This question was originally posted on the wheels and tires forum, but im not getting much luck for an answer.. Also, im running out of time to make the decesion.. here is the all the information i have:

i have a 96 max, with 18's, lowered on h&r's. ive previously had, without issue, 18's on there with a 245/40/18 toyo's , i currently have 235/40/18 on the car now.
i am in the market for new rims and tires, and would like to step up the tire size to a 45 series. the rims i want are 18 x 7.5 , with a 38mm offset (murano rims). the tires i want to put on them are Falken Azenis st-115's , size 245/45/18.. they dont make a 235, or a 225 45 series in an 18. the overall diameter of the tire is 26.7, section width is 9.4 .

so.. im sure your know what im about to ask next.. will these rims, with those tires, fit on my car without rubbing? if so, can i get spacers to correct this? or is this just not going to work at all?? these new tires are only 1" total , taller than my old ones, so its only a 1/2" difference on all sides in the wheel well..

ive seen people refer to this same set up on here, but only on 5th generations. ive been looking and questions for days, and tried to find as much info as i could, but ive now hit a rut and i need somebodys help!!!!!

 

From all my readings in the forum, the maximum is 235/40-18 tires, optimally without affecting your speedometer.

Also check the stickies in the tires/wheels forum, there are two wheel calculators there. Between the wheel offset & tire calculator, you should be able to answer your own question. Get off your ****, measure the depth of your wheel well and compare that with the result in the wheel offset calc. Same thing with the height between the ground and the wheel well, compare that with the height of the new tire size.

Your not getting much help because there are enough tools to help yourself.

 

The offset is fine, but the wheels should be a little wider for 245's. If you're going to have 7.5" wide, go with 235/40s.

 

yeah 7.5" wheels can only handle 235 max. If you want 245's you'd have to have 8.0" wheels on there at least.

 

i would rather go with a 235, but they dont make any tires i want in that size. also, i want to go with a 245/45.. not a 40, that is why my tire choices are limited. i know it would be better to have a 235, but the tires are approved for 7.5 rims, and plenty of people run that size on here without issue


i know for a fact that these rims will fit without issue with 245/40/18's on them. someone else on the forum just put them on his car ..

my question is, will there be any issues or rubbing the strut tower?? or my fender digging into my tire if im going around a turn??? just because of the small differnce in height between the 40 thats on there, and the 45 i WANNA put on there. put it this way.. i dont know what to even look out for in terms of there being any issues .. i thought i might ask in here to see if anyone else has, or had, these size tires on a lowered car, and then take it from there

 

245/40/18's, will definately fit on the car without issue. i know because i already had those.. as far as my speedometer goes, honestly i dotn even care about that.
ive checked the stickies, i know theres an offset and tire calculator. ive been looking at tires for says now, along with reading every post in that forum, with the hopes of stumbling across someone running 18's, with the same tire size i wanna use, on a 4th gen with a slight drop.. no luck.. all do respect, its kinda of hard for me to measure in millimeters to see if my wheels are gonna rub if i hit a bump, or if the front fender is gonna dig into my tire if im going around a a hard turn. belive me, im not being lazy, im being smart.. im not about to spend over $1,000 to experiment and see if my measurements in millimeters was accurate or not. im much better off trying to find someone that may already have this.. but thank you anyway

 

Again, the answer is in the stickies under "wheel offset calculator". Plug in the current wheel size and offset, then plug in the new wheel size and offset and it will tell you if you'll clear the strut housing and wheel well (if the outer edge of the wheel will stay the same or stick out more). Like I said before, its all in the stickies. Just use it!

Well if the 245's fit on those wheels, then go for it, I wouldn't do it because it's not recommend and it might look a little funny.

And if you go with a 245/45, that's fine too, that will look like the 04+ Maxima, which is good for that car, but might look a bit to tall for your 95, but again, to each his own.

There was a guy on here a long time ago from Hawaii and he had 255/(not sure) 20's and they fit fine even when lowered, so I wouldnt be worried as these will be taller than your stock height.

Smartest and safest thing to do is get the offset of the wheel, measure the offset relative to your hub, measure height and width of the tires and decide if they will fit or not.

 

seriously, i understand what you are trying to show me .. what i am trying to tell you, is that you are mis-understanding my question all together, and insist on trying to make cracks instead .. the rims i want, and the offset.. HAVE NOTHING TO DO WITH MY QUESTION. 245/40/18 TIRES fit on my car without problems.. they fit on those rims without problems. they fit on the rim, on the car , without problems.. BUT .... will a 245/45/18 TIRE fit on the LOWERED car without RUBBING.. the rims fit perfectly fine. i know that much .. i dont know if the TIRES will without rubbing against anything cause the cars lowered...

 

im pretty sure they'd fit on the car.. but i dunno what gonna happen when i drive? when there's 2 people sitting in the backseat? when im going around a hard turn, and hit a pot hole.. ya know.. as the wheel is turned, and i hit a bump, if the fender gonna come down on the top of the tire i just bought and start shredding the edges?
i know the car your talking about i think.. it was white, chrome rims.. but if im thinking about this rite, he could of had those 20's in there, with a 30 series, and still have the same over all diamater as someone with 245/40/18.. am i wrong?

 

I give up! Someone spoon-feed him!

FYI, offset has everything to do when it comes to clearing the wheel well and struts! On a lowered vehicle, doesn't it make sense to do a little bit of your own calculations using the tire/size calculator? That will figure out your overall whee/tire height. Compare that to what you come up with when you measure the distance from the wheel well to the ground, allow maybe a few inches of play or more (with more load inside the car - give it your best guestimate) when your suspension rebounds as you hit dips and bumps. 1" is 25.4mm. Now do the math!

Im not trying to take cracks at you, just trying to steer you to the right directions but seems like you prefer to be spoon-fed. I've tried that before and the org has almost zero tolerance to that.

 

Can I just say a few things? I want to bring-up the plus one concept.

205/65-15 = 215/55-16 = 235/45-17 = 235/40-18

I can't tell you if 245 or 235/35-19 is the right fit, without looking it up.

You want 45-series, go to a 17" rim. You don't just say I want 45-series and it has to be 18", and can I go to 245/45-18. Not only are you going wider than the correct fittment for 18", you are also going taller. So 245/45-18 has two strikes against it.

Whenever you change the tire width, you want the overall diameter to be identical. Identical means the equivalent according to the plus one concept. When you go from a 15" to an 18" rim, you gain 3" of rim. You take away 3" of sidewall, and the overall diameter is the same. It really isn't arbitrary at all. A good tire shop isn't going to mount a 245/45-18 on a 7.5" rim and then onto your car--they'll explain plus one to you.

 

i understand you.. but if the tire fits rite at the edge "inside the wheel well" when its straight, now if turn it, it doesnt.. how far away is it when its turned from the fender? from the wheel well on the opposite side. when it hits a bump? there is no way im going to be able to acurately figure it all out without just putting it on the car.. i cannot build an imaginary rim and tire with levels, t-squares, and tape measures, and then turn it back and forth, and then jump up and down on my car to see if anyting is going to hit or rub. if anyone was able to, when we are pushing the limits on what we can stuff under there, nobody would be asking questions like this. if you visit the tire forum, you will easily see i am not the only one asking a question like this, and this is probably the most difficult out of the ones that are posted.. as a stated before, i dont want to spend over $1,000 on my "best guestimate" im trying to see if anyone has the same set up, or if they tried it and it didnt work. i'd like to hear from someone that has experienced this, first hand , and is willing to pass there experience on, just like every other person asking a question on here.. if i could accuratly do it myself, i would. if i could find the answer by looking it up, i wouldnt be here like i am now.. ive gone as far as i can on my own. thats why im asking other members, and why many other members are asking questions too..

 

Bingo!!! You will probably run into one or two or none in the org running the same size tires your inquiring about simply because 1) it's not within the plus-one concept 2) not available or very rare if any. Common sense should dictate that its not a good idea. If you want to be the first one to run this size and become the guinea pig, then this is your time to step up. But you might not get there w/o a hitch. The reason I'm trying to point you to that direction is to let you realize on your own that the size you posted is probably a bad idea. As Frank Fontaine already said, you got 2 strikes against running that odd of a tire size. That's another hint! I've never ran 18" wheels before, but plus sizing is adaptable to the size of wheel your going up on. 20" wheels on a Max is just simply ridiculous and dangerous.

Anyhow, good luck!

 

its almost the same tires size that comes factory from nissan with the 6th gens. factory tires from them, are 235/45/18. the one i want, is for the the most part, just a little bit wider 245/45/18. i wouldnt consider it a rare size, but only for performance tires as there are many all seasons, and winter tires. falken also approves that tire for a 7.5 inch rim. just as a 235/40/19 might be considered rare.. not many people make it, becuase its not the "commly desired look". but in that case, is much better than the 35 series if you dont want to bend you rims and have a better/safer ride. i mean, are you saying that if i had a 05 max with stock 18's, and out a 245/45/18 on it, it wouldnt be safe? the murano rims i want come stock with 235/65/18.. the plus one factor your talking about, applies mainly to keep the same diameter as the stock tires, mainly to keep the speedomoter correct. i dont care about the speedometer. i care about trying to keep 18's on my car and not bend a 3rd set cause the 40 series on my last two sets killed them.

if you type in 245/45/18, on a search on tirerack.com , they have over 43 different tires available.. not including, falken, nitto, or toyo

 

Looks like I'm the only one left still bothering to help so this is my last reply. Your car isn't a 6th gen! Different car and different capability.

 

ok.. i appreciate the help, but i dont want to turn my tires into the discovery space shuttle.. i know, driving a 96 maxima, with a 245/45/18's on it should have me commited, and anyone driving on 20's is suicidal.. i cant see how adding a 1/2 inch to my sidewall is going to put my life at risk, and the rare 50+ tires they make in that size should be listed as dangerous and boycotted even though they are approved for the rim size i mention. they must all be made as replacement tires for 6th gen max's only and on any other car they are no good. weather anyone has an 18x7 , 18x7.5, 18x8. 18x8.5, 18x9, 18x9.5, any form of 19's or 20's, everyone is driving on the wrong size tire. ill take my chances..

anyway.. does anyone out here have the set up i mentioned in the begining of this post? or has anyone had it in the past and suffered complications of rubbing? thank you...

 

bump.......

 

and again.....
