19" Alloys Runflat question

[NS66]

For those running 19" alloy wheels who have switched from run-flat tyres to non-run-flat tyres, I would be interested to hear your experiences.

In addition to the commonly noted improvements in ride quality and handling, have you found that non-run-flat tyres with 30/35 profile offer better protection for the rims—specifically in terms of reducing the likelihood of cracking or damage?

My E89 currently has recently replaced alloys due to previous cracks, along with nearly new Bridgestone run-flat tyres. I am considering switching to non-run-flats, but I am weighing up whether it would be better to use the current tyres until they are worn out, despite the compromise in comfort and handling.

You'll get as many opinions on this as ever..

My view is that the 326M / 296 alloys are just flawed..and they seem to crack with or without run flats, I don't know anyone who has fitted higher profile tyres on these alloys and can state non cracking..

On other alloys a higher profile will improve ride comfort / have no impact on handling and MAY improve resistance to bending / cracking.

Personally I'm on my last set of 35/30 tyres and have my 437Ms on 40/35 and my Arc-8s will move to 40/35 when tis set is done..

How long will it take you to wear out the current tyres? And are your new wheels completely crack free, currently? And what is more expensive, new wheels or new tyres?

As for crack resistance, its all a sliding scale. Non run flats will be slightly less prone to cracking rims, but theres only so much wafer thin 19" tyres can do.

Personally, id buy non run flat tyres. The likes of kumhos dont have to be expensive, then sling the current run flats on FB marketplace.

Thanks
@B21 - never thought to up the profile to 35/40 - any issues presume need to do all 4 in one go?
@ Brillomaster - makes sense - no experience with Kumhos was thinking Continental or Good year - never been a fan of Bridgestone's to be honest.
