Lexus SC 430 Wheels and Tires

kcrosby

I am trying to purchase a 2006 sc430 without the run flat tires. My dealer tells me the are not available but that they will change the tires (for a price). I have not found one person that likes the run flat tires. Does anyone know if I truley have to replace them myself? THis does not seem as safe to me as buying the proper tire factory installed etc.. Please help

As far as I can tell the runflat tires are a $400 option. You should be able to get a credit towards regular tires. I would check with a couple of dealers and use it as leverage to close a deal, without the change no deal. Spare tire kit is the question. Is that standard because the runflats are an option? I have an '03 with a new set of Goodyear Eagle F1s that are phenominal. I do not carry a spare but I do have the Conticomfort kit, which is a fix a flat type prodcut that is safe for the tire pressure sensors. I hated the Flintstone cement runfalts. What a beautiful car with the proper tires. Good luck

The dealer is charging me $900. to modify the trunk and to add a spare tire (donut). All of the literature about the car states that the run flat is an option but....he told me that they are all sent to the US with the run flat now.

I just bought a 2003 SC430 with run flat tires. Since
I don't like the ride and need to drive the car sometimes
in the winter on an emergency basis, I bought a spare tire
kit from lexus-parts.com for around $600 and did the change
over myself-takes about an hour to do. Am now waiting for
my Pirelli Nero's to arrive and replace these RFTs.

I am looking for some rims for my SC430. Were shown some Drifz 518S wheels and wanted to know if they were good ones. The price was $850 installed.
I think I would like some spoke wheels but can't find them in Raleigh,NC

Can you have RFT repaired//

heatmiser

Both the Pirelli Neros and the Eagle F-1's are "summer" tires not recommended to be driven in near-freezing temperatures or snow and ice. We don't get much of the latter here (Tennessee), but plenty of the former. Any other recommendations for SC 430 run-flat replacements (all-season)?

I recommend Michelin Pilot Sport A/S. They are doing a nice job on my wife's SC.

heatmiser

Thanks. I bought the Michelin PS 2's over the weekend, and can already tell the difference. I only wish I'd made the switch when I bought the car 16 months ago. At the dealer's suggestion, I put 265's on the back, and 245's on the front. It seems to help traction just a bit (and certainly looks better).

Great discussion. Does this mean that the only way to have an SC without the RFTs is to have conventional tires without a spare and carry a "fix-a-flat" kit? If a "donut" spare is possible, how is it accommodated in the SC?

heatmiser

I can't find the exact thread right now, but there's a discussion on the Lexus Owners' Club site [http://us.lexusownersclub.com/forums/index.php?showforum=3] about a spare conversion kit. I understand the Lexus dealership version may be around $900, but you can get another make (Acura, maybe) that works for a lot less. I've not done this yet, however, so I'd look into it first. Good luck.

I found this site using Dog pile, it even shows them on an SC

Couldn't stop laughing from that one.
Just replaced mine with Continentals.
And thanks for the tip about the Conticomfort Kit.
I'd buy a spacesaver tire but not for $500.00

I replaced my run flats about a year ago and love the new ride - what I was expecting when I bought the car. Since I do a lot of highway driving, I didn't want to get stuck in the boonies waiting for a flat bed truck. I did a lot of research on options and decided to get the mini spare.

My dealer quoted me $1100 for the kit. Instead I just bought the steel wheel for mini spare from the dealer ($130)Then I purchased the actual tire from a local tire store ($220 installed - pricey but I checked 5 places and they all were within a couple of bucks). The sppare fits nicely in the wheel well and the top still goes down.

I would like to know where can I buy the compact spare tire
for 2005 SC 430,size on manual shows 145/70R17 ,need the cover too.The dealer in town don't know perhaps I need a part number or go to different place.
Thank very much. Angelo5

angelo5

I forget to mention that I also need the spare wheel for the Lexus SC430 .Thank You

Has anyone replaced the Bridgestone summer run-flats with the Dunlop all-season run-flats? If so, can you tell any difference in the ride?

bbatts

Lots of people indicate great satisfaction and greatly improved ride with Goodyear F1/D3 as well as Michelin Pilot A/S Plus. I am in the process of replacing my Dunlop run flat tires and installing Michelin's from either Costco or Discount Tire with their lifetime balance and rotation.

heatmiser

I got the Michelins about a year ago and love them. I also got slightly wider tires on the back, and it really helps hug the road. Enjoy.

lucywest

OK, so I hate the ride on the runflats but I'm afraid to replace them because I've been told (by friends who should know, but still ...) that if I have a blowout on non-runflats with the low profile that the car demands, I'll probably lose control of the car. In other words, I'm not so worried about breaking down somewhere - I have a AAA membership (and could tow the car for the extra money I pay for runflats), but don't want to have a higher risk of tire-related accidents. Does anyone understand the relative safety/risk with regards to a blowout? Any help would be greatly appreciated!!

poppajoe

recently purchased a GS460 couldn't use my sc430 rims b/c of front brake pads much larger.also hv Lexus spare !!!!.Chrome wheels in prestine cond..no marks ,.wud like local sale live on West Coast of Fl. sake_joe@yahoo.com

bbatts

I'm switching from my Dunflops to either Michelin Pilot AS or Bridgestone 960 AS. Tire Rack rates the 960 higher in nearly every category, particularly ride. 960s are also about $50 bucks less per tire so I think I will give them a try from Discount Tire with new custom wheels.

eliotj

Can you tell me what brand and rim you use for the mini spare? Are there any other parts needed? Thank You!

My SC430 has 1 new Bridgestone Potenza RE040 RFT; replaced last week. Want to replace other 3 with Firestone Firehawk Wide Oval RFT. Anyone have a thought on how this will work out?

Just replaced my Michelin sport A/S with Goodyear GT from discount tire. Love the ride and handling and a lot cheaper than the Michelins. Excellent reviews on Tirerack.

oldersc430

My dealer says I have to get new tires immediately or risk death to self and family. The tread (original Bridgestone Potenza, 245/40ZR18) still looks pretty good and an independent mechanic said 2-3K more miles if not at speeds. I have 35,000 miles on these tires. My ride is as tough as it has ever been and it is super noisy. I want to switch to regulars. But then there's the Kit business ($1400 quote from my dealer). So, I'm with the others who are buying their own donut. What size? Also, in the $250 -$300 range - what's a good reg tire for handling (no snow) and noise?

graceanders

Lucy,
Did you every change your tires? I just bought at sc430 and I really really hate the run flats. What was your outcome?

jimbo409

What will happen if you just put on regular tires without the tpm sensors, will the light stay on and beeper stay on. Thanks jim

bbatts

I tried the Bridgestone 960 for about 45 days. Never could get a smooth ride, then Discount Tire identified 3 of the 4 were out of round. Discount Tire was great to work with but I lost all confidence in Bridgestone. I requested to replace all 4 tires with Michelin Pilot AS Plus. I gladly paid a little extra for the Michelin's and now have a great smooth ride. I'm not a hard driver, so a smooth, quiet ride is important. Michelin's do have a very slight grumble up to about 30 MPH that I did not notice on the Stones.

I put new snow tires on last winter without the sensors. The indicator light came on and stayed on......that was ok.

After approx 200 miles, 5the buzzer would come on approx every 3 minutes for about 30 seconds......a real annoyance. The dealership said that they could adjust the program to eliminate the buzzer......cost $250.

There has to be an easier way.

dprocyk

I installed new high performance snow tires last winter.......car ran beautifully throughout the snowiest winter in 20 years in Toronto.

I didn't buy tire sensors.......never had them or needed them for my previous 40 years of driving, and didn't feel like paying the roughly $800......the tire pressure indicator light wasn't an issue to me.

Trouble is the tire pressure buzzer started after a couple hundred miles. it was intermittent and annoying. Dealership said it would cost $250 to deactivate or activate this feature.

Anybody out there know an easier or less expensive way for deactivation of the buzzer ??

dbrockner

K all the dealers know that the run flat ride sucks. Use the knowledge to close the the deal or go to another dealer. Lexus dealers are just about as hard up to make sales as any car dealer right now. The buyer pretty much holds the cards.

baggins2

Have you installed your spare tire kit yet? If so, does it take all the room in your trunk? I understand that you can still put the top down but there is no room for anything else. Appreciate your response.

dprocyk

The run flats give an uncomfortable ride, and the spare tire kit takes up too much of limited trunk space.

I've moved to normal high performance tires, with no spare tire ..... I thought that my risk was low being that my last flat tire was in 1967 ..... think back to how many blowouts that you had in the last 20 years.

Allstate has a great Road Assistance Program for $14 per month which includes a replacement tire in the case of tire failure.

baggins2

Maybe you have the right answer. I did have one nail in my tire a year or so ago. I use this car only for local driving so it wouldn't be a great problem to have it towed somewhere. Probably wouldn't want to make any long distance trips without a spare, but I've got a LS460 for that, so probably wouldn't be much of a problem.

Thanks for your suggestion. :shades:

heatmiser

I agree with dprocyk -- forget the run flats and a spare. If you don't want to get the Road Assistance Program, carry a can of instant fix-a-flat for your typical nail in the tire situation. Knock on wood, I've been doing this for about 4 years now without incident.

I've replaced the Bridgestones with Michelins last week. The ride is comparable and the fist impressions are as follows:
Michelins are a bit noisier than Bridgestones with a high-pitched whine.
Michelins are noticeably stickier than Bridgestones and hold the road better.
Michelins are softer than Bridgestones and speed bumps are better absorbed.
Michelins of the same size look wider and beefier than Bridgestones.
With Michelins the car feels as I need to press the gas pedal more to maintain the same speed. Possibly this is due to the new tires being "stickier". It's too early to tell by the gas mileage.

A parallel experience is that I got a set of four and bought the road hazard warranty (insurance) because I had two non-repairable nails in the Bridgestones ove the past few months from highway driving. One thing to watch out for in the hazard warranty fine print is that the alignment needs to be in check for the insurance to honor the deal. Also check the agreement term as the tire shop may try to sell you the 1-yr warranty instead of a 3-6 yr for about the same price. Thus I also got the alignment service to have all bases covered. Will let you know if there are other insurance loopholes that I missed.

baggins2

Are you talking run-flat tires or standard tires?

tmakogon

regular tires

baggins2

Hey tmakogon. How have the Michelin tires working out by now? I am still debating what tires to put on. I'll have to make a decision soon as I have about 18000 miles on these. Any suggestions or recommendations?

Thanks.

tmakogon

Michelins are doing fine. Had a couple of nails in them, both repaired. Both times the tire pressure light warned me before the air was gone, so I was able to drive to the tire shop without the need for a spare. In case it's flat I carry a can of fix-a-flat and a compressor instead of the spare. Gas mileage is about same. Road noise has subsided a bit, but still noticeable. I can't say that one set is clearly superior to the other. Both brands are great tires.
