225/40/18 on stock USP 18x8 wheels. Pics Plz

[Charlescrs6]

I know stock is 235 and I don't really want to stretch, but I did find a good deal on some 225s. What do you think?

[Gooner1886]

Do it youll like it better than 235 and its like no stretch

[Charlescrs6]

Do it youll like it better than 235 and its like no stretch

I feel like wheels with more concavity than USP wheels look better with a slight stretch. I'll probably get these since I got such a good deal on brand new tires.

[shoppingcart111]

Not the best pic or close up, but these are 225/40R18 on USP wheels from when I bought the car.

[Charlescrs6]

^Did you think it looked good or would you have wanted 235s?

[heateris]

You'll get a better contact patch with 235/40. Larger contact patch = better handling.

Exactly, but AZers are known for form over function...

[Charlescrs6]

I'm all about function, but if I can save $400 by going with 225s over 235s, I might as well.

[kwik_shift]

I'm all about function, but if I can save $400 by going with 225s over 235s, I might as well.

so basically saving $$$ > Function. If function was # 1 then money would be no issue.

[4Rings3Liters]

Your not entering your car at Le Mans anytime soon so a 225 tire over a 235 tire isn't going to make a difference. If your saving money absolutely go with the 225, it's not a huge difference.

If money wasn't an issue and it was all function I wouldn't be in a B6.

I love the retarded exaggerations, someone always has to make one... You obviously don't get it, one shortcut here, one shortcut there, it all adds up, then you have to make an emergency maneuver because of some dumbass not paying attention behind the wheel, and god knows they're everywhere. You can't predict this shit, no matter how safely you think you're driving, you're sharing the roads with all kinds of morons, especially on this continent... Totaled cars, lives lost, who cares, dude saved 400$

[cabreezy]

not sure what the big deal is, stock wheels on my A4 were 215 in width, so technically the tires he's looking at using would be safer than stock according to your logic right?

Assuming the stock setup was any good... I had the 15" wheels with 215 series tires as well, and I'd classify that decision by Audi as a crime against humanity.

It's a daily reality chump... Actually, it's an hourly reality in the US alone.

[4Rings3Liters]

It's a daily reality chump... Actually, it's an hourly reality in the US alone.

And it's all because people change their tire size. lmfao Everyone on here has to upgrade to 8.5" or wider wheels so we can save lives.

If your comprehension wasn't worth shit, you'd notice/remember where I said "it all adds up" because this logic you apply to tire choice is the same logic you apply to everything else. And a moron behind the wheel is born.

Btw, those 15" wheels are a HELL of a lot ligther than the 18" USP wheels, not far from half the weight.

Ok sir, your right. Just out of curiosity do you know what causes most accidents? Hint: It's not anything to do with equipment on the car.

Do you think the driver of the Cayenne that dodges the truck in the clip gives a damn? No, he's happy he's driving a Porsche and not some piece of shit American SUV with Firestone tires... He escaped possible death because of equipment. And the most important piece of equipment are the tires since those four tiny patches are the only thing that connects the car to the road. Trying to save money on tires, be it going with some shitty brand or downsizing, is just idiotic.

HAHA ok, in that case one word doesn't complete a sentence. So you're still an idiot.

[mxrz]

It's an imperative sentence, it can be as short as one word. The missing word from that sentence is implied; the subject, being anyone else that wants to have a go. So yeah, nice try. NEXT!

Btw, happy 4th of July.

[Elliott]

You guys are just so cute.

BTW, I've been running 225/40 tires on my 18" wheels for 3 years with no adverse effects.

[heateris]

I'm all about function, but if I can save $400 by going with 225s over 235s, I might as well.

If you want the larger size, you'll always find a deal.

[shoppingcart111]

^Did you think it looked good or would you have wanted 235s?

Personal preference, I would stick with the 225, I have 235 on it now and the 225 is more stretch the 235 is a straight profile. Now that it sits lower i want to go back to 225.

[Asharp27]

4R3L ... In Canada they believe in the advertising tire companies produce a bit more than we do, but they esp hate the AMERICAN ones. hahahaha,

i'm all about logic bro but yours is twisted in so many ways. On some very basic level your right, but every decision isn't black and white, just because he doesn't find it imperative to spend an extra 400 dollars on tires so they can be (how ever many inches?) wider, which like previously stated is bigger than stock (which i am well aware means nothing to you) but is clearly safer than 80% of the cars/ drivers on the road doesn't produce an idiot driver and mean that he is going to proceed to get all of the engine work done at wall mart. (and proceed pimp his car out with buick port holes, hahahaha.) yes all of the little things do add up, you are correct and the problem is not being aware of that but if you think that just because someone is weighing the value of 400 in wider tires over the value it would give them driving makes them an idiot, your mistaken.

to the OP 225's ride just fine, had both 225 and 235s at some point. just depends on the look your going after.

[gaith]

i had 225/40/18 and then switched to 235/40/18... once they are worn out, i am going back to 225

NOT worth it, imho:
1. no 'performance' difference (maybe at extreme speeds)
2. more expensive
3. looks nearly the same (to most untrained eyes)
4. steering wheel is heavier

[Charlescrs6]

For anyone that cares, I'm happy with them.

I dont see your logic? Most cars stock wheels are around 195-205's with a high profile sidewall. Therefore you are saying most all manufacturers produce unsafe handling capabilities. If hes not tracking the car or trying to get every last bit of performance a 225 is not going to make a noticable difference. My stock wheels are like 15x7's and I ran 195's. I'm now running 215's and they handle much better. Less sidewall roll and they stick to the road just fine. Your an idiot, hangup the keyboard.

[mattro]

i'm running 225 on 18 x 8.5 wheels... I must be stoooopid !!
and no, I wouldn't even put 235 on an 8.5 wheel either, I love my 225 too much.
the handling of the car can't even compare to when it was stock height with the high sidewalls, narrow 16'' tires and yet according to mxrz I still fall in the idiot category. actually according to him we're all idiots, cause when putting money on wheels/tires we should all go widebody with at least 285 tires, otherwise we're just cheaping out and compromising the potential performance of our cars

[mxrz]

Is this an admission of ignorance or are you asking a question?

Those 15" wheels that Audi put on the A4 weigh in at exactly 15lbs. The stock USP wheels tip the scale past 25lbs. Do you understand the difference? There is a reason Audi puts 235 series tire on this 8" wide wheel, and now we're talking 8.5 inches, which is even wider and heavier. So if I'm an idiot, Audi is too. And actually, yes, those narrow, tall tires are unsafe during emergency maneuvers, but what would you know about that, you passed your driver's license test in the good ole USA, (even Canada) where there is absolutely no requirement to demonstrate any kind of actual skill behind the wheel. Just FYI, by local standards, in Sweden, American drivers are considered "unsafe", wonder why?

Your an idiot, hangup the keyboard.

I see a pattern here. Tell me, do they teach you fools in school the difference between "your" and "you're"? I'm beginning to think they don't. It helps not to make yourself look like a moron with no education when you're trying to insult someone because they have a different opinion. Hangup my keyboard? Listen here noob, who joined a couple of months ago, I am an asshole, yet, I've helped more people on these forums than you ever will, so please, know your role, and kindly fuck off, till you've actually done your part for the community.

I can think of few valid reasons why you are a self proclaimed idiot, however, none of what you said is "according" to me. This is all your own words based on your abysmal understanding of my argument.

[PurpleNerple]

You right, wider tires are better because they weight more, provide tons more traction, and save lives!!!

Your saying the 15" wheel weighs less and has a lighter tire, and you say the 18" wheels weigh more and has a much heavier tire so the extra traction is needed in order to compensate? So in theory, using a skinnier tire would weigh less and help accomodate for reduced width/traction, making the safety hazard extremely insignificant?

I always love when people are the grammar police, you understood what I was saying and thats all that matters, this isn't a spelling bee. I joined about 2 years ago but changed my name a few months ago because I forgot the password and the password to my email in order to retrieve it haha. Just because you give advise doesnt mean its correct. Until you ride a set of 225 or even 215 tires on a 18x8 wheel dont go about acting like you have professional expertise on the subject. The traction loss is so insignificant that this shouldnt even be a question of safety. Unless this person plans to travel at excessive speeds in heavy traffic or lacks quattro i'm going to have to dissagree with your statements. That may apply to the safety of racecar drivers but in the real world most people dont go about tracking their audi on public roads.

I'd love to hear what you have to say about stretched tires haha.

My point was that if you're going to increase the weight of the wheel and increase the weight of tire as well, you should increase the width (contact patch) of the tire, and since we're talking about rotating unsprung weight, the upsizing is not proportional, it is exponential, so one step bigger doesn't equal one step larger, more like two steps larger. When Audi went to 18x8 from 15x7, they selected 235/45-18, for exactly that reason. Actually, even the smaller, 17x7.5 wheels come with 235 series tires.

That may apply to the safety of racecar drivers but in the real world most people dont go about tracking their audi on public roads.

I do have professional expertise on the subject actually, which is why I often get involved in discussions about tires, wheels, suspension, and the dynamics of how it all works together. I've been involved in everything from theory, concept, design, engineering, manufacturing and testing of custom built race cars, street legal kit cars and race prep projects involving everything from sports cars to full size trucks (common in Europe). Going from one size to the next in tire width does make a noticeable difference. Even changing the size on two of the four wheels makes a difference that can be measured on the street. Try reverse staggering tires on an A4 quattro (235 rear, 245 front, for example) and you'll notice how understeer is diminished by a good deal. Not completely, obviously, but noticeably, for sure.

I'd love to hear what you have to say about stretched tires haha.

Go check out tire specs on TireRack.com, alot of tires can be noticeably stretched and still be within spec. If it's beyond spec, I'd simply recommend against any kind of spirited driving. Stretching, from it's European origins is about running wider wheels with the same tire, not same wheel with skinnier tire. People that do the latter are just ignorant, but the former is an acceptable practice.

BTW its pretty damn easy to curb your rims with 225's, i won't be going with them next time. a buddy runs 245's on stock sport suspension without rubbing and it actually looks really damn good.

[mxrz]

245 series are a good match with 8.5" wide wheels, and they don't look like balloons like some people claim;

man its so funny how someone is in here asking a dam question and some people are in here tryin to be be freakin english teachers!!!!!
