Which one? You want me to email you a hi-res version? If so, name the pic and what resolution you want. I only uploaded 640X480, and we can certainly do better than that.

I am buncing my wall paper between the 2 interior shots.

my monitor is kinda crappy so low res will do just fine..

WesAllen, welcome.

I have a 1994 Q. I bought some 17" rims (Konig Diva)off of eBay, and have put several sets of different tires on the car.

I started out with a set of used Bridgestone Potenza RE92 225/50/17. The load rating was not rated for the Q, but the tires worked great. They are expensive.

Then I went to a set of used Contonental Sport Contact 245/45/17. Was not happy with ride quality. The inner sidewals are actually softer, and is not good for the camber of the Q. Burned up the set REALLY fast.

The third set was a set of new NITTO NT455 225/50/17. Directional tread was a little noisier, and the load rating is still a little light for the Q. Great tire wear, much longer than expected. Great wet and dry traction. Tires needed to be balanced every rotation. Great price.

The set I have now, is Sumitomo HTR+ 255/45/17 on the rear (just bought), and 2 of the NITTO's on the front.The tires are just the right width in the rear (requires an 8" wheel), but I am torn whether to keep the narrower tire up front. I rotate every month (5,000 miles), and this extends the life of the tires, but if I don't keep the same size tires all the way around, I will not be able to do this. I will probably stick with the same size all the way around

My car is stock ride height, and stock struts. I plant to install the Eibach springs and Tokiko Blue's, this winter.

I hope this helps.

I have al ink in my signature for a photo albumn of my car.

I am thinking about putting 17inch wheels on my 94q, but am concerned about any possible negative results of doing so.

Could those knowledgeable in these types of things please give me some advice.

Thank you in advance

Welcome Wes. My 2 cents: I have a 94 Q with 245/40/18-18x7.5 rims. There is minimal affect in ride, increase in handling. Only problem is that in messed up cities like NY you have to slalom like a olympic skier from the craters they call potholes. I have driven long distance from NY to ATL and the ride is still great due to the wonderful, ahead of it's time suspension. 17's would be great for you. Minimal but reasonable change in ride, but makes for a better looking vehicle. I could never understand why dealers used to place a two ton car on 15's. That's like a sumo wrestler on ice skates! They're learning though:thinker

[WesAllen]

Thanks again for all the info...on another topic, I need to replace the passenger side fender for my car and am wondering if anyone has any info on where I would be able to obtain one for a reasonable price, whether in the NYC area or otherwise.

You can always flip them side to side, just like you would have to do with directional tire or wheel. Of ocurse, as Q45tech has stated so often, most of the stress on a Q45 is on the front anyway, so you do want to match the highest load carrying capacity there anyway.

Your car is hot Jeff. Hot color!

THANKS! I thinks so, too. I am truely blessed to be driving such a nice car.

In the back of my mind, I want to get my hands on some 18" M45 polished aluminum or chrome plated wheels, but I will need to wait another year, since I just bought new tires. I won't pass up a sweetheart deal on eBay, though....

[OLU40]

I have 18's on mine. They were up but I cant find the updated pictures with the chrome. I'll post sometime this week for you to see.

In the back of my mind, I want to get my hands on some 18" M45 polished aluminum or chrome plated wheels.

There is one issue I have with the OEM M45 wheels: they are only 7.5" wide. This restricts maximum width of tires to 235/45-18 (terrible selection of available tires) or 245/45-18 (somewhat better selection). Very poor choice! Infiniti should have put 8.0" or 8.5" rims on this car!

[NY94J30]

It seems Infiniti has a tendency to go narrow - J is 15 x6 OEM - for the sake of EPA mpg ratings.

On a brighter note, I just upgraded to 17 x 8 (235/45/17 Falken Ziex)

On a Q, a better fit would be with the 245/45-17 for Falken Ziex - this is a close match on the rolling diameter to the OEM tire (size is 215/65-15). Makes for a close match on the speedometer.

What is the stock tire/rim on a J? If the same as the Q, then the 245/45-17 may be a better size for you too! And these will fit on 17x8 just fine (minimum rim would be 17x7.5).

Z

[NY94J30]

OEM was 215/60/15 for the J on a 15x6 rim - I was told that the 235/45/17 was cloesest to stock diameter

[NY94J30]

Just did the calculations - oem 215/60/15 has a diameter of 25.157 in, while the 235 I just put on has a diameter of 25.326, giving a speedo variance of +.6% (nominal). The 245 would give a +2% variance (not bad, 51mph @ 50mph) and a 255 would give +3.5%.

The change from oem to a 245/45/17 on the Q gives you a -1.25% variance, and a 255 gives you +.12% - So the 255 is actually closer to oem diameter

Good info!

In addition, here is some information I gathered for a Q45 when I was researching tires some months back. if you save this as a "CSV" file, you will be able to read it into Excel. So, it is not easy to read this - if anyone wants to see the original Excel file, please send me e-mail.

FWIW, it is not complete, either ... I was focusing on 17" tires (since I had G35 rims) and the 15" tires (since I had the original Q45 rims). Also focused on tires that would fit a 7.5 or 8.0 rim. So 16" tires got a bit of a short shrift.

Note that I made sure that the tires were 95 load index or higher only ... to make sure that the Q did not overload them!

By the way, it is important to note that diameter of the tire is not the best way to calculate the speedo error. This is because the diameter calculations do not take into account the sidewall flex of softer tires, etc. The effective rolling diameter can be different. Hence it is more accurate to use the "revs per mile" provided in some tire data to estimate the speedo error. In my text above, I use the revs/mile, unless it is not available - then I use the diameters.

The front gets a harder workout? Hmm. From my experience the rears get chewed up very quickly.

I am sure yours are from burnouts. Mine do too, but not for the same reason. I typically do not drive hard in the corners, and with the Independent Rear Suspension, the camber is set a little negative for hard cornering. When the car goes into the corner, the inside suspension extends, and the camber goes neutral, and the outside suspension contracts, making the camber neutral, as well. If the car does not do much hard cornering, the inside edge of the tires gets more wear. I spend 99% of my driving on the interstate, and that is why I had to replace 2 tires, and will replace the other 2 in a month, in my opinion.

[OLU40]

I wish mine were a little wider too. I'm at 7.5 x18. 8 or 8.5 would look alot better.

Replica wheels for that price would be of great concern - I certainly would not buy them. I would much rather get G35 wheels or M45 wheels to fit the Q - they do show up occasionally on eBay. The size of this replica is the same as the OEM M45 size, by the way.

Jeez, I totally missed the word "replica" in the ad. Focusing on the picture, they look identical to wheels on my M45. Guess I never looked that close but I didn't think the current Q and M used identical wheels. Very close, but I was thinking that they were slightly different visually. Are the Q and M 18" wheels actually the same?

On a side note, I briefly brutalized my Turanzas today. There's a never completed industrial development behind the row of dealerships in my area. Never gets any normal traffic, but is a popular spot for dealer demo drives. Lot's of black donught marks on the pavement throughout the non-developed development. I had just paid a visit to my dealership, and felt like blowing off a little steam and thought I might contribute to the asphalt artwork. Turned off the VDC, cranked the wheel and did a very smokey 360. Turns out that when you do such nonsense, the ECM becomes convinced that something horrible has gone wrong with the VDC system and and a huge warning appears on the LCD display to contact your nearset Infininti dealer immediately! Fortunately, turning off the car and restarting it does a reset of some sort and the message disappears.

At the moment I'm leaning toward the 245/45-18 Michelin Sport A/S as replacements. Pricey, but I like the 400 treadwear rating. Had them on my prior Q and liked them. Still looking forward to your findings, however. Won't have to make a choice till first or second quarter of next year, I suspect.
