I would throw a 275/40R18 on there

 

What do you guys think of Bridgestone Potenza RE760 Sport tires? I plan on getting 18x9.5+12 front and 18x10.5+22 rear with 265/35 and 295/35. Would you mix tire brands front and rear cause I can only find 4 tires brands that offer both the sizes I'm looking for. Or am I crazy and fail at searching on the googles.

 

IMO, 295/35 is too tall compared to 265/35 (10.5mm difference). I would go with 265/35 and 285/35, there should be more options so you don't have to mix brands.

 

Putting 285 on the back on a 10.5 rim wont give me that stretched look will it because I think that is the worst thing you can do. To keep a 295 on the back could I bump the front up to a 275 on a 9.5 rim without having to run horrid camber I am trying to do this without having to have absurd camber.

 

285 has a hair or stretch, if you could even call it that. It is a very optimal size for the wheel.

 

285mm = 11.2"

 

Thanks now to decide on what brand tires to go with off to the search bar again.

 

Wheel setup:

18x9.75 +20mm square

Stock height (maybe 1" drop or so in the future)

I'm thinking 255/35-18 front and 275/35-18 rear.

Should I stick with 35 series sidewall height? I don't have a burning desire to drop the car any time soon and want the majority of the fenderwell to be full. Any input appreciated.

 

255/35-18 never belongs on a Z . The proper for that with is 255/40 and 275/40. If you want 35's you need to go wider.

 

Got it. That's what I originally was thinking but I saw quite a few guys running 35 series sidewalls with similar widths and started to wonder.

 

i run the 275/40 255/40 combo, i like it

 

Here is what I decided on

Front: 18x9 +20 offset, 245/40/18
Rear: 18x9 +20 offset 5mm spacer, 265/40/18

Opinions anyone?
should I go 275/40/18 in the rear?

 

Yes and get 9.5/10.5 +22 in a different wheel.

 

If it was me with budget constraints, I would get a 10mm rear spacer and run a 265/40 on it , maybe even a 245/45 rear. Running a 275/40 rear will work, probably pretty good for drag, but the handling sucks. Really I wouldn't run a 275/40 on anything less than a 10 inch wife wheel.

 

Thanks for the response. Thats the kind of information I was looking for. Will it handle like ****? Yes. Then I wont do a 275 on a 9" wheel. Makes sense.

Once I get the tires I will see if I want to go 10mm on the spacer. I will start will the 5mm spacer since I don't have to change the lugs. For me, it's not so much the budget constraints. It just took me for ever to pick wheels. I like what I found.

 

I feel like I'm in a conundrum. I just bought an 06 touring with the most hideous wheels. I'm buying new 18" wheels and I want to conservatively push them out to the fenders. I want to be conservative, but still somewhat agressive. I've been looking at the Work CR KAi's or the knockoff Rota Torques in the 9.5 +20, but don't know if I want the 9.5 in the front. I think I really want the 8.5 in the front because I think it will fit the 245/40 tire better.

I am at stock height and will probably never drop the car.
Help me decide the right course of action here.

Options 1:

9.5 +20 all around with either:
245/40/18 f 275/40/18 r
or
255/40/18 f 275/40/18 r

If I do this option I'm worried the 245 will look stretched on the 9.5 wheel and I want a beefy tire. I'm also worried that 255 might rub or be too close to messing with the VDC. I did the calculations and think it should work but I'm not sure. The 245/275 combo seems to be much safer with the VDC and will not be stretched.

So if I go this option, which tire should I run?

2) (this would be my preference)
Go 8.5 +?? front and 9.5 +20 rear. (I don't know what the front offset should be): Then I would definitely go a 245/40/18 on the front.

Problem here is I don't know the proper front offset. From what I figure, if I want it to sit flush like the 9.5 +20's in the rear, there is a 12.7mm difference in width so I shoud get a 8.5 +12 or so. But nobody makes a +12 in a 8.5 that I can find in the wheels I want.

Did I calculate that completely wrong? If I want a 8.5/9.5 combo what 8.5 offset would look best with the 9.5+20?

What would you guys do?

 

255/40 coupled with a 275/40 is closer to stock as far as VDC is concerned. It is also not going to rub at 9.5 +20. The rear in 9.5 is fine, no roll required , but I would roll it and add a 10mm just for looks. If they offer a 10 inch wheel in that size, I would get that for the rear.

 

The 245/40/18 will be stretched on a 9.5 width wheel. They fit perfectly on a 8.5. Even the 255/40 is slightly stretched on a 9.5. You won't rub on the front either way you go.

 

most people wouldnt even see any stretch it is going to be VERY minimal

 

I agree, most people won't notice the 255, but the 245 is obvious on a 9.5 inch wheel.
