im planning to purchase new rims for my type s. the wheels i want is moda r6 with potenza re730 225/45/17, that's what the local shop recommend. i call tire rack yesterday to check on the price and they say they don't recommend that tire size cuz it will rubb and they will not guarantee anything. so im not sure what to do now, anyone have any suggestion?? thanks in advance..

Tire Rack told me the same thing. I went with Toyo T1S Proxies in 235/45ZR17 on my stock wheels. The RE-730s are excellent tires *and* will really help in the dry and wet.

If you are concerned, find a local dealer that will work something out with you (as follows):

1. Have them mount two tires on the "new" wheels.

2. Remove two of the stock tire/wheel combos from the front driver and rear driver side.

3. Gently place the new tire/wheel combos in place (they did mine on jacks/floor lifts 1st). You and the dealer should check for clearance between the suspension and the wheel. If you have to, get your finger in there and feel for how much room.

4. Have the car gently lowered with the floor jack and check for clearance as you lower it.

5. If you really want to be sure of the fit, get in the car with 3 helpers and see if there is any rubbing in the back.

Yes, this is a hassle, and someone here will probably give you a wheel/tire combo that works OK. My Toyo T1S 235/45ZR17s on stock wheels never rub. Some of the folks with other tires and wheels get a little rub in the rear fender area when they have more than 2 people in the car *and* are lowered.

Ask around or at least check the search engine for:

225
235
wheels
rubbing
...
...
etc


Good luck

Have you asked them about a width of 235 instead of 225. If memory serves a 45 series, 17" tire is closer to stock than 225.
Might at first sound nuts but upon using one of those handy wheel size calculator things found some places online that size is closer than 225 width. Again if I'm not wrong that is

Good luck …

they stated that they only recommend 215/50/17. im aware that using 225/45/17 would throw off the speed a little and im ok with it. i'll just get the car recalibrated. since some people on this forum has 235/45/17 on and stated that the tires doesn't rubb so i would figure that 225 should be fine since its smaller then 235?? does that make sense??

Some thoughts....

1. Add a new topic that asks for comments from users running 225/45x17 or 225/40x18.

See what they say about the slightly lowered radius. Given the exact same make of tire, a 215/50x17 will be have the same rolling radius of a 238/45x17" tire.

I didn't ask the other users who are running 225s how they worked out. I just didn't like the stock rubber on new pavement, wet concrete, at speed in water.

Tire rack has to cover their rears. Hard to blame them after the Firestone/Explorer debacle!

They will send you a set of what you want, but you better make sure they fit.

They said that they would put wheels and tires together and then send them to a "qualified" installer. They said they would accept a return if it didn't work.

Some of my concerns (I can't tell you if they are valid or not, they are mine and only mine):

1. Acura Care didn't like the change in rolling radius vis-a-vis the VSA *and* NAVI (they said it, I didn't). Who knows, maybe they have changed their minds...

2. Tires from different makers have different unloaded diameters, section widths, and tread widths for a given rating.

For example: think 225/45x17 is the same -- look through all the spec. sheets on Tire Rack's web site. Check out the all season, then the max performance, ultra high performance tires. The tires will have different tread widths, section widths, loaded radius, and rolling rpms for a given size!

The safest bet to match rolling speed, is to put 235/45-17s on stock wheels.

When you move to wider wheel, each different make of tire will have a different "section width". Check out the following link:

http://www.tirerack.com/tires/tirete...l#sectionwidth

The tire's section width (which will effect the rubbing) is also dependent on the wheel width. Please keep this in mind.

So, try to find someone with something that works, and get that setup *or* use that as a starting point to get something very close (Just my opinion)...

"1. Acura Care didn't like the change in rolling radius vis-a-vis the VSA *and* NAVI (they said it, I didn't)."

what does that mean?? i thought the navi is using the satilite, it doesn't matter what the speedometer says or what the rolling radius is. anyways, thanks for ur input.

I have the potenza RE730's in 225/45/17 and they are awesome, great handling, no rubbing and great price. I also have the Comptech springs.

The NAVI *does* use satellites. However, it does "loose" them. When the car is in a tunnel, around tall buildings, or there is a ton of solar radiation, the satellites will "disappear". There have been a few radiation storms lately *and* I've lost all the sky satellites for more than 1 hour. With my Toyo's (235/45ZR17s) I was only off by a few feet after losing the "birds" for over an hour.

When the satellites "disappear", the Alpine/Acura navigation system relies on an internal gyro. There are also wheel sensors. The question is:

Does the NAVI compare the number of tire rotations (presuming a given size tire) against the internal gyro? I haven't gotten an answer on this. However, there is a special diagnostics mode that the NAVI system can be put in *and* one of the options referred to "Tire Calibrate"


See the following link:

http://www.acura-cl.com/ubb/Forum1/HTML/000150.html


So, if your car doesn't have NAVI, don't worry about it. If you really want to be safe, ask a member with the 225s and see if they have NAVI and use the VSA. If it works and they are happy, then all is well.


Finally, I was looking through the messages and someone said that they were running 39 lbs of pressure in a 225 or 235 and the tire was rated for 40 or 41 psi max. THIS IS NOT A SAFE situation!!!!

Tires get hot and the pressure rises during normal driving (even more at high speeds). XL tires like the Michelin OEM tires and the Toyos designated with a "*" (for reinforced carcass) will withstand a lot more pressure due to the XL rating. I run my tires at 39 psi, but the tires have a max rating of 51lbs (BTW -- the toyo.com page is wrong about the max pressures on a lot of the tires).

Please be safe. The tires will get warm at speed *and* even though the RE-730s and other high performance tires are well made, they are not designed to run beyond their rated pressure. So whoever mentioned running their tires at 39 lbs with a 40/41 max rating -- please take care and don't drive at high speeds for extended periods regardless of the ZR rating!!!!

Tirerack will always call you back anytime they find that the car you listed and the items you wanted to buy are different than stock specs. I'm sure they just want to make sure idiots don't buy stuff, put it on, find out it doesn't work and then try to send it back. They did the same thing when I bought my Konis that are supposed to be for the TL.

They are quite willing to let you try the wheel/tire packages out (if you pay the shipping fee). They were quite nice that way. I just wanted to try things out in person at a local dealer. They also go on and on about the stock tires, XL rating, etc.

Go to their site, and look up the "Popular tires" for the CL-S.

Then look up popular tire sizes, etc for other cars.

I was just looking for some new rubber for my wife's '95 Altima *and* there are a bunch of suggestions. For the CL-S, there is only a single listing with the stock MXM4!

I was told by Tire Rack rep recently that the Dunlop SP Sport 5000 is available in the original CLS size. It's priced at $ 194, but I am sure the price will go down. The test data is available on Tire Rack tire test page. The report is excellent. My friend bought 4 for his 1999 Avalon and he is crazy about the performance. Check it out.

Preface:

If your are suggesting that I will consider the 5000s for my wifes Altima -- thanks.

I am probably going to get my wife's Altima some Yokama ABS db decibels. However, the 5000s are in the running... (She had 15" wheels *and* doesn't want me to change the wheels to 16"/17" alloys.)

BTW -- I did not suggest that there were no other tires in a 215/50 x 17 size. I just said that Tire Rack's "View Best Sellers" only shows the OEM MXM4s, unlike other cars. If you look for tires in a 215/50 x 17" size, you will see there are a few, but they are not:

1. XL rated
2. Higher than or equal to the OEM's 93 load rating.

I could go on but, that's enough...
