Need new tires, stupid question inside!

[Opus]

OK, a lot of new roofs going on in the neighborhood over the last few months and noticed I had a roofing nail in the back tire yesterday. It is almost on the side of the tire and tire place says it can't be repaired.

Now for the dumb question. My wife asked and I didn't know. Is there an issue with running run flats in the front and regular in the back? All my tires are currently run flats but was thinking of switching to regular tires and just throwing a tire repair kit in the trunk. Figure it would be about as useful as the run flats and regular tires should perform a lot better than the run flats. Tires are different sizes in front vs back so can't get any of the tire deals because they all require you to buy 4 tires. Plus the front tires appear to be in a lot better condition than the back.

I dont see an issue other that handling a little different. I believe the run flats have a harder ride to them. I had them on a corvette and didn't care for them much.

Nope.

That goes against what the dealer told me. Last time I was in for maintenance I asked about tire rotation. This was before I realized the front and rear tires were different. He said they do not rotate tires. It is better to replace 2 at a time. Oh well, looks like I'm going to have to just pay the extra for run flats. Wish these car manufacturers wouldn't go with run flats just so they can lower the car weight.

Well, pricing them out it looks like I can spend about $100 more and get 4 regular tires vs 2 run flats so may just replace all 4 tires. Guess there goes any live sales for me this summer.

I lucked out. Took it by Discount Tire after work and he said the tire was fine. The nail went in side ways and didn't even go thru the main tread. I guess the WWC live sale is back on now.

lol Ditch the rof's and get some normal tires.

What kind of car is it? Does it have a stability program (ESP), indirect tire pressure monitoring or direct (direct has metal valve stems and actual sensors).

I'm an Audi Master tech, that's why I am asking.

Ok, I that case all 4 tires need to be the same tire with the same speed and load rating.

The German cars have very sensitive ESP systems and you will get rogue ESP/ABS warnings if the tires aren't matched.

So I have to replace the 2 back tires with the exact same brand tire?

Well as i kept tabs on this i learned something about bmw, esp, and run flat tires. Glad i have a truck.

It is not just BMW. A lot of manufacturers these days are not including a spare tire to cut down on weight. When I was test driving an Acura, they didn't have a spare. They just had one of those emergency tire repair kits in the trunk.

 

[LCC]

i can see why they are pulling the spare tires. saves on weight and most people now days dont know how to change it anyway. not sure what they think the same folks are going to do with a tire repair kit. car should just come with one free AAA tire repair or tow.

 

[Opus]

I believe the tire repair kits are fairly easy to use. You connect the hose to the tire and plug it into the lighter socket in the car and it does the rest. I've heard different reasons on the no spare tire. Some say it is the weight which helps on gas mileage which helps the manufacturer meet their overall mpg ratings. Others say it is just a cost cutting measure by the manufacturers.

Google will have us all in flying cars soon so we won't need tires then other than for maybe landing.

 

[jasonrusso]

Yes, same brand, model, speed, and load rating.

When worked on BMW, I remember putting non approved snow tires on the M5s. At 60 Mph, the ESP system would actually detect the squishiness of the tires when you would accelerate. The 1/4" of slop from the rubber moving was enough to trigger the system

So I have to replace the 2 back tires with the exact same brand tire?

Welcome to sports cars and staggered setup's. Similar issue here over the last couple of years. New home, new construction, misplaced nails, builder doesn't want to pay for sweeper = flat tires. I actually stopped driving my car for this reason almost a year until they got a handle on it. I ended up with a flat or two and also run a staggered setup. I ended up just paying the price, found a tire that fit my driving style, and always bought a pair regardless of how worn either side was. This way I knew tires have even tread wear and not patched.

I will take my car on tracks and don't want to run a patched tire at speed or aggressive turns. Probably dumb but I run a no patch policy and replace them in pairs. Just glad the tire I like isn't cost prohibitive :)

This happens on pretty much all cars now. I worked as a service advisor at a Ford dealer for a few years. Had a customer complaining of abs light coming on. Front tires were worn visually more than the back and that was causing the abs light to come on. Two new tires later and problem solved.

Op, you can run to non run flats and 2 normal tires. Same load and speed rating. I be would highly advised against it, you would probably get some pretty good tire noise since the treads wouldn't be the same.

On AWD you’ll want identical tires but you didn’t indicate that your M is AWD

Its not an xDrive. No need for it here in north Texas. The tires have plenty of tread and since the nail didn't actually puncture the tire I should be good for another year, I only drive around 10k miles a year. Not sure what I will do when the time comes for new tires. Will wait and see what kind of condition the front vs back tires are in. The dealership said the back ones will wear out faster and they suggest doing them 2 at a time. I do know I will not stick with what is currently on there. Not the greatest reviews online, but I'm sure part of that is the $500 per tire installed price tag. I'm afraid to ask what the dealer would want for them. I will get rid of the car in early 2020 when the CPO warranty runs out so if I replace the tires next year I don't want to spend a ton of money on tires I will have for less than a year.
