#2 of 11 Getting a GS45h tomorrow: tire questions -- help! by argelius Feb 27, 2007 (3:25 am)
(My God...I'm the only one to post here)... I've read and read many posts about winter tires and runflats but I remain really clueless. (I know NOTHING about tires -- always just kept whatever the factor tires are).   I am picking up my new 2007 GS450h tomorrow :wiggle: which comes with all-season runflats.   I currently have a BMW330xi with runflats which I have found to be loud and rough (I think) -- not sure how much is due to the runflats and how much is just characteristic of the BMW "road feel".   Anyway, my concerns with the GSh's run flats are: [1] How loud/rough they will be. (Hard to really tell from just a couple of test drives). I am looking forward to a more smooth and quiet ride than I had (which I am sure Lexus will deliver with or without runflats).   [2] What my winter performance will be. I know in the ideal world I could buy a second set of wheels and tires for winter (Lexus dealership will store and mount them free of charge), but that just seems like a hassle anyway.   I'm a car nut, but I know NOTHING about tires. :dunno:   If I wanted to get a good set of (non-runflat) all-season tires, any idea if I could get the dealer to credit me something for the brand-new runflats?   I know I should probably just take the car with the runflats and see how they work for me, but I really want to maximize my "thrill" with this new car immediately. Seems like the only downside to no run-flats is getting a flat tire and having to change it...   Thanks for helping with what I know had been talked-to-death...

Replying to: argelius (Feb 27, 2007 3:25 am) I've had my 450h with the run flats since last May. My first couple of months I was convinced I would replace the tires with a softer riding set. I initially found the handling/ride quality trade-off to not be worth it (I came from a 2001 BMW 530i with Continental Contitrac tires which rode great and had excellent handling characteristics). After several months, I've grown to find the run flats to be acceptable, even though I drive daily on the less than ideal roads and highways in the NY metro area and NYC.   I don't find them to be too loud. It does however take getting used to the fact that the vehicle is so quiet that much of what you hear is tire on road noise.   With two minor snow storms hitting the NYC area over the last few weeks, I have been pleasantly surprised to find that the run flats performed relatively well (my expectations aren't very high for a rear wheel drive car with these tires). It wasn't any worse than my BMW, which I attribute partially to all of the extra weight from the batteries. The traction control system works well.   Take the car with the run flats and give them a try. Look at it this way -- they'll only last about 15k miles anyway!

Replying to: argelius (Feb 27, 2007 10:26 am) I have the runflats on my GS450h and have had no problems. They are somewhat rougher and noisier but one gets used to them. Except for size BMW uses the same tires. THe hybrid has a 50-50 weight distribution and a lower center of gravity so it handles and corners exceptionally well.
#6 of 11 Run flats.. by jlo_one Apr 13, 2007 (6:40 am)
Hi, I was told that there is no room for a spare tire so that is why they use the "run flats." You have no need for a spare tire.   dunno Replies to this message: bmwconvert (Apr 16, 2007 9:23 am)

Replying to: jlo_one (Apr 13, 2007 6:40 am) There's room for a donut spare but not a full size one. Mine came with one. I think the determinant is whether they need the space for some optional electronics (stability/handling package or something?).
#8 of 11 pre-collision and active stabilization options by cbonetto Apr 19, 2007 (7:17 am)
I am trying to decide on buying a GS450h with or without the (pricey) pre-collision and active stabilization options. Are they worth it? does anyone have experience with both versions of the car.
#9 of 11 Runflats by tricky73 May 05, 2007 (5:52 am)
My 450h was delivered with Bridgestone (summer) runflats. In trying to learn what is inside the carcass, apparently there are 3 or 4 different approaches...tire within a tire, gummy stuff that plugs the hole, extra stiff sidewalls, etc. The only information I can find on my tires is the Firestone/Bridgestone phamplet included with owners manuals which implies they use the gummy stuff. Going to their link there is no mention of the gummy stuff trademark...they don't even list the tire that is on the car. The Lexus dealership is no help...anybody have a clue? The only comments I can find in talking with some tire dealers is they are very expensive and must be special ordered.
#10 of 11 Brake Dust Wheel covers by salsags450h Jan 21, 2007 (3:53 pm)
I just picked up my 2007 GS 450h and the front wheels generate a lot of brake dust. Kleen Wheels does not have a brake dust cover designed for the GS hybrid. Do you know of a manufacturer that makes a brake dust cover?
