Default Potenza S03s 205/50/15 vs 195/50/15


Ok, tirerack has the 195s for $76 each, and the 205s for $123 each.

That's $47 a tire ($188 total) more than the 195 width tires, for only 1cm extra width.

Now, seriously... how much difference is there in traction? These will be going on some rota slipstreams...

Oh, and I wanted the falken azenis... but those are impossible to find. After I ordered them from tires.com they emailed me saying they did not even know when they would get any of them... =P

So I'm looking for alternatives. If you have any suggestions (think cheap), go ahead

Discount told me the same thing, three days later they were on the car. You may want to call them.

Edit: this was just last week

You will have better rim protection (from curbs etc) with the 205/50s.

You will be under-tired with the 195/50s.

Always go wider if you can. 195s are too skinny imo.

Will you stop post-whoring in my forum...


I would stay with the 195/50/15 not only will you save yourself money, and your Final Drive will be higher comparred to the 205's, and they weigh less.

now these factors are very small, and the main reason the 205's wont handle $180 better than the 195's

Well, I'm seriously fighting traction as it is... on my 17" wheels w/ Paradas right now I can't get any traction in first and second gear from a roll.......

But I mean, you are right, $180 is so much money for 1cm.

Any other affordable tires? I need traction...ehh....

Hey dustin,

I think I saw some on groupbuycenter. $248. 205-50.
http://www.groupbuycenter.com/buy.asp?row_id=4566

My S03s are 1/2 gone after 6k. So it's about $50/1k miles. Ouch.

So when I going to see you at an autox (one in March16/17) or track day I saw you tooling around in a red? CRX a while back.

Dustin...that hilarious...hahaha...can't stop laughing about the truth.

Bigger tires...I would call one of the big guys to see if they have any in stock, it took 2 weeks for mine to show up, but I have the Azenis on my car again, and I have a very big smile on my face (sorry about the ClubSi graphic, but it is a better visual of my face while driving on these tires)

The paradas are actually pretty good tires compared to others I have owned. They stick OK but the 205/40/17 is killing me. 15" slipstreams should be better...

Go with the 195/50's and save some money.
Very true.

People who say you will damage the rims are full of it.
<Raises hand> I prefer 205's over 195's. Comparing the side wall on 205/50 and 195/50 is quite a big difference, even if the math tells you that it's a very small diff.

People who say you will not have enough tire are full of it. (what ******* size comes on the car anyway? 195/55 -- yeah).
Steve, do you run the same size tires on your BMW as the manufacturer suggested? What about your ECU chip? Is it stock?

If you want to be a ricer and buy into the bigger is always better myth, why not slap a set of 225/50's on their instead?
I'm a rice boy... and I would love some 225's... only if the stock rims came in 6.5" or 7" width.

Seems someone had the wick of their tampon lit! Time for a Midol.

The Type R is under-tired with 195/55. Take the Type R to the track and find out for yourself. (R compounds don't count)

You guys are nuts. There is such a small difference in contact patch between a 195.50.15 and a 205.50.15 on the same size rim, given the limited amount of negative camber that is even possible with even a reasonably lowered integra, that I bat given a A/B test you couldn't shave a 1 second time off of your favorite track... The size of the contact patch does NOT depend on the width of the tire. Increaseing the tire width 10% does NOT increase the contact patch, only changes the shape of the contact patch.

Why? The vertical force balance must be maintained, lest the car either fall thru the ground or bounce into the sky when you alter tire sizes. Huh?

Consider, for simplicity, a 3000 lb car with four 255mm wide tires (that's 10 inches in civilian speak) inflated to 30 psi. It presses down on the parking lot with 3000 lbs force, and the parking lot presses back with exactly 3000 lbs force. How big is the contact patch? 3000 lbs / 30 psi = 100 sq inches. If the car's perfectly balanced, that's 25 sq in per tire, or a contact patch 10 inches wide by 2.5 inches long on each tire.

Change the tires to 275mm and (if they weigh the same as the 255s) the car still can only press down with 3000 lbs, still resulting in 100 sq inches of contact patch, or a patch 10.83 inches wide by 2.31 inches long

OK, wider tires really do weigh more, so that's say 3012 lbs, which at 30 psi gives 100.4 sq inches of total contact patch. So that extra 20mm width and 4 lbs per tire increases your contact patch by 0.1 sq inch. from 25.0 to 25.1 each.

So why do we like wider tires on pavement? It ain't 0.1 sq inch. Its that 0.83 inch wider contact patch if you're working the tire at its limit, because that's more rubber resisting along the line of lateral forces in a turn. If you're not working the narrower tire to its lateral limit already, the added width doesn't mean much, well besides sex appeal anyway.


I am running 195.50.15, I will change to 205.50.15 because the 195.50 has just tooooo much gap and I am not going to lower my car anymore that I alread have. It has nothing to do with traction because there really isn't going to be any gain there.

How much extra wheel gap is there vs a 205/50? As a side note would not the extra width in the 205/50 be offset by side wall flex?

I want to change one word in dustin's post so I can make a joke. Hope you don't mind, dustin.

Hehe, I like your forum. The people in here actually change the tires on their cars rather than changing their interior light bulbs to purple.......
That's because we don't have map lights!!!
