Ok... I decided I'm going to buy a set of 18 x 9.5/18 x 10.5" C6 Z06 wheels to give my car the right look with it's new paint coming this winter. I decided to finally go wide in the back, because I've got for traction at this point. M6, 3:90 rear, 420ish rwhp (470 by the time I'm done modding)... I might as well have a sheet of ice on my 275 Sumitomos in the back right now.

I'm looking for tires now (Tomzwheels hooked it up sweet on the wheels). I wanted to run a 275 in the front and a 315 in the back, but tire choices are very limited.

Here's the relevant tire sizes I can find:

275/35/18 (25.58" diameter, the obvious choice for the front)
275/40/18 (26.66" diameter)
285/35/18 (25.85" diameter)
295/35/18 (26.13" diameter)
315/30/18 (25.44" diameter, only available in Michelin, Yokohama, Pirelli, and other competition/drag radials, all very expensive)
335/30/18 (25.91" diameter, I love it, just don't think it'll fit the fenderwell or the rim)

Imaginary sizes I wish someone made:

315/35/18 (26.68" diameter, perfect match for the 275/40/18s )

The car is stock height now, but will soon be lowered on Hotchkis or a Prokit.

So what's my best option here, guys? I need some more traction, without completely breaking the bank. I had BFG KDWs in mind, but it looks like that's out unless I run the 295s or the 335s in the rear. Can't use drags or comp tires, it's a DD. What are the rest of you running? I'd hate to put 295s on and have them look too small for the rim.

Any advice? I've searched until I'm turning blue at this point.

Edit: Yes, I already have an adjustable PHB

I run 275/35ZR18 front and 295/35ZR18 rear. Happy with the selection.

Thanks, does anyone know what the widest 295s are?

If you want cheap 315s then the sumitos or whatever are $100 a piece.. but for the power your putting down I don't think itll help much. If you want traction and you want wide tires then you should have figured out that tires would be expensive before you got wide wheels... If you want to hook with street tires decently your going to need to shell out a good penny for GOOD street tires.

Xsta Z 28 is running a nice combo there....and traction isn't only about tires, if you don't have the proper suspension parts along with them... tires alone aren't going to do much for you.

I can't run Sumitomos... not on 18's. I chose the wheels because I like the way they look. I'm just trying to figure out what tires will be best on them. If I have to end up coughing up $400/tire, I will. I'm just trying to see what others are doing, because I know there's quite a few of us running 18 x 10.5" wheels on the back, and I know that not all of them can afford to run $400+ PS2s.

Same here.

Yeah, I know tires aren't going to do everything, but they can definitely help. I've got a decent suspension, though. UMI Tunnel Mount Adj TA, Spohn LCAs, and Adj PHB. More will be done in the future, but that's where it stands for now. Next upgrade is probably Hotchkis/SLP Bilsteins.

i just bought some c5z06's with the 295 eagle f1's on the car. havent really tested the traction yet, so far they are really nice and ride well. not sure how much they are or anything so i couldnt tell you

jmdale1984

iTrader: (6)

Looks awesome. Thanks for the pics. I think I'm sold on those KDW2s. How does it hook compared to 275s?

.07" difference on top and bottom isn't very noticeable at all.

I run 275/35r18's up front and 315/35r18 BFG DR's on the rear. I have Stranos on the rear. So, as long as your offset is right they fit with the BFH. FYI-I had your goal of 470 RWHP (until the motor let go). I liked them, but with a couple of dragstrip runs I could watch the tread disappear!

I prefer 275 fronts and 295 rears on f-bodies. The extra width isn't worth the hassle if you are concerned with just visuals. Tire brand means more than width when it comes to traction.

If you are that concerned with visuals, some nicer multi-piece wheels with a fat rear lip would have been far more visually enhancing than just tire width.

Thanks for chiming in. That makes sense to me, 275/295s it is!

I actually really LOVE the C6 Z06 wheels in satin black, and I don't know if I'd change them even if I was given some nicer forged wheels. Plus, I don't have Nine Ball money, I have jmdale1984 money

Why has no one mentioned this yet?

305/35-18 Nitto Drag Radial for the back, 275/35-18 Nitto NT555 for the front. Tires match, 305s out back, taller tire, everything you want.

To everyone who thinks that the Nittos are just the skinniest tires in the world that just is not true, a 305mm Nitto is a wide tire and will look nice out back.

When I get around to getting new wheels and tires it will be a 265/35-18 and 315/30-18 BFG combo, both are similar in height and I want the wide 315s out back.

Because he said DR's wouldn't work because this is his DD. I used to run DR's on my Mach DD and it got expensive. Even when I was not spinning the rubber off it was just wearing off about every 2 months.

jmdale1984

iTrader: (6)

Yeah... no DRs for me. I'm just throwing some slicks on a set of 16's that are laying around for the track.

If you can find a 315/30/18 BFG, then let me know. All I can find in that size are (street tires):

Hankooks
Michelin PS2s
Yokohama Advans
Pirellis

All of those are either too expensive, with too little wear, or junk... think I'm better off with the KDW2s in a 295.

Me too, I love them

In that case:

You could also do a Nitto Invo in a 275/35-18 and 295/35-18. Good street tire and less expensive than the BFG.
