I can get anything I want for free from my dealer. I am not going to upgrade the suspension or lower the car at all. Most likely gonna get the Falken Azenis

Should I get 215s like the stock? 225? 235?

What about the "middle" number. I'm gonna stick with 17's.

Will 235 rub at all? Will 225 rub at all?

Thanks,

 

If you're gonna stick with 17s then I would do the stock setup of 215/45/17. If you're not lowering your car then 225s would work fine and I believe you won't have a problem with 235s either, but I can't be sure on that one.

The middle number is the profile or thickness of the tire. The lower the number the thinner the tire will be. And I wouldn't go any lower than 45 because you will have alot of fender gap and it will look ugly on the car.

I'm getting an Si coupe tomorow and want the 18 inch alloys with the corresponding tires. From what i understand, you feel that 215/40<U></U> 18 tires (Kuhmo ASX) aren't the best choice? The 40<U></U> 18s are the "reccomended" size for the upgraded wheels from what the dealrs/tirerack.com are saying.

Not sure who to believe. What gives?

 

so for sure 225 will not have any rubbing/fitment issues if I'm not going to lower my car AT ALL, right?

Thanks! I guess I'll stick with the 45....does anyone know how high I can go with stock height and still be ok? thanks

 

I have 225/40/18 on HFP rims, on HFP suspension (about 1" drop). I have no rubbing issues.

 

Absolutely gorgeous dude. I'm taking that route in 2 days when i pick mine up. No kit or lowering though, plus flaps. wonder what THAT'LL look like.

 

So, can someone help: will 225/45/17 have ANY issues with stock wheels, stock Si height, suspension whatsoever? thanks!

 

or should i stick with 215/45/17.... or 225/40/17.... thanks

 

225/45/17 will be fine. 215/45/17 will be fine.. either one you choose will be good whether your lowered or not.

If you don't plan on going lowering AT ALL, the max size you can push is a 255. A member on 8thcivic has it, but hes not lowered. it looks good that its wide, but sucks that if he lowers, he rubs.

 

I'd stick with the stock tire size if I was you. Larger sizes will surely fit, but you don't want a weak-er sidewall. If you go to the falken site, they list the tire sizes and what rim width they were measured on. That's how I buy my tires.

In this case, a Falken Azenis RT-615 215/45R17 was measured on a 7" wheel, and that's the wheel I'd go with.

That combo is fine. The OP stated he was staying with 17" wheels. Not 18s. But since YOU are getting an 18 inch wheel then you will not have a larger fender gap even though the profile is a little thinner because the overall circumference of the wheel is larger. A 215/40/18 tire will be very sligthly larger than a 215/45/17 tire when placed side by side. The lower profile is recommended because they are trying to keep you as close to the overall size of the factory setup as possible because the larger your circumference the more your speed will be off from what is showing on the speedometer.

For example a 215/40/18 tire will only result in the vehicle going about .37mph slower than what is read on the speedometer and is only 1/10 of an inch larger in diameter than a 215/45/17 tire so it's nearly identical. If you were to get a 215/45/18 tire then that would be a mistake because it would be a full inch larger in diameter and would result in a speed variation 3mph slower than what is read on the speedo. Not to mention it would make the car sit noticeably higher than stock because of the larger circumference.

Here's a comparison.....

Stock wheels..... 215/45/17



HFP wheels...... 215/40/18


Bottom line. Stick with the 215/40/18 setup if you're getting the HFP rims.

I wasn't going to be going with a 255 or recommending he go with it either.

I just thought I'd throw it out there in case anyone wanted to know. 215/225 is a good size to stick with though

 

thanks everyone. I guess I'll go with the 225/45/17

i guess i'll go with Azenis.. although i'm worried about driving in the rain...and hydroplaning. It rains a lot here in oregon.

 

i have 225 45 on my stockers and im lowered on eibach sportlines no rubbing issues
