insurer would default if you didn't use the same brand as the car rolled out the factory with. Where would it end?

Where would it end? I reckon they would argue that they were a different type of tyre. Quote Link to comment Share on other sites More sharing options...
Scott Posted March 6, 2016 Share Posted March 6, 2016 I reckon they would argue that they were a different type of tyre. They may argue but there's no way it would hold up surely? My car comes as standard with 18s and runflats with a standard tyre option. There's also a 19" M5 wheel option which my car was specced to out of the factory. There's no way they could un-warranty my car due to a factory fitted modification, and to that end there's no way they could un-warranty any model due to performing a similar change of tyres when it's an available option as standard. When I called the insurance company I told them it was completely factory standard other than factory upgrades, they didn't even ask what they were they just took a note of what I said on my records.

Scott Posted March 6, 2016 Share Posted March 6, 2016 In addition to that, you would effectively need to tell the insurance company every time you changed tyre width as well if that was the case. Quote Link to comment Share on other sites More sharing options...
Al Massey Posted March 6, 2016 Share Posted March 6, 2016 Hobgoblin is correct - be an idea to inform the insurer as they can wriggle out of a claim if they spotted it. They can only wriggle out if it was faulty/bald tyres. Different tyres, brands, makes, models will not matter to an insurance company. Run flats are a recommendation.

fastcar Posted March 6, 2016 Share Posted March 6, 2016 Get rid of them!! My aswell just use a can of tyre wield:D Quote Link to comment Share on other sites More sharing options...
jamesmark Posted March 6, 2016 Share Posted March 6, 2016 Personally I would get rid. And as for the insurance, 'oh no they can't, oh yes they can' debate. I would, as a matter of surety call them for the EXACT letter of the law concerning the policy you have with them and what they think about altering the tyres. (I am with the 'it won't matter crowd, as surely as long as they are road legal' but hey insurance companies are not that logical) Quote Link to comment Share on other sites More sharing options...
