You may have to fight with your tire shop to get this done. The maximum recommended tire width with 45 series tires on the stock 7" rim is 225. There are numerous threads on this and some opposing views so try the search function.

I read the FAQ's but am just a bit scared. The FAQ's read:
A number of org members run 235/45R17 and 245/45R17 tires on their OEM rims. Those who run these tires generally do so because of the much wider selection of high-performance tires available in these sizes. Unfortunately, no tire manufacturer will authorize the use of these tire sizes on 7.0"-wide rims. To date, however, no incidences of tire failure have been reported as a result of running these sizes on the OEM rims.

235/45R17: This tire size is NOT in spec on 7.0"-wide rims. (The minimum acceptable rim width for this tire size is 7.5".) It produces a speedometer error of 2.1%, well within the recommended maximum speedometer error of 3.0%. Load ratings for this tire will normally equal or exceed that of the 225/50R17 (load rating 93) and should not be a factor in selecting tires of this size. Watch for abnormal wear characteristics if you select a tire in this size.


Can any other org members chime in with their experiences???

Thanks for the prompt reply hombre

Just give the guys at TireRack.com a call, they will let you know what sizes are within the 3% for the Maxima. I was told that the only other safe size for the 7 inch rim 17 inch tire was 235/50/17. Any other sizes on the Nissan Rim would be over 3% and throw the speedometer quite a bit.

i have yokohama and kumhos that are 235/45/17 and they seem to be fine. they've lasted for the last 5k miles and it still seems to be workin fine. no unusual wear and stuff that i've noticed...

FWIW: Can't speak "with experience" because I'm in research/purchase mode myself. I can say this.

1. I too am staying on stock 17" x 7JJs by choice.
2. I have run the calculator ad naseum (great tool)
3. I am staying with 225/5X-17's.

The only decision for me yet, 50's versus 55's (225/55-17’s calculate to +1.6% and 225/50-17’s calculate to -1.7%, both within accepted tolerance)

Well it just sucks cause the tires I want I cannot get in the OEM size

Another FWIW....I too would like to stay with the stock wheels, and have heard good things about the Sumitomo HTR+'s. Naturally they do not come in the factory size, and not really sure I want to spend the $$$ for the Pilots. I decided to write Sumitomo and ask if there are plans to add the factory size for us. He did mention that it would happend, eventually, but could take another 9+ months. I guess the reason for this is that an agreement was made with Nissan and only a few tire companies...so that Nissan can buy them for dirt cheap initially to install for their new models! That might not be the exact or best explanation...but that's it in a nutshell. So maybe in the near future, we will start seeing a better selection from others as well. He did also mention they do not recommend the 234x45/17 for the Max's factory wheel.

Ugh that sucks because the ones I want are affordable and look good and can handle snow. Everything else sucks *** and now I am freaked out about trying the 235/45 on stock rims.

One thing I dont get is that the 234/50's fit but the 45's dont. Why is that its just sidewall height.

Hope you don't mind me askin this ? in your thread Fuel, I don't feel like startin a new thread for a dumb ques. like this one though :

W/225/45/17 the speedo error is like 3.5%. Does this affect only the speed measurement or will it have an effect on the miles recorded on the odometer also?

A couple of comments, I've been running Dunlop SP5000 tires for about 20k in the 235/45/17 size. Looking at the top of the mounted tire, the tread is "curved" from the outer sidewall to the inner sidewall at about 34PSI. If I drop the air pressure, the curvature goes away, but the handling gets "squishy". I will not use 235/45 again.

Besides 225/50, you could consider 235/50 and 215/55 (stock size on certain 2K3 with 17" rims).

235/45/17 will work fine I have AutoX'ed on my Potenza RE950's on OEM rims for a season and a half running 50psi+ at times and have had NO problems at all. If this kind of torture didn't break them a littke sprited street driving will be a walk in the park.
