Ok good info, I am dead set on some 15x8 My car is lowered with Tanabe DF210 Does any one have 15x8 with this set up? and what would be the best offset? I am usually the only person in this car and the set up will be only for those extra special occasions (car shows, meets, etc...) I currently have some 15x6.5 and i see i have a some room to work with, so I am assuming no one has this set up yet, because It all sound like guesses to me (yes i am sure they are VERY educated guessses, none the less) If no definite answers are out there, i guess, I have to go the trial and error route.

Like I said, use the calculator and take some measurments. Your main concern is strut and inner fenderwell clearance in the front. It is going to rub. |

Clean up this forum? That would involve executing the tire nazi. Remember, you're the guy that things 7 and 8 inch wide wheels both running the same offsets, sit at the same place in the wheelwell. Relax buddy.

That's incorrect, a 225 sitting on a 15x8 ET38 will not sit in the same place as a 225 sitting on a a 15x7 ET38, what tire shop did you work at again? A 1" wider wheel will put roughly 13mm's more on either side of the tire, both on the shock side and the fender side.

I for one would love to cram a 15x8 with a 235 under my car, and I would be more than willing to modify the fender well to accommodate. Why? Grip. Sure, there are some downsides to a rim that wide, but I'll take the good with the bad.
Also, Rota makes their Slipstreams in a 15x8, 4x100 application. One of my favorite rims. Keep talking about this... what would it take to make it work without rubbing on a mild drop like what you get with TRD springs or NF210's. |

I hope this picture can help clear things up a bit: Black Yaris is saying that between 7" and 8" widths, the same width tire will remain in the same position if the offset is unchanged. Take a good look and you'll see this is true, just as nimble pointed out, the RIM will extend 13mm in BOTH directions, and the tire will remain centered. You're both agreeing on this part The tire will only be moved in or out if the offset is changed. So, the offset comes into play when calculating the distance between the outer edge of the tire, and the inner wheel well and outer fender. This is where things get tricky, as it is really a function of tire width and not rim width. AND REMEMBER! This is confusing, a smaller positive offset means that your wheel sticks OUT more than a bigger positive offset. It's hard to visualize this in your head, so look at this picture, it should clear things up: On my car I have 215 width tires, and the rim's offset is 42mm. Now, the front wheels stick out a little more than the back due to my disc brake's hub being a little thicker than stock and acting as a spacer. So, the effective offset for the front wheels is more like 40 or 38mm, and you can see this best in this picture: You can see, as far as 215 tires go, that's a perfect fit. If I had wider tires on it (235 or 245mm), they would not stretch inward so much relative to the rim, and I would definitely have some rubbing on the outer fender, in which case a bigger offset would be prefered, to tuck the wheel back in a little and achieve a flush fit on the outside. On the inside, though, the extra tire width and increased offset may cause some rubbing as a result, and that is where fender rolling comes into play, physically extending the volume in which the tire and wheel can move when the suspension is under load, or when the steering wheel is being turned. PS I hate this stuff, it confuses the hell out of me and gives me massive headaches, but that's the best way to learn

The reality is, were bickering over 7mm of offset when the rim is 25.4mm (1 inch) wider than the recommended 7 inches. Like Nimble said, that's adding about 13mm to both sides. 38mm, 45mm, and everything in-between WILL rub on both the inside and outside. You want to modify your car to squeeze 8 inch wheels under it, pick your poison.

Thanks Thomas... everybody in agreement now.... Largeorangefont, you see where I was coming from all along with the +38? When I was suggesting the +38, i neglected to add this is the just about the only offset you can run with real wide wheels AND TIRES... I just was not giving complete information, so I can see why you though I did not know what I was talkin about.... but then again, I was usually suggesting the widest tire i could when ppl asked tire sizes..... were one big <non tire Nazi> famay again :)
