hi guys i have a 2000 civic si i currently have struts and springs and adjustable camber kits. I want to put on enkei rpf1s possibly 16x8's. Sorry if this was mentioned before but i was wondering if this size will fit no problem, and if so what tire size and offset do you guys recommend to go with? the purpose of the wheels is handling. thanks again

 

The correct tire size for your car in a 16" wheel is 205/45-16, which are not approved for use on 8" wide wheels. However, you can probably use a 215/45-16, which are approved for use on an 8" wheel.

For offset, I can't answer with any real authority. Probably something in the 30-40 range would be best. To find the real truth, put the car up on jackstands, remove the existing wheel, and move the suspension through its range and measure.

 

thanks. Im putting 16x8s on though so id be going up a few sizes in tires

 

The RPF 1 4x100 in 16x8 is +38. Youll probably have to roll fenders and run a decent amount of camber. Might be better off sticking with a 7" wheel. Tires have way more effect on grip than wheel width. There are a good amount of 195/55/15 and 205/50/15 summer tires available.

 

i dont mind rolling fenders i just want a wide tire to gain more contact to the pavement. sizes i would probably do 235 45 16

 

Way too huge of a tire size.

Why do you want to kill acceleration by changing the final gearing so much? Not to mention throw the odometer and speedometer off. It will also probably cause serious rubbing issues if the car is lowered at all.

 

I've got a 2000 em1 and I'm running 215 45 16 for tires on 16x8 wheels. My offset is +34 or +37 (cant remember which). My rear fenders are very slightly rolled and the front isn't and I even still have my wheel well liners in there. I'm at about a 3 inch drop from stock on coilovers and I get no rubbing. My rear is cambered in approximately 3 degrees and my front is about 1.5 degrees. With my 16x8's I couldn't run hammer on wheel weights in back though. You will likely have to use stick-ons. I prefer those anyways so no big deal. Yours will be Enkie's though so that might make a difference. Here's what I ended up with lookswise.

this is before I lowered the front and cambered it in a little more..and again I have not experienced any rubbing as long as I don't run the hammer on bead weights.

 

thats sexy for one^^^ and for two what you guys think of a 225 45 16 0n a 8 inch rim then? I just want a wide tire and I have adjustable camber kits so that shouldnt be a problem at all. thanks for the help once again its appreciated.

 

a wider tire like that shouldn't be too much of a problem in back. Where you'll find an issue would be in front. I'm not sure how much more room I have in front when I turn my wheels but I can only imagine it's not much. 225 45 is kinda big, although they would fit a 16x8 better than my tires. Mine are kinda stretched which I prefer but alot of people hate. to each his own but I think if you go much bigger then 225 you'll have issues. really depends on how low you'll be too.

 

damn I wonder if 235 40 16 would fit? I see where you guys are saying about the front though

 

Why are you trying to run such a wide tire? It won't offer any traction advantage.

If you really want the wider tire look, run a 225/45-15. No one makes a 235/40-16 that I can find, or even a 225/40-16.

 

Like I said i want the best tire size for a 8 inch rim x 16 that is offered. whats your recommendations for that then/?

 

I currently use a 205/45-16 on a 16x7 for my Integra, but will be going to 215/45-16 soon. Both very similar in size, and most brands come in one or the other size but not both. Our cars use the same sized tires.

The 8" wheel is limiting your tire selection, but plenty of good tires come in 215/45-16.

 

Is this thread a joke?
16x8 is going to give you some horrible handling. You'll get good handling with 235 but not only will your car look silly, it will have MASSIVE rubbing issues. 16x8's look good on.a slammed vehicle with a lot of negative camber, which I doubt you'll want to use at the track.
Stick with a 7" rim. Get 16x7 +40 offset and 215/45/16 tire or get a 15x7 with 205/55/15 tire.
You won't have rubbing issues and you'll be able to finely tune your suspension without doing crazy adjustments.

 

thanks for all the info guys, what you think of a 225 45 16? on a 7 or 7.5 inch rim?

 

Stock offset is 45

 

I think its asking for clearance/rubbing issues, as well as screwing with odometer and speedometer readings, for no gain.

If you want more traction, buy better tires.

I also think if you don't understand why I recommended a smaller diameter size that matches (or comes close to) the OEM diameter, you won't listen to any other valid advice anyway; so you should do what you please and deal with the consequences without asking anything more.

No offense intended. Its your car, do as you please, etc... There is much more information concerning this in the wheel/tire forum.

 

Couldnt have said it any better.
