Anyone regret going away from run flats

Id like to hear from
Folks who ditched the run flats and then had to deal with flat tires.
Id have 3rd row so I cant carry a spare (but do keep a FS spare in my race trailer).

I would love to ditch the run flats but am concerned about using fix-a-flat type solutions damaging the TPMSor just not working well or gong too much hassle (cleaning it out later).

Thank

John

I switched from runflats to non... but I don't have third-row and I added a spare. The difference in drive was not very noticeable between tires.

If I wasn't able to carry a spare, I'd probably keep run-flats. And now that I think about it.... since the wife was the primary driver, I should have probably kept the run-flats.

Edit: I have not had to deal with a flat tire.

I ditched the run flats, but have not had a flat tire yet. My wife is the primary driver.

I have the 3rd row seats. In the back storage compartment I have a 12v powered air compressor, plug kit, and a can of fix-a-flat. I also have roadside assistance through my insurance company. My mentality is this: when we travel for vacation/longer trips I will probably be able to fix a flat tire on the side of the road. The fix-a-flat is there as a last resort. In the event a tire is irreparable I would have to use roadside assistance. When my wife drives, I can stop over and help her out if I’m nearby, or she can use roadside assistance. I don’t expect her to be able to change a flat tire on the side of the road, especially with large SUV tires.

My daily is a Tesla Model 3, it does not come with run flats and has no spare. I have almost the same setup for supplies in my vehicle.

Sounds like I should get a nice visit compressor, a tire plug kit and a pair of visegrips to remove nails/screws. Thanks for the feedback. Im ditching the runflats.

Yes! Forgot to mention the pliers. Some kind of multi tool that has pliers and a knife would work well.

What Runflats are you running? They aren't a model. It is a feature....

I've had Michelin Lattitude Tour HP ZP for the last 2 sets (255/50R19).
My overall experienced with this tire model has been very good. They are quiet, smooth, but yes stiff/harsh on bumps of any size. I find the stiff sidewalls are a plus when towing.

Traction and handling have been above my needs in all seasons but I don't drive like an idiot on public roadways (I get my speed jollies in a real race car). With my previous BMW's, I've always had dedicated winter/summer tires, but these Michelin's on an X5 make the benefits of dedicated-season tires not worth the trouble.

They have 38k miles on them and are at 4/32'nds. They need to be replaced in the next 2-3 months in prep for winter. If I lived in a more temperate region, I'd say they would last to 45k miles without a problem. Today we had torrential rains and at 4/32nds tread depth they handled the raing and huge puddles without drama. I would recommend the Lattitude Tour HP ZP's without hesitation to any X5 owner.

However, non-RF like the Pirelli's are over $450 cheaper per set, and I know they will ride much more comfortably and last much longer. With two kids at private universities, this represents a meaningful savings. My wife says I should just give up racing, but that's ridiculous, right?

Good feedback. I like that tire as well, it is the best runflat one can buy. IMO


I get ~45k on mine, but I am a stickler on alignments. Also, since it doesnt rain, if I approach 4/32 and it is entering the CA summer, I am fine running them to the bars.


And your wife is talking crazy.....

I ditched the RF's on my previous X5 with 3rd row and just kept a can of fix-a-flat in the boot cubby. Luckily we never had a flat even with crap Michigan roads. Much cheaper and quieter. My new X5 is not 3rd row and has a spare. Currently the as purchased tires are big $$$ Michelin's but I plan to downgrade when the time comes. We ran Mastercraft Courser's on the old X5 and they were great.

This brings up an interesting point ... I just purchased a 2013 E70. Which tire mentioned do you like of the above mentioned? How do I know if I have run flats on my E70. Run flats and no spare are all new to me as I'm coming out of an E39...
Thanks in advance!
Give up racing???!!! What does she mean? That's just "flat out" crazy!!! LOL
