Hey everyone! I'm in the market for a set of TC105N and I had some questions about the sizes. I want to have a 255/40/17 square setup and i think 17x9 +49 is the correct size, but i also wanted a little bit of concave for my rims and i know 17x9+35 will give me a nice concave but im worried about how much camber i need to fit those. Also, I've heard that 255 size tires fits even better on 17x9.5 because of the stiffer side walls. So my question is which of the following 3 sizes should i get; 17x9 +49, 17x9 +35, 17x9.5 +32. I want to be able to fit the rims with a roll/pull and tab relocate. I drive the car daily in the summer and the car does see track time so i'm debating if i should run more aggresive wheels with more camber, or just be conservative with 17x9 +49 and have the tires wear out slower. Thanks!!

17x9 +49 is your best and easiest fit for a 255, can be fitted with a roll (possibly relocate tabs) no pull and no aggressive camber. You could fit the 17x9 +35 but it'll be a lot of work; pull, roll, relocate tabs and aggressive camber. Even then, you'll be pushing it. The 17x9.5 +32 is out of the question stock bodied.

Thanks! What's considered aggresive camber? And will it reduce my tires' life span by a lot?

I would avoid the 9.5 +32. That's just a bit to aggressive. It can fit but you need to pull your fender a good deal and also run over 3 hm degrees of camber. The 9 +35 is much more doable. Again 3 ish degrees of camber and rolled fenders. The +49 is the best for the front. Those other 2 specs will not work on the front.

Anything above -3

It reduces the contact patch of the tire to road surface, causing poor breaking and acceleration grip, and in more severe settings, corky handling. If your running standard toe alignment on the car, coupled with this amount of camber or more, you will be wearing out the insides of the tires very quickly, and flipping them will be common practice just to try and preserve some level of life, but it will still be diminished.

Is that for both front and rear? Will 17x9 +35 need 3 isn degrees for the rear?

So if i were to run +49 front +35 rear, will that be a bad choice because the camber in the rear will upset the balance of grip when accelerating and braking?

No that stagger should be ok. Depending on how good the fender roll is you may be able to get away with under 3 degrees of camber. What do you mean for both the front and rear.

It will to a degree if your running the same size rubber all the way around. One other aspect is visually, the difference in offset from front to rear is pretty wide, so the front fitment is going to look pretty good fitting, wile the rear is going to look hellaflush. Something in the +40/+45 out back to go with the +49 up front would be a nicer mate, and also wont limit you to a 245 out back, or max camber which you will need if you try and cram on a 255. If you cant get that offset stagger then run the same +49 all the way around and stager the tires. 245 up front/255 in the rear. It will look better and functionally be light years ahead of the alternative compromises. I think if your lowered much at all, your going to have some outer rubbing issues with a 255 up front on just a 9" rim at +49. Plan on pulling the front a bit and compromising your tire life with camber.

Like i mean will both front and rear need around 3 degrees of camber if i run 17x9 +35 square? Or will the rear need a little bit less since it has more clearance
