I have mine in the garage and based on early advice am putting these on stock rims on Weds....I have seen some issues recently on balancing but there ARE satisified owners who have done this; correct???!!

Again, Sumitomo 235/45/17 on the CLS stock rims. Please advise...

Slimey

If you already have them then just put them on. Why worry?

The tire is too wide for the rim. So when it's mounted the tire will be slightly round (on the bottom where it should be flat). Which WILL cause traction problems. If you can get the tire pressure just right you might be happy. But a smaller tire would be a better choice...

I'd send them back if I were you...

I have 225 sumitomo's... they are excellent. I know someone else who purchased the 235's for our car. He returned them for the 225's. As suspected the 225's are a better match and handle much better. The 235's will handle equal or worse than the stock tires.

Your causing the tire to couple sticking it on that wheel. You have 3 choices.

1. live with the performance of mismatched tires/wheels
2. buy different wheels
3. buy new tires

IMO the 235's are the best choice

Where's EricL when you need him...

SiGGy

What do you need him for?

reality.. tire is too wide for our wheel!

When you do that, you ARE causing the tire to not sit evenly on the road.

A fellow member had those tires on for 2 weeks. Said they were horrible. Tried all sorts of tire pressures. (He has sways and springs installed) Said they handled worse than his stock tires did. Went and bought the 225's and is much happier.

After graduating high school i worked at a tire shop. I saw people do this same thing all the time. They think because it's wider it's better. Which is true. but you need the wheels to accommodate the size of the tire. Technically your not getting as much usable tire now...

I have the Sumi's HTR+ in the stock CL-S size 21//50/17 and they are very nice. They look pretty wide enough and I think a wider tire than stock on these stock rims is overkill...but that's just me....

Slimey

I guess an addendum to my post above would be:

Why the hell did you order them if you didn't want to mount them? You had to know that they are meant to be mounted on a 7.5"-9" rim, and mounting them on the stock rim would be out of spec...right?

I have the 225's. They are great....i dont remember why I didnt get the 235's. I think they will be fine, too.

MikeS 18

I want to mount them but in the past 3-4 days there has been some dissenting opinions about the fit. Go back on a search about 60 days ago and everyone was saying that its a little larger but okay.

I have grown to trust Eric's opinions so that's why I call out for our wheel expert.

BTW, didn't you see this thread?

Ewww, a whole 2 people responded to your previous thread... If your only trust is in Eric why not PM him and delete this thread?... I ordered the 215 because I heard of balancing issues. I dunno, my friend you might not have a problem.. But do keep us posted if you go through with it...

I didn't state any opinions... you have been presented with the facts...

mattrush78 is the member who has been vocal about balancing issues with these tires on stock rims. There may have been 1 or 2 others, but I cannot find those posts at this time. The overwhelming majority of people who 'claim' to have installed Sumitomo's, Toyo's, or other brands in the 235/45/17 haven't complained about balancing this particular size on the stock rim ... if anything, they've encountered some alignment issues but have been able to overcome them. There could be a legitimate problem with this size on the stock rims ... there could be issues with the dealership that mattrush78 used inasmuch as their equipment could be uncalibrated, and therefore these tires balanced at that particular dealer on stock rims will never balance. I'm also hopeing that the others who have gone this route will speak up, as it currently appears that matt's problems are, while currently in the forefront of the discussion, still an isolated problem - comparatively speaking. imho

I am on my SECOND set of 235/45/17s on my stock rims!!! They are Toyo T1's, but you get the idea. I have had NO PROBLEMS what-so-ever!!!!!! No tire pressure problems, no traction problems, no rubbing problems AT ALL!!!!

JUST DO IT!!!

Slimey

It seems like a gave a pretty precise answer in the second thread.

Many people have mounted 235 series tires on the stock rims without an issue, but they will be out of spec.

If you want to stay in spec for the tire-rim then you are locked to the 215 or 225 series tires. Of course your odometer/speedometer will be off and the tires load rating may be off.

You decide. It's easy to look up tire specs online at either the manufacturer's site or tirerack.

When choosing an aftermarket tire, think about

I kept everything in spec with the aftermarket tire by upgrading my rims to 7.5" width. You'll find that if you want to maintain the odometer, maintain the load rating, and get a good tire, you'll be looking at 235 series tires on the 17" rim. Others have done the same on a 8" wide rim which can also safely mount a 235 series tire. There is really only one option that meet the stock standards/Acura's recommendation in the stock size, and that's the crappy OEM Michelins.

mattrush78

Two different shops checked the balance and rebalanced the tires. The 235/45/17 don't work will on the stock rim. What made me get the 225/45/17 was the fact the the 235/45/17 almost got me in a bad wreck! It maybe just a problem with the Acura chrome rims which I have. All I know for sure is that the 225/45/17 is a night and day differents. If only a couple of people are having problem it might just be the chrome rims?!?!?!

Slimey

Was the balance problem with all four tires, or an individual tire?

The question that needed to be answered is could that tire (the 235 series) be balanced on any wheel? I suspect there was an individual problem with the tire (or rim), rather then a problem with the size. Although I'm a proponent of the 235 series on a 7.5" or greater width rim, I cannot see why mounting such a tire on a 7" rim would give balance problems. As others said, it was probably just a bad tire...shit happens.

mattrush78

It was with all four tires! Two different shops tried to fix the balance problem! Like I said before it could be the acura chrome rim that have the problem. I don't know of many people with the acura chrome rim and the 235/45/17 tires!

The Sumitomo 215, 225, and 235 all have less Revs Per Mile than stock (stock is 819). The 235s are the closest. But I'm having trouble buying a thinner tire than stock. More miles on the odo and less cushion for the pot holes. A thinner tire does perform better...

Having a 235 work on the stock rim will depend on the brand, installer, the actual tires you have bought, and your rims. Not all 235/45/17 HTR Sumitomos are exactly the same from the factory.

yeah....i remember now....i was supposed to buy the 235 because they were closer to stock!!! Buy em'. I get yelled at by somebody on the board

MikeS 18

Oh, and I mean 2001 stock rims not 2003 stock rims...life was easier when our biggest problems were grungy wiper fluid and bad cup holders....

JRock

Stock rim width is only good for up to 225mm wide tires in general. Some people run 235s but that's their life at risk not mine. I would stick with what the rim is made for instead of being silly and trying to make the stock rim do something it's not meant to do.

AgentDSS

I had a thread a few weeks ago DEDICATED to the choice of either 225 or 235. Many said 235 is fine and the better choice. Only issue I was told was alignment, as it might be hard to attach the rim sensors.

I JUST (last week) had my Toyo T1-S proxies 235/45/17 mounted/balanced on my '03 Stock Rims and so far have ZERO problems. I was there at the installer the entire time and balancing was not an issue. 235 also keeps your speedo much more accurate than a 225 tire.

edgalang

BTW...I called Sumitomo up directly....and if/when you do decide to put them on, 36PSI is considered the low end. I have mine at 40PSI.

JRock

Yeah true, my 225s are off a whole 1.8%

Like an extra 18 miles every thousand is really gonna matter when I already have 48k on the odometer.

Even the 235s would be off some percentage so it's not like the difference b/w 225 and 235 is even worth mentioning, except when discussing safety and what the rim width is meant to handle tire-wise

Slimey

Well, it may not be a big issue, but it is worth mentioning.

The 225 series tire rolls at 834 rev/mile. It also has a load rating of 90.

The 235 series rolls at 823 rev/mile, the stock tire rolls at 819 rev/mile. That gives a difference of 0.49%, but YMMV.

Keep in mind also that the rollout numbers are for a specific measuring rim. The 225 was measured on a 7.5" tire, and the 235 was measured on a 8" wide rim. Rollouts on different rims may be different. The stock rollout spec was measured on a 7" rim, just like the stock rim.

Also as tires wear, their rollout/mile will increase. This percentage increase may be a little more in a tire that is already starting out too small to begin with.

These issues may all be negligible, but some like myself do consider this when purchasing. Personally, I'd like to keep my speedometer and odometer (and navi) as close to perfect as possible.

I did some speedometer and odometer checks after the upgrade to the 235 series tires and they are dead on accurate by stopwatch at three speeds and mileage markers. Good enough for me.

Not sure what your problem is, but I have stock chrome rims and I have NO PROBLEMS!!!!!

Now you're talking about 225mm in the same tire. I was talking about a 225mm tire that actually meets the load requirement, etc.

Slimey

Oops

Aztec,

I think probably the Toyos are okay - seems a couple of people have these with no issues; but it seems that the Sumi's are a 50/50 split between happy owners and unhappy owners.

AztecRol

iTrader: (2)

Well to be honest with ya, you are gonna get what you pay for. The Toyo's are a MUCH more expensive tire. So you are gonna get more quality, etc, etc. The sumi's are gonna be OK, but no where near the level of a Toyo. I'm not trying to be mean, but its the truth. Good luck with them!!

6speedctrlfreak

Aztec keep in mind that the OEM POS Michelins are $170 each...get what you pay for usually I've found in life so far yes this is true...but not with the stock CL-S Tires !!!!

Slimey

These tires shouldn't be compared. The Sumi HTR+ is an all season M+S rated tire. The Toyo T1S is a performance tire. Both are excellent tires in their class, but they are in different classes, and to compare them is unfair.

According to the clock on the wall, it's Wednesday. Did you put them on? Any problems? Fess up ... inquiring minds need to know!:thinking:

um....where are you located? Australia?

It's still Tuesday here in Mass.

CoolHandLuke

I have the Sumitomo's in size 225/45/17 and I think they are great I love the way they look compared to the stock tire. I almost get excited when I see the CL's at the dealer with those stock Michelins then I go to my car and it looks sportier just b/c of the tire design. But so far I'm a proud owner for over 10000 miles.

235s - NO problems
