Why Is There No Spare

yoon_209 · 07-20-2018, 02:43 PM

Excuse my rant... but this whole no spare business is absolute BS...

On monday i drove over a ceramic shard that punctured through my right rear tire.

Yes I had non-runflats but no run flat would have survived this puncture. The puncture was two inches long from what it looks to be a roof tile of some sort and to top it off i was 70 miles away from home... i then had to be towed back home and my car has been sitting since I have to special order my 255/35/19 tire... what an absolute shit show...

Why did bmw think runflat tires would be smarter than adding a spare in the trunk???

It’s not just bmw it’s almost all manufactures. It must save them money. Only solution is to buy a spare tire kit for 4-500. You can buy a full size spare but it’s going to take up a lot more space then the spare tire kit.

I agree 100% is BS.

To be fair, a RF might have gotten you home if the gash didn't compromise the sidewall. I think the problem is weight more than cost. To meet EPA mileage rules, car makers need to make a lot of poor choices. A tire, wheel, jack and mounting hardware is an easy target for some pencil-pushing idiot.

I tore a 3 inch hole in a RFT sidewall. Hit a huge pothole. Sidewall gave in a bit but still provided enough support for 20 miles to get me home and then to a local tire shop.

RFT would have definitely got you home (this coming from a guy with non RFT and no spare lol). I risk this everyday myself but carry AAA coverage in case of a mishap.

The reason that BMW chose to not include a spare is the MPG increase which gives them a bump for their complete fleet EPA ratings... and by default cost savings buy not having to include a jack and a extra tire. Its a win win for them.

It's not just BMW. When I shopped Mercedes I noticed they didn't do RFT, but they didn't do a spare either, they put a can of fix a flat and a pump in the trunk. I imagine it's the same with most brands now.

Very interesting. Have always wondered about fix a flat type solutions... imagine they would be quite the mess and ruin the tire (and prevent patching) when used?

Do you remember what brand MB supplied? Assuming it was rebranded as MB anyhow... considering picking up a can to stash in the trunk in case or emergency...

No idea, I just noticed that was the stock MB 'solution' to having no spare. They probably offer RFT as an option as well.

I keep a cigarette lighter air compressor and tire repair kit in my trunk, since I don't run RTFs. If I have a huge blowout I'm screwed either way, but it's good to have regardless for like $30 all together. Fix-a-flat does ruin the tire and prevent it from being patched or repaired.

The common brand I am seeing is Slime... which one do you use?

I've used it and it doesn't prevent you from repairing the tire nor does it ruin the tire. The main problem is that it can clog up the TPMS so that it shows no pressure in the tire, but at least in my case it eventually worked again.

Yep that's the one I use for the tire repair kit. I have a Hypertough tire inflator though. Slime has offerings but I liked the features/design of the Hypertough better.

Admittedly, I've never used one so I don't know from experience, but from what I heard, it can often times prevent the tire from being repaired because the goop it sprays into the tire is difficult to clean off as it is designed to bind to the inner lining of the tire, to clog the leak. It also makes a mess of your wheel for certain. Perhaps I was misinformed about the subsequent inability to repair.

Billfitz · 07-20-2018, 05:34 PM

It binds to the tire, but that doesn't interfere with using a plug to fix a puncture.

I am not a fan of rf, but rf could run with 2 inch of injury unless it cut open on the side.

You can't fix a broken leg with a band-aid either. But since the sidewall wasn't affected you probably could have limped home with it.
