Help- how can I replace tires and keep costs down

Hi

I'd be very grateful for your help with your insights into the issue below.

The tires on my car (2012 X5 x35d) need to be replaced. They are close to bald in the middle; apparently it was due to being over-inflated (odd, because I used to get the pressure checked at a garage).

Anyway, I know that when I end the lease it will need run-flats because that's what it has now, but I need to keep costs down now and plan to put regular tires, and deal with the run-flat at lease end.

I want to ask the community: can I choose any tires that fit the specs of my tires (255/55R18), in order to keep costs down - eg the cheapish tires listed below?

I know this is a premium car and the designers chose specific tires to maximize its performance, and some people would buy only the best tires irrespective of price, but right now I just want to get some tires on it that are not worn out, and need to keep my costs down as far as possible.

1) Is it correct that one should has to change all 4 tires at the same time, otherwise it may cause mechanical damage? That would rule out buying a set of used tires.

*or is there anywhere I can buy a set of 4 used tires that can have same diameter and can be used as a set.. eg if someone is replacing their tires and they have some tread left *

2) I realize that the more you pay, the better the tire overall, but is there anything wrong with the following cheaper tires (these come up when I plug in my tire specs which I think are 255/55R18 into a tire search on a major retailer):

(All I need is that the car will be drivable, obviously in wet or dry.. even if it doesn't maximize its performance)

General Grabber Ultra high performance light truck and SUV
Nitto NT420S Tire 255/55R18XL *
Nankang SP-5 255-55R18 109V XL BSW
Cooper Discoverer HT Plus Tire 255/55R18XL 109T BW
Dunlopp SP Sport signature tire 255/55R18 109V
Kumho Road venture APT tire 255/55R18XL *

Thank you all!

You need to change all 4 to keep them identical in diameter. Don't just change 2. You should really aim higher in the tire brand/quality to maintain the handling characteristics of the car, but of the list you provided I'd favor the Dunlop, Kumho or Cooper. You basically get what you pay for but you ought to be ok with those. If you buy from a Discount Tire and are really disappointed with your selection they will work with you to change them out to something better.

Thanks for the quick reply! Just out of interest, why do you favor those tires you list vs the Nitto or General Grabber ones?

Good question. Honestly just out of experience with the brands you listed, not with the specific tire you referenced. Don't totally cheap out on this decision to save $50 or $100. I just replaced all 4 tires on my X3 and after considering a similar set of cheap options ultimately I spent about $100 more and got a great deal on Pirelli Nero Zero size 235 50 18 and was put the door for $710 minus a $75 mail in rebate for a net price of $635. I feel like it was the right balance of tire, brand, performance and cost.

You have a $60,000 car, so don't totally cheap out on the rubber. It does make a difference in how the car handles and you have to live with the decision for years.

Just remember that the only contact your car has to the road is via tires. If your comfortable driving the family around with $100 less tires them I would dump the x5 and save your money that way.

Tires influence your breaking distance and can save you from a crash or aqua planing. Be safe, not sorry, because you're cheap!

Buy these: http://www.bimmerfest.com/forums/sho...d.php?t=788481

- top of the line brand
- run flats
- cheap(!), but shipping may kill the deal ... I suggest you try FedEx Ground.
- plus you're helping a forum member ... (and maybe he'll spend his new cash on other forum member items for sale ... )

How long until your lease runs out?

... or consider Falkens, available here: http://www.vulcantire.com/cgi-bin/ti...&f=ze950_t.cst.

Currently offered with a $50 mail-in rebate on 4, making this a good deal on a decent tire ...

Sumitomo HTR Sports are currently $488 for four from tirerack in that size.

For the rest of you, why the OP wants to save some cash is their business. I completely understand your passion for quality but that is not the question asked.

There is NO truth to the stupid, oft-repeated, tire-salesman-mantra of "uneven tires will cause mechanical damage". Nonsense.

Buy any tire that fits your car AND has the correct load rating...otherwise who cares? Really...

The cheapest crap tire is $~125. A top of the line non-runflat is $275. You save 600. You'll maybe get less handling and more noise, or whatever...for me the 600 isnt worth it, for others it is.

I reject the nonsense about safety, family, kill others on the road...all that. I am more concerned with a 16 year old taking selfies than I am of a 40 year old driving on chinese tires.

My 2 cents

I have experience with NOT changing all 4 at once on an all wheel drive vehicle. The day I had a flat on a Chevy Astro AWD van, I got two new ones on that axle. I got 35 miles down the Interstate when the rear differential exploded in flames.

Over the next 24 hours, I talked to a half-dozen tire guys, each of whom reported having just had a customer with a similar experience in a variety of AWD vehicles. All reported a differential burning up. The longest distance any of those customers got was 100 miles, and that was probably because the first 50-60 was short hops in town.

That was 15 years ago, and it cost me $1500 for the repair on a Chevy, not including the tires. I shudder to contemplate what it'd cost today on a BMW.

If I still have my X5d when I need replacement run flats, who besides Michelin makes run flats. Seems that you'd see more and more as these become more "normal".
I love Cooper tires, and great dealers who back them well in the Northwest. Unfortunately they don't make run flats to the best of my knowledge.

Thank you, everyone, for your comments.

PAX5 - my lease runs out in a year and a half. I've done 22K so far, but plan to do much less in the remaining year and a half. I may need to pre-purchase some extra miles.

I did expect that some people would find it odd to save money on tires given the car is so expensive, but as long as the car doesn't become un-drivable or fundamentally unsafe, I'm going to have to stick with the cheaper price range. Just what I need to do at present. Like someone wrote, I don't mind slightly less performance or more noise; right now probably anything is better than my current unevenly-worn tires

Two follow-up questions (for those of you still reading- thank you!):

my current tires have something like 'high load' printed on them; does that mean I should look for 'extra load' (XL) tires? I've read that it actually may not matter?

most tires (even more expensive ones) have a rating of about 2071 lbs from what I recall; is that sufficient for a car as heavy as the X5?

**My main concern is to avoid getting tires that are fundamentally incompatible with a car of such a weight, and I wanted to make sure I didn't ignore a spec, and find out afterwards 'Oh I needed a tire rated for XYZ". I'm not sure I fully trust those 'tire finder' things. The label on the driver door does say 255/55/R18 so at least that much I've got right (ie, these aren't the optional 19" tires)

I know that you are in a different country, but to have an X5 and to buy cheap tires, well I must be on another planet. Get rid of the X5 and drive something which costs less. Or borrow the $ difference and fit the right tires which will give you the right tread come lease return time and will guarantee a good driving safe car. Buying cheap now then buying again for the lease turn back is not sensible $ wise in my book.

OP- what do you plan on doing at lease end?

BMW will charge you $200 per tire, $800, if you do not have proper tires on it.

So what is THAT plan???

Unless you have a set of 'used but still legal tread' OE tires to toss on, the idea of buying cheap tires now may be a false economy....

Also. an OPTIMAL tire alignment (not just "Oh they checked it and it is OK") can get you 40k miles from a set of tires. (A bad alignment, but still OK by BMW specs, can get you 12k.)

As I said:

1. buy these: http://www.bimmerfest.com/forums/sho...d.php?t=788481, at about half what you would be forced to spend on trade in (not counting what you will spend NOW on economy tires), and

2. get a correct alignment, and

3. drive less than 10K mi until your lease is up.

I like your idea.

In case these get sold before I can finalize this... is it likely anyone else may be disposing of tires this way? Does anyone else ever advertize this?

Is it safe to assume these won't cause the nightmare problems with the differential one reads about.. because they were all run on the same car?

PS - what do you mean by a "correct alignment". Can I go to any tire specialist store for that, or does it have to be a BMW dealer?

(roughly how much should I expect to pay for that?)

^^People do occasionally sell tires like this. But lpcapital is offering a KILLER deal. Uusually it is 75-100+ per tire. See if the shipping can be managed- he had some very high quotes, but I think it can be done around 100.

Anyone can align this car. Please search for posts Ive made and the word 'alignment'. You will find threads where me and others dicuss this at length. Basically you want 0.01 to 0.02 on toe for each wheel. BMW allows 0.00 to 0.08. See?

Alignment is $75-120. Any good tire store, usually has a 99 special- give or take

+100%

If for some reason you can't pull the deal together because of shipping, or the tires have already been sold, you can shop for used tires in your area (e.g. craigslist. searchtempest.com) and use the following criteria:

All 4 tires MUST BE of the same brand

1. get a tire depth guage and measure tread depth across the entire tire profile in 2 or 3 different places. From left to right and ON TOP of the wear bar in the tread channel of the tire. Verify what the seller tells you.

2. tread depth cannot vary by more than 1/32 from left to right. If the shoulders are worn (very common for BMW tires), DON'T buy them.

3. NEVER buy tires with plug only repairs! One or two patches on the inside with plugs per tire is OK.

4. Try to buy tires with minimum 7/32 or 8/32 total tread depth (3/32 or 4/32 ABOVE the wear bar!), or more.

5. IMPORTANT: Production/manufacturing date should be younger than 5 years, and no more than 6 months difference between tires. Production date is found on tire side wall, usually a 4 to 6 digit alphanumeric code (see pic)

^ great advice for used tires in general.

I will add that if you are looking for lease return ONLY tires, you want simply "above 5/32".

A new tire is 10.32 Finding 7-8 32 is an almost new tire and will be more $$. Tires at 5-6/32 are in the 50-75 range.

Also, more likely to find a pair at a time, or singles. Why? Most shops convince buyers that "you need to replace all 4" those old tires get wholesaled as a lot, and small companies sell them on ebay/craigslist. I had a lemon return once, found a local ebay seller and picked up legal tires for $60 each (just needed two). $10 to mount.

No balancing...It WAS a lemon return

This is why i bought Nokian WRG2 SUV tires for our leased X535D. The OEM Bridgestones were awful, summer winter etc. So I got this to drive year round knowing I'd have to replace tires anyways before the lease came due. Buying a set of these was cheaper than a brand new set of RFT Bridgestones so I went with the better, cheaper, winter rated tire that I could throw on and still enjoy the car. When the lease is up, I'll pop those godawful RFTs back on and turn it in.

You can also go on eBay and get something good with 90% or so tread left. You may even find run flats that will fit just fine.

Thanks all!

I wanted to follow up about buying used tires on ebay etc - I've seen these on sale, but even pairs of 2 are not guaranteed to come from the same vehicle (I asked a bulk seller of used tires about this point specifically).

So although I like the idea, I don't see how this would l work for a four-wheel-drive car, where even minute differences in diameter can rapidly kill the transmission, from what I've read (and see posting above of someone's experience).

Or can you 'shave' tires with a kind of tire lathe (I've read about doing this for, say, buying one brand new tire to match the existing tires, but don't know who can even do this locally for used tires?) I only read about tirerack doing it, or one of those major tire sellers online.

1. You are missing the point. You will need tires to return your lease....THAT is why you buy used tires on ebay.

2. You do not need to 'match' tires...that is nonsense. Utter. Nonsense. Especially to return a lease...but even just driving around. I mean what do you do when you get an unrepairable flat tire, replace all 4?!?!??! The only people that say there is an issue are people that have a financial interest in selling tires
