Default Would Running 295/30/19 in the rear be too much?

Well if somone with good experience would chime in, it would be greatly appreciated.

I have some 9.5 and 10.5 wheels...I was originally thinking of 255/35/19 and 285/35/19...but I kind of want the Vredestein Ultrac Sessanta Tires...so I was thinking of going 255 in the fronts, and having 295/30/19 in the rear...would this pose any issues with VDC?

Go 275 in the front and 295 in the rear. I have used that combo. Fitment depends on your wheel offset and how much you lower your car.

You wil have to roll your fenders and run approx -1.5 or -2.0 camber to fit it. That's my experience.

well my rear camber is at 1.9 right now...rolling the fenders is no issue, ready to do that...but just worried about VDC and such...and handling...with such wide tires up front, won't I get more oversteer?

for autoX I run Front 295s and Rear 315's (rolled fenders in the rear) - works wonderfully! I would have liked to keep a square set-up, but there's no way of fitting a 315 up front...but w/ the Z's TQ, you can still get the car rotated.

You will get less understeer. The Z has a tendency to understeer. You won't have any problems with VDC.

You will still have a 20mm difference in width between front and rear , understeer will be the same as stock. The 255 305 combo you suggested your car will understeer like a school bus.

The difference in circumference is 75.40 mm. This may be pushing the limits of VDC.

Thanks for the pic dave...but if I ran 255...it would be a 35...thinking about doing 275/30 though...just worried it might be too wide for the front

I've got 265/30/19 F and 295/30/19 R on 9.5 and 10.5 +22 LE37T's...

No VDC issues and no problems up front with 265's, I think 275 would work too.

It really depends on a lot more than just the tire sizes. I have 245/35's front and 305/30's rear and it does not have understeer even at 1.1 cornering G's. Also the front and rear tires do not squeal.

+1 im running 255x35 fronts and 305x30 rears and it handles like its on rails. Plus mines sitting pretty low, just roll the fenders and your set.

hmm...I guess thats the dilemma now is on the fronts...295 on the rears for sure...fronts...probably leaning towards 265...since 265/295 will make the two tire circs both 2.7% smaller than stock...

Chad and Nitrouz thanks for posting the pictures. I think I'm sold on the 305s. I'm sure those gotta be intimidating to the cars behind you lol.
