205/40/17 to small on 2g?

[bigbro6785]

Do you think 17" rims with 205/40/17 tires would look to small on a 2g (lowered on sportlines)? My tires are shot on my car on the stock rims, and my friend offered to sell me a set of rims and tires that he uses to have on his car for $400. The rims and tires have maybe 6 months of use on them (RS Limited Ricochet Rims and yokohama tires), then he decided to go back to his stock rsx rims. I was gonna trade my stocks with some other guy for some konigs, but decided against it. What do you guys think? Here is a pic of the rims <br><img src="http://i19.photobucket.com/albums/b184/ahs2003eagles/rims-1.jpg">

That's a pretty small profile but if you're running sportlines which is a pretty big drop, it should be ok. I run 235 series tires on my 17's but on a tein s tech drop and it looks good to me. Just be careful since it is so low profile that the rim can get bent or cracked much easier.

 

[Cs4g63]

I like them. But when it comes to rims and tires its up to you. Everyone has diferent taste. See if your friend will let you put them on and see how the car looks. If it looks like it is to small of a sidewall then get diferent tires to put on.

 

[bigbro6785]

Ya he already said i can put them on to see how they look. I personally prefer 18's, but I know i wont be able to afford them anytime soon. I figured i might as well pay 400 for 4 almost new rims and tires instead of 300+ for just tires. I like the rims, i think they will go good with the color of my car (barcelona red), i just hope the low profile tires doesnt throw it off to bad. Anyone have pics of 205/40/17's on theit car?

 

[generalu]

I bent/cracked one of my rims (215/40/17) after running over a pothole at a low speed. They were ADR's, and I'm sure the quality/strength of the rims came into play. I would suggest getting the tires a little bigger: 215/45 (which I believe are the stock size for GSX OEM rims).

 

[VTRICCO]

either go with a 45 of 50 profile. 40 is way too low

 

[Cs4g63]

Screw it. Burn the hell out of the tires until you can afford diferent ones. Just dont mess up the rims.

 

[DGajre777]

That's 82mm of tire. (40% of 205mm). Your stock tire (if you have 17s) are 215/50 comes to 107.5mm. Thats 25.5mm difference, which is about 2.55 cm, which is about an inch of rubber missing between a stock 17" tire and the ones you are looking at. It would look weird, and the wheel well gap will be huge.

 

[bigbro6785]

Im rolling on stocks right now, 16's (205/55/16). And the wheel gap wont be bad like I said because im on sportlines. I would prefer 18's, but 400 bucks is a hell of a deal. Plus i can always sell them when do have the money for 18's.

 

[Raph]

ive seen 215/40/17s and those barely looked right. i mean 205/40s will look funny .

 

[bigbro6785]

215/40/17 is just a wider tire that 205/40/17. It wont have anything to do with the sidewall.

Of course it would.. theres a difference in height.. the "40" means 40% from 205mm(width) ..or 215 mm-that would indeed make a difference in tire height and the way it looks

Example a 235 /40 /17 is way "higher" than a 205/40/17.

The 40 is the Hieght/width Ratio (Aspect ratio)

Ah. well you learn something new everyday. haha

^^^ What he said.

Which is why I said that it will look funny because you'll lose an inch of rubber compared to your stock tires. But with your stock 205/55/16s at 55% of 205, you are at .55 x 205 = 112.75mm compared to 82mm (that I mentioned in post number 8). Which is a 30mm difference, which is 3cm, which is 1.2". (Still with me? ) So your new tires will have 1.2" of less rubber. Now go to your car, mark 1.2" of less rubber on your tire and imagine how your car will look.

 

[bigbro6785]

But that is 1.2 inches off the diameter right? I did some tire calculator thing and it said i would loose about .7 inches in the radius, which means the wheel gap will be about .7 inches bigger, and the car will be .7 inches lower. Correct me if im wrong.

It says there is a difference in diameter of 5%, and they say anything greater that 3% can cause brake failure. Why is this? Also, will a smaller diameter/circumference cause any change in performance?

 

[92awddsm]

Just to help with an overall comparison, the 205-55-16 has an overall diameter of 24.877" and the 205-40-17 has an overall diameter of 23.458". As stated in a round about way, the 17" package is a little over 1.4" shorter than what stock size is. Even with sportline springs, it will look unattractive at the very least. Ride will suffer severly and you will eventually damage your front bumper entering and exiting some parking lots, driveways, etc. Considering the weight of the dsm, you will probably end up damaging both the wheels and tires if driven on roads that arent maintained on a regular basis(most roads in the US) The price isnt bad but I dont really think you understand how it will turn out. I am including a couple of pics of a 2g that has sportline springs and running 235-40-18's. Overall diameter on these is 25.401" which is almost 2 full inches taller than the 205-40-17"s you are thinkg about. This is a good stance IMHO but just imagine it with a tire 2" shorter. Get the idea yet?

And a little math for those that dont already know. We will use the 205-40-17 as an example. With 205mm being the width, 40 being the aspect ratio(which would be 40% of tire width) and 17 being the wheel diameter. You would multiply 205 x 40%(.40 for those that dont know how to use the percentage button on the calc) would give you 82mm which is the thickness of the side wall. Now, you multiply 82 x 2 to give you total sidewall of the whole tire(82mm between the rim and road, 82mm sidewall between wheel and fender opening) which comes to 164mm. Now, multiply 164 x .03937 to convert to inches. This is now 6.45668". Add the rim diameter to this, in this case it would be 6.45668" + 17. You will end up with a total of 23.45668" which would be overall diameter of the tire. Hopefully, this little bit of info will help others when trying to figure out what size tire to go with if they are looking for a certain height or trying to compare size to size.

A tire has a max load rating on the sidewall. A car requires a tire a minimum load rating. with that said, I think I'd be safe to say that no 205/40R17 has a load rating that is safe for our cars. It's a safety issue.

It is not a safety issue. The average load rating of a 205-40-17 is between 1100-1200lbs per tire. That would be 4400-4800lbs on 4 tires which exceeds our minimum required rating for tires.

 

[Merkles]

That is non-sense I am running 35 series on my 19s which is even less of a sidewall in upstate NY streets and I have yet to encounter any issues at all.

these are my 205/40/17 Falken's on my ADR Sokudo's. While they aren't too low profile, they are a bit narrow for the rim, and I would suggest moving up to a 225 or 235 mm tire. well anyway, here are the pix

I understand what everyone is saying. But everyone telling me that I need to go with a bigger wheel is not really an option I have right now. Its either buy the rims and the stick with tires that they come with, or buy new tires for my stock 16" chromes. Im planning one putting them on my car so I can see how the look first hand.

 

[91tsi2wd]

dude, put em on! i have em and they look great, or so everyone tells me. like I said the only complaint i have is the narrow tire, but they are the same width as stock, so meh.

imo, 17's are ideal, 18's are kinda too blingy for my taste, 17's are big enough to look good, yet still serve a purpose (not too heavy)

 

[RedTurboEclipse]

I have 17s, and run 215/40/17.. only because they were free. I will be going with 225/45/17s.

 

[DGajre777]

I agree with ^^ him. Just buy it for now, wait until you kill the tires and then buy 225/45/17s.

 

[bigbro6785]

I have another question. Like I said, I am on sportlines. Have front and rear camber kit, and already got alignment. But I still notice that the rear wheels butterfly in slightly (not at all in the front) Will these low profile tires be more suceptable to wear because of this?
