I have Volk CE28's 18x9.5 w/ offset 34. I'm currently running 265's out back but can't hook up until 3rd gear.
What is the widest I can go?
Thanks guys.

What are the widest tires I can use with my wheels?

I think you are going to be limited to a 285 on a 9.5", anything wider usually specs a 10"+ rim. More importantly is the compound of the tire than the width. You can get a 285/30/18 in the AD08 which is going to be about as "sticky" as you can get without going to a R-Comp. They do make a 295 but spec shows 10-11" rim.
What tires are you currently running?

I think mine are Yokohama avs sport?
My buddy has Nitto NT-01's on his MR2. Those things are super sticky!
Back in 2010 he used to have the All Season Clear HP166.
Hopefully he changed them out, but if not that's definitely the reason.
NT01s are nice and sticky.. but don't last that long and are pretty noisy on the streets. I would also avoid driving them in the rain too...

I know that the manufacturer recommends differently, but I'm seeing alot of guys running MT 305/35/18s on a 18 9.5 without buldging. Will those fit inside the NSX wheel tubs?
Yeah, those have been gone for awhile.
Even when the car was stock, they made the car feel alot faster than it was. :biggrin:
315! Holy moly! Thanks for the link! <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com

Now, I'm not sure how all this translates. With my wheel size and offset, would the 305 fit the body? Or does offset even matter when choosing a tire? <o></o>

Offset doesn't matter when choosing a tire. Tire only cares about diameter and width of the wheel.
Offset only effects how the wheel will fit and clear the suspension and brakes.
See how the width is the same (A). Offset determines whether the center of the rim sits in closer to the suspension or further out towards the fender. You need an offset that will clear the suspension and brakes but not be too far out to stick past the fender.
Thanks, good to know. So, you think I would be ok with trying the 305/35/18's ?

This guy is running MT 305/35/18’s on his stock 9.5 wide wheels. It doesn’t seem to be buldging too bad.
I think you're totally missing the point here. As Jim said, what really matters for traction is the make/model of the tire (as reflected in its design, including compound, tread pattern, etc), not the width. The reason you're not getting traction is because you're using the AVS Sport, which is an older (no longer produced) not-very-sticky tire that Yokohama used to make. In the exact same size, slap on some "extreme performance" tires, like the Star Spec, RE-11, or Yokohama's own AD08, and you'll get way more traction. I'd just go with the standard 265/35-18. You'll be amazed at the difference. Go any wider, and it's only going to give you a slight difference, primarily in cornering, and not in straight-line acceleration, which is what it sounds like you care about. All you need is a really sticky rear tire in the 265/35-18 size. And oh yeah, you'll also need some really sticky front tires, unless you're only using these at the dragstrip; otherwise your car will have massive understeer if you have the AVS Sport in front and an extreme performance tire in the rear.
Assuming you have 17's on the front, here are extreme performance tires that are available in 215/40-17 for the front and 265/35-18 for the rear:
Dunlop Direzza Sport Z1 Star Spec
Yokohama Advan Neova AD08
Falken Azenis RT-615K

I completely understand that it's the type of tire, not the size. But, if I'm buying new tires and I can go wider, then I'll go wider.
Here are the tires I'm considering. They are 305/35/18's.

And yes, I'm more of a straight line guy.

Not necessarily true. If you have a given wheel, say 18x9.5 w/ offset 34.. 34 offset represents the centerline of the wheel (and the centerline of the tire). If you had a 18x11 +34, the centerline of the wheel will be exactly the same as on the 9.5", however the inside & outside edges of the wheels will be .75" wider on the 11" wide wheel.
Offset will be important when choosing significantly wider tires than what you currently running. Assuming 18x9.5" +34 is flush with the fender with a 265 tire, than running a 305 tire on the same wheel will add ~20mm of additional tread to the outside wheel edge (and 20mm on the inside edge). That means that the tire will stick out ~20mm MORE. So in this case, OFFSET IS IMPORTANT. The specs are all important in terms of tire fitment and flushness.
Offset only effects how the wheel will fit and clear the suspension and brakes.
See how the width is the same (A). Offset determines whether the center of the rim sits in closer to the suspension or further out towards the fender. You need an offset that will clear the suspension and brakes but not be too far out to stick past the fender.
The only thing that offset definitely determines is whether the center of the rim sits in closer to the suspension or further out towards the fender.
Offset does NOT necessarily determine if it will clear the brakes. This is determined more by the wheel design or "disk type". The diagram posted is somewhat misleading because it shows wheels with different disk types and not all wheels are made this way. Case in point: 2 piece wheels will move a given disk type along the barrel to determine offset.
I go into much more detail in this Wiki Article they created from one of my earlier threads:

It's painter's tape. I've seen people run it at the track, either to cover up glass lenses, or to protect body panels in exposed areas, or just for the sake of appearance.
Ken,
Are those tires listed in your order of preference? I stockpiled a few sets of F1-GSD3s a while back and I am about to mount up my last set of rears. I tend to go through 2 sets of rears for one set of fronts. Now that the GSD3 is extinct, I'm soon going to be looking for its successor for Charlotte. Since you know how much mileage I do and that it rains a lot down here in the summer I'm curious as to which tire you'd recommend. My early inclination is to go with the Star Specs.
