Tyre/mag size, DC2r

[tinkerbell]

so what would you list the advantage of bigger rims/tires to be tink?

apart from being able to run bigger brakes.........

depends on many factors - most important being weight of the car...

[tinkerbell]

for example, whiteline.com.au states:

Tyre width, wider is better right?
Not always, it is a general misconception that wider is better. The object is to have as much tyre contact with the road as possible, but there is an optimum limit to this. On cars with anything other then a live axle suspension, such as McPherson at the front and multi-link at the rear on the S15, a wheel will have already have some negative static camber in it's standard form. This means that the weight of the vehicle is already not evenly spread over the width of the tyre, and is only further shifted towards one edge (usually inside) of the tyre as the suspension moves through its arc due to built-in camber curves. Wider tyre have other detrimental effects such as increased aquaplaning and friction (resistance) as well as increased steering feedback which may be good but up to a point.

It is also quite easy to "over tyre" a car depending on the wheels used. A tyres' width is designed by the manufacturer to work in with the wheel size, suspension geometry and vehicles weight. Increasing the width of the tyre will not necessarily increase the contact patch as the weight of the car is the same. The shape of the contact patch will however change under these circumstances, hopefully to the benefit of lateral (cornering) grip but only if they are fitted to the correct rim size.

as i said - it depends - no "one rule" about it...

interesting, i have seen and heard of people using 245/225 combination to great effects, I guess no easy way of telling unless you test it out with your setup

[00dc2]

it says that the manufacturer designs the whole setup to work well as a whole..

so why would you want to go smaller than what Honda originally designed the thing to run on (16x7)(215/45/16)??

i know why (less weight, cheaper rim & tyres) but surely purely interms of performance 16x7 215/45/16 would be better?

i have never driven my car on any wheels/tyres other than 15x6 (205/50/15) so i cant really say too much.. surely there are experienced people here who have experienced many sizes?

maybe you have tinks?

[Jingers]

on a whole i think cars modified should not be looked at in the manufactures original intentions.

Alot of intentions go right out of the door as soon as you install aftermarket sus. Original manufacture must have looked at the geometery of the sus and obtained the optimum between comfort/economy/performance. I know its an itr but still tyres wearing out every 5k isnt an option.

So if you look at it this way if its possible to get better performance and you dont care about tyres wearing out then the manufactures intentions are not the best intentions for you.

Why 205/50 15" ?

IMO this is too wide for the stock 6" wide rim. 195/55 would feel much better.

car came with that size from the previous owner.

i saw one of the dc2r teams in the production racing series (cant remember the exact name of the series now) back a few years ago.. like the pink donut king sponsored i think.. anyway.. i seem to recall that they were running 205/50/15 on that.

i figure that wider = more grip

maybe my next set will need to be 195/55/15 just to see what its like.

have you run with 195 and 205 on the stock rim freakygeek? tell me about your observations if you have.. anyone else?

[VTECMACHINE]

Quick question since we are talking about DC2R tires etc.

My tires atm are 195/55/15 on stockies. What size tires would I be needing on a set of 16x7. 205/?/16 ???

[Dny]

I'm using 195/55's on my stock DC2R rims, what ad/disadvantages would there be moving to a 205/50?

[freakygeek]

Yes, but not with the same brand of tyre so the comparison is somewhat void.

However if you look at the way a 205 mounts to the 6" rim it is very "baggy", ie, the tyre looks too wide for the rim. 205/50 would work much better on a 6.5" or 7" rim IMO.

195 is the ideal size for the OEM 15" wheels.

I believe JCE experienced this same phenomenon with his CRX, going from 195 on the OEM wheels back to the standard 185, and making the cars response feel much sharper.

i run 16x6 rims on the street with 205/45R16 tyres...

wider "contact patch" latitudinally (east/west)

but also means the "contact patch" is narrower longitudinally (north/south)

I run 205/45/16 on my 16x7. I got 205/50/16 on my spare 16x6. I prefer the 205/45/16 though.

[tinkerbell]

i DID run 205/50R16's but they were semi-slicks and rubbed the rear guards with +40 offset rims...

i really cant imagine why this would be the case?

i will definately go 195/55 for the next set for the stockies though..
