Pic very rel. I like their look, but car just too stiff for roads that I'm riding lately and I don't want to change entire car to some suv. Will changing rims to smaller bring any noticable difference or is it just not worth it?
It most definitely will.Make sure you adjust your pressures to keep the same load capacity.there are calculators available online
The tire itself also has significant effects, the Eagle F1 Asymmetrics you have are sportier tires with pretty substantial sidewalls for more feel but also more noise and a harsher ride. A good commuter tire on 16" wheels will ride really softly in comparison, but shitty tires can also undo a surprising amount of that advantage and bring back a lot of annoying noise and unwanted ride characteristics.
>>28638152>same load capacitylol this is funny
>>28638142Yes, more meat on the tire = more comf.
OP here, thanks for relatively quick answer everyone.Should I rather aim for tire that is narrower/thicker or wider/thinner?
>>28638208find a tire that best matches the width of your current tire.
>>28638208Keep the width, minimize the diameter (but make sure your brakes still fit)
>>28638142Probably, but I've tried driving with an inch difference (10% depth difference), and barely noticed much.The width of the tyre might be a factor too, it at least affects the depth measurement
>>28638217The difference between 18 inch and 19 in is huge and the difference between 19 in and 20 is even bigger. Below 18 it is hardly noticeable unless you have really stiff suspension
>>28638142willtheyfit.comUse this to help figure out total rolling circumference, width, clearance, etc. Do not forget to pay attention to offset (ET) of whatever wheels you're looking at.If it were me, I'd just go down to 17s. I had a set of summer 19s and winter 18s on my last Audi and the difference was pretty massive when I'd swap between them.
larger sidewall will likely make the car feel softer.otherwise it will make no discernible difference whatsoever.outside of unsprung weight the diameter of the wheel and tire have zero effect on the suspension.....
>>28638264>I'd just go down to 17sI'd take most radical change and I've seen smallest rims that are used be manufacturer in my model are 16, which seems reasonable. I need my car to become as comfy as possible. Something as soft and family friendly as e.g. Passat, except that it's still my A3.
>>28638237>>2863821714 vs 16 is a pretty big difference. But by that point you are comparing 175/65/14 to 205/55/16, which is a enormous sidewall difference.>BMW i3As sexy as it is, its a subtle fuckup. Why not run the same dimension front and back, to decrease the tire cost? Or get a cooperative OEM to offer a worse version for their shitboxes?
>>28638971Yeah, that does seem reasonable. Can't go wrong by matching up to an OEM size option.
>>28638142Make sure your tires are properly inflated I can't stress that enough. I use the gauge on my compressor and it's innacurate. I bought a tire pressure gauge only to find out for years I have been over inflating my tires. The ride quality was really harsh I thought it was my suspensions fault. Be sure you do this when the tires are cold so the day after before you drive
>>28638287Ackshuwally the larger the rolling circumference the less it follows the contours of a bumpy road but its not a huge effectLess width doesn't effect ride quality much but will somewhat decrease noise and unsprung weightSmallest wheel that will fit over the brakes paired with the highest rolling circumferance tyre possible will give you max sidewall and lowest unsprung weight. German cars come with alot of wheel options so you can look in the brochure for the highest circumference wheel/tyre combo (which will probably be for a sport model). Unless that sport model has different fenders and rear quarters that circumference will fit your car with tiny wheels. You can even go slightly bigger circumference (put shit tyres on and test for clearance first) if you don't mind the speedo offset.tyre pattern should be non-RFT, non-sporty but also not efficiency focused either, as low a load/speed rating as you can get. Michelin primacy is usually the goat pattern but expensiveunderinflate your tyres a little - OE specs are always abit too high since they assume the car is fully loaded
What coilovers should I get if i want a comfortable ride? Eyeing up KW v2
>>28638142Yes. Stick to the OEM rims, confirm the smaller ones fit over the brakes. Ideally got those made for the lower trim of the same model.
>>28638142I have a fat car with 235/60/15 wheels and I can fly over speed bumps, especially these gay things, while NPCs in their niggermobiles with tiny sidewalls almost always have to crawl over them at 10 kph. Make of that what you will.
>>28638142You won't be able to tell a difference but you think you will. Everyone always says the same thing "no no no i CAN feel the difference" but they can't. They only think they can because they want to. In reality 90% of your ride quality comes from the suspension. I've done both and neither times was any difference ever felt. I moved from 19 to 17 and 18 to 20 and blindfolded, you wouldn't know any difference. It's all suspension. Try "flying" over a speed bump in a car with stiff suspension, doesn't matter if it's got 235/75/15 it's going to compress your spine and make you a little shorter.
>>28640098Are you saying that everyone else in this thread is wrong?
>>28640657He's right, but I'd put the percentage at 70% and would specify that the suspension has to be in good condition (no bushings on their way out, proper shocks and so on) and not poorly-designed.
>>28638208The most important thing for handling is actually to fit a given tyre on a wider rim. When tyre is pinched on narrow rim, will fold and buckle under lateral forces. When tyre is spread out on rim, will resist forces and stay posed, like great pyramid of giza.For a given size rim, a wider tyre will not necessarily improve things, but for a given size tyre, a wider rim will. Does that mean a narrower tyre on a given rim will offer improvement? In wet conditions, it definitely will. On the track, it depends; you're trading off more cornering stability with less longitudinal traction (acceleration and braking), which can either improve or worsen times depending on the kind of car and the kind of course it is.
>>28641055Lateral tire deflection is overblown, it's not a problem for normal driving. You have to really push it even with 70% sidewall and heavy vehicle to get it. OP is more likely to encounter abnormal tire wear if he decides to go outside of factory spec dimensions.
>>28640098It all depends on sidewall construction (and psi to a lesser extent). A tyre with a very stiff sidewall or a tyre that is highly inflated for rolling efficiency will stay stiff at almost any diameter.Take a soft touring tyre and make it a larger diameter and air it down and there will indeed be a huge difference.Of course the change in tyre itself also makes a huge difference, often the hugest different at that, besides or without any other change in fitment or inflation pressure.Most people will always inflate their tyres to the same spec as their car's stock tyre specification regardless of what they put on, and OEM's tend to set a high pressure spec for the stock tyre because that improves the mpg.
>>28641075I'm not telling you to go outside factory dimensions, I'm telling you that all tyres come with a range of rim dimensions, and ceteris paribus, the wider end of the range will be better.
>>28641083And I'm telling you he won't notice the difference inside factory dimensions for both rims and tires. What's a tyre, by the way? Are you gay or something?
>>28641086Speculation about someone's ability to notice things is not my point. I am simply relaying to you the facts of the matter in reality. Take it as you will.
>>28638971Again, make sure it fits the brakes. Sometimes a lower spec german car will have smaller brakes, so that car with 16s might not be the same as yours.
>>28641080>Most people will always inflate their tyres to the same spec as their car's stock tyre specification regardless of what they put on,Unless you change the weight of the vehicle, this is a good rule to follow.
>>2864065790% of living is feels based, something that the individual thinks is good it's all about feels. When you change your oil do you feel your car drives better? I do.
>>28638142i went from 19s down to 16s. it absolutely will make for a cushier ride if you maintain the same tyre diameter. In my case, 235/40R19s to 215/60R16s, maintaining almost the same diameter (slightly smaller so speedo will read marginally faster than what it did with the stock wheels, which is likely still higher than your actual speed already).Quicker to accelerate, better fuel economy, and potholes are a trivial matter now. I think with 205/65R16s it'd be even cushier.
>>28643702most modern cars pull power as the oil gets dirty.people think the change oil light is just a dummy light.
