i have 15 inch rota slipstreams in 6.5 inch width. i am wondering what the maximum tire width is on a CRX with these wheels.
i know that near-stock is 195/50/15 but right now i have 205/50/15 and they work fine.
i see that a 225/50/15 will fit on the rim (it is pushing it, but it should work) but i wonder if it will rub somehow or otherwise have a negative effect on the car's handling, etc.
this is for a street car with weekend warrior dreams.
any intelligent input or experience is appreciated.

edit: yes, i realize that when wheel/tire combinations are changed, it can affect the speedometer reading, but i am willing to deal with that if i can see improved traction and cornering, etc.

 

i just ordered some 225-50-15's. i let you know how they work out when they get here

 

i have 205-50-15's on my wheels

 

ok, EF8opey. i would appreciate if you can subscribe to this thread or hit me with a PM once the your EF is rolling on the 225's

 

205/50/15's buddy, that'll do you good, and still retain really good sensitivity.

 

anybody got 205/45/15's ?? i seen a civic hatch with 195/45/15's and it looked awesom

 

subscribed i want to know

 

Before I can help you out - what tire is being used? R-compound or street tire? I need to know more about the car; "a street car with weekend warrior dreams" isn't very descriptive.

Any 225 won't necessarily be better than any 205. Most of the National-level STS ED9s are running 205/50-15s for good reasons. Also, a 225/45-15 is a lot better than a 225/50-15 for gearing purposes.

 

i had some kumho's v700 225/45/15 on my stock ls mesh 15x6 wheels barely fit but had no rubbing issues barely cleared. what is the offset of the wheel, that is what will be the biggest factor

195/45 R15 on 6,5jx15

It'll pinch the tire a little bit, but no big deal.

Sorry to ruin your fun, but 205/45/15s aren't made. They just dont come in that size.

As a matter of fact, I can take a picture of a tire i have at home that is in that size. Its a Dunlop SP Sport 9000. A set of 2 came off a car I bought from a dude in Germany. Ive been trying to find another set and cant, but that size does exist.

 

Here is a thread to support my claim also:

http://www.motor-talk.de/t285758/f81/s/thread.html

Its in German, but you can still see the tire size he is discussing.

 

205's look perfect IMO..rota group N's wrapped in falken azenis look real nice on 205's

 

Fine, it exists, but really rare. That german guy might have made a typo maybe?

Or I guess I could be imagining the set of tires in my garage have the same size on them... And no they arent rare, in Europe.

AFAIK, 225/45-15 is only sold in R-compound models; I have never seen a street tire in that size. Hoosier A3S05/R3S04, Avon Tech-R/Tech-RA, Kumho Ecsta V700, and Toyo RA-1 are all available in that size.

205/45-15 isn't sold at all in North America.

 

My .02

I would think the sensitivity you would loose from the extra sidewall would not be worth the extra grip you might get from a wider patch. Spending a little more $ on a good set of 195 or 205/50/15's would out perform the 225's anyway. The EF just doesn't need that much rubber.

You're on the right track. It really depends on what you're looking to do and what your tire limitations are.

For example, a CSP autocross EF needs a 225/45-13 soft R-compound tire on an 8" or 9" wide wheel. Choosing anything else means losing.

An STS autocross EF needs a 205/50-15 max-performance summer street tire, like Falken's RT-615, Kumho's Ecsta MX, BFG's gForce T/A KD, or Hankook's RS2-Z212.

An H1, H4, or H5 road race EF will need the 225/45-15 and/or 205/50-15 in a harder R-compound.

For a drag EF (which I must admit, I don't know much about), if you aren't running slicks, you ought to be running BFG gForce drag radials. Size will depend on power levels (i.e., a high power turbo car with a lot of traction issues may want something with a larger overall diameter to lengthen the gearing).

For a regular street EF, 195/50-15 and 205/50-15 are perfect. The tire selection in those sizes is enormous, and prices are cheap.

For snow tires without studs, 185/60-14 or 175/70-13 Michelin X-Ice, Dunlop Graspic DS-2, or Bridgestone Blizzak WS-50 work well. Studdable tires are even better.

This should be in an faq somewhere Good info

 

I had a crx with 215/40 on the factory si wheels(14)- it hanled like a champ. But it looked like an awd drag car

 

Excellent info in this thread. I thought it might have been better posted in the RoadRacing forum, but since this topic is EF-specific, I posted here. With the good discussion that has ensued, I am glad that I did.
Thanks to all, especially Targa250R for the posts.
Now I am thinking about tire brands and models to go with on my "street car with weekend warrior dreams." To elaborate on that, the car is (as most EF's probably are) a Work-In-Progress. It has never seen a track, but I want to Auto-X it and drag it, at the minimum. I know that slicks or the BFG's/Azenis are the way to go for drag, so I really want to know more about Auto-Cross and Road Racing tire/wheel combos.
I would like to throw down on the Toyo RA-1's but that would be stupid/wasteful on the street. I am partial to Toyo's because of excellent performance from a set in the past, but I do realize that other companies make some very nice tires, too. So, the 205/50/15 Toyo Proxes T1R look like the ones I will go with, but Falkens, BFG's, Kumhos and even Hankooks can probably compete with the Toyos. Of course, price and availability will have a hand in what tires I eventually purchase.
What do you think?

What class do you intend to compete in for autocross, and how many dedicated sets of tires and wheels are you willing to buy? Ideally, you'd want a different set of tires for street, drag strip, autocross course, and road course. Obviously most people don't have the means to have 4 or 5 different sets of tires for a single car.
