That all depends on what guy you have mounting your tires. Basically the limiting factor here is what kind of feel you are trying to acchieve and how low the car is weather the tire will clear the fender.

Let me explain. A. I have seen 275 wide hoosiers mounted on a 6.5" wide 15" rim for autox but here comes the feel part i was talking about. This is for autox u say so anyone reading this that is thinking for the street can ignore this. The wider the tire you go on the same rim you will get net more grip (think a big sweeper in autox) But you lose that "crisp" turn in. In other words you turn steering wheel and and there is a delay before the car turns so this hinders you in say a slalom. So like i said if your willing to sacrifice the "crisp" turn in then you can squeeze a fairly wide tire on a 7" wide rim. other factors would be what offset the rims are that will determin how much you can stuff in there without hitting the fender.

What car are u puttin this on? What brand tire are you considering and for what class are you building? FWIW a 245/45-16 has about a 9.5" tread width and is about 24.7" tall. what size is your oem tire?

Well street mod does have tire restrictions actually you need to run a DOT legal tire aka Anything up and including a hoosier A6 which is basically a slick with 2 grooves in the tread. The 245 /45-16 is bout .3" shorter than the oem tire so that is good.

Good luck that car should be fun.

245/45/16 requires a 16x7.5" or wider rim. I wouldn't run it on a 16x7" rim. The answer to your question is 225/50/16.

Not true... Reccomended rim for a 245 is a 7.5 yes but you can fit it on a 7" pretty easily. Like i said above i know of people who run a 275 on a 6.5" rim. Seeing as he is using this for AutoX i there is no problem puttin that tire on that rim. (other than the losing the crisp turn in i was talking about)

245/45/16 recommended rim is 16x8.0". Fits 16x7.5" - 16x9" rim. 16x7" is TOO SMALL. I don't know where you're getting your info dspsolo2 but it's bull****.

235's on a 7" wide rim is also stupid. 235/45/16 requires 7.5" 235/40/17 requires 8.0". You could pust a 235/50/16 tire on a 16x7" (or 16x6.5" for that matter) but it's too tall (25.25") and a WRX really needs something <25".

You can easily mount up a tire that's too wide for your rim. However, the sidewall will be like / and it will take huge stress on a turn. This will reduce the tire's effectiveness greatly. Tire width does not necessarily equate to better performance no matter what. Sacrificing correct fitment can hurt you more than the added width helps. 275/45/16 on a 16x6.5" rim is a lot of stretch; 67% wider tire than rim. That tire is spec'd for no more than 30% wider. Do you really think that width is worth that kind of stretch?

The answer to this thread is 225/50/16

The answer to this thread is 225/50/16

Where i get my info is that i have been racing in AutoX for 4 years now and i have researched and talked to national autox drivers (best autox drivers there are) about this and much much much more.

I have alredy stated what you gain and what you give up on squezeing a bigger tire on a rim. Gain- grip Lose- steering response.

Quote you "275/45/16 on a 16x6.5" rim is a lot of stretch; 67% wider tire than rim. That tire is spec'd for no more than 30% wider. Do you really think that width is worth that kind of stretch?" YES!! the top NATIONAL driver in D stock (integra Type R) Runs this set up and WON NATIONALS.

So yes it is worth it to squeeze it on there and yes i know what the hell im talking about. How long have you AutoXed? By your response of not knowing what you are talking about i would say NONE. Am i right? So keep your mouth shut on what you do not know and stop spreading false information.

Edit: Not to mention the question is HOW WIDE of a tire can he fit not what the reccomended tire so apparently you cant read ether.

Mosc...

I am disappoint.

I don't race (although I'd like to) so I will rightfully take my position below dspsolo2(as you should have) and take his word for it. However, I do hang around the Renner Motorsports shop enough to know that "recommended" and "possible" are two completely different things in the world of motorsports.

Obviously you are reading a tire recommendation...this does not help at all in this case as he is not using the tire on the street. If that was the case you would be correct. I use a 225/50/16 on 16x7s on my street wrx. I will soon be going up to 245/40/17 on most likely an 8 inch wide wheel. This will put the tire just past the edge of the wheel. Perfect for the street, but if I were to track the car I would probably go with 255s on a 7.5inch wide wheel-not quite as extreme as 275s on a 6.5in. More ultimate grip and light (less rotating mass from the narrower wheel).

I suggest that you listen and research before speaking on a level way over your head.

1) he doesn't need slicks, it's a ****ing 30 second long auto-x course.
2) he never said they were track only tires.

What works on the clean surfaces of a track does not equate to the street. Driving around on race rubber with that kind of stretch is not safe for the every day bumps we call PUBLIC ROADS!

Can you not freaking read!!!!!!!!!? Are you that simple????

He says right there that he got a set of rims STRICTLY FOR AUTOX. so YES he said they are only for autox.

And yes to be competitive in autox you DO need "slicks" depending on the class. He runs in street mod which allows you to use Hoosier A6's which are basically DOT legal slicks with 2 grooves in them.

Seriously give it the hell up you dont know what your talking about and you clearly can not read. What is your problem?


Edit: FWIW i am sorry i am being rude here but when i come across someone who clearly does not know what they are talking about and is spreading false information and clearly does not "get it" then some times being rude and blunt is the only thing they will understand. I'm not usually like that i am more on forums to research information and help others where i can.

I don't think those comments imply he won't be driving serious mileage to get to the track, do they? What if the track is 100 miles away? Would you recommend he drive on twice the recommended tire stretch for that kind of distance?

FWD Integra needs more grip in the front to be competitive than a suby does too. Also, Auto-X is often a sport for more casual enthusiasts who don't have an all out track car. 275/45/16 A6's cost over $1000 for a set. Also, you're assuming he's a good enough DRIVER to really make use of all that. 90% of auto-x drivers are not. For most of us, it's not all about winning on a national level, ya dig?

You just dont give up when your wrong do you? You are only digging yourself a deeper and deeper hole.

He said he has a seperate set of wheels and like 99.99999% of AutoX drivers who use sticky tires i can almost guarantee he will switch wheels when ge gets there. BUT THATS NOT WHAT IS IN QUESTION HERE

An integra needs more tire.... are you kidding me???????? A suby needs more tire all around... 2 basic reasons (not going into full detail here) 1. Subie weighs a lot more 2. A good bit more HP and TQ than a integra needs more tire as well, Especially to be competitive. but again THATS NOT THE QUESTION HERE

Yes AutoX is a more casual form of racing but THAT HAS NO BEARING HERE!!! he asked a simple damn question and i answered it! Cost????????? AGAIN He didnt say anything about cost THATS NOT THE QUESTION HERE ETHER!

Who the hell are you questioning his skills? No matter if your brand new or experienced more tire will be better. (within reason and to a certin point). once more THATS NOT THE QUESTION HERE!!!!!!


Seriously guy i dont know you, but as has been stated by me and others you are WRONG here. Lick your wounds and go home. I am trying to put it nicely but you keep posting CRAP that you dont know about. I am only trying to help him here. This has gone on for too long the question has been answered (correctly by me not you) and this needs not go any further, But if you continue to post false information and crap here i will continue to tell you why you are wrong. Your choice, look dumb and stop posting, or continue to post and look even dumber.
