thx

Nope, just swap the tires and you're done.

So I’ve been reading through this awesome thread, and I’ve been a lurker for QUITE SOME TIME now... so this is my first post since I now have to replace all four tires and get an alignment.

I have a 2017 330i (first BMW and I LOVE it) but it’s on RFTs and it’ll be $1200 to get them replaced + alignment. This is my daily and I drive about 18,000-21,000 miles/year currently. I live in sunny Southern California and new to more technical things (I’ve learned a lot here!!)

Would I be doing myself a disservice if I put on the A/S 3+ vs the 4SPS? I see it’s about $100/tire difference from those two and while I like performance and zipping around, I honestly don’t get to do it much. I’m looking for something that lasts much longer than my damn RFTs (preferably not cost that dang much either) but want a super comfy ride.

Would anyone help steer me (pun intended) in the right direction?

are you on 18" square, 18" staggered, or 19" staggered setup?

Thanks for the quick reply!

I’m on:

if you're 18" staggered, the tire sizes are 225/45/18 front, 255/40/18 rear.

nothing wrong with michelin pilot sport as3+ as it's the top ranked UHPAS (ultra high performance all-season) with high treadwear.

since you're in sunny southern california, i'd run max performance summer tires such as michelin pilot sport 4S or continental extremecontact sport, for a bit less.

for even less, an ultra high performance summer tire such as general g-max rs, falken azenis fk510, or firestone firehawk indy 500. the treadwear is not as high an UHPAS, though.

if you desire all-season, consider continental extremecontact dws06, general g-max as-05 or pirelli p zero all season plus as excellent alternatives if you want to spend less than the michelins.

This inflator/Slime kit (https://www.amazon.com/gp/product/B0732F1YZX/) that someone mentioned looks like an all-in-one, i.e., it will also work as a plain air compressor/inflator. Has anybody actually had to use the repair feature? Does it work, and how far can you drive once you've pumped the tire full of the Slime stuff?

[alohasurftoad]

i'd use slime sealant only if a tire plug kit is unable to get the job done. i'm skeptical, even if it's deemed tpms safe.

i have a scissors jack, breaker bar with 17mm lug socket, 12v air inflator and tire plug kit along with the other emergency roadside stuff.

Which would be most comfortable for a soft ride and would last longer, do you think? Also, how long do you think I'd be able to get out of them? On previous cars (driving around SoCal) I've gotten like 30k out of them easily with average wear before replacing... these are only last like 18-20k. Normal?

Also, my commute is like 40 miles /day with fairly decent roads.

I'm looking at these four that you mentioned:
Continental EXTREMECONTACT SPORT (Set of 4 = $784)
Continental EXTREMECONTACT DWS 06 (Set of 4 = $673)
Michelin PILOT SPORT A/S 3+ (W- OR Y-SPEED RATED) (Set of 4 = $773)
Pirelli P ZERO ALL SEASON PLUS (Set of 4 = $704)

Which would you recommend for my circumstances? I'm trying NOT to spend $1200 with alignment which is like $200 at the dealer... but I also want a really nice ride and a much longer range than my stupid RFs.

guys i was about to ask the same question, might as well use this thread - my ONLY concern about switching to non runflats is if i ...get a flat. What kits do you recommend?
i watched this youtube vid - is this basically what i need? (skip to 6m 45s)

i've had to get my car recovered once before for a separate issue, and watching it being dragged on skid blocks onto a recovery truck was not a pretty sight - although i now know how to unlock the ZF transmission to get neutral.

Even so, trying to fix a punctured tyre at the side of the road at night, in the cold, in the wet (i'm in UK) seems like such a daunting experience.

this is the only thing stopping me from making the move away from runflats.

EDIT: or do you guys just use those sealant kits? How reliable and effective are they? Does it make a mess on the wheel afterwards?

[alohasurftoad]

All seasons have higher treadwear number (500ish) than the summers (300-360) so they'll typically last longer.

Get the Michelins if you want the best performance all season.

Personally I'd get the General G-Max AS-05. Reasonably priced and probably better than its ranking indicates. Pirelli pzero all season plus also. I dont have experience with either and im going by what ive read so definitely do your own research.

Thanks man!

I think based on my own research, rankings, price, etc. I'm leaning towards the DWS06's or the 3+'s... would I notice a crazy difference do you think for the roughly $100 more (for a set of 4) difference between the two?

[alohasurftoad]

I believe the conti is more quiet and comfy and is what I would get between the two. You wont go wrong with either.

Thank you so much for the help! I’ve learned a lot.

Totally worth the switch. Ride quality is night and day. Even just went from 18s to 19s and the ride quality is better..

[chowser51]

Buy a plug kit and inflator. Maybe a bottle of slime. If those can’t fix it, call a tow. My tiny 16 yr old daughter had another flat in her Buick. She jacked the car up, took the wheel off, saw it was just a nail and decided to plug it, reinstall it, inflate it and drive home instead of putting her spare on. Took her less than half an hour. If she can do it, I’m pretty sure the rest of you can do it.

I have heard from a tire shop that using non RFT tires on a car requiring RFT could cause damage to the transmission and using non RFT would cause the car to be out of warranty in my country. It sounds very stupid, but there is a real story of a bimmer switching from RFT to standard tires and having transmission problem afterwards. Then the owner of the car had to pay for the transmission repair costs at the dealership as it inhailed the warranty conditions. I have heard this story from a honest tire shop. Ofcourse the transmission problem could be a coinsidence and had nothing to do with tires. What do you all think ?

Transmission problem from switching to non RFT? Nope. Simple as that, no need for further discussion because that's absurd.

Voiding warranty - depends on the dealer i suppose. It seems completely unreasonable to me, but i don't live in Europe. Who knows if there is some fine print that the dealer can point to in order to avoid a costly repair like a transmission. So again, unreasonable but i suppose not impossible.

I have a tire appt on next Monday to replace my RFT with non runflat PS4S, no hesitation at all.

[chowser51]

tire shop probably trying to sell more expensive runflat tires.
correctly sized tires should not hurt your transmission.
the first thing I do on any bmw or any car with runflats is get rid of the run flats. no issues. i do replace them with appropriately sized tires/wheels. i'm not doing ghetto stuff.

The price diff between RFT and non RFT was $150 for all 4 in my country for the pirelli p7 205 60 16 92w. As I have an old dad with health problems and this is his car, so I chose RFT for him so he will not need to get out of the car in the middle of nowhere just in case. I am a bit too cautious, but I do not want to be regretful then. By the way RFTs are really stiff but not too stiff at this size/brand/model. The factory tires were same brand model and size as well.

If I recall correctly the M3 and M4 with factory installed Michelin PS4 tires... ahem... are not run-flat tires and in the trunks are... a bottle of BMW branded fix-flat/slime and a branded pump.

Verified last weekend when I was looking at a CPO M4 and M3 2016 models.

Runs around $100-ish on US EBAY

Make sure you check the expiration date of the sealant. I have this same kit on my 2008 M3 and I checked the sealant last month. It expired in 2012. If I really had a flat on that car, the sealant wouldn't have worked at all.

I purchased a similar kit for my F30 when I got non runflat tires. It was a Airman ResQ kit. They're from Germany and seems very similar to the kits you'll find on German cars.

Doing the same thing; finally decided on the Firestone Firehawk Indy 500 for $707 out the door at the Firestone store near me. Actually they were $20 cheaper than if I had Tire Rack ship to them and had them install. Was considering Nitto Motivo for a while ($810 out the door at America's Tires). Good Luck.
