Are you looking for an all race tire ? Or a tire than you can race on and still be street legal?

Look into the Kumho VictoRacer. They provide lots of grip, but are a race only tire. And also, beware that with a tire like that, you might want to consider gettin your oil pan baffled so the higher G forces in the turns will not starve the engine for oil.

For street legal and race ability, the Azenis Sport is a popular choice. It is by no means light though.

 

honda-tech wont aloud me to participate on the classifieds forum so i use my name to place what i need and my cell number dallas forthwork area north texas , when i will be able to get a avar ??? any one can tell me

 

Haha that's funny what you did. Anyway, wider will give you more traction going both foward and in cornering, but size isn't what matters most. It's all about compound, sidewall construction, tread pattern, tec...

 

the 205's offers more tire contact area than the 195s but there are other factors to consider. sidewalls, tread pattern, rubber composition, weight of the rims, offset of the rims... etc...

 

195-50's are tiny for integras, you should take that off your list and possibly consider 195-55-15's vs 205-50-15's

Actually tire contact area remains the same, assuming same vehicle weight and tire pressure, no matter what tire size you use, be it 195/50, 195/55, 205/50, 205/45-16, 215/40-16, 205/40-17, whatever. The shape of that contact area may change (if it gets wider, it also gets shorter in the other dimension), but the total area of rubber contacting the ground remains the same regardless of tire size.

 

PatrickGSR....

How does this work then.....the contact area and the contact patch are the same, so, the wider the tire, the wider the contact area? Would that not be correct?

I know most cars have a contact patch roughly the size of a human hand, so, why wouldn't a 235/40-15 have a wider contact patch than a 195-55-15 ?

I do understand that when measuring the coefficient of friction, you only take into account the amount of tire that is actually touching the ground.


So what am I missing?

 

the size of the contact patch is determined by weight/pressure.

Yes a 235/40-15 would have a wider contact patch than a 195-55-15, but it will be shorter front to back. Overall it would be the same size. What you get there is better turn in response and less resistance to hydroplaning.

This also applies on paper, and I have seen some measurements that actually do indicate a wider tire will have a contact patch that is *slightly* larger. That difference could be attributed to many factors that cannot be normalized (tire construction for instance), differences in diameter, etc.

In general though, wider does not equal larger.

 

This may help you,

I recently purchased 4 brand new Falken Tires 512. But I purchased 2--205-50-15 and also 195-50-15. I then put the 205's on the front and the 195's on the rear. Now the width patch is a considerable difference, about 1 inch, and the height difference is about .8 of an inch. The handaling is alot nicer, the steering is more precise and the car now rotates easier as of the less contact area in the rear.

I also tried it the oppposite with the 195 in the front and 205 in the rear and the handling was strange. it was like the rear was pushing me, alot of understeer rather than the preffered oversteer.

Well I hope this helps, it helped me alot and I definetley glad I made the choice.
BTW There is a thread in the Road and Autox forum about this setup

 

interesting test!

Couldnt you just deflate the tires some? LOL
