Looking to get a set of winter tires. Saw some Dunlop m3's at a decent price 195/55/16. Couldnt find a definate answer if these would fit on oem rims? Anyone have experience with the size of tire and does anyone know if they would fit?
It's going to work, but why would you want to put a tire like that on a heavy car like a Prelude? Another thing to consider is that the tire will fix but there may be clearance issues with the wheel and the brake caliper.

Many prelude owners in the north east use their OEM rims for winter and buy aftermarket summer tires. You need winter tires sometimes for safety reasons.
Yes the tire will fit but the only issue might be rubbing if he is lowered or maybe it hits parts of the wheel well. It's an OEM rim, how could it possibly hit the brake caliper if he is only changing tires? I think you are assuming he is putting on a smaller rim or something.

As for wanting this size, you're right. Winter up north can be crazy at times even in the city. I've heard also that a smaller contact area (195) allows for better traction. Anyway, i will give it a go and let you all know how it turns out. Not too soon hopefully...

the previous owner of my prelude had 205/55/16's; they worked but they looked goofy.
a taller thinner tire makes an appropriate winter tire?
acceleration, breaking, and traction would be reduced with a 195 width tire. I would try to find stock size wheels(205/50/16).
^I don't think you would be doing some crazy stuff with winter tires. I would suggest stock size as well but I guess if it fits...
I wasnt implying crazy maneuvers in the snow, just that if your gonna go with car parts its never a bad idea to go stock/oem or better. Since your tires are the the only thing that actually touch the road, you wouldnt want to compromise tire performance in any form.
but yes they could fit kinda of small; just be aware.
I'm a spoiled southern Californian so I have no idea about these "winter" tires you speak of lol.
But the common idea is that narrower winter tires have less tendency to hydroplane on the snow because the unit loading is higher than a wider tire. The other side to that argument is that you will have less overall traction due to less surface area. It all comes down to whether you are driving through packs of snow or ice. Having a narrower tire would be better for snow but having the wider tire would be better for ice. That's in theory of course, last time I drove on ice it was with summer tires...I know why they say "not intended to be driven through ice/snow or in freezing temperatures."
ok well hopefully i can help here...... a 195/55/16 is roughly the same outside diameter as the stock size 205/50/16...
i am not assuming that anyone doesnt know this already but i am just going to post for general info
stock size ... 205/50/16
205 is section width in mm
50 is aspect ratio
16 obviously rim size
soooo 205 x .50 = 102.5( tire sidewall height in mm)
multiply this by 2 = 205 ( i know this is stupid for our size but it will work for all sizes)
divide this number by 25.4 ( roughly 25.4 mm per inch)
this equals = 8.07
add rim diameter (16) == 24.07
same calculations on a 195/55/16 you get ---> 24.44
this is close enough that it will work fine, you will read slightly faster that spedo.... however since the comtact patch will decrease in size, there will be more pressure and therefore more traction in snowy conditions....in this case the decreased footprint helps but be careful of all other conditions as this size will have less lateral grip than the stock size.....it is negligible in the winter, but come summer i would atleast go back to stock
hope this helps....
( i could go on and on sorry, i used to sell tires for a wholesale tire company)
Hey thanks for the thorough analysis, I'm more confident than ever about getting these tires, especially coming fomr someone thats knows what they're talking about. Suprisingly, I can't wait for winter to come around to try these m3's out. Happy luding...

a 195 and 205 size tire are .78 inches differerant. with that said, performance companies like JUN race a prelude on 225 and 215 tires. that little differance can makes a big differance from stock(205) if you know anything about tires. what exactly do you mean more pressure?
if you take the same 2 tires, one with a 55 height ratio and one with 45, the 45 will hanlde better because of the sidewall is more rigid. the same concept can be applied on winter and summer tires.
also the demensions of a tire dont make it a winter tire, the construction and material do. soft wheels with several deep grooves are better wheels on winter roads as charecterized by the following link APA.ca
if your driving in moderate to light winter roads, so long you have all season tires, youll be fine. but i think at 195, your wheels will stick out further than your wheels and have a greater chance at damaging your wheels.
By more pressure, i mean simple physics, the same mass or load will be applied over a smaller area with the 195 section width. this is why it is said if you or on a frozen lake in the middle of winter, you should lay on the ice and spread out, therefore decreasing the pressure on any one point
this is why a huge tire like a 275 or larger section width is more apt to hydroplane on the same car as a 205.....( obviously i know this is impossible and the tire would have to be the exact same, with the same siping etc......just think of it as a physics problem, ALL things being Equal.....then this would apply)
as for being a winter tire, i dont care about tread compund, just talking about sizing, tread compund is a whole new topic. i agree that this size does not make it a winter tire!( but just so ya know a dunlop m3 is a dunlop winter sport m3 which makes this specific tire a winter tire.)
you are absolutely correct that decreasing aspect ratio will increase steering response. A lower aspect ration will allow for decreased sidewall flex...in sense you turn the steering wheel which turns the wheel direction which then transfer motion to the sidewall of the tire and eventually the tread that is in contact with the road, or contact patch. decreasing the aspect ratio will allow for the wheel to more quickly transfer motion to the contact patch of the tire.
hope this helps

i was just trying o explain some basics.......
also i just want to clarify a couple things, and i am not trying to correct you, just help ya out so please dont take offense as none is meant
195 section width has only to do with how wide the tire is, it will have nothing to do with offset of the wheels being positive or negative and sticking out..... maybe you could clarify your previous statement, i am unclear of its meaning
the reason racing teams use wider ties in racing is that they have increased contact patches which will allow for greater corner entry speed and the such, which is great for racing or summer or dry roads.....changing to wider tires is one of the easiest performance mods you can do..... in the winter however it is better to stay stock or could go narrower, obviously not too narrow but you get the drift....
please, any more questions ya have i hope i can help
In all honesty the profile, within reason, doesn't mean the tire will handle better. There are two reasons for this, even two tires with the same aspect ratio they could be significantly different in sidewall height. When selecting tires going to very low profile will reduce contact patch and possible allow the imperfections in the camber curve to prevent the tire from having proper contact with the ground. Having too high of a sidewall can also be detrimental to handling as the slip angle is so large the vehicle would have very sloppy feel. But not that this is true with tires for street cars only, F1 for example uses a 13 inch wheels with a tire that has about 6 inches of sidewall. The sidewall in these tires is obviously incredibly stiff as F1 cars use the tire itself as a form of suspension.
Tire width is also a big concern. Too wide of a tire will slow the vehicle down and add unnecessary unsprung weight. Obviously too narrow of a tire isn't good either as it offers to small of a contact patch but there is a happy medium. I was just at Honda the other day looking at the Realtime Racing TSX's and they were running Enkei RPF1's in a 17x8 with Hoosier R8 tires in a 235/40R17. They were also using Penkse shock's, which I was drooling over, but those are beside the point. The point is there is no reason to run wider tires than you need and also no reason to run too low of a profile.
