anyone have this setup on their tire.

currently i'm on 245/45-18's and i've learned that 245's are just WAY TOO WIDE for my 2k2. i'm on 04 SE 18's and i rub even with no one in the car. this may have to do with my really heavy sub-box (1" plexiglass).

as i was doing my research, it seems that Falken 912's seems to be a moderately priced favorite, so i was leaning towards them. i chose 235 because i wanted something thinner to avoid rubbing

initially, i was looking at 235/40-18's, unfortunately, this drops down my sidewall height a full 0.7" (i'm comparing to my stock 225/50-17's) and to me this is important because i'm in NY and these rough roads can really do a number on your wheels, plus i'm looking more towards the comfort so i want a meaty tire.

now, falken doesn't make a 235/45 for the 912's so i looked at 225/45's and they do make them ($111 @ vulcantire). i checked the sidewall height and it comes out to 0.4" shorter than the stock 17's. that's still better than 0.7 on the 235/40's.

this is where i ask you guys. any opinions on this setup? does anyone anything like this. if you have 235/40's or 225/45's, please let me know what your thoughts are. again, i'm going for comfort over looks as i'm in NY and i'm kinda over the whole looks thing. i'm happy with my 18's and my system and just want to enjoy the ride.

thanks all.

 

How bad is it? Rolling your fenders an option? What offset are your wheels?

225 is too narrow on an 18 in my opinion.

 

rolling fenders not an option. again, i'm not about hookin this car up anymore. i have my system, i have my bodykit, i just want to enjoy the car now. NYC streets suck, plain and simple, and i just want to be able to drive with no concerns. 235's would definitely avoid the rubbing, but then i'd have to get 40 series tires. question is whether that would be too thin of a sidewall. if i got at least 45 series tires, then i'd be forced to get 225's. Rather, i'd be forced if i were only to get the Falken 912's, which at the price, is what i'm leaning towards.

I have 245-40-18 on 8.5" wide wheels, +33 + 15mm spacers (effectively 18mm offset), and 5mm up front (+28mm) and Progress drop in the rear, S-Tech up front and only rub on 1 side in the rear due to my beam being 'un' centered.

 

yeah, that's the rubbing i get.
and i don't want that.
i need new tires anyway, so i might as well get something a bit thinner than 245's.

 

Don't be a woose, rolling your fenders takes literally like 15 mins per side....

 

I'd re-center the rear beam (I also haven't done this and rub on the rear-right). I ran 225/45/18 Michelin Pilot Sports AS and never had a problem on my G wheels (18 x 8). Now I've got 235/40/18 General Exclaim UHP's and am MUCH happier!

 

I've been on 8" wide both 30mm and 25mm offset/245's and wouldn't ever rub, not sure why you guys are.

 

already tried re-centering. go into that thread. you'll see that it doesn't work as people thought.

but it sounds like you have and had exactly what my dilemma is about. what makes you happier about the 235/40's? the way i see it, the 225/45's will be a bit thicker (7mm to be exact) and give me more cushion. or is it negligible at that point.

 

could be the type of rim that doesn't have a big offset and you can go wide with no problems. whatever the case is, i rub, as do *numerous* others.

besides my system, i have my bicycle as well as a few people that go in the back on the norm, so my rear is already pretty low once it fills up.

 

I ran 225/40/18" and those were too small and couldn't handle the weight of the vehicle. 225/45 might work better, just make sure it's rated to handle the Max, weight-wise. Although, i think you're better off with the 235's.

I suggest trying on the 235's first, go to Goodyear or get hold of a Toyo and take them up on their 30 day/ 300 mile test-drive offer. It might help you determine the best size to use.

 

Rolling fenders != hooking up.

It alleviates the exact problem you are having while not going to a tiny width. Thanks for listing wheel specs by the way. 245 is NOT too big for a 5th gen by any means.

 

It's not definitive. No one ever followed up meaning he may or may not have done it correctly. Again, no definitive answer. I'm guessing you also tried this with no success?

I already mentioned my offsets & widths, and they are similar to yours and everyone else that rubs, in fact mine are lower, and my wheels are wider meaning even more of a chance to rub.


. . .

these aren't Civics. Not much sidewall AT ALL.

 

the stock width of a 17" SE tire is 8.85 and the stock width of an 18" tire is 9.64. i think it is too wide. look at the fact that a large number of people with 245's are having rubbing issues. or to put it precisely, members with 6th gen maxima wheels with 245's are having rubbing issues. i don't plan on changing the wheel and i need new tires as mine are done.

 

What you *think* and what fits are two different things. It seems like you have your mind made up about this anyway. Also different brands/models have slightly different widths so that number is bearing on irrelevant.

 

my mind is set on either of the 2 tire choices.

when i say think, i state that simply because i'm not an expert, but when you read up that every 5th gen member with 6th gen wheels/tires rubs, then i'm pretty confident that 245/45 on that wheel is a problem.

 

we went over this before man. I ran 245/40-18s on the same rims as you..NO rubbing. Perfect tire size imo. Trust me, I did LOTS of research before picking those sizes out.

edit: you can always go to a tire store and have them test fit the tire on the rim and then on the car to see if it will be problematic

 

You see what was done here?

It's the 45 aspect ratio that is the problem, don't blame the 6th gen wheel, blame the 6th gen tire.

245/40-18 > *

Learn to use the wheel/tire calculator provided in the stickys.

 

and i do agree with you, i do blame the 6th gen tire. if i were to blame the 6th gen wheel, i wouldnt' be asking about what tire to use.

please don't try to belittle me by telling me to learn how to use the tire calculator. i know how to and i have read up on them. plus, 1 of the links in the sticky's is dead and the other just sucks. 1010tires has a FAR BETTER calculator and comparison.

and to add, one member claims that his 245/40's worked. that's one member. as much as i'd like to take his word (and i've talked to him on the side in the past), i cant' take one users opinion. i'd have to hear others chime in with the same setup and their opinion on the matter.

 

according to the tire calculator 245/40 is the only size that will make the speedo as accurate as possible. I know a few 5th gen members had that same size on their 6th gen rims too. Thats why I ultimately came to the decision to get them. I do agree however that 225 will be too narrow

 

Well, i do have 245/40/18's now on 8.5" width rims with a 40mm offset. No rubbing at all even with the car loaded.

By the way, try this calculator. It helped me a while back as it also calculated clearance both on the inner and outer side of the rim.

http://www.rims-n-tires.com/rt_specs.jsp

 

A34 18" wheel = 45mm offset, 7.5" width
My 18" wheel = 33 offset (add my 15mm spacer, you get 18mm offset), 8.5" width.

There can't be much difference in the wheel design that would make it stick out THAT much more (+40/7.5 vs +18/8.5). But like Freeway said, you're set on that tire size, so

 

fair enough.
calculations show that the 245/40, compared to my current tire, is going to keep the same section width, with a sidewall height reduction from 4.3 to 3.85.

i guess my problem here is if i am rubbing on 245/45's, how will i NOT rub on 245/40's. are we saying the lower sidewall is enough that when the car dips and the tires slant in, i'll avoid bumping the fender?

 

Tires a little shorter, plain and simple.

As far as sidewall flex etc, that's tire specific.

 

after much thought and discussion with my voice of reason (good friend of mine), i'm going with 245/40's.....if i rub, i'm shooting everyone in this thread.

as an fyi, these are pictures of my current height. no one in the car, just a very heavy system and stock springs with tok blues.



more pictures here. i don't want to swamp this thread.

My car is the same height as yours in the rear. I run 18x9.5 38 offset and 265 35 18. No rubbing except on BIG dips. This is only rubbing on fender lip that could be fixed with a fender roll (my beam is also off centered too) it happens so rarely that it's not important. I definitely think the 45 series tires are killing you. 245 40 18 is perfect... only reason I am running 35 series on the back is due to the width 265 and the 35 series gets specs in line perfectly (i run 245 40 18 on the front 18x8.5)

 

Marco, 235/40 or 245/40 should both be fine.

Have you shaved that little inside "lip" where the fender meets the top of the bumper? You can shave it down about 1/2" with no problem. It is probably where you're rubbing.

 

^ I'm thinking that's exactly what I'm going to do, once this hell called "final exams" is over with.

 

I've been running on 245/40/18s for 1+ year and no rubbing at all unless I have people in the car. I also have a system in my car. It also depends on what type of suspension you are on as well.

 

So whats the final word on the optimal sizing for a 5th gen?


I am (will) dropped with Illuminas and progress.. and I will be getting next spring a set of Sportmax:

Size: 18x8.5
PCD: 5x114.3
ET: 35 (is this the offset? otherwise I dont have it)


And a set of General Exclaim UHP... and they are offered in the following sizes:


235/40ZR18
Load Index 91 = 1356lbs (615kg) per tire
Diameter: 25.4"

245/40ZR18
Load Index 93 = 1433lbs (650kg) per tire
Diameter: 25.7"

245/45ZR18
Load Index 100 = 1764lbs (800kg) per tire
Diameter: 26.7"

Stock 225/50-17
Width: 8.85"
Sidewall: 4.42 in
Overall Diameter: 25.85 in


In this case, General do offer the UHP in 235/40. So which is more suitable?
