Changing run flats for self sealing... good or bad?

Hi I’m new to in here so if this was discussed before ... sorry

I bought recently Bmw f10 520d 2014. At the back it has nothing special but new maxxxis m36 and in front one good Hankook s1 evo2 and really worn off old continental on passenger side. I will be replacing two in front and I will be getting Goodyear eagle f1 a3 . My idea is to get self sealing version as it basically does same thing as run flat but even better..... only question is can I do it? Is it ok to have run flats in the rear and self sealing in front ? Is that affects insur? Any advices ..... ideas ....please let me know

 

Hi!

That’s quite a predicament, ultimately, yes you can do it, however, at the same time No you shouldn’t
The handling characteristics will be terrible as the non run flat tyres will offer less flex due to having stiffer sidewalls
In short, Best to replace all four tyres

 

Can you get your size in DuraSea? I thought it was only lorry sizes they did in the self sealing

 

When i changed tyres on a Audi a6 i had at one time it had 17" self sealing on it.
The guy taking them off asked me what i had put in the tyres lol.

 

I'd never heard of them until reading this - scratching my head why i haven't .

Seems like a great idea to me, but i agree i wouldn't mix and match, and suspect handling could be effected, i guess unless they are like for like, as in the self seal have same supporting wall as the runflats.

Found this article for anyone else not known what these tyres are.

I decided to buy all 4 new tyres but I will stay with runflats as after talking to Goodyear I realised that we are living in the world ruled by money and insurance companies not in the world in which we can decide for ourself what is better for us and to be honest I couldn’t bother......, this is email from them
We do list in this size a 245/45R18 96W EAG F1 ASY 3 ST FP , this is designed for VW, although permissible to fot to any other make.

Some 5 series require a load index of 100 being an XL tyre , this is a 96 and standard load and therefore if yours requires extra load then this should not be fitted.

Also you will see that your tyres carry a * mark , this is the homologation of BMW and fitting none * marked tyres could effect the handling of the vehicle.
The sealtech will seal a normal puncture where the Run on Flat can keep going with more serious damage, should you remove Run on Flat tyres then we would recommend advising your insurance company as you are altering the vehicle from the manufacturers specification.

Can't wait for my Run-flats to wear out! I will definitely be changing to 'conventional' tyres. Changed them over on an E92 335d and difference was so much better!!
