tire issues on 20s?

thinking about coming out of my f10 which had 19s and a nightmare of a time with RFT and bubbles etc. are there problems with 20s at all? are they durable in tough weather? i love those 336s but trying to see if they are tough enough for a new york winter.

anyone?

A new york winter is tough???? You've GOT to be kidding me.

IMO the 19" rim and tire is far superior for an SUV. But I buck this silly 'big wheel' trend, for the (imo) misplaced sake of 'style'....

Buy something with Michelin Latitude All Season runflats, and a spare tire (skip the warranty) and you'll be fine. Roll up to discount tire (or whatever they have in NY) and buy a road hazard plan for the 4 new tires, cost you $150.

trust me, nyc winters are different. the streets get torn up like it's thunder dome. your opinion about big wheels are duly noted. so you think the m latitude is the best tire? road hazard i think is a little more than $150.

have had a very tough experience with the wheels on my 550, just trying to avoid that occurring again. what tires come with the 20s do you know off hand?

thanks for responding. this board is not as lively as the F10 thats for sure

Born and raised in NYC .... lived in a good many place with bad roads...

Sizes? Off hand dunno.... But here is a little trick:

all tires/wheel combos have the same overall tirre diameter..so as you upsize rim you simply lose sidewall. The 20" has 1/2" less sidewall as compared tothe 19"... I seem to recall 28" as the OD, so you go from 4.5 to 4... very roughly as the tire compresses of course.

Finally, do you know which road hazard I am talking about? $35 or $40 per tire, give or take., Not the BMW rip off.

As I recall the tires on your F10 were a MFG defect, no?

And of all the tires that people bad mounbt, year in and year out, the Michelin seems to be dramatically under-represented....

IMO

I agree with ard. 19s on the x5 look great. Ride quality on the 20s is going to be stiff and winter traction poor. I have m latitudes on 19s

Although I am a supporter of 20 inch wheels, if I still lived in the upper peninsula of Michigan, I would have never considered them, as you do feel everything (and those roads have alot to feel)

well they weren't necessarily a defect but were very poor none the less (i speak of the horrible eagle ls2). i had 6 bubbles in manhattan on stuff that i would consider tame. but i am picking up that 20s are a little bit of overkill. still, havent heard of any issues with losing tires in the city which is big.

thank you for the michellin information.

what wheel options do you guys think look best in the 19inch category?

Hey,
I just switched from the stock 18's on my X5d to 20's style 336 with new bridgestone duellers. I had the same bridgestones in 18" version with 38k miles on them. Believe it or not i feel this wheel tire combo is a softer as compared to my 18" setup, i think due to the width. As Ard mentioned i didnt lose as much sidewall as you would expect, not like when upsizing on a car. There is enough sidewall of the set that I'm not worried about bubbles. I live near jersey shore where the shore towns have bumpy streets and can't complain. My ONLY complaint is you will sacrifice fuel mileage. I lost a good 1.5-2.0 mpgs going from stock 18's to 20's. You can definitely feel the weight at the wheels. It gives it a more solid hunkered down feeling, but not as light on its feet as it used to be. Sick overall look though especially with the fender flares. I'm 80% happy with my wheel upgrade. I would vouge for the bridgestone duellers. I was at 38k and still had some life left on mine. I also rotated them every oil change.

IMO 20's are the best look for the car, but may not be the most practical, it depends what you are looking for.

.

with 20s, and no rotations, it will be interesting to see what that mileagew drops to.... my guess half or so...(depending on alignment)

do you feel as though the truck drives more "car like" with the 20s vs the 18s? I'm coming out of an f10 which needed a bunch of modifications (non rft, din an suspension) to be up to snuff but have heard great things about the way the e70 drives with AD . i can trade MPG for sure. i can't trade road hazard, but i have a very high tolerance for that given the recent experience.

I am AVERAGING 24.5MPG with my 20-inch wheels (214) and Continental DWSs. I only have 500 miles on the vehicle so far but pretty decent fuel economy (for 20s)

You'll be fine on 20s, it's not like they really have that low a profile, you still have roughly 4.3" sidewall, the 18s on my 135i only have a 3.5" sidewall for comparisons sake.

I chose the Latitude Tour HPs, I originally wanted to get the Continental DWS's but given the fact that they go out of stock all the time and Continental can never provide a date for the next run. It doesn't leave me with a good feeling that if I did have a problem with one of them, I'd be able to get a replacement easily.

"car like"?? What exactly IS that?

Understand what it is you are trying to achieve- in concrete terms that translate into real performance changes.

i've never found larger wheels to make a vehicle handle more car like...

when i had my 18's i used to run my tires around 40 psi for mileage concerns, I have yet to check the psi the dealers put into my tires for apples to apples comparisons. So far it is a smoother ride from the seat of my pants observations. If it werent for the drop in mpg's i'd be 100% happy with the upgrade in size. For looks it is night and day from the stock 18's.

yeah its not apples to apples. just wondering if the RFT gave anyone problems. i still have nightmares about the f10 19inch OEM tires/wheels

Actually, they don't know what you mean by car-like ride, and 'up to snuff' in terms of a dinan suspension... But there are always plenty of people willing to blather on about how bigger wheels make for 'better' whatever...

If yoi believe dropping run flats and going to bigger rims will make your X5 be 'car like', enjoy.

i believe it will, and that they do. thanks for your input. you must be the resident x5 bully?

Hey Highyo

don't you remember in junior high, if you respond to bullies, they keep bullying, so pay no attention... I understad what you meant by a car like ride, so don't worry.

Anyways some useful info for you. I checked my tire psi as we hit a cold snap here in NJ, 50's during the day 40's at night. My front tires are at 29psi and rears at 32psi...both way too low, could explain the serious decrease in mpg and softness. I will report back to you in a couple of days. Going to increase psi to about 38 in each and will let you know.

haha you're right, no reponses to him.

one of the things i did with my F10 was code it such that i could see the temp and psi of each corner. my tires went below 30 on saturday as well, owing to the cold. i'm going to get that done straightaway when i get the e70.

i'm definitely going w 20s for the "car like feel" and "totally awesome big wheel look" that everyone loves so much

ARD, does indeed come off as an aggressive bully, he's harmless, and actually has contributed to the x5 forum. But again I can see where the bully phrase comes from LOL.

Back to your point, the 20s won't really achieve The car like handling ur looking for IMO. The sidewalks are nonexistent for the 20s, but u will gain some
Added grip except in inclement weather (where I can guarantee u won't like the 20s). If ur looking for car like ride, u might want to stick with either 18s or 19s. The only other options that will help are adaptive drive to help u not feel the difference between a Sav or car.

Btw I too love the f-platform electronic psi monitor. Unfortunately last I heard, people have been unsuccessful in coding that too work (e70 that is). I believe the hardware is incompatible with the software codes.

The OEM 20" Bridgestone runflats ride great, night and day between them and the RE050As on my 135i. I've never tried the Dunlops, but the Bridgestones are fine IMO, the only reason I changed is I needed something that could handle some snow.

Best of both worlds I run the 20's in warm weather & 18's with Blizzaks in the winter.
